Change Order: All changes to the Contract Documents that include a change in the Contract Price or the Contract Times for previously authorized Work, or changes to the Work requiring Designer's approval must be made by a Change Order. A Change Order may also be used to establish modifications of the Contract Documents that do not affect the Contract Price or Contract Times. 3. Work Change Directive: A Work Change Directive does not change the Contract Price or the Contract Times, but is evidence that the parties expect that the modifications ordered or documented by a Work Change Directive will be incorporated in a subsequently issued Change Order following negotiations on the Contract Price and Contract Times. If negotiations under the terms of the Contract Documents governing adjustments, expressly including Paragraphs 11.04 and 11.05 are unsuccessful, Contractor must submit a Change Proposal seeking an adjustment of the Contract Price or the Contract Times no later than 30 days after the completion of the Work set out in the Work Change Directive. 4. Field Order: Designer may require minor changes in the Work that do not change the Contract Price or Contract Times using a Field Order. OAR may issue a Field Order for non-technical, administrative issues. Submit a Change Proposal if Contractor believes that a Field Order justifies an adjustment in the Contract Price or Contract Times before proceeding with the Work described in the Field Order. B. Perform added or revised Work under the applicable provisions of the Contract Documents for the same or similar Work unless different Drawings, Specifications or directions are provided in the Modification. 11.02 Owner-Authorized Changes in the Work A.

Involves acceptance of the Work; or 3. Involves other engineering, architectural or technical matters. B. These changes may be authorized by a Modification. Proceed with the Work involved or, in the case of a deletion in the Work, immediately cease construction activities with respect to the deleted Work upon receipt of the Modification. Nothing in this paragraph obligates the Contractor to undertake Work that Contractor reasonably concludes cannot be performed in a manner consistent with Contractor's safety obligations under the Contract Documents or Laws and Regulations. 11.03 Unauthorized Changes in the Work A. Contractor is not entitled to an increase in the Contract Price or an extension of the Contract Times with respect to Work performed that is not required by the Contract Documents, except in the case of an emergency as provided in Paragraph 7.12, or in the case of uncovering Work as provided in Paragraph 16.05.

Any Claim for an adjustment of Contract Price must comply with the provisions of Article 13. B. An adjustment in the Contract Price is to be determined as follows: 1. By applying unit prices to the quantities of the items involved, subject to the provisions of Paragraph 15.03, where the Work involved is covered by unit prices in the Contract Documents; 2. By a mutually agreed lump sum where the Work involved is not covered by unit prices in the Contract Documents; or 3. Payment on the basis of the Cost of the Work determined as provided in Paragraph 15.01 plus a Contractor's fee for overhead and profit determined as provided in Paragraph 15.05 when the Work involved is not covered by unit prices in the Contract Documents and the parties do not reach a mutual agreement to a lump sum. C. The original Contract Price may not be increased by more than 25 percent or the limit set out in Texas Local Government Code 252.048 or its successor statute, whichever is greater. Owner may decrease the Work by up to 25 percent of the Contract Price. 11.05 Change of Contract Times A. The Contract Times for authorized Work can only be changed by Change Order. Any Change Proposal for an adjustment in the Contract Times must comply with the provisions of Paragraph 11.06.

Agreed to by the Owner and Contractor; and 4. Changes in the Contract Price or Contract Times, or other changes under Paragraph 11.06 or Article 13. B. Acceptance of a Change Order by Contractor constitutes a full accord and satisfaction for any and all claims and costs of any kind, whether direct or indirect, including but not limited to impact, delay or acceleration damages arising from the subject matter of the Change Order. Each Change Order must be specific and final as to prices and extensions of time, with no reservations or other provisions allowing for future additional money or time as a result of the particular changes identified and fully compensated in the Change Order. The execution of a Change Order by Contractor constitutes conclusive evidence of Contractor's agreement to the ordered changes in the Work. This Contract, as amended, forever releases any claim against Owner for additional time or compensation for matters relating to or arising out of or resulting from the Work included within or affected by the executed Change Order. This release applies to claims related to the cumulative impact of all Change Orders and to any claim related to the effect of a change on unchanged Work. C. All Change Orders require approval by either the City Council or Owner by administrative action. The approval process requires a minimum of 45 days after submission in final form with all supporting data. Receipt of Contractor's submission by Owner constitutes neither acceptance nor approval of a Change Order, nor a warranty that the Change Order will be authorized by City Council or administrative action. The time required for the approval process may not be considered a delay and no extensions to the Contract Times or increase in the Contract Price will be considered or granted as a result of the process. Contractor may proceed with Work if a Work Change Directive is issued. D. If the Contractor refuses to execute a Change Order that is required to be executed under the terms of this Paragraph 11.07, the Change Order is deemed to be in full force as if executed by Contractor. Contractor may file a Claim for payment and/or time, pursuant to Article 13.

The allocation for delays in the Contractor's progress for rain days as set forth in General Conditions Paragraph 4.04.D are to be determined as follows: 1. Include rain days in developing the schedule for construction. Schedule construction so that the Work will be completed within the Contract Times assuming that these rain days will occur. Incorporate residual impacts following rain days such as limited access to and within the Site, inability to work due to wet or muddy Site conditions, delays in delivery of equipment and materials, and other impacts related to rain days when developing the schedule for construction. Include all costs associated with these rain days and residual impacts in the Contract Price. 2. A rain day is defined as any day in which the amount of rain measured by the National Weather Services at the Power Street Stormwater Pump Station is O.SO inch or greater.

Union Rate Identifiers A four letter classification abbreviation identifier enclosed in dotted lines beginning with characters other than ""SU"" or ""UAVG"" denotes that the union classification and rate were prevailing for that classification in the survey. Example: PLUM0198-005 07/01/2014. PLUM is an abbreviation identifier of the union which prevailed in the survey for this classification,which in this example would be Plumbers.0198 indicates the local union number or district council number where applicable, i.e., Plumbers Local 0198.The next number, 005 in the example, is an internal number used in processing the wage determination. 07/01/2014 is the effective date of the most current negotiated rate,which in this example is July 1, 2014. Union prevailing wage rates are updated to reflect all rate changes in the collective bargaining agreement(CBA)governing this classification and rate. Survey Rate Identifiers Classifications listed under the ""SU"" identifier indicate that no one rate prevailed for this classification in the survey and the published rate is derived by computing a weighted average rate based on all the rates reported in the survey for that classification.

Contractor shall coordinate with the Owner on all testing. Tests will also be performed as each new area of construction is started. F. Another option for disposal of groundwater by Contractor would include pumping to the nearest wastewater system. If discharging to temporary holding tanks and trucking to a wastewater or wastewater plant, the costs for these operations shall be negotiated. Other groundwater disposal alternatives or solutions may be approved by the Designer on a case by case basis. G. Prior to pumping groundwater from a trench to the wastewater system the Contractor shall contact Wastewater Pre-treatment Coordinator at 826-1817 to obtain a "no cost" permit from the Owner's Waste Water Department. Contractor will pay for any water quality testing or water analysis cost required. The permit will require an estimate of groundwater flow. Groundwater flow can be estimated by boring a hole or excavating a short trench then record water level shortly after completion, allow to sit overnight, record water level again, pump hole or trench dry to a holding tank or vacuum truck then record how long it takes to fill to original level and overnight level. 1.12 DISPOSAL OF CONTAMINATED GROUNDWATER (NOT APPLICABLE) A. An allowance will be included in the Bid for the unanticipated disposal of contaminated groundwater. This allowance may not be needed but is provided in case contaminated groundwater is encountered during the course of the Project and does not meet the water quality requirements for discharge into the storm water or wastewater systems. This allowance includes all materials, tools, equipment, labor, transportation, hauling, coordination, and proper disposal of the contaminated water at an approved landfill, deep water injection well, or other site as agreed to by the Designer. Suggested disposal facilities would be [US Ecology (USET) in Robstown, Texas or Texas Molecular in Corpus Christi, Texas]. B.

DESCRIPTION This specification shall govern all work for excavation and backfill for utilities required to complete the project. 2. CONSTRUCTION (1) Unless otherwise specified on the drawings or permitted by the Engineer, all pipe and conduit shall be constructed in open cut trenches with vertical sides. Trenches shall be sheathed and braced as necessary throughout the construction period. Sheathing and bracing shall be the responsibility of the Contractor (refer to Section 022022 "Trench Safety for Excavations" of the City Standard Specifications). Trenches shall have a maximum width of one foot beyond the horizontal projection of the outside surfaces of the pipe and parallel thereto on each side unless otherwise specified. The Contractor shall not have more than 200 feet of open trench left behind the trenching operation and no more than 500 feet of ditch behind the ditching machine that is not compacted as required by the plans and specifications. No trench or excavation shall remain open after working hours. For all utility conduit and sewer pipe to be constructed in fill above natural ground, the embankment shall first be constructed to an elevation not less than one foot above the top of the pipe or conduit, after which excavation for the pipe or conduit shall be made. If quicksand, muck, or similar unstable material is encountered during the excavation, the following procedure shall be used unless other methods are called for on the drawings. If the unstable condition is a result of ground water,the Contractor,prior to additional excavation, shall control it. After stable conditions have been achieved,unstable soil shall be removed or stabilized to a depth of 2 feet below the bottom of pipe for pipes 2 feet or more in height;and to a depth equal to the height of pipe, 6 inches minimum,for pipes less then 2 feet in height. Such excavation shall be carried at least one foot beyond the horizontal limits of the structure on all sides. All unstable soil so removed shall be replaced with suitable stable material, placed in uniform layers of suitable depth as directed by the Engineer,and each layer shall be wetted, if necessary, and compacted by mechanical tamping as required to provide a stable condition. For unstable trench conditions requiring outside forms, seals, sheathing and bracing, any additional excavation and backfill required shall be done at the Contractor's expense. (2) Shaping of Trench Bottom. The trench bottom shall be undercut a minimum depth sufficient to accommodate the class of bedding indicated on the plans and specifications. 022020 Page 1 of 4 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 (3) Dewatering Trench. Pipe or conduit shall not be constructed or laid in a trench in the presence of water. All water shall be removed from the trench sufficiently prior to the pipe or conduit planing operation to insure a relatively dry (no standing water), firm bed. The trench shall be maintained in such dewatered condition until the trench has been backfilled to a height at lease one foot above the top of pipe. Removal of water may be accomplished by bailing,pumping, or by installation of well-points,as conditions warrant. Removal of well- points shall be at rate of 1/3 per 24 hours (every third well-point). The Contractor shall prevent groundwater from trench or excavation dewatering operations from discharging directly into the storm water system. Groundwater from dewatering operations shall be sampled and tested, if applicable, and disposed of, in accordance with City Standard Specification Section 022021 "Control of Ground Water". (4) Excavation in Streets. Excavation in streets,together with the maintenance of traffic where specified, and the restoration of the pavement riding surface, shall be in accordance with drawing detail or as required by other applicable specifications. (5) Removing Abandoned Structures. When abandoned masonry structures or foundations are encountered in the excavation, such obstructions shall be removed for the full width of the trench and to a depth one foot below the bottom of the trench. When abandoned inlets or manholes are encountered and no plan provision is made for adjustment or connection to the new utility,such manholes and inlets shall be removed completely to a depth one foot below the bottom of the trench. In each instance,the bottom to the trench shall be restored to grade by backfilling and compacting by the methods provided hereinafter for backfill. Where the trench cuts through utility lines which are known to be abandoned, these lines shall be cut flush with the sides of the trench and blocked with a concrete plug in a manner satisfactory to the Engineer. (6) Protection of Utilities. The Contractor shall conduct his work such that a reasonable minimum of disturbance to existing utilities will result. Particular care shall be exercised to avoid the cutting or breakage of water and gas lines. Such lines, if broken, shall be restored promptly by the Contractor. When active wastewater lines are cut in the trenching operations, temporary flumes shall be provided across the trench while open, and the lines shall be restored when the backfilling has progressed to the original bedding line of the sewer so cut. The Contractor shall inform utility owners sufficiently in advance of the Contractor's operations to enable such utility owners to reroute, provide temporary detours, or to make other adjustments to utility lines in order that the Contractor may proceed with his work with a minimum of delay. The Contractor shall not hold the City liable for any expense due to delay or additional work because of utility adjustments or conflicts. (7) Excess Excavated Material. All materials from excavation not required for backfilling the trench shall be removed by the Contractor from the job site promptly following the completion of work involved. 022020 Page 2 of 4 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 (8) Backfill A.

Monitor and record average flow rate of operation for each deep well, or for each wellpoint or eductor header used in dewatering system. Also monitor and record water level and ground water recovery. These records shall be obtained daily until steady conditions are achieved, and twice weekly thereafter. 022021 Page 6 of 10 Rev.10-30-2014 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 B. Observe and record elevation of water level daily as long as ground water control system is in operation, and weekly thereafter until the Work is completed or piezometers or wells are removed, except when City Engineer determines that more frequent monitoring and recording are required. Comply with Construction Inspector's direction for increased monitoring and recording and take measures as necessary to ensure effective dewatering for intended purpose. 3.6 SAMPLING, TESTING AND DISPOSAL OF GROUND WATER A. It is the intent that the Contractor discharge groundwater primarily into the existing storm water system in accordance with City Ordinance, Article XVI, Section 55-203, only if the groundwater is uncontaminated and the quality of the ground water is equal to or better than the quality of the receiving stream. B. The Contractor shall prevent ground water from trench or excavation dewatering operations from discharging directly into the storm water system prior to testing and authorization. Ground water from dewatering operations shall be sampled and tested, and disposed of by approved methods. C. Laboratory analysis of groundwater and receiving water quality is to be performed by the Contractor at the Contractor's expense, prior to commencing discharge, and groundwater analysis shall be performed by the Contractor at a minimum of once per week. Contractor shall coordinate with the City Storm Water Department on all laboratory analysis. Laboratory analysis of groundwater shall also be performed at each new area of construction prior to discharge from that location. D. Sample containers, holding times,preservation methods, and analytical methods, shall either follow the requirements in 40 CFR Part 136 (as amended), or the latest edition of"Standard Methods for the Examination of Water and Wastewater." Any laboratory providing analysis must be accredited or certified by the Texas Commission on Environmental Quality according to Title 30 Texas Administrative Code (30 TAC) Chapters 25 for the matrices,methods, and parameters of analysis, if available, or be exempt according to 30 TAC §25.6. E. Analysis of the ground water discharge shall show it to be equal to or better than the quality of the first natural body of receiving water. This requires testing of both the receiving water and a sample of the ground water. All parts of this procedure shall be complete prior to any discharge of ground water to the storm water system. F. Steps to Determine Legitimate Discharge: 1. Identify the First Receiving Water. a) When the first body of water is a fresh water system (Nueces River or Oso Creek), the analysis typically fails because the local ground water will likely be too high in Total Dissolved Solids (TDS). In the case of a perched aquifer, the ground water may turn out fairly fresh, but local experience shows this to be unlikely. b) If the receiving water is a marine environment,proceed with Step 2 below to compare the ground water quality to receiving water quality. 022021 Page 7 of 10 Rev.10-30-2014 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 2. Compare Ground Water Discharge Quality to Receiving Water Quality. The following table, Ground Water Discharge Limits, indicates that the parameters to compare to the receiving water are Total Dissolved Solids (TDS) and Total Suspended Solids (TSS). If the ground water results are equal to or better than the receiving water, then the discharge may be authorized as long as the discharge does not exceed the other parameters which would indicate hydrocarbon contamination. Note that the receiving water only needs to be tested initially as a baseline and the ground water shall be tested weekly to ensure compliance. GROUND WATER DISCHARGE LIMITS Ground Receiving Water Water Monitoring Monitoring Maximum Parameter Frequency Frequency Limitation Total Dissolved Once Prior to Solids (TDS) Initial +Weekly Discharge <Receiving Water Total Suspended Once Prior to Solids (TSS) Initial+Weekly Discharge <Receiving Water Total Petroleum Hydrocarbons Initial +Weekly 15 m /L Total Lead Initial +Weekly 0.1 m /L Benzene Initial +Weekly 0.005 mg/L Total BTEX Initial +Weekly 0.1 m /L Polynuclear Aromatic Hydrocarbons Initial +Monthly 0.01 m /L 3. Analyze Ground Water for Hydrocarbon Contamination. All other parameters listed on the Ground Water Discharge Limits table must be analyzed prior to ground water discharge to the storm water system. If no limits are exceeded, ground water discharge to the storm water system may be authorized following notification to the MS4 operator (City of Corpus Christi) and all Pollution Prevention Measures for the project are in place. Analytical results shall be on-site or readily available for review by local, state or federal inspectors. Note that this step is frequently done simultaneously with Step 2 above to shorten analytical processing time. 4. Pollution Prevention Measures. A storm water pollution prevention plan or pollution control plan shall be developed and implemented prior to any ground water discharges to the storm water system. The plan's objectives are to limit erosion and scour of the storm water system, and minimize Total Suspended Solids (TSS) and other forms of contamination, and prevent any damage to the storm water system. Note that ground water discharges must cease immediately upon the first recognition of contamination, either by sensory or analytical methods. If the discharge of groundwater results in any damages to the storm water system, the responsible party 022021 Page 8 of 10 Rev.10-30-2014 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 shall remediate any damage to the storm water system and the environment to the satisfaction of the Storm Water Department and/or any State or Federal Regulatory Agency. 5. MS4 Operator Notification. The MS4 operator shall be notified prior to ground water discharge to the storm water system. Contractor shall contact the designated City MS4 representative to request authorization to discharge ground water to the storm water system. Notification shall include: Project Name: Responsible Party: Discharge Location: Receiving Water: Estimated Time of Discharge: Linear Project: Yes/No Pollution Prevention Measures Implemented: Statement indicating all sampling and testing has been conducted and meets the requirements of a legitimate discharge. G. Discharges to Wastewater System In the event that the groundwater does not equal or exceed the receiving water quality, an alternative disposal option would include pumping to the nearest sanitary sewer system. Discharge to the sanitary sewer system requires a permit from the Wastewater Department. If discharging to temporary holding tanks and trucking to a sanitary sewer or wastewater treatment plant, the costs for these operations shall be negotiated. Contractor shall contact the Pretreatment Group for City Utility Operations to obtain a Wastewater Discharge Permit Application for authorization to discharge to the wastewater system. Authorization approval will include review of laboratory analysis of the ground water and estimated flow data. Note that groundwater discharges must cease immediately upon the first recognition of contamination, either by sensory or analytical methods. If the discharge of groundwater results in any damages to the wastewater collection system or wastewater overflows, the responsible party shall remediate any damage to the wastewater collection system and the environment to the satisfaction of the Wastewater Department and/or any State or Federal Regulatory Agency. H. Other groundwater disposal alternatives or solutions may be approved by the Engineer on a case by case basis. 3.7 SURFACE WATER CONTROL A. Intercept surface water and divert it away from excavations through the use of dikes, ditches, curb walls, pipes, sumps or other approved means. B. Divert surface water into sumps and pump into drainage channels or storm drains, when 022021 Page 9 of 10 Rev.10-30-2014 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 approved by the City Engineer. Provide settling basins when required by the City Engineer. C. Storm water that enters the excavation can be pumped out as long as care is taken to minimize solids and mud entering the pump suction and flow is pumped to a location that allows for sheet flow prior to entering a storm water drainage ditch or storm water inlet. An alternative to sheet flow is to pump storm water to an area where ponding occurs naturally without leaving the designated work area or by manmade berm(s)prior to entering the storm water system. Sheet flow and ponding is required to allow solids screening and/or settling prior to entering the storm water system. Storm water or groundwater shall not be discharged to private property. 4. MEASUREMENT AND PAYMENT Unless otherwise specified on the Bid Form, control of ground water will not be measured and paid for separately,but shall be considered subsidiary to other bid items. 022021 Page 10 of 10 Rev.10-30-2014 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 SECTION 022022 TRENCH SAFETY FOR EXCAVATIONS 1.

DESCRIPTION This specification shall govern all work for Embankment required to complete the project. 2. CONSTRUCTION METHODS Prior to placing embankment, the area to be covered shall be stripped of all vegetation and the material so removed shall be disposed of off the job site. Washes, gulleys, wet areas, and yielding areas shall be corrected as directed by the Engineer. Unless otherwise indicated on the drawings, the surface of the ground which is to receive embankment shall be loosened by scarifying or plowing to a depth of not less than 6 inches. The loosened material shall be recompacted with the new embankment as hereinafter specified. Embankment shall be placed in layers not to exceed ten (10) inches uncompacted (loose) depth for the full width of the embankment, unless otherwise noted. Where embankment is adjacent to a hillside or old roadbed, the existing slope shall be cut in steps to not less than the vertical depth of an uncompacted layer. The fill material shall be placed from the low side and compacted. Each layer shall overlap the existing embankment by at least the width indicated by the embankment slope. Trees, stumps, roots, vegetation, debris or other unsuitable materials shall not be placed in embankment. Each layer of embankment shall be uniform as to material, density and moisture content before beginning compaction. Where layers of unlike materials abut each other, each layer shall be feather-edged for at least 100 feet or the material shall be so mixed as to prevent abrupt changes in the soil. No material placed in the embankment by dumping in a pile or windrow shall be incorporated in a layer in that position, but all such piles or windrows shall be moved by blading or similar methods. Clods or lumps of material shall be broken and the embankment material mixed by blading, harrowing, disking or similar methods to the end that a uniform material of uniform density is secured in each layer. Except as otherwise required by the drawings, all embankments shall be constructed in layers approximately parallel to the finished grade and each layer shall be so constructed as to provide a uniform slope of 1/4 inch per foot from the centerline of the embankment to the outside. Each layer shall be compacted to the required density and moisture by any method, type and size of equipment that will give the required compaction. Prior to and in conjunction with the rolling operation, each layer shall be brought to the moisture content necessary to obtain the required density and shall be kept leveled with suitable equipment to insure uniform compaction over the entire layer. For each layer of earth embankment and select material, it is the intent of this specification to provide the density as required herein, unless otherwise shown on the drawings. Soils for 022080 Page 1 of 2 Rev.10-30-2014 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 embankment shall be sprinkled with water as required to provide not less than optimum moisture and compacted to the extent necessary to provide not less than 95% Standard Proctor density (ASTM D698). Field density determinations will be made in accordance with approved methods. After each layer of earth embankment or select material is complete, tests, as necessary, will be made by the Engineer. If the material fails to meet the density specified, the course shall be reworked as necessary to obtain the specified compaction, and the compaction method shall be altered on subsequent work to obtain specified density. Such procedure shall be determined by, and subject to, the approval of the Engineer. The Engineer may order proof rolling to test the uniformity of compaction of the embankment layers. All irregularities, depressions, weak or soft spots which develop shall be corrected immediately by the Contractor. Should the embankment, due to any reason or cause, lose the required stability, density or moisture before the pavement structure is placed, it shall be recompacted and refinished at the sole expense of the Contractor. Excessive loss of moisture in the subgrade shall be prevented by sprinkling, sealing or covering with a subsequent layer of granular material. 3. SELECTION OF MATERIAL In addition to the requirement in the excavation items of the specifications covering the general selection and utilization of materials to improve the roadbed, embankments shall be constructed in proper sequence to receive the select material layers shown on drawings, with such modifications as may be directed by the Engineer. The layer of embankment inunediately preceding the upper layer of select material shall be constructed to the proper section and grade within a tolerance of not more than 0.10 foot from the established section and grade when properly compacted and finished to receive the select material layer. Select material, when specified, shall meet the requirements in City Standard Specification Section 022100 "Select Material". 4. MEASUREMENT AND PAYMENT Unless otherwise specified on the Bid Form, embankment shall not be measured and paid for separately,but shall be subsidiary to other items of work. 022080 Page 2 of 2 Rev.10-30-2014 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 SECTION 022100 SELECT MATERIAL 1.

CONSTRUCTION METHODS General - It is the primary requirement of this specification to secure a completed course of treated material containing a uniform time mixture, free from loose or segregated areas, of uniform density and moisture content, well bound for its full depth and with a smooth surface suitable for placing subsequent courses. It shall be the responsibility of the Contractor to regulate the sequence of his work, to use the proper amount of lime, maintain the work and rework the courses as necessary to meet the above requirements. Application - Lime shall be spread only on that area where the first mixing operations can be completed during the same working day. Unless otherwise shown on drawings, lime shall be applied at a rate in pounds of dry-hydrated lime per square yard, in the form of a slurry. Application rate may be varied by the Engineer, if conditions warrant, but no less than 6%must be applied. Certification of lime quantity and quality shall be provided as required to monitor the application. Certification should be in the form of weight tickets which indicate the actual weight of dry hydrated lime, CA(OH)2. The application and mixing of lime with the material shall be accomplished by the method hereinafter described. The lime shall be mixed with water in trucks with approved distributors and applied as a thin water suspension or slurry. Mixin - The mixing procedure shall be as hereinafter described. (a) First Mixing: The material and lime shall be thoroughly mixed by approved road mixers or other approved equipment, and the mixing continued until, in the opinion of the Engineer, a homogeneous, friable mixture of material and lime is obtained, free from all clods or lumps. Materials containing plastic clays or other material which will not readily mix with lime shall be mixed as thoroughly as possible at the time of the lime application, brought to the proper moisture content and left to cure 1 to 4 days as directed by the Engineer. During the curing period, the material shall be kept moist as directed. (b) Final Mixing: After the required curing time, the material shall be uniformly mixed by approved methods. If the soil binder-lime mixture contains clods, they shall be reduced in size by raking, blading, discing, harrowing, scarifying or the use of other approved pulverization methods. After mixing, the Engineer may sample the mixture at roadway moisture and test in accordance with TxDOT Tex-101-E (Part III) — Preparation of Soil and Flexible Base Material for Testing, to determine compliance with the gradation requirements in Table 1. 025210 Page 2 of 4 Rev.9-2-2020 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 Table 1 Gradation Re uirements (Minimum % Passing) Sieve Size Base Sub rade 1-3/4" 100 100 3/4" 85 85 #4 — 60 Old bituminous wearing surface shall be pulverized so that 100%will pass a 2 '/z" sieve. During the interval of time between applications and mixing, hydrated lime that has been exposed to the open air for a period of 6 hours or more, or to excessive loss due to washing or blowing, will not be accepted for payment. Compaction - Compaction of the mixture shall begin immediately after final mixing and in no case later than 3 calendar days after final mixing, unless approval is obtained from the Engineer. The material shall be aerated or sprinkled as necessary to provide the optimum moisture. Compaction shall begin at the bottom and shall continue until the entire depth of mixture is uniformly compacted as hereinafter specified. If the total thickness of the material to be treated cannot be mixed in one operation, the previously mixed material shall be bladed to a windrow just beyond the area to be treated and the next layer mixed with lime as previously specified. The first layer of the material shall be compacted in such a manner that the treated material will not be mixed with the underlying material. The course shall be sprinkled as required to maintain moisture content on the wet side of optimum and compacted to the extent necessary to provide the specified density. Unless shown otherwise on the drawings, all lime treated subgrades, sub-bases, and bases that are not in direct contact with surface or binder course shall be compacted to a minimum of 95% Standard Proctor density (AASHTO T99), unless otherwise specified. In addition to the requirements specified for density, the full depth of the material shown on the plans shall be compacted to the extent necessary to remain firm and stable under construction equipment. After each section is completed, tests, as necessary, will be made by the Engineer. If the material fails to meet the density requirements, it shall be reworked as necessary to meet these requirements. Rework, when required to meet pulverization requirements or density requirements, shall include the addition of lime, about 10% to 15% of the initial application rate, or as deemed necessary by the Engineer. A new optimum density will be obtained. Throughout this entire operation, the shape of the course shall be maintained by blading, and the surface, upon completion, shall be smooth and in conformity with the typical section shown on the drawings and to the established lines and grades. 025210 Page 3 of 4 Rev.9-2-2020 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 5.

Description. This Specification governs for the pre-qualification, testing, and field evaluation requirements for reflectorized pavement markers (RPMs). 4200.2. Units of Measurements. The values given in parentheses (if provided) are not standard and may not be exact mathematical conversions. Use each system of units separately. Combining values from the two systems may result in nonconformance with the standard. 4200.3. Material Producer List. The Materials and Pavements Section of the Construction Division (CST/M&P) maintains the Material Producer List (MPL) of all materials conforming to the requirements of this specification. Materials appearing on the MPL, entitled "Jiggle Bar Tiles, Pavement Markers, and Traffic Buttons,"require no further testing, unless deemed necessary by the Project Engineer or CST/M&P. 4200.4. Bidders' and Suppliers' Requirements. Before any material is allowed for use on Department projects, it must be of manufacture and product code or designation shown on the MPL. 4200.5. Pre-Qualification Procedure. The pre-qualification procedure consists of several steps, listed below, which are described in more detail in the following subsections: • Pre-qualification request, • Laboratory testing, • Field testing, • Provisional qualification, • Project evaluations, • Full qualification, • Periodic evaluation, • Disqualification, and • Re-Qualification. CST/M&P will provide notification at the completion of each step and will require confirmation from the supplier's contact person before proceeding to the next step. Costs of sampling and testing are normally borne by the Department; however, the costs to sample, test, and conduct field evaluations for materials failing to conform to the requirements of this specification are borne by the supplier. This cost will be assessed at the rate established by the Director of CST/1\4&P and in effect at the time of testing and will be billed directly to the Contractor or supplier.

NTPEP Testing. Submit NTPEP test data to CST/M&P for review if available. CST/M&P will acknowledge receipt of NTPEP data and will provide results of review within one month of receipt. The 12-month NTPEP test results for the pre-qualification of RPMs must meet the following: • all the requirements specified in ASTM D 4280 for the tests performed by NTPEP; • a retention rate equal or greater than 90 % of the placed RPMs (excluding the RPMs removed for testing); • a visual evaluation of 3 or greater, as defined by the most recent NTPEP Project Work Plan for Field Evaluations of Raised Pavement Markers and Marker Adhesives, for the marker case and marker lens for a minimum of 90 % of the placed RPMs (excluding the RPMs removed for testing); and • the minimum retroreflectivity values required after 12 months on the roadway listed in Table 1. 2. Application. Provide the name of the contractor, the traffic control plan, and the manufacturer and product code for the adhesive at least two weeks prior to the application for CST/M&P review and approval. CST/M&P will confirm the date and location of the field evaluation installation and resolve any problems as necessary. CST/M&P will provide between fifty and one hundred RPMs of each submitted type for application from the samples submitted for laboratory testing. Testing of submitted markers occurs concurrently with a set of control RPMs, for compliance with the requirements of this specification. Control markers are those RPMs currently listed on the MPL; if the MPL is reorganized and no marker exists to act as a control, an RPM that has undergone the most recent NTPEP testing on both asphalt and concrete will be used. Supplier is responsible for application of the RPMs in the presence of CST/M&P. Application must meet all Department specifications for RPM application and traffic control as well as the manufacturer's recommendations. Notify CST/M&P of any problems or concerns with the installation within one week of application and request a re-installation, if necessary. 3. Evaluation. CST/M&P will notify supplier of a suggested date for field testing evaluation at least one month prior to completion of the 12-month field trial. Provide the name of the contractor and traffic control plan for the evaluation at least 2 weeks prior to the scheduled evaluation date. Materials must meet the following requirements: a. Retention Rate. The retention rate of the test RPMs must be no less than 5% below that of the control RPMs. TEXAS DEPARTMENT OF TRANSPORTATION 3-7 EFFECTIVE DATE:JANUARY 2010 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 DEPARTMENTAL MATERIALS SPECIFICATION PAVEMENT MARKERS(REFLECTORizED) b. Body Damage. The test RPMs must not exhibit discoloration or body damage exceeding that of the control RPMs. They must not exhibit a repetitive form of damage or mode of failure (indicative of a design flaw) in a large percentage of the test RPMs. Body damage will be visually assessed according to NTPEP criteria. c.

They must be functional when viewed at a minimum distance of approximately 400 ft. in the daytime. A functional marker is both visible and conspicuous. d. Retroreflectivity. CST/M&P will remove twenty test RPMs from the pavement to undergo laboratory testing for retroreflectivity in accordance with Tex-842-B. Fifteen of the twenty RPMs pulled must pass the minimum reflective values shown in Table 1 (measured at 0.2° observation angle and 0° horizontal entrance angle). Table 1 Minimum Retroreflectivity(cd/fc)After 12 Months on the Roadway Face 12 Mo. Crystal 1.0 Amber 0.7 Red 0.2 D. Provisional Qualification. CST/M&P will grant provisional qualification after successful completion of the laboratory and field evaluations including NTPEP testing, when applicable. CST/M&P will send notification of provisional qualification, including the date of placement on the MPL, within one month after completion of the field evaluations. Failure to complete all project evaluation requirements successfully is grounds for cancellation of provisional qualification. E. Project Evaluation. Once the material is provisionally qualified and listed on the MPL, provide CST/M&P with project information for the first three jobs supplied with the RPMs and additional projects if requested. RPMs must meet the same performance criteria as for the field evaluation to receive full qualification. CST/M&P will return the project evaluation results after the 12-month evaluation of each project. 1. Full Qualification. CST/M&P will grant full pre-qualification and continue to list materials meeting all requirements of this specification on the MPL. Pre-qualification requires extensive field evaluations. It is critical that no significant changes are made to the RPMs' composition,manufacturing process, or design during or after pre-qualification without notifying CST/M&P. It is also critical that the RPMs provided be uniform, with minimum variations from marker to marker. Significant changes not reported by the manufacturer or variations in product, as determined by the Director of CST/M&P, may be cause for removal from the MPL.

To determine the heat stability flow, place 1000 g of adhesive in a loosely-covered quart can,heat to 218°C (425°F) and maintain at this temperature 4 hours before performing the flow test. B. Extraction and Abson Recovery. Use this procedure to separate and recover the base asphalt from the adhesive. Heat the adhesive just to the point where it will easily flow. Transfer between 125 and 150 g into a 1000-mL (1-qt.) Erlenmeyer flask containing 400 mL(13.5 fl. oz.) of trichloroethylene with a temperature of 52-66°C (125-150°F). Stir this mixture thoroughly to dissolve the asphalt. Decant the solvent-asphalt mixture. Recover the base asphalt from solvent according to Tex-211-F, but begin with the centrifuge step; the primary distillation is not necessary. Repeat the above extraction- recovery method as necessary to obtain the desired quantity of asphalt. C. Filler Separation Technique. Use this procedure to separate the filler material from the asphalt and determine the filler content of the adhesive. Weigh 10.00 10.01 g of solid adhesive,broken into small pieces, into a centrifuge flask with approximately 100 mL (3.5 fl. oz.)volume such as that specified in ASTM D 1796.

Place the sample flask in a balanced centrifuge and spin using a minimum relative centrifugal force of 150 (as determined in ASTM D 1796, Section 6.) Remove the sample flask and decant the solvent, taking care not to lose any solids. Repeatedly add more solvent, centrifuge, and decant until the solvent becomes clear and the filler appears free of asphalt. Dry the recovered filler at 71 ± 3°C (160± 5°F) to remove solvent. Weigh the dried filler. Filter the decanted solvent through a filter paper with a 20-25 µm retention factor to verify there is no loss of filler. Calculate the filler content as a percentage of the original sample weight. D. Filler Fineness. Use this procedure to determine the filler fineness. Use the same apparatus as described in ASTM C 430, except also use 75µm (No. 200) and 150 µm (No. 100) sieves. Prepare a water solution containing 1 wt. percent of a nonionic, water- soluble surfactant, such as Triton X-100,beforehand. Thoroughly wet the 1 g dry sample in the surfactant solution and allow it to soak for 30 min. Transfer the filler completely into the 45 µm (No. 325) sieve cup. Wash the sample with the water spray, as described in ASTM C 430, Section 5, for 2 min., adding surfactant solution as needed to disperse any clumped particles. Dry and weigh the sample and perform calculations as directed in ASTM C 430. Repeat the procedure using the other two sieve sizes. 6130.5. Acceptance. Bituminous adhesives are pre-qualified in accordance with Tex-538-C. Consult"Bituminous Marker Adhesive" for a list of materials currently pre-qualified under this procedure. 6130.6. Packaging and Labeling. Package the adhesive in self-releasing cardboard containers with essentially flat and parallel top and bottom surfaces such that the packages will stack properly. Each package must have a net weight of either 23 or 27 kg (50 or 60 lb.) and must weigh within 1 kg (2 lb.) of the stated quantity. Self-releasing cardboard dividers, which will separate each package into sections weighing no more than 7 kg (15 lb.) each, must be part of the packaging. Each package must display: • the manufacturer's name, • net weight, • lot or batch number, and • a product name that clearly identifies the material as either standard or flexible bituminous marker adhesive. 6130.7.

The limits shall not exceed three feet outside the footing on a vertical plane parallel to the footing except where specifically approved otherwise by the Engineer. The Contractor shall provide and install any sheeting, shoring, and bracing as necessary to provide a safe work area as required to protect workmen, structures, equipment,power poles, etc. The Contractor shall be responsible for the design and adequacy of all sheeting, shoring and bracing. The sheeting, shoring, and bracing shall be removed as the excavation is backfilled. Sloping Sides: In unimproved areas where sufficient space is available,the Contractor will be allowed to back slope the sides of the excavation. The back slope shall be such that the excavation will be safe from caving. Safety requirements shall govern the back slope used. De-watering: The Contractor shall keep the excavation free from water by use of cofferdams,bailing,pumping,well pointing, or any combination, as the particular situation may warrant. All de-watering devices shall be installed in such a manner as to provide clearance for construction, removal of forms, and inspection of exterior of form work. It is the intent of these specifications that the foundation be placed on a firm dry bed. The foundation bed shall be kept in a de-watered condition for a sufficient period of time to 027205 Page 3 of 6 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 insure the safety of the structure,but in no case shall de-watering be terminated sooner than seven(7)days after placing concrete. All de-watering methods and procedures are subject to the approval of the Engineer. The excavation shall be inspected and approved by the Engineer before work on the structure is started. The Contractor shall provide a relatively smooth,firm foundation bed for footings and slabs that bear directly on the undisturbed earth without additional cost to the City, regardless of the soil conditions encountered. The Engineer will be the sole judge as to whether these conditions have been met. The Contractor shall pile excavated material in a manner that will not create an unsafe condition. Unauthorized Over-Excavation: Excavation for slabs, footings, etc., that rest on earth, shall not be carried below the elevation shown on the drawings. In the event the excavation is carried below the indicated elevation, the Contractor shall bring the slab, footing, etc., to the required grade by filling with concrete. Wall Preparation for Pipe Penetrations: For sanitary sewer application,pipe penetrations for pipe sizes 4-inch through 15-inch shall be made with appropriately sized core drill bits recommended by the manufacturer.

Cuts are to be made using electric or gasoline powered circular saw with masonry blade. Impact type tools shall not be used. Handling: Manholes shall be handled and stored in a safe manner as necessary to prevent damaging either the manhole or the surroundings. If manhole must be moved by rolling,the ground which it traverses shall be smooth and free of rocks, debris, etc. Manholes shall be lifted as specified by the manufacturer. Height Adjustment: If necessary,utilize HDPE adjustment rings to adjust the manhole to the correct grade elevation. A maximum of 18" of adjustment rings may be utilized. Installation: Lower manhole into wet concrete until it rests at the proper elevation, and a minimum of six (6) inches into concrete, then plumb. Backfill Material: Unless shown otherwise on the drawings, initial backfill around manholes (from subgrade to five feet (5') above the top of the concrete footing) shall be flowable grout. The remaining final backfill around manholes shall be cement-stabilized sand, or approved equal, containing a minimum of 2 sacks of standard Type I or Type II Portland cement per cubic yard of sand, free of large hard lumps, rock fragments or other debris. The material shall be free of large lumps or clods which will not readily break down under compaction. This material shall be subject to approval by the Engineer. Backfill material shall be free of vegetation or other extraneous material. Topsoil should be stockpiled separately and used for finish grading around the structure, if necessary. 027205 Page 4 of 6 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 Schedule of Backfilling: The Contractor may begin backfilling around manhole as soon as the concrete has been allowed to cure and the forms removed. Compaction: Backfill shall be placed in layers not to exceed 6 inches compacted thickness and mechanically tamped to at least 95% Standard Proctor density(ASTM D698). Backfill shall be placed in such a manner as to prevent any wedging action against the structure. Contractor shall follow operational requirements for bypass pumping as set forth in City Standard Specification Section 027200 "Control of Wastewater Flows". 5. TESTING Manholes shall be tested for leakage by either of two tests as specified by the Engineer. Water Leakage Test: The Contractor shall provide water, labor, and materials for testing. Testing shall be as follows: 1. With sewers plugged, the manhole shall be filled with water. 2. The manhole shall be checked after 24 hours have elapsed. 3. Water loss shall not exceed 2.4 gallons per foot of depth for the 24-hour period for 4-foot diameter manholes, or 3.0 gallons per foot of depth for the 24-hour period for 5-foot diameter manholes. Water loss shall not exceed 0.6 gallon per foot of diameter per foot of depth for the 24-hour period for all sizes of sanitary manholes. 4. If the manhole is within 9 feet of a waterline that is not or cannot be encased, the manhole shall be tested for no leaks and no noticeable loss of water shall be experienced for the 24-hour period. If water loss is excessive,the Contractor shall correct the problem and the manhole shall be retested. Vacuum Test: Vacuum testing shall be in accordance with City Standard Specification Section 027203 "Vacuum Testing of Wastewater Manholes and Structures". 6. GRADE ADJUSTMENT OF EXISTING FIBERGLASS MANHOLES The adjustment of the ring and cover is to be achieved by removal or addition of HDPE grade adjustment rings that rest above the fiberglass corbel. If the ring and cover must be lowered to the extent that the new elevation cannot be achieved by removal of adjustment rings and it is necessary to remove a section of the fiberglass manhole, this work shall be done as described below. Note that manhole repair kits are available for this work. Remove the appropriately sized section of the existing manhole from the vertical manhole wall at least 6 inches below the seam where the corbel meets the vertical wall. 027205 Page 5 of 6 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 Excavate evenly around the manhole as required.

CONSTRUCTION METHODS Reinforced concrete pipe culverts shall be constructed from the specified materials in accordance with the following methods and procedures: 1. Excavation. All excavation shall be in accordance with the requirements of City Standard Specification Section 022020 "Excavation and Backfill for Utilities," except where tunneling or jacking methods are shown on the plans or permitted by the Engineer. When pipe is laid in a trench, the trench, when completed and shaped to receive the pipe, shall be of sufficient width to provide free working space for satisfactory bedding and jointing and thorough tamping of the backfill and bedding material under and around the pipe. The Contractor shall make such temporary provisions as may be necessary to insure adequate drainage of the trench and bedding during the construction operation. Pipe shall be placed such that the identification markings are visible at the top prior to backfill. 2. Bedding. The pipe shall be bedded in accordance with the bedding details shown on the drawings. Bedding shall not be measured for pay,but shall be subsidiary to other work. If the subgrade of the trench is unstable, even if this condition occurs at relatively shallow depths, full encasement of the pipe with crushed stone shall be required. 3. Lang Pipe. Unless otherwise authorized by the Engineer, the laying of pipe on the prepared foundation shall be started at the outlet (downstream) end with the spigot or tongue end pointing downstream, and shall proceed toward the inlet(upstream) end with the abutting sections properly matched, true to the established lines and grades. Where bell and spigot pipe are used, cross trenches shall be cut in the foundation to allow the barrel of the pipe to rest firmly upon the prepared bed. These cross trenches shall be not more than two inches larger than the bell ends of the pipe. Proper facilities shall be provided for hoisting and lowering the sections of pipe into the trench without disturbing the prepared foundation and the sides of the trench. The ends of the pipe shall be carefully cleaned before the pipe is placed. As each length of pipe is laid, the mouth of the pipe shall be protected to prevent the entrance of earth or bedding material. The pipe shall be fitted and matched so that when laid in the bed, it shall form a smooth, uniform conduit. When elliptical pipe with circular reinforcing or circular pipe with elliptical reinforcing is used, the pipe shall be laid in the trench in such position that the markings "TOP" or "BOTTOM" shall not be more than 5 degrees from the vertical plane through the longitudinal axis of the pipe. For pipe over 42 inches in diameter, the Contractor may drill two holes not larger than 2 inches in diameter, in the top of each section of the pipe, to aid in lifting and placing. The holes shall be neatly drilled, without spalling of the concrete, and shall be done without the cutting of any reinforcement. After the pipe is laid, the holes shall be filled with mortar and properly cured, and placed such that they are visible from the top for inspection prior to backfill. Multiple installations of reinforced concrete pipe shall be laid with the center lines of 027402 Page 4of7 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 individual barrels parallel. When not otherwise indicated on plans, the following clear distances between outer surfaces of adjacent pipe shall be used. Diameter of Pipe 18" 24" 30" 36" 42" 48" 54" 60"to 84" Clear Distance Between Pipes 0'-9" 0'-11" 1'-1" 1'-3" 1'-5" 1'-7" 1'-11" 2'-0" 4. Jointing. a. If the use of Portland cement mortar joints is allowed, all pipe shall be jointed tight and sealed with stiff mortar, composed of one part Portland cement and two parts sand, so placed as to form a durable water-tight joint. The installation shall be as required by the Engineer. b. Joints using Rubber Gaskets: Where rubber gasket pipe joints are required by the plans, the joint assembly shall be made according to the recommendations of the gasket manufacturer. Water-tight joints will be required when using rubber gaskets. c. Joints using Cold-Applied Preformed Plastic Gaskets shall be made as follows: A suitable prime of the type recommended by the manufacturer of the gasket joint sealer shall be brush-applied to the tongue and groove joint surfaces and the end surfaces and allowed to dry and harden. No primer shall be applied over mud, sand or dirt or sharp cement protrusions. The surface to be primed must be clean and dry when primer is applied. Before laying the pipe in the trench, the plastic gasket sealer shall be attached around the tapered tongue or tapered groove near the shoulder or hub of each pipe joint. The paper wrapper shall be removed from one side only of the two-piece wrapper on the gasket and pressed firmly to the clean, dry pipe joint surface. The outside wrapper shall not be removed until immediately before pushing the pipe into its final position. When the tongue is correctly aligned with the flare of the groove, the outside wrapper on the gasket shall be removed and the pipe shall be pulled or pushed home with sufficient force and power (backhoe shovel, chain hoist, ratchet hoist or winch) to cause the evidence of squeeze-out of the gasket material on the inside or outside around the complete pipe joint circumference. The extruded gasket material shall be smoothed out over the joint on the exterior and interior of the pipe. Any joint material pushed out into the interior of the pipe that would tend to obstruct the flow shall be removed. (Pipe shall be pulled home in a straight line with all parts of the pipe on line and grade at all times.) Backfilling of pipe laid with plastic gasket joints may proceed as soon as the joint has been inspected and approved by the Engineer. Special precautions shall be taken in placing and compacting backfill to 027402 Page 5 of 7 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 avoid damage to the joints. When the atmospheric temperature is below 60 degrees F, plastic joint seal gaskets shall either be stored in an area warmed to above 70 degrees F, or artificially warmed to this temperature in a manner satisfactory to the Engineer. Gaskets shall then be applied to pipe joints immediately prior to placing pipe in the trench, followed by connection to previously laid pipe. d. Pipe Joints for storm sewers shall be wrapped with geotextile material. The geotextile wrap shall be at least 2 feet wide and shall be centered on each joint. 5. After the pipe has been placed, bedded and jointed as specified, filling and/or backfilling shall be done in accordance with the applicable requirements of City Standard Specification Section 022020 "Excavation and Backfill for Utilities." If unstable conditions are encountered, fully encase the pipe with crushed stone as described above. When mortar joints are allowed, no fill or backfill shall be placed until the jointing material has been cured for at least six (6)hours. Special precautions shall be taken in placing and compacting the backfill to avoid any movement of the pipe or damage to the joints. For side drain culverts and all other culverts where joints consist of materials other than mortar, immediate backfilling will be permitted. 6. Unless otherwise shown on the plans or permitted in writing by the Engineer, no heavy earth moving equipment will be permitted to haul over the structure until a minimum of 4 feet of permanent or temporary compacted fill has been placed thereon. Pipe damaged by the Contractor's equipment shall be removed and replaced by the Contractor at no additional cost. 7. Cleaning and Television Inspection. All enclosed reinforced concrete pipe and manholes installed on this project shall be cleaned and televised in accordance with City Standard Specification Section 027611 "Cleaning and Televised Inspection of Conduits." 4. MEASUREMENT Unless otherwise specified on the Bid Form, reinforced concrete pipe will be measured by the linear foot. Such measurement will be made between the ends of the pipe barrel along its central axis. Where spurs or branches, or connections to existing pipe lines are involved, measurement of the spur or new connecting pipe will be made from the intersection of its center axis with the outside surfaces of the pipe into which it connects. Where inlets, headwalls, catch basins, manholes,junction chambers, or other structures are included in lines of pipe, that length of pipe tying into the structure wall will be included for measurement but no other portion of the structure length or width will be so included. For multiple pipes, the measured length will be the sum of the lengths of the barrels measured as prescribed above. 027402 Page 6 of 7 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 5. PAYMENT Payment for reinforced concrete pipe measured as prescribed above will be made at the contract unit price bid per linear foot for the various sizes of 'Reinforced Concrete Pipe" of the class specified. Payment shall be full compensation for furnishing and transporting the pipe; hauling and placing of earth cushion material where required for bedding pipe; for the preparation and shaping of beds; for hauling, placing and jointing of pipes; for furnishing and installing geotextile pipe joint wrapping; for end finish; for all connections to existing and new structures; for cleaning and television inspection; and for all other items of materials, labor, equipment, tools, excavation, backfill and incidentals necessary to complete the culvert or storm sewer in accordance with the plans and these specifications. 027402 Page 7 of 7 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 SECTION 027404 CONCRETE BOX CULVERTS 1.

SCOPE This specification shall govern for all work, equipment, supervision and materials required to provide for cleaning and remote CCTV inspection and documentation of wastewater or other lines and manholes as required. 2. TECHNICAL REQUIREMENTS 2.1 General Closed circuit television inspection will typically be done under one or more of the conditions listed below. Requirements for on-screen labeling during each line segment set up, televising, video file labeling and hard copy inspection reports will be specifically addressed. The Contractor shall neither request nor receive assistance from the City, in the performance of work described in this specification. Unless otherwise specified and at Contractors expense, the Contractor shall provide for the control of wastewater flows and monitoring of the collection system for back-ups and surcharges, while flow control devices are in place. It shall be the responsibility of the Contractor(s) to adhere to all applicable OSHA rules and regulations while performing any and all City-related projects or jobs (to include,but not necessarily limited to "Confined Space Entry". 2.2 Inspection Equipment and Methods Electronic media shall be used to record the condition of all the segments of the mains and the manholes, tap locations and unusual situations during inspection. The inspection imaging shall be made on color professional grade DVD format for each line segment. All observations will require both audio and on-screen display. The camera shall transit through the wastewater line in either direction at a speed not greater than 30 feet per minute, stopping as necessary to permit proper documentation of the wastewater line's condition. Lighting for the camera shall be suitable to allow a clear picture of the entire periphery of the pipe. A television camera with pan and tilt capability will be required. The camera, television monitor, and other components of the video systems shall be capable of producing picture quality to the satisfaction of the City. The capture system shall have the capability of recording, digitizing and storing single frames of video images and "real time" live video, as well as collecting, storing and printing wastewater line inspection data for graphic display and report generation. The imaging capture system shall store digitized picture images, have the ability to export picture files to industry standard formats Opg, bmp, and tif), be transferable to DVD and be printed at no cost to the City. Use of proprietary software is discouraged; however, if the Contractor provides the software and 027611 Page 1 of 8 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 three licenses to the City, proprietary software COMPATIBLE with the City's GIS and existing database systems in use may be approved. However, in every case all observations will be recorded using the City approved PACP codes. 2.3 Flow Control /By-Passim This procedure will be used on all previously accepted (City owned) line segments. Except for new wastewater line acceptance inspections, the line shall be dewatered during inspection. A water jet cleaning unit will normally be running in the line in advance of the television camera to allow the highest quality picture available. Dewatering shall remove standing water and fog from the line segment to provide 360 degree view of the pipe being televised. Too high water level or the camera being submerged will be grounds for rejection of the inspection. All wastewater flows from intersecting lines shall typically be controlled through the use of in-line plugs for vacuum trucks and are considered subsidiary to the inspection for all line sizes. Plugs in intersecting lines shall be installed by the Contractor with no assistance from the City. The Contractor shall also monitor the upstream system for back-ups and surcharges, which may lead to Sanitary Sewer Overflows (SSOs). The Contractor shall immediately report to the City Call Center (361) 826-2489 all sanitary sewer overflows. Flow Control devices shall be installed in accordance with all applicable OSHA requirements, including, but not necessarily limited to confined space protocol. 2.4 Evaluation of Existing Lines for Potential Repairs/Rehabilitation—Pre CCTV: Cleaning and televising using a CCTV camera may be needed to traverse each line segment from manhole to manhole as specified in the work order. When an obstruction prevents the camera from proceeding, the obstruction will be recorded on the initial setup and a reverse setup will be attempted to view the pipe and obstruction from the other side. If the camera fails to pass through the entire section, the inspection shall be considered complete and no additional inspection will be required. However, the line segment evaluation form, as well as the graphic report, shall note full line length and the length traveled from each manhole set-up. All inspection efforts on the line segment will be recorded on the same tape / disk. The Contractor must exert all reasonable effort to televise the entire length of a segment of wastewater line, or to assist the repair crews with usable information for point repair. Prior to transiting the line the video display initially is to include upstream and downstream manhole numbers, pipe size / material, adjacent street names and the date. During the transit the display must show the continuous distance from the insertion manhole with an accuracy of +1% of the actual length to help mark observations on the report form. The video must have narrative documentation of notable observations. The Inspection Report shall consist of condition observations recorded using City-approved computer software generated formats, generally conforming to NASSCO and PACP codes. Specifically, items considered notable include: deviations in alignment and grade; abnormal conditions of the pipe barrel and joints; locations 027611 Page 2 of 8 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 and quantities of any sources of infiltration or inflow; dropped, broken, properly/ improperly installed service taps; debris, roots or other impediments to flow and any other condition that may prevent either the proper completion of the inspection, or affect any proposed rehabilitation process. Evaluation of existing lines includes associated manhole inspection. 2.5 Evaluation After Repairs /Rehabilitation Post CCTV: Following repairs or rehabilitation to existing lines (by Contractor), a CCTV camera shall travel through required line segment to televise. The intent of this process is to inspect the interior of the line to determine the location of repairs, and extent of any unacceptable work. Prior to transiting the line the video display initially is to include upstream and downstream manhole numbers, pipe size / material, adjacent street names and the date. During the transit the display must show the continuous distance from the insertion manhole with an accuracy of+/- 1% of the actual length to help mark observations on the report form. Specifically, items such as detailed inspection of the repaired area using pan-and- tilt equipment will be shown in the Inspection Report, including digital photographs of acceptable or inadequate and/or questionable work. The video must include narrative documentation of notable observations, and be cross referenced to the Inspection Report. The Inspection Report shall consist of condition observations recorded using City-approved computer-software generated formats conforming to NASSCO and PACP codes. 2.6 New Pipeline Inspection: Upon completion of the installation of new lines, including any appurtenances such as manholes, service connections, etc., a CCTV camera shall traverse through each completed line segment. The intent of this process is to inspect the interior of the completed line to determine the location of service taps and extent of omissions and/or any unacceptable work on the pipeline or manholes, such as sags, infiltration, gapped joints, protruding gaskets, etc. Prior to transiting the line, the initial video shall initially include the upstream and downstream manhole designations, pipe size, project name and other pertinent information. When inspecting / documenting new wastewater line conditions, the Contractor must conduct a specific inspection for the presence of sags in the newly installed line. The approved method involves the use of an inclinometer on the camera. The belly tolerance is 5% or less for acceptable pipe installation. Any deviation from the 5% belly tolerance limit must be approved by the applicable Utility Operating Department. The graphic report will note the start and stop of sags and approximate maximum depth. During the transit the display must show the continuous distance from the insertion manhole with an accuracy of +1% of the actual length to help mark observations on the Inspection Report form. The video must include narrative documentation of notable observations, and be cross referenced to the Inspection 027611 Page 3 of 8 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 Report. The Inspection Report shall consist of condition observations recorded using approved computer-software generated formats. Specifically, items such as deviations in alignment and grade causing bellies / sags; abnormal conditions of the pipe barrel and joints; locations and quantities of any sources of infiltration or inflow; dropped, broken, properly/ improperly installed service taps or any other condition that may assist the Utilities Department in determining the quality of the pipeline installation. 2.7 Manhole Inspection: A CCTV camera shall traverse the manhole from top to bottom to record the condition of the manhole and invert for structural condition and sources of infiltration on the manhole and invert. The initial video display must show the entry manhole number, location/ street address, date and depth. a. The requirement is to commence capturing video at ground level. The video must be steady while panning and lowering to clearly record condition of the ring, corbel, the walls, and pipeline penetrations. The camera is to rotate during descent to inspect typical conditions and all penetrations. At the bottom of the manhole the complete invert will be inspected / viewed for infiltration and general condition. A washed out picture due to sunlight or shaking will be rejected for payment b. This manhole information may be retained on the same DVD if the line segment is also being investigated, or, if inspection is issued as a separate work order, a separate DVD and report will be required. As with pipeline inspection, digital photographs of key points of note must accompany the report and DVD. These would include seals on pipeline penetration, infiltration locations and other anomalies. c. The format of the Manhole Inspection Report will be as proposed by the Contractor and, following discussion, mutually approved by the Utilities Department and the Contractor. A sample form is included at the end of this specification. It will contain as a minimum: location& I.D.number manhole diameter manhole material depth of manhole condition of ring/ cover evidence of infiltration condition of walls presence of inflow inhibitor condition of pipe mouths presence of coatings condition of invert location: street/ easement above invert penetrations 2.8 CCTV Set-up: a. A CCTV set-up includes all of the work, equipment, supervision,personnel, and materials needed to traverse a line segment. 027611 Page 4 of 8 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 2.9 CCTV Reverse Sq-u .

(7) Admixtures Calcium Chloride will not be permitted. Unless otherwise noted, air-entraining, retarding and water-reducing admixtures may be used in all concrete and shall conform to the following requirements: A "water-reducing, retarding admixture" is defined as a material which, when added to a concrete mixture in the correct quantity, will reduce the quantity of mixing water required to produce concrete of a given consistency and will retard the initial set of the concrete. A "water-reducing admixture" is defined as a material which, when added to a concrete mixture in the correct quantity, will reduce the quantity of mixing water required to produce concrete of a 030020 Page 4 of 13 Rev.10-30-2014 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 given consistency. (a) Retarding and Water-Reducing Admixtures. The admixture shall meet the requirements for Type A and Type D admixture as specified in ASTM Designation: C494,modified as follows: (1) The water-reducing retarder shall retard the initial set of the concrete a minimum of 2 hours and a maximum of 4 hours, at a specified dosage rate, at a temperature of 90°F. (2) The cement used in any series of tests shall be either the cement proposed for specific work or a "reference" Type I cement from one mill. (3) Unless otherwise noted on the plans, the minimum relative durability factor shall be 80. The air-entraining admixture used in the referenced and test concrete shall be neutralized Vinsol resin. (b) Air-Entraining Admixture. The admixture shall meet the requirements of ASTM Designation: C260, modified as follows: (1) The cement used in any series of tests shall be either the cement proposed for specific work or a "reference" Type I cement from one mill. (2) Unless otherwise noted on the plans, the minimum relative durability factor shall be 80. The air-entraining admixture used in the referenced concrete shall be neutralized Vinsol resin. 3. STORAGE OF CEMENT All cement shall be stored in well-ventilated weatherproof buildings or approved bins, which will protect it from dampness or absorption of moisture. Storage facilities shall be ample, and each shipment of packaged cement shall be kept separated to provide easy access for identification and inspection. The Engineer may permit small quantities of sacked cement to be stored in the open for a maximum of 48 hours on a raised platform and under waterproof covering. 4. STORAGE OF AGGREGATE The method of handling and storing concrete aggregate shall prevent contamination with foreign materials. If the aggregates are stored on the ground, the sites for the stockpiles shall be clear of all vegetation and level. The bottom layer of aggregate shall not be disturbed or used without recleaning. 030020 Page 5 of 13 Rev.10-30-2014 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 When conditions require the use of two or more sizes of aggregates, they shall be separated to prevent intermixing. Where space is limited, stockpiles shall be separated by physical barriers. Methods of handling aggregates during stockpiling and subsequent use shall be such that segregation will be minimized. Unless otherwise authorized by the Engineer, all aggregate shall be stockpiled at least 24 hours to reduce the free moisture content. 5. MEASUREMENT OF MATERIALS The measurement of the materials, except water, used in batches of concrete, shall be by weight. The fine aggregate, coarse aggregate and mineral filler shall be weighed separately. Where bulk cement is used, it shall be weighed separately, but batch weighing of sacked cement will not be required. Where sacked cement is used, the quantities of material per batch shall be based upon using full bags of cement. Batches involving the use of fractional bags will not be permitted. Allowance shall be made for the water content in the aggregates. Bags of cement varying more than 3 percent from the specified weight of 94 pounds may be rejected, and when the average weight per bag in any shipment, as determined by weighing 50 bags taken at random, is less than the net weight specified, the entire shipment may be rejected. If the shipment is accepted, the Engineer will adjust the concrete mix to a net weight per bag fixed by an average of all individual weights which are less than the average weight determined from the total number weighed. 6. CLASSIFICATION AND MIX DESIGN It shall be the responsibility of the Contractor to furnish the mix design, using a coarse aggregate factor acceptable to the Engineer, for the class(es) of concrete specified. The mix shall be designed by a qualified concrete technician to conform with the requirements contained herein and in accordance with the THD Bulletin C-11. The Contractor shall perform, at his own expense, the work required to substantiate the design, except the testing of strength specimens, which will be done by the Engineer. Complete concrete design data shall be submitted to the Engineer for approval. It shall also be the responsibility of the Contractor to determine and measure the batch quantity of each ingredient, including all water, so that the mix conforms to these specifications and any other requirements shown on the plans. Trial batches will be made and tested using all of the proposed ingredients prior to placing the concrete, and when the aggregate and/or brand of cement or admixture is changed. Trial batches shall be made in the mixer to be used on the job. When transit mix concrete is to be used, the trial designs will be made in a transit mixer representative of the mixers to be used. Batch size shall not be less than 50 percent of the rated mixing capacity of the truck. Mix designs from previous or concurrent jobs may be used without trial batches if it is shown that 030020 Page 6 of 13 Rev.10-30-2014 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 no substantial change in any of the proposed ingredients has been made. The coarse aggregate factor shall not be more than 0.82, except that when the voids in the coarse aggregate exceed 48 percent of the total dry loose volume, the coarse aggregate factor shall not exceed 0.85. The coarse aggregate factor shall not be less than 0.70 for Grades 1, 2 and 3 aggregates. If the strength required for the class of concrete being produced is not secured with the cement specified in Table 4, the Contractor may use an approved water-reducing or retarding admixture, or he shall furnish aggregates with different characteristics which will produce the required results. Additional cement may be required or permitted as a temporary measure until the redesign is checked. Water-reducing or retarding agents may be used with all classes of concrete at the option of the Contractor. When water-reducing or retarding agents are used at the option of the Contractor, reduced dosage of the admixture will be permitted. Entrained air will be required in accordance with Table 4. The concrete shall be designed to entrain 5 percent air when Grade 2 coarse aggregate is used and 6 percent when Grade 3 coarse aggregate is used. Concrete as placed in the structure shall contain the proper amount as required above with a tolerance of plus or minus 1.5 percentage points. Occasional variations beyond this tolerance will not be cause for rejection. When the quantity of entrained air is found to be above 7 percent with Grade 2 coarse aggregate or above 8 percent for Grade 3 coarse aggregate, additional test beams or cylinders will be made. If these beams or cylinders pass the minimum flexural or compressive requirements, the concrete will not be rejected because of the variation in air content. 7. CONSISTENCY In cases where the consistency requirements cannot be satisfied without exceeding the maximum allowable amount of water, the Contractor may use, or the Engineer may require, an approved water-reducing or retarding agent, or the Contractor shall furnish additional aggregates or aggregates with different characteristics, which will produce the required results. Additional cement may be required or permitted as a temporary measure until aggregates are changed and designs checked with the different aggregates or admixture. The consistency of the concrete as placed should allow the completion of all finishing operations without the addition of water to the surface. When field conditions are such that additional moisture is needed for the final concrete surface finishing operation, the required water shall be applied to the surface by fog spray only, and shall be held to a minimum. The concrete shall be workable, cohesive, possess satisfactory finishing qualities, and of the stiffest consistency that can be placed and vibrated into a homogenous mass. Excessive bleeding shall be avoided. Slump requirements will be as specified in Table 3. 030020 Page 7 of 13 Rev.10-30-2014 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 TABLE 3 Slump Requirements Concrete Designation Desired Slump Max.

QUALITY OF CONCRETE General The concrete shall be uniform and workable. The cement content, maximum allowable water- cement ratio, the desired and maximum slump and the strength requirements of the various classes of concrete shall conform to the requirements of Table 3 and Table 4 and as required herein. During the process of the work, the Engineer or his designated representative will cast test cylinders or beams as a check on the compressive or flexural strength of the concrete actually placed. Test cylinders must be picked up by the testing lab within 24 hours. A test shall be defined as the average of the breaking strength of two cylinders or two beams, as the case may be. Specimens will be tested in accordance with TxDOT Test Methods Tex-418-A or Tex-420-A. Test beams or cylinders will be required as specified in the contract documents. For small placements on structures such as manholes, inlets, culverts, wingwalls, etc., the Engineer may vary the number of tests to a minimum of one for each 25 cubic yards placed over a several day period. All test specimens, beams or cylinders, representing tests for removal of forms and/or falsework shall be cured using the same methods, and under the same conditions as the concrete represented. "Design Strength"beams and cylinders shall be cured in accordance with THD Bulletin C-11. The Contractor shall provide and maintain curing facilities as described in THD Bulletin C-11 for the purpose of curing test specimens. Provision shall be made to maintain the water in the curing tank at temperatures between 70°F and 90°F. When control of concrete quality is by twenty-eight-day compressive tests, job control will be by seven-day compressive tests which are shown to provide the required twenty-eight-day strength, based on results from trial batches. If the required seven-day strength is not secured with the 030020 Page 8 of 13 Rev.10-30-2014 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 cement specified in Table 4, changes in the batch design will be made.

Any concrete which is not in place within the limits outlined in City Standard Specification Section 038000 "Concrete Structures", Article "Placing Concrete-General", shall not be used. Retamping of concrete will not be permitted. In threatening weather, which may result in conditions that will adversely affect the quality of the concrete to be placed, the Engineer may order postponement of the work. Where work has been started and changes in weather conditions require protective measures, the Contractor shall furnish adequate shelter to protect the concrete against damage from rainfall, or from freezing temperatures. If necessary to continue operations during rainfall, the Contractor shall also provide protective coverings for the material stockpiles. Aggregate stockpiles need be covered only to the extent necessary to control the moisture conditions in the aggregates to adequately control the consistency of the concrete. 10. MIXING AND MIXING EQUIPMENT All equipment, tools, and machinery used for hauling materials and perfonning any part of the work shall be maintained in such condition to insure completion of the work underway without excessive delays for repairs or replacements. The mixing shall be done in a batch mixer of approved type and size that will produce uniform 030020 Page 9 of 13 Rev.10-30-2014 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 distribution of the material throughout the mass. Mixers may be either the revolving drum type or the revolving blade type, and shall be capable of producing concrete meeting the requirements of these specifications.

The compound shall produce a firm,continuous,uniform moisture impermeable film free from pinholes and shall adhere satisfactorily to the surfaces of damp concrete. It shall,when applied to the damp concrete surface at the rate of coverage specified herein,be dry to the touch in not more than 4 hours, and shall adhere in a tenacious film without running off or appreciable sagging. It shall not disintegrate, check, peel or crack during the required curing period. The compound shall not peel or pick up under traffic and shall disappear from the surface of the concrete by gradual disintegration. The compound shall be delivered to the job only in the manufacturer's original containers, which shall be clearly labeled with the manufacturer's name, the trade name of the material, and a batch number or symbol with which test samples may be correlated. The water retention test shall be in accordance with TxDOT Test Method Tex-219-F. Percentage loss shall be defined as the water lost after the application of the curing material was applied. The permissible percentage moisture loss (at the rate of coverage specified herein) shall not exceed the 038000 Page 3 of 19 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 following: 24 hours after application............2 percent 72 hours after application............4 percent Type 1 (Resin Base Only)curing compound will be permitted for slab concrete in bridge decks and top slabs of direct traffic culverts. (b) Mat curing of concrete is allowed where permitted by Table 1 in this specification or where otherwise approved by the Engineer. 3. EXPANSION JOINTS Joints and devices to provide for expansion and contraction shall be constructed where and as indicated herein or on the plans. All open j oints and joints to be filled with expansion joint material, shall be constructed using forms adaptable to loosening or early removal. To avoid expansion or contraction damage to the adjacent concrete, these forms shall be loosened as soon as possible after final concrete set to permit free movement without requiring full form removal. Prior to placing the sealing material, the vertical facing the joint shall be cleaned of all laitance by sandblasting or by mechanical routing. Cracked or spalled edges shall be repaired. The j oint shallbe blown clean of all foreign material and sealed. Where preformed fiber joint material is used,it shall be anchored to the concrete on one side of the joint by light wire or nails, to prevent the material from falling out. The top one inch (1") of the joint shall be filled with joint sealing material. Finished joints shall conform to the indicated outline with the concrete sections completely separated by the specified opening or joint material. Soon after form removal and again where necessary after surface finishing, all projecting concrete shall be removed along exposed edges to secure full effectiveness of the expansion joints. 4. CONSTRUCTION JOINTS The j oint formed by placing plastic concrete in direct contact with concrete that has attained its initial set shall be deemed a construction joint. The term "monolithic placement" shall be interpreted to mean at the manner and sequence of concrete placing shall not create construction joints. Construction joints shall be of the type and at the locations shown on the plans. Additional joints will not be permitted without written authorization from the Engineer, and when authorized, shall have details equivalent to those shown on the plans for joints in similar locations. Unless otherwise provided, construction joints shall be square and normal to the forms. Bulkheads shall be provided in the forms for all joints, except when horizontal. Construction joints requiring the use of joint sealing material shall be as detailed on the plans. The 038000 Page 4 of 19 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 material will be specified on the plans without referenced to joint type. A concrete placement terminating at a horizontal construction joint shall have the top surface roughened thoroughly as soon as practicable after initial set is attained. The surfaces at bulkheads shall be roughened as soon as the forms are removed. The hardened concrete surface shall be thoroughly cleaned of all loose material, laitance, dirt or foreign material, and saturated with water so it is moist when placing fresh concrete against it. Forms shall be drawn tight against the placing of the fresh concrete. 5. FORMS (1) General. Except where otherwise specified, forms may be of either timber or metal. Forms for round columns exposed to view shall be of steel, except that other materials will be allowed with written permission of the Engineer. Forming plans shall be submitted to the Engineer for approval as specified. Forms shall be designed for the pressure exerted by a liquid weighing 150 pounds per cubic foot. The rate of placing the concrete shall be taken into consideration in determining the depth of the equivalent liquid. For j ob fabricated forms,an additional live load of 50 pounds per square foot shall be allowed on horizontal surfaces. The maximum unit stresses shall not exceed 125 percent of the allowable stresses used by the Texas Department of Transportation for the design of structures. Commercially produced structural units used in formwork shall not exceed the manufacturer's maximum allowable working load for moment, shear or end reaction. The maximum working load shall include a live load of 35 pounds per square foot of horizontal form surface, and sufficient details and data shall be submitted for use in checking formwork details for approval. Forms shall be practically mortar-tight,rigidly braced and strong enough to prevent bulging between supports, and maintained to the proper line and grade during concrete placement. Forms shall be maintained in a manner that will prevent warping and shrinkage. Offset at form joints shall not exceed one-sixteenth of an inch(1/16"). Deflections due to cast-in-place slab concrete and railing shown in the dead load deflection diagram shall be taken into account in the setting of slab forms. All forms and footing areas shall be cleaned of any extraneous matter before placing concrete. Permission to place concrete will not be given until all such work is completed to the satisfaction of the Engineer. If, at any stage of the work, the forms show signs of bulging or sagging,the portion of the concrete causing such condition shall be removed immediately,if necessary, and the forms shall be reset and securely braced against further movement. 038000 Page 5 of 19 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 (2) Timber Forms. Lumber for forms shall be properly seasoned, of good quality, and free from imperfections which would affect its strength or impair the finished surface of the concrete. The lumber used for facing or sheathing shall be finished on at least one side and two edges and shall be sized to uniform thickness. Form lining will be required for all formed surfaces, except for the inside of culvert barrels, inlets and manholes; surfaces that are subsequently covered by backfill material or are completely enclosed; and, any surface formed by a single finished board. Lining will not be required when plywood forms are used. Form lining shall be of an approved type such as Masonite or plywood. Thin membrane sheeting, such as polyethylene sheets, shall not be used for form lining. Forms may be constructed of plywood not less than one-half inch in thickness,with no form lining required. The grain of the face plies on plywood forms shall be placed parallel to the span between the supporting studs or joists. Plywood used for forming surfaces that remain exposed shall be equal to that specified as B-B Plyform Class I or Class II Exterior, of the U. S. Department of Commerce, National Bureau of Standards and Technology, latest edition. Forms or form lumber to be reused shall be maintained clean and in good condition. Any lumber which is split, warped, bulged, marred, or has defects that will produce inferior work, shall not be used and, if condemned, shall be promptly removed from the work. Studs and joists shall be spaced so that the facing form material remains in true alignment under the imposed loads. Wales shall be spaced close enough to hold forms securely to the designated lines and scabbed at least 4 feet on each side of joints to provide continuity. A row of wales shall be placed near the bottom of each placement. Facing material shall be placed with parallel and square joints and securely fastened to supporting studs. Forms for surfaces receiving only an ordinary finish and exposed to view shall be placed with the form panels symmetrical, i.e., long dimensions set in the same direction. Horizontal joints shall be continuous. Molding specified for chamfer strips or other uses shall be made of materials of a grade that will not split when nailed and which can be maintained to a true line without warping. Wood molding shall be mill cut and dressed on all faces. Unless otherwise provided, forins shall be filleted at all sharp corners and edges with triangular chainfer strips measuring three-quarter inch (3/4") on the sides. Forms for railing and ornamental work shall be constructed to standards equivalent to first-class millwork. All moldings,panel work and bevel strips shall be straight and true with nearly mitered joints designed so the finished work is true, sharp and clean cut. 038000 Page 6 of 19 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 All forms shall be constructed to permit their removal without marring or damaging the concrete. The forms may be given a slight draft to permit ease of removal. Metal form ties of an approved type or a satisfactory substitute shall be used to hold forms in place and shall be of a type that permits ease of removal of the metal as hereinafter specified. All metal appliances used inside of forms for alignment purposes shall be removed to a depth of at least one-half inch (1/2") from the concrete surface. They shall be made so the metal may be removed without undue chipping or spalling,and when removed,shall leave a smooth opening in the concrete surface. Burning off of rods, bolts or ties will not be permitted. Any wire ties used shall be cut back at least one-half inch (1/2") from the face of the concrete. Devices holding metal ties in place shall be capable of developing the strength of the tie and adjustable to allow for proper alignment. Metal and wooden spreaders which are separate from the forms shall be removed entirely as the concrete is being placed. Adequate clean-out openings shall be proved for narrow walls and other locations where access to the bottom of the forms is not readily attainable. Prior to placing concrete, the facing of all forms shall be treated with oil or other bond breaking coating of such composition that it will not discolor or otherwise injuriously affect the concrete surface. Care shall be exercised to prevent coating of the reinforcing steel. (3) Metal Forms. The foregoing requirements for timber forms regarding design,mortar-tightness, filleted corners,beveled projections,bracing,alignment,removal,reuse and wetting shall also apply to metal forms, except that these will not require lining, unless specifically noted on the plans. The thickness of form metal shall be as required to maintain the true shape without warping or bulging. All bolt and rivet heads on the facing sides shall be countersunk. Clamps,pins or other connecting devices shall be designed to hold the forms rigidly together and to allow removal without injury to the concrete. Metal forms which do not present a smooth surface or line up properly shall not be used. Metal shall be kept free from rust, grease or other foreign materials. 6. PLACING REINFORCEMENT Reinforcement in concrete structures shall be placed carefully and accurately and rigidly supported as provided in the City Standard Specification Section 032020 'Reinforcing Steel". Reinforcing steel supports shall not be welded to I-beams or girders. 7. PLACING CONCRETE-GENERAL The minimum temperature of all concrete at the time of placement shall be not less than 50 degrees F. 038000 Page 7 of 19 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 The consistency of the concrete as placed should allow the completion of all finishing operations without the addition of water to the surface. When conditions are such that additional moisture is needed for finishing,the required water shall be applied to the surface by fog spray only,and shall be held to a minimum amount. Fog spray for this purpose may be applied with hand operated fogging equipment. The maximum time interval between the addition of cement to the batch and the placing of concrete in the forms shall not exceed the following: Air or Concrete Temperature Maximum Time Non-Aizitated Concrete: Above 80 degrees F 15 minutes Up to 80 degrees F 30 minutes AOtated Concrete: Above 90 degrees F 45 minutes 75 degrees F to 90 degrees F 60 minutes 35 degrees F to 74 degrees F 90 minutes The use of an approved retarding agent in the concrete will permit the extension of each of the above temperature-time maximums by 30 minutes for direct traffic culverts, and one hour for all other concrete except that the maximum time shall not exceed 30 minutes for non-agitated concrete. Before starting work,the Contractor shall inform the Engineer fully of the construction methods he proposes to use, the adequacy of which shall be subject to the approval of the Engineer. The Contractor shall give the Engineer sufficient advance notice before placing concrete in any unit of the structure to permit the inspection of forms,reinforcing steel placement,and other preparations. Concrete shall not be placed in any unit prior to the completion of formwork and placement of reinforcement therein. Concrete mixing, placing and finishing shall be done during daylight hours, unless adequate provisions are made to light the entire site of all operations. Concrete placement will not be permitted when impending weather conditions will impair the quality of the finished work. If rainfall should occur after placing operations are started,the Contractor shall provide ample covering to protect the work. In case of drop in temperature,the provisions set forth in Article "Placing Concrete in Cold Weather" of this specification shall be applied. The placing of concrete shall be regulated so the pressures caused by the plastic concrete shall not exceed the loads used in form design. 038000 Page 8 of 19 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 The method of handling, placing and consolidation of concrete shall minimize segregation and displacement of the reinforcement, and produce a uniformly dense and compact mass. Concrete shall not have a free fall of more than 5 feet,except in the case of thin walls such as in culverts. Any hardened concrete spatter ahead of the plastic concrete shall be removed. The method and equipment used to transport concrete to the forms shall be capable of maintaining the rate of placement approved by the Engineer. Concrete may be transported by buckets, chutes, buggies, belt conveyors,pumps or other acceptable methods. When belt conveyors or pumps are used, sampling for testing will be done at the discharge end. Concrete transported by conveyors shall be protected from sun and wind,if necessary,to prevent loss of slump and workability. Pipes through which concrete is pumped shall be shaded and/or wrapped with wet burlap, if necessary, to prevent loss of slump and workability. Concrete shall not be transported through aluminum pipes, tubes or other aluminum equipment. Chutes, troughs, conveyors or pipes shall be arranged and used so that the concrete ingredients will not be separated. When steep slopes are necessary, the chutes shall be equipped with baffle boards or made in short lengths that reverse the direction of movement, or the chute ends shall terminate in vertical downspouts. Open troughs and chutes shall extend, if necessary, down inside the forms or through holes left in them. All transporting equipment shall be kept clean and free from hardened concrete coatings. Water used for cleaning shall be discharged clear of the concrete. Each part of the forms shall be filled by depositing concrete as near its final position as possible. The coarse aggregate shall be worked back from the face and the concrete forced under and around the reinforcement bars without displacing them. Depositing large quantities at one point and running or working it along the forins will not be allowed. Concrete shall be deposited in the forms in layers of suitable depth but not more than 36 inches in thickness, unless otherwise directed by the Engineer. The sequence of successive layers or adjacent portions of concrete shall be such that they can be vibrated into a homogenous mass with the previously placed concrete without a cold j oint. Not more than one hour shall elapse between adjacent or successive placements of concrete. Unauthorized construction joints shall be avoided by placing all concrete between the authorized joints in one continuous operation. An approved retarding agent shall be used to control stress cracks and/or unauthorized cold joints in mass placements where differential settlement and/or setting time may induce stress cracking. Openings in forms shall be provided, if needed, for the removal of laitance of foreign matter of any kind. All forms shall be wetted thoroughly before the concrete is placed therein. All concrete shall be well consolidated and the mortar flushed to the form surfaces by continuous working with immersion type vibrators. Vibrators which operate by attachment to forms or reinforcement will not be permitted, except on steel forms. At least one stand-by vibrator shall be 038000 Page 9 of 19 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 provided for emergency use in addition to those required for placement. The concrete shall be vibrated immediately after deposit. Prior to the beginning of work, a systematic spacing of the points of vibration shall be established to insure complete consolidation and thorough working of the concrete around the reinforcement, embedded fixtures, and into the corners and angles of the forins. Immersion type vibrators shall be inserted vertically,at points 18 to 30 inches apart, and slowly withdrawn. The vibrator may be inserted in a sloping or horizontal position in shallow slabs. The entire depth of each lift shall be vibrated, allowing the vibrator to penetrate several inches into the preceding lift. Concrete along construction joints shall be thoroughly consolidated by operating the vibrator along and close to but not against the joint surface. The vibration shall continue until thorough consolidation,and complete embedment of reinforcement and fixtures is produced,but not long enough to cause segregation. Vibration may be supplemented by hand spading or rodding, if necessary,to insure the flushing of mortar to the surface of all forms. Slab concrete shall be mixed in a plant located off the structure. Carting or wheeling concrete batches over completed slabs will not be permitted until they have aged at least four(4)full curing days. If carts are used,timber planking will be required for the remainder of the curing period. Carts shall be equipped with pneumatic tires. Curing operations shall not be interrupted for the purpose of wheeling concrete over finished slabs. After concrete has attained its initial set,at least one(1)curing day shall elapse before placing strain on projecting reinforcement to prevent damage to the concrete. The storing of reinforcing or structural steel on completed roadway slabs generally shall be avoided and, when permitted, shall be limited to quantities and distribution that will not induce excessive stresses. 8. PLACING CONCRETE IN COLD WEATHER (1) Cast-in-Place Concrete. Concrete may be placed when the atmospheric temperature is not less than 35 degrees F. Concrete shall not be placed in contact with any material coated with frost or having a temperature less than 32 degrees F. Aggregates shall be free from ice, frost and frozen lumps. When required, in order to produce the minimum specified concrete temperature,the aggregate and/or the water shall be heated uniformly, in accordance with the following: The water temperature shall not exceed 180 degrees F,and/or the aggregate temperature shall not exceed 150 degrees F. The heating apparatus shall heat the mass of aggregate uniformly. The temperature of the mixture of aggregates and water shall be between 50 degrees F and 85 degrees F before introduction of the cement. All concrete shall be effectively protected as follows: (a) The temperature of slab concrete of all unformed surfaces shall be maintained at 50 degrees F or above for a period of 72 hours from time of placement and above 40 degrees F for an additional 72 hours. 038000 Page 10 of 19 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 (b) The temperature at the surface of all concrete in piers, culverts walls,retaining walls,parapets,wingwalls,bottoms of slabs,and other similar formed concrete shall be maintained at 40 degrees F or above for a period of 72 hours from time of placement. (c) The temperature of all concrete,including the bottom slabs of culverts placed on or in the ground, shall be maintained above 32 degrees F for a period of 72 hours from time of placement. Protection shall consist of providing additional covering, insulated forms or other means, and if necessary, supplementing such covering with artificial heating. Curing as specified under Article "Curing Concrete"of this specification shall be provided during this period until all requirements for curing have been satisfied. When impending weather conditions indicate the possibility of the need for such temperature protection, all necessary heating and covering material shall be on hand ready for use before pennission is granted to begin placement. Sufficient extra test specimens will be made and cured with the placement to ascertain the condition of the concrete as placed,prior to form removal and acceptance. (2) Precast Concrete. A fabricating plant for precast products which has adequate protection from cold weather in the form of permanent or portable framework and covering, which protects the concrete when placed in the forms,and is equipped with approved steam curing facilities,may place concrete under any low temperature conditions provided: (a) The framework and covering are placed and heat is provided for the concrete and the forms within one hour after the concrete is placed. This shall not be construed to be one hour after the last concrete is placed,but that no concrete shall remain unprotected longer than one hour. (b) Steam heat shall keep the air surrounding the concrete between 50 degrees F and 85 degrees F for a minimum of three hours prior to beginning the temperature rise which is required for steam curing. (c) For fabricating plants without the above facilities and for job site precast products,the requirements of the Article "Curing Concrete" of this specification shall apply. The Contractor is responsible for the protection of concrete placed under any and all weather conditions. Permission given by the Engineer for placing concrete during freezing weather will in no way relieve the Contractor of the responsibility for producing concrete equal in quality to that placed under normal conditions. Should concrete placed under such conditions prove unsatisfactory,it shall be removed and replaced at no additional cost. 038000 Page 11 of 19 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 9. PLACING CONCRETE IN WATER Concrete shall be deposited in water only when specified on the plans or with written permission by the Engineer. The forms or cofferdams shall be sufficiently tight to prevent any water current passing through the space in which the concrete is being deposited. Pumping will not be permitted during the concrete placing, nor until it has set for at least 36 hours. The concrete shall be placed with a tremie, closed bottom-dump bucket, or other approved method, and shall not be permitted to fall freely through the water nor shall it be disturbed after it has been placed. The concrete surface shall be kept approximately level during placement. The tremie shall consist of a water-tight tube 14 inches or less in diameter. It shall be constructed so that the bottom can be sealed and opened after it is in place and fully charged with concrete. It shall be supported so that it can be easily moved horizontally to cover all the work area and vertically to control the concrete flow. Bottom-dump buckets used for underwater placing shall have a capacity of not less than one-half cubic yard. It shall be lowered gradually and carefully until it rests upon the concrete already placed and raised very slowly during the upward travel;the intent being to maintain still water at the point of discharge and to avoid agitating the mixture. The placing operations shall be continuous until the work is complete. 10. PLACING CONCRETE IN BOX CULVERTS In general, construction joints will be permitted only where shown on the plans. Where the top slab and walls are placed monolithically in culverts more than 4 feet in clear height, an interval of not less than one (1)nor more than two (2)hours shall elapse before placing the top slab to allow for shrinkage in the wall concrete. The base slab shall be finished accurately at the proper time to provide a smooth uniform surface. Top slabs which carry direct traffic shall be finished as specified for roadway slabs in Article"Finish of Roadway Slabs". Top slabs of fill type culverts shall be given a reasonably smooth float finish. 11. PLACING CONCRETE IN FOUNDATIONS AND SUBSTRUCTURE Concrete shall not be placed in footings until the depth and character of the foundation has been inspected by the Engineer and permission has been given to proceed. Placing of concrete footings upon seal concrete courses will be permitted after the caissons or cofferdams are free from water and the seal concrete course cleaned. Any necessary pumping or bailing during the concreting operation shall be done from a suitable sump located outside the forms. All temporary wales or braces inside cofferdams or caissons shall be constructed or adjusted as the work proceeds to prevent unauthorized construction joints in footings or shafts. 038000 Page 12 of 19 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 When footings can be placed in a dry excavation without the use of cofferdams or caissons, forms may be omitted,if desired by the Contractor and approved by the Engineer,and the entire excavation filled with concrete to the elevation of the top of footing; in which case, measurement for payment will be based on the footing dimensions shown on the plans. 12. TREATMENT AND FINISHING OF HORIZONTAL SURFACES EXCEPT ROADWAY SLABS All unformed upper surfaces shall be struck off to grade and finished. The use of mortar topping for surfaces under this classification will not be permitted. After the concrete has been struck off, the surface shall be floated with a suitable float. Sidewalks shall be given a wood float or broom finish, or may be striped with a brush, as specified by the Engineer. Other surfaces shall be wood float finished and striped with a fine brush leaving a fine- grained texture. 13. FINISH OF ROADWAY SLABS As soon as the concrete has been placed and vibrated in a section of sufficient width to permit working,the surface shall be approximately leveled,struck off and screeded,carrying a slight excess of concrete ahead of the screed to insure filling of all low spots. The screed shall be designed rigid enough to hold true to shape and shall have sufficient adjustments to provide for the required camber. A vibrating screed may be used if heavy enough to prevent undue distortion. The screeds shall be provided with a metal edge. Longitudinal screeds shall be moved across the concrete with a saw-like motion while their ends rest on headers or templates set true to the roadway grade or on the adjacent finished slab. The surface of the concrete shall be screeded a sufficient number of times and at such intervals to produce a uniform surface, true to grade and free of voids. If necessary, the screeded surface shall be worked to smooth finish with a long handled wood or metal float of the proper size, or hand floated from bridges over the slab. When required by the Engineer, the Contractor shall perform sufficient checks with a long handled 10-foot straightedge on the plastic concrete to insure that the final surface will be within the tolerances specified below. The check shall be made with the straightedge parallel to the centerline. Each pass thereof shall lap half of the preceding pass. All high spots shall be removed and all depressions over one-sixteenth inch(1/16")in depth shall be filled with fresh concrete and floated. The checking and floating shall be continued until the surface is true to grade and free of depressions, high spots, voids or rough spots. Rail support holes shall be filled with concrete and finished to match the top of the slab. Surface Texturing. Perform surface texturing using a either carpet drag or metal tining as indicated on the drawings. Complete final texturing before the concrete has attained its initial set. Draw the carpet drag 038000 Page 13 of 19 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 longitudinally along the pavement surface with the carpet contact surface area adjusted to provide a satisfactory coarsely textured surface. A metal-tine texture finish is required using a tining machine unless otherwise shown on the plans. Provide the metal-tine finish immediately after the concrete surface has set enough for consistent tining. Operate the metal-tine device to obtain grooves spaced at 1 in., approximately 3/16 in. deep, with a minimum depth of 1/8 in., and approximately 1/12 in. wide. Do not overlap a previously tined area. Use manual methods for achieving similar results on ramps and other irregular sections of pavements. Repair damage to the edge of the slab and joints immediately after texturing. Do not tine pavement that will be overlaid. Upon completion of the floating and/or straight edging and before the disappearance of the moisture sheen, the surface shall be given a broom or burlap drag finish. The grooves of these finishes shall be parallel to the structure centerline. It is the intent that the average texture depth resulting from the number of tests directed by the Engineer be not less than 0.035 inch with a minimum texture depth of 0.030 inch for any one test when tested in accordance with TxDOT Test Method Tex-436-A. Should the texture depth fall below that intended, the finishing procedures shall be revised to produce the desired texture. After the concrete has attained its final set, the roadway surface shall be tested with a standard 10- foot straightedge. The straightedge shall be placed parallel to the centerline of roadway to bridge any depressions and touch high spots. Ordinates of irregularities measured from the face of the straightedge to the surface of the slab shall not exceed one-eighth of an inch(1/8"),making proper allowances for camber,vertical curvature and surface texture. Occasional variations,not exceeding three-sixteenth of an inch (3/16") will be acceptable, if in the opinion of the Engineer it will not affect the riding qualities. When directed by the Engineer, irregularities exceeding the above requirements shall be corrected. In all roadway slab finishing operations,camber for specified vertical curvature and transverse slopes shall be provided. 14. CURING CONCRETE The Contractor shall inform the Engineer fully of the methods and procedures proposed for curing; shall provide the proper equipment and material in adequate amounts; and shall have the proposed methods, equipment and material approved prior to placing concrete. Inadequate curing and/or facilities,therefore,shall be cause for the Engineer to stop all construction on the job until remedial action is taken. All concrete shall be cured for a period of four(4) curing days except as noted herein. 038000 Page 14 of 19 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 EXCEPTIONS TO 4-DAY CURING Description Required Curing Upper Surfaces of Bridge Slabs and 8 curing days (Type I or III) cement Top Slabs of Direct Traffic Culverts 10 curing days (Type 11 cement) Concrete Piling (non-prestressed) 6 curing days When the air temperature is expected to drop below 35 degrees F,the water curing mats shall be covered with polyethylene sheeting, burlap-polyethylene blankets or other material to provide the protection required by Article "Placing Concrete in Cold Weather" of these specifications. A curing day is defined as a calendar day when the temperature, taken in the shade away from artificial heat, is above 50 degrees F for at least 19 hours (colder days if satisfactory provisions are made to maintain the temperature of all surfaces of the concrete above 40 degrees F for the entire 24 hours). The required curing period shall begin when all concrete therein has attained its initial set. The following methods are permitted for curing concrete subject to the restrictions of Table I and the following requirements for each method of curing. (1) Form Curing. When forms are left in contact with the concrete, other curing methods will not be required except for cold weather protection. (2) Water Curing. All exposed surfaces of the concrete shall be kept wet continuously for the required curing time. The water used for curing shall meet the requirements for concrete mixing water as specified in the specification Section 030020 "Portland Cement Concrete". Seawater will not be permitted. Water which stains or leaves an unsightly residue shall not be used. (a) Wet Mat. Cotton mats shall be used for this curing method. They shall be placed as soon as possible after the surface has sufficiently hardened to prevent damage to the concrete. (See Article, 'Placing Concrete" of this specification.) Damp burlap blankets made from nine-ounce stock may be placed on the damp concrete surface for temporary protection prior to the application of the cotton mats which may be placed dry and wetted down after placement. The mats shall be weighted down adequately to provide continuous contact with all concrete surfaces where possible. The surfaces of the concrete shall be kept wet for the required curing time. Surfaces which cannot be cured by contact shall be enclosed with mats and anchored positively to the forms or to the ground so that outside air cannot enter the enclosure. Sufficient moisture shall be provided inside the enclosure to keep all surfaces of the concrete wet. (b) Water Spray. This curing method shall consist of overlapping sprays or sprinklers that keep all unformed surfaces continuously wet. (c) Ponding. This curing method requires the covering of the surfaces with a minimum of two inches (2") of clean granular material,kept wet at all times, or a minimum of one-inch 038000 Page 15 of 19 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 (1") depth of water. Satisfactory provisions shall be made to provide a dam to retain the water or saturated granular material. (3) Membrane Curing. This consists of curing concrete pavement,concrete pavement(base),curbs, gutters, retards, sidewalks, driveways, medians, islands, concrete riprap, cement-stabilized riprap, concrete structures and other concrete as indicated on the plans by impervious membrane method. Unless otherwise provided herein or shown on the plans, either Type 1-D or Type 2 membrane curing compound may be used where permitted except that Type 1-D (Resin Base Only) will be required for slab concrete in bridge decks and top slabs of direct traffic culverts.

Formed surfaces and surfaces which have been given a first rub shall be dampened and shall be moist at the time of application of the membrane. When membrane is used for complete curing, the film shall remain unbroken for the minimum curing period specified. Membrane which is damaged shall be corrected immediately by reapplication of membrane. Unless otherwise noted herein or on the plans,the choice of membrane type shall be at the option of the Contractor. Only one type of curing compound will be permitted on any one structure. The membrane curing compound shall be applied after the surface finishing has been completed,and immediately after the free surface moisture has disappeared. The surface shall be sealed with a single uniform coating of curing compound applied at the rate of coverage recommended by the manufacturer and directed by the Engineer, but not less than I gallon per 180 square feet of area. The Contractor shall provide satisfactory means and facilities to properly control and check the rate of application of the compound. The compound shall be thoroughly agitated during its use and shall be applied by means of approved mechanical power pressure sprayers. The sprayers used to apply the membrane to concrete pavement or concrete pavement (base) shall travel at uniform speed along the forms and be mechanically driven. The equipment shall be of such design that it will insure uniforrn and even application of the membrane material. The sprayers shall be equipped with satisfactory atomizing nozzles. Only on small miscellaneous items will the Contractor be permitted to use hand-powered spray equipment. For all spraying equipment, the Contractor shall provide facilities to prevent the loss of the compound between the nozzle and the concrete surface during the spraying operations. The compounds shall not be applied to a dry surface. If the surface of the concrete has become dry, it shall be moistened prior to application of membrane by fogging or mist application. Sprinkling or coarse spraying will not be allowed. At locations where the coating shows discontinuities,pinholes or other defects,or if rain falls on the newly-coated surface before the film has dried sufficiently to resist damage,an additional coat of the compound shall be applied immediately at the same rate of coverage specified herein. To insure proper coverage, the Engineer shall inspect all treated areas after application of the compound for the period of time designated in the governing specification for curing, either for membrane curing or for other methods. Should the foregoing indicate that any area during the curing period is not protected, an additional coat or coats of the compound shall be applied immediately, and the rate of application of the membrane compound shall be increased until all areas are uniformly covered. When temperatures are such as to warrant protection against freezing, curing by this method shall be supplemented with an approved insulating material capable of protecting the concrete for the specified curing period. If at any time there is reason to believe that this method of curing is unsatisfactory or is detrimental 038000 Page 17 of 19 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 to the work,the Contractor,when notified, shall immediately cease the use of this method and shall change to curing by one of the other methods specified under this contract. 15. REMOVAL OF FORMS Except as herein provided, forms for vertical surfaces may be removed when the concrete has aged not less than one day(24 hours)when Type I and Type II cement is used, and not less than one-half day (12 hours) when Type III cement is used, provided it can be done without damage to the concrete. Forms for inside curb faces may be removed in approximately three hours provided it can be done without damage to the curb. 16. FINISHING EXPOSED SURFACES Concrete shall be finished as required in the specification Section for the respective item or as otherwise specified on the plans. An ordinary surface finish shall be applied to all concrete surfaces either as a final finish or preparatory to a higher finish. Ordinary Surface Finish shall be as follows: After form removal, all porous or honey-combed areas and spalled areas shall be corrected by chipping away all loose or broken material to sound concrete. Feather edges shall be eliminated by cutting a face perpendicular to the surface. Shallow cavities shall be repaired using adhesive grout or epoxy grout. If judged repairable by the Engineer, large defective areas shall be corrected using concrete or other material approved by the Engineer. Holes and spalls caused by removal of metal ties, etc., shall be cleaned and filled with adhesive grout or epoxy grout. Exposed parts of metal chairs on surfaces to be finished by rubbing, shall be chipped out to a depth of one-half inch (1/2") and the surface repaired. All fins,runs, drips or mortar shall be removed from surfaces which remain exposed. Form marks and chamfer edges shall be smoothed by grinding and/or dry rubbing. Grease, oil, dirt, curing compound, etc., shall be removed from surfaces requiring a higher grade of finish. Discolorations resulting from spillage or splashing of asphalt,paint or other similar material shall be removed. Repairs shall be dense, well bonded and properly cured, and when made on surfaces which remain exposed and do not require a higher finish, shall be finished to blend with the surrounding concrete. 038000 Page 18 of 19 Rev.3-25-2015 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 17.

Sunwood Drive to Staples Street, Corpus Christi, Texas RETL Job Number: G121260 MSA No. 3399, Project No. 21063, Task Order No. 6 INTRODUCTION This report presents the results of a subsurface investigation, laboratory testing program, and geotechnical analysis for the proposed Lipes Boulevard Reconstruction project, from Sunwood Drive to Staples Street, in Corpus Christi, Texas. Authorization The work for this project was performed in accordance with Rock Engineering and Testing Laboratory, Inc. (RETL) proposal number P042921 B, dated April 29, 2021. The scope of work and fee was approved on May 7, 2021, by provision of City of Corpus Christi Task Order No. 6, under the MSA for Geotech/Construction Materials Testing Contract No. 3399. The Task Order was electronically provided to RETL. Purpose and Scope The purpose of this exploration was to evaluate the existing pavement and subsurface materials and soil subgrade conditions at five locations along Lipes Boulevard, from Sunwood Drive to Staples Street, and to provide pavement reconstruction recommendations and foundation recommendations for support of potential new traffic signals. The scope of the exploration and analysis included the subsurface exploration, field and laboratory testing, engineering analysis and evaluation of the subsurface soils, provision of pavement and traffic signal foundation recommendations, and preparation of this report. The scope of services did not include an environmental assessment. Any statements in this report, or on the boring logs, regarding odors, colors, unusual or suspicious items or conditions are strictly for the information of the client. General The exploration and analysis of the subsurface conditions reported herein are considered sufficient in detail and scope to provide pavement and traffic signal foundation recommendations for the proposed project. The information submitted for the proposed project is based on project details provided by Ms. Mai Bernal, P.E., representing the City of Corpus Christi, and the soil information obtained at the boring locations.

Sunwood Drive to Staples Street, Corpus Christi, Texas RETL Job Number: G121260 MSA No. 3399, Project No. 21063, Task Order No. 6 This report has been prepared for the exclusive use of the City of Corpus Christi and the design team for the proposed Lipes Boulevard Reconstruction project, from Sunwood Drive to Staples Street, in Corpus Christi, Texas. DESCRIPTION OF SITE The site of the proposed Lipes Boulevard Reconstruction project is located in Corpus Christi, Texas. Lipes Boulevard is an asphalt-surfaced, two-lane roadway with curb and gutter. The portion of the existing street included in this project is approximately 0.51 miles long and 36 feet wide and extends between Sunwood Drive and Staples Street. Commercial and residential properties border the north side of Lipes Boulevard. The south side of Lipes Boulevard is bordered by commercial and residential properties, as well as undeveloped property. Overhead utilities are present parallel to and along the north side of the road. Evidence of below grade utilities were observed on both sides of the road. The general location is illustrated on the Site Vicinity Map located in the Appendix of this report. FIELD EXPLORATION Scope The field exploration, to evaluate the engineering characteristics of the subsurface materials, included reconnaissance of the project site, coring of the existing pavement constituents, performing the boring operations and obtaining disturbed split spoon samples and relatively undisturbed Shelby tube samples of the subgrade soils. During the sample recovery operations, the thickness of the pavement and underlying base materials were measured, while the subgrade soils encountered to the boring termination depths of 6 to 25 feet were classified and recorded on the boring logs in accordance with "Standard Guide for Field Logging of Subsurface Exploration of Soil and Rock, (ASTM D5434)." As requested, five pavement cores and soil borings were performed for the purpose of obtaining existing pavement materials and thicknesses, as well as providing information regarding existing groundwater and subgrade soil information. The table below provides the boring identification, boring depths and GPS coordinates.

Sunwood Drive to Staples Street, Corpus Christi, Texas RETL Job Number: G121260 MSA No. 3399, Project No. 21063, Task Order No. 6 The City of Corpus Christi determined the number, depth and general locations of the borings. RETL determined the specific and final locations of the borings and performed the drilling operations. The GPS coordinates were obtained at the boring locations using a Garmin GPS model eTrex and are provided in this report and on the boring logs. Upon completion of the drilling operations and obtaining the groundwater observations, the borings were backfilled with excess soils obtained during drilling operations and the surface was patched with cold-patch asphalt. A Boring Location Plan is provided in the Appendix of this report. The borings performed for this project were used to determine the classification and strengths of the subgrade soils. The information provided on the boring logs includes boring location, boring depth, pavement material types and thicknesses, soil classification, soil strengths, and laboratory test results. The boring logs are included in the Appendix. Drilling and Sampling Procedures At the boring locations, the pavement constituents were cored using a diamond core barrel until subgrade soils were encountered. After coring, the pavement constituents were removed and measured for thickness. A drill rig equipped with a rotary head turning solid stem and hollow stem augers was used to advance the borings to termination depths of 6 and 25 feet. Disturbed samples were obtained employing split-barrel sampling procedures in general accordance with the procedures for "Penetration Test and Split-Barrel Sampling of Soils, (ASTM D1586)". Relatively undisturbed soil samples were obtained using thin-wall tube sampling procedures in general accordance with, "Thin Walled Tube Sampling of Soils, (ASTM D1587)." The samples obtained by this procedure were extruded by a hydraulic ram in the field. The samples were placed in plastic bags, marked according to boring numbers, depths, and any other pertinent field data, stored in special containers, and delivered to the laboratory for testing. Field Tests and Observations Standard Penetration Tests (SPTs)— During the sampling procedures, SPTs were performed to obtain the standard penetration value of the soil at selected intervals. The standard penetration value (N) is defined as the number of blows of a 140-pound hammer, falling 30 inches, required to advance the split-barrel sampler 1 foot into the soil. The sampler is lowered to the bottom of the previously cleaned drill hole and advanced by blows from the hammer. The number of blows is recorded for each of three successive 6-inch penetrations. The "N" value is obtained by adding the second and third 6-inch increment number of blows. An automatic hammer was utilized when performing SPTs. An automatic hammer is usually taken as having an efficiency of one. The results of standard penetration tests indicate the relative density of cohesionless soils and comparative consistency of cohesive soils, thereby providing a basis for estimating the relative strength and compressibility of the soil profile components.

Sunwood Drive to Staples Street, Corpus Christi, Texas RETL Job Number: G121260 MSA No. 3399, Project No. 21063, Task Order No. 6 Water Level Observations — Water level observations were obtained during the test boring operations. Water level observations are noted on the boring logs provided in the Appendix. In relatively pervious soils, such as sands, the indicated depths are usually reliable groundwater levels. In relatively impervious soils, such as clays, a suitable estimate of the groundwater depth may not be possible, even after several days of observation. Seasonal variations, temperature, land-use, proximity to water bodies and recent rainfall conditions may influence the depth to the groundwater. The amount of water in open boreholes largely depends on the permeability of the soils encountered at the boring locations. Ground Surface Elevations — The ground surface elevations at the boring locations were not provided at the time of this report. Therefore, the depths referred to in this report are from the actual ground surface at the boring locations during the time of our field investigation. LABORATORY TESTING PROGRAM In addition to the field investigation, a laboratory testing program was conducted to determine additional pertinent engineering characteristics of the subsurface materials necessary in analyzing the behavior of the pavement systems for the proposed project. The laboratory testing program included supplementary visual classification (ASTM D2487) and water content tests (ASTM D2216) on the samples. In addition, selected samples were subjected to Atterberg limits tests (ASTM D4318) and percent material finer than the#200 sieve tests (ASTM D1140). The shear strengths of selected cohesive soil samples were evaluated from unconfined compressive strength tests (ASTM D2166). The estimated soil strengths were obtained using a hand penetrometer. Selected samples of base material featuring gravel particles was sieved over a #4 Sieve to determine the percent gravel within the base material. The laboratory testing program was conducted in general accordance with applicable ASTM Specifications. The results of these tests are to be found on the accompanying boring logs provided in the Appendix. SUBSURFACE CONDITIONS General The types of surficial and subsurface materials encountered in the borings have been visually classified and are described in detail on the boring logs. The results of the standard penetration tests, water level observations and laboratory tests are presented on the boring logs. Representative samples of the soils were placed in polyethylene bags and are now stored in the laboratory for further analysis, if desired. Unless notified to the contrary, the samples will be disposed of three months after issuance of this report.

Sunwood Drive to Staples Street, Corpus Christi, Texas RETL Job Number: G121260 MSA No. 3399, Project No. 21063, Task Order No. 6 The stratification of the soil, as shown on the boring logs, represents the soil conditions at the actual boring locations. Variations may occur between, or beyond, the boring locations. Lines of demarcation represent the approximate boundary between different soil types, but the transition may be gradual, or not clearly defined. It should be noted that, whereas the test borings were drilled and sampled by experienced drillers, it is sometimes difficult to record changes in stratification within narrow limits. In the absence of foreign substances, it is also difficult to distinguish between discolored soils and clean soil fill. Existing Pavement Materials The existing pavement material types and approximate thicknesses encountered at the boring locations have been summarized and are provided in the following table.

Sunwood Drive to Staples Street, Corpus Christi, Texas RETL Job Number: G121260 MSA No. 3399, Project No. 21063, Task Order No. 6 The maximum allowable slopes during construction for OSHA soil types are provided in the following table. Guidelines For Maximum Allowable Slopes Soil or Rock Type Max. Allow. Slopes for Excavations <Than 20' Deep Stable Rock Vertical Type A 3/: Horizontal: 1 Vertical Type B 1 Horizontal: 1 Vertical Type C 1'/2 Horizontal: 1 Vertical Guidelines for maximum allowable slopes were obtained from OSHA documents, but do not take into account any recent revisions or the stability of long-term unprotected slopes. Long term unprotected slopes will likely require flatter slopes. The guidelines presented herein for slopes does not imply RETL is taking responsibility for construction site safety, this responsibility falls entirely upon the contractor and his competent person. RETL is assuming that the contractor will comply with all rules, ordinances and other requirements to comply with safe construction practices. Groundwater Observations Groundwater (GW) observations and the depth the borings caved are provided in the following table. Groundwater(GW) Observations Boring During Drilling Upon Completion B-1 18 feet Wet and caved at 15 feet B-2 Dry Dry and open B-3 Dry Dry and open B-4 18.5 feet Wet and caved at 17 feet B-5 Dry Dry and open Based on observations made in the field, it appears as if the groundwater at this site at the time of our field investigation is at a depth of approximately 18 feet. Water levels in open boreholes were observed to rise to depths of 15 to 17 feet below the existing ground surface. Water levels in open boreholes may require several hours to several days to stabilize depending on the permeability of the soils and groundwater levels at this site may be subject to seasonal conditions, recent rainfall, proximity to large bodies of water, and drought or temperature effects.

Sunwood Drive to Staples Street, Corpus Christi, Texas RETL Job Number: G121260 MSA No. 3399, Project No. 21063, Task Order No. 6 PROJECT DISCUSSION Project Description Based on information provided to RETL, the project will include reconstruction of Lipes Boulevard, between Sunwood Drive and Staples Street, in Corpus Christi, Texas. This portion of Lipes Boulevard is approximately 36 feet wide and is 0.51 miles long. The two-lane roadway is designated as a Collector Street and will be reconstructed with the existing curb and gutters. The reconstruction will consider both rigid and flexible pavement options. The project may also include the installation of two new traffic signals with new foundations, poles and mast arm signals. Traffic light standards will be supported on cast-in-place concrete drilled shafts. Conventional straight shaft drilled piers can be utilized at the sites to support the proposed traffic signal structures. Potential Vertical Rise (PVR) Discussion Differential vertical movements associated with the shrinking and swelling of plastic clayey soils is often a concern that needs to be addressed during the design and construction process. The estimated potential vertical rise (PVR) along the explored portion of Lipes Boulevard is on the order of 3'/2 to 4 inches. The PVR was calculated using the Texas Department of Transportation Method TEX-124E and took into account the depth of the active zone, estimated to be a depth of approximately 15 feet, and the Atterberg limits test results of the soils encountered within the active zone. The PVR value represents the vertical rise that can be experienced by dry subsoils if they are subjected to conditions that allow them to become saturated, such as poor drainage. The actual movement of the subsoils is dependent upon their change in moisture content. PVR reduction in pavement areas is typically not performed in the local area. If the project will include movement sensitive structures or if the City of Corpus Christi desires or requires to reduce the PVR value in the roadway area, RETL should be contacted for the appropriate recommendations. PAVEMENT CONSIDERATIONS The conditions that influence pavement design can be summarized as follows: • Bearing values of the subgrade. These can be represented by a California Bearing Ratio (CBR) for the design of flexible pavements, or a Modulus of Subgrade Reaction (K) for rigid pavements. • Vehicular traffic, in terms of the number and frequency of vehicles and their range of axle loads, • Probable increase in vehicular use over the life of the pavement, and • The availability of suitable materials to be used in the construction of the pavement and their relative costs.

Sunwood Drive to Staples Street, Corpus Christi, Texas RETL Job Number: G121260 MSA No. 3399, Project No. 21063, Task Order No. 6 Specific laboratory testing to define the subgrade strength (i.e. CBR/K values) has not been performed for this analysis. Based upon local experience and soil classifications, the estimated CBR and K values for the average subgrade soil condition along the proposed pavement reconstruction project are 3 and 100 pci, respectively. The portion of Lipes Boulevard to be reconstructed will be designed in general accordance with the City of Corpus Christi Infrastructure Design Manual and subsequent design instructions provided by the City of Corpus Christi. RETL has been informed that this section of Lipes Boulevard is designated as a "Collector Street". A 24-hour traffic study, performed on June 8, 2021, by Maldonado-Burkett, LLP, was provided by The City of Corpus Christi. RETL has reviewed the information provided in the traffic study and has used a one-directional Average Daily Traffic (ADT) of 1,703 with 2 percent truck traffic. Based on a 30-year pavement design life and a 2 percent growth rate, the design year travel lane ADT is 3,085. Based on this information, the design 18-Kip Equivalent Single Axle Loads (ESAL) were calculated to be less than or equal to 2,000,000 for both flexible and rigid pavements. The prescribed minimum design 18-Kip Equivalent Single Axle Loads (ESAL) for a Collector Street, as outlined in the City of Corpus Christi Infrastructure Design Manual, is 2,000,000. Accordingly, the recommendations in this report are based upon the prescribed minimum ESALs contained in the City of Corpus Christi Infrastructure Design Manual, as well as the pavement design parameters provided in the table below.

Sunwood Drive to Staples Street, Corpus Christi, Texas RETL Job Number: G121260 MSA No. 3399, Project No. 21063, Task Order No. 6 Rigid Pavement Recommendations The use of concrete for paving has become more prevalent in recent years due to a decrease in the material cost of concrete and the long-term maintenance cost benefits of concrete pavement compared to asphaltic pavements. The recommended rigid pavement section calculated using the American Association of the State Highway and Transportation Officials, "GUIDE FOR DESIGN OF PAVEMENT STRUCTURES," are provided in the following table. Recommended Rigid Pavement Section Collector Street Pavement Constituent (2,000,000 ESALs) Option 1 Option 2 Option 3 Reinforced Concrete 8 inches 8 inches 8 inches Hot Mix Asphaltic Concrete, Type D --- 1 inch --- Crushed Limestone Base (Type A Gr. 1-2) 6 inches --- --- Cement Stabilized Caliche Base (4%) --- 6 inches --- Lime Stabilized Subgrade (6'/z%) --- --- 8 inches Reinforced Concrete - The concrete pavement should be reinforced and jointed as per applicable TxDOT specifications and should have a minimum 28-day flexural strength of 620 psi. Expansion joints should be sealed with an appropriate sealant so that moisture infiltration into the subgrade soils and resultant concrete deterioration at the joints is minimized. The joints should be thoroughly cleaned, and sealant should be installed without overfilling before pavement is opened to traffic. Crushed Limestone Base Material - Crushed limestone base materials in rigid pavement areas should meet the requirements set forth in Texas Standard Specifications 2014; Item 247, Type A, Grade 1-2 and should be placed in maximum 8-inch thick loose lifts and compacted to a minimum density of 95 percent of the maximum dry density as determined by the standard Proctor test (ASTM D698) and within ± 1'/2 percent of the optimum moisture content. Cement Stabilized Caliche Base— Cement stabilization of the existing and reclaimed caliche base shall be performed in accordance with Texas Standard Specifications 2014; Item 275, "CEMENT TREATMENT (ROAD MIXED)." Cement shall be properly mixed at a minimum rate of 4 percent of the maximum dry unit weight as determined by ASTM D698. The cement stabilized caliche base should be compacted within 2 hours of mixing to a minimum density of 95 percent of the maximum dry unit weight of the cement stabilized base, as determined by a standard Proctor test (ASTM D698), and within ± 1'/2 percent of the optimum moisture content. Subgrade Preparation After all deleterious materials and existing roadway materials have been removed to the required subgrade elevation, the exposed subgrade soils shall be proof-rolled to identify any soft or yielding locations. The subgrade shall be proofrolled in accordance with Texas Department of Transportation Standard Specification Item 216; "PROOF ROLLING". The equipment performing the proof rolling shall be a pneumatic tire roller with minimum weight of 25 tons and maximum weight of 50 tons. Page 11 of 16 DocuSign Envelope ID: E921FEAl-502E-461D-A492-2EOFB27AB587 June 25, 2021 LIPES BOULEVARD RECONSTRUCTION (21063) Attn: Ms. Mai Bernal, P.E. Sunwood Drive to Staples Street, Corpus Christi, Texas RETL Job Number: G121260 MSA No. 3399, Project No. 21063, Task Order No. 6 The roller shall meet the requirements of Texas Department of Transportation Standard Specification Item 210; Section 210.2.D, "Pneumatic Tire Rollers." The contact pressure shall be less than or equal to 150 psi for a pneumatic tire roller that weighs between 25 to 50 tons. A pneumatic tire roller weighing between 25 to 50 tons is a "Heavy Pneumatic". Any soft or yielding areas identified shall be removed to firm soils, reworked and recompacted in place to obtain a stable and non-yielding subgrade. After proof-rolling and any necessary remediation, and if a pavement section without lime stabilization will be used, the upper 12 inches of exposed subgrade soils shall be compacted to a minimum density of 98 percent of the maximum dry unit weight of the raw subgrade soils as determined by a standard Proctor test (ASTM D698) and at, or above, the optimum moisture content. Where a pavement section containing geogrid will be used, after proper compaction of the subgrade, a layer of the specified geogrid shall be placed on the properly prepared raw subgrade and shall extend outside the limits of the crushed limestone base material. The geogrid shall be placed in accordance with the manufacturer's recommendations. Where a pavement section containing lime-stabilized subgrade will be used, then upon completion of proof rolling, the lime stabilization operations shall be performed in accordance with TxDOT Item 260, "LIME TREATMENT FOR MATERIALS USED AS SUBGRADE (ROAD MIXED)." Based on the results of the Atterberg limits testing for the subgrade soils, curves provided in TxDOT Test Method 121-E, and the City of Corpus Christi design requirements, RETL recommends that the lime be mixed at the rate of 6'/2 percent, based on the maximum dry unit weight of the raw subgrade soils as determined by the standard Proctor test (ASTM D698). The lime stabilized soils should be compacted to a minimum density of 98 percent of the maximum dry density, as determined by a standard Proctor test (ASTM D698), and at, or above, the optimum moisture content. Specifications Any other pay items not specifically referenced herein shall be either City of Corpus Christi specifications or TxDOT specifications. All TxDOT specifications are referenced from the 2014 Texas Department of Transportation, "STANDARD SPECIFICATIONS FOR CONSTRUCTION OF HIGHWAYS, STREETS AND BRIDGES." Routine Maintenance of Flexible and Rigid Pavement Systems The pavement sections provided in this report are designed based on the indicated 18-kip equivalent single axle loads. During the design life, the roadway will require routine maintenance such as crack sealing and seal coats for flexible pavements and joint maintenance for rigid pavement sections in order to achieve a desirable life of pavement. Without proper maintenance, moisture infiltration into the base material and subgrade will result in rapid deterioration of the pavement system. RETL recommends that the City of Corpus Christi protect their investment by incorporating an aggressive maintenance program.

Sunwood Drive to Staples Street, Corpus Christi, Texas RETL Job Number: G121260 MSA No. 3399, Project No. 21063, Task Order No. 6 TRAFFIC LIGHT FOUNDATION RECOMMENDATIONS The design of the drilled shaft foundations for support of the traffic light standards can be performed by the structural engineer using conventional drilled shaft design techniques that utilize allowable unit soil values for proportioning the foundations to resist design axial and lateral loads. It is our understanding that the City of Corpus Christi has previously utilized the Texas Department of Transportation Traffic Signal Pole Foundation Standard TS-FD-12 design methodology, which includes prescribed shaft design based upon the Texas cone Penetrometer (TCP) values. Accordingly, we are providing design information and recommendations in the following sections for both of these described design methods. Drilled Pier Recommendations The structural designer can utilize the allowable unit skin friction values for the range in depths included in the following table for straight shaft drilled piers to resist the axial loads given the strengths of the subsurface soils encountered. Allowable Unit Skin Friction Values Depth Below Existing Grade (ft) Allowable Unit Skin Friction (psf) 0 - 5 Neglect 5- 13 350 13- 18 250 18-22 200 All depths are referenced from the existing ground surface elevations at the boring locations during the time of our field investigation. The allowable unit skin friction values provided above are based on the strengths of the in-situ soils and utilize a design safety factor of 2 against shear failure. The straight shaft drilled piers should be founded at depths between 10 and 22 feet. If it is essential to minimize movement, the piers should be founded at a minimum depth of 20 feet. The piers will be subject to uplift forces resulting from adhesion of the expansive soils along the perimeter of the shafts. The uplift force can be estimated (in kips) by multiplying the diameter of the pier (in feet) by 18. Soil induced uplift can be resisted utilizing the dead load on the pier and the weight of the pier itself. If additional resistance to uplift is required, the allowable skin friction values below a depth of 15 feet may be utilized in the design. Settlement of a properly designed and constructed straight shaft drilled pier is estimated to be on the order of 1 percent of the shaft diameter of the pier. Straight shaft drilled piers should be spaced no closer than three pier diameters apart measured center to center. Drilled piers at this site should be adequately reinforced with a minimum of 1 percent of the cross-sectional area of the pier shaft throughout the depth of the pier to withstand uplift forces.

K= modulus of subgrade reaction (pci) Eso= 50% strain value Drilled Piers usinq TS-FD-12 The recommendations provided in this section are applicable to straight shaft drilled piers where the designers will utilize the Texas Department of Transportation Traffic Signal Pole Foundation Standard TS-FD-12. This document utilizes the strengths of the soils as determined by the Texas Cone Penetrometer(TCP) Test in blows/ft. Although some variances occurred during sampling based on the driller's judgement, the soils sampled for this project generally utilized Shelby tube samples in cohesive soils (CLAY) and the Standard Penetration Test (SPT) in cohesionless soils (SAND). The SPT tests were converted to TCP using relationships developed by Touma and Reese (1969). The relationship for cohesive and non- cohesive soils are as follows: Cohesionless Soils (SAND) TCP = SPT/0.5 Cohesive Soils (CLAY) TCP = SPT/0.7 In addition, given the undrained shear strength (Su) provided in the soil profile table, the corresponding TCP to use for the range in undrained shear strength of CLAY soils is provided in the following table.

Sunwood Drive to Staples Street, Corpus Christi, Texas RETL Job Number: G121260 MSA No. 3399, Project No. 21063, Task Order No. 6 The calculated approximate equivalent values for the Texas Cone Penetrometer Tests are provided in the Soil Profile Table in the "Subarade Soil Conditions" section of this report. The approximate equivalent calculated TCP values may be utilized for design in conjunction with the Texas Department of Transportation Traffic Signal Pole Foundation Standard TS-FD-12. Straight shaft drilled piers should be spaced no closer than three pier diameters apart measured center to center. Drilled piers at this site should be adequately reinforced with a minimum of 1 percent of the cross-sectional area of the pier shaft throughout the depth of the pier to withstand uplift forces. CONSTRUCTION CONSIDERATIONS Site Drainage Allowances for proper drainage and proper material selection of base materials are most important for performance of pavements. Ruts and areas that hold water in asphalt pavements allow for quick deterioration of the pavement primarily due to saturation of the underlying base materials and subgrade soils. The pavement design recommendations in this report are based on the assumption that the pavements will have good drainage off the surface and away from the edges. A minimum of 2-percent cross slope in the pavement surface is recommended. Drilled, Cast-in-Place, Pier Construction Considerations For drilled piers founded below a depth of approximately 15 feet, temporary steel casing may be required to successfully install the drilled piers in order to maintain a stable excavation and prevent sloughing of soils into the pier excavation prior to pier observation, placement of reinforcing steel and concrete placement. The pier drilling contractor should be prepared and have casing on-site. Drilled piers constructed utilizing temporary steel casing require that concrete be placed as soon as possible after all loose material has been removed, the pier excavation inspected, and reinforcing steel installed. A relatively high slump concrete mix (6 to 7 inches) is suggested to minimize aggregate segregation caused by the reinforcing steel. Free fall of concrete into the pier excavation is permitted provided the concrete can be placed into the pier excavation without striking the sides of the excavation or hitting the rebar. It should be noted that research has shown that free fall concrete guided at the top of the excavation to avoid contact with the sides of the pier excavation and reinforcing steel can drop more than 80 feet without any measurable segregation. In addition, the research has shown that as long as the concrete drop is in air the strength of the concrete was not adversely affected. In situations where it is impossible for the concrete to fall freely without striking the rebar cage or sides of the pier excavation the free fall should be limited to 10 feet, or placed with a tremie. Pier excavations should not be allowed to stay open overnight.

Sunwood Drive to Staples Street, Corpus Christi, Texas RETL Job Number: G121260 MSA No. 3399, Project No. 21063, Task Order No. 6 The successful placement of a pier foundation is dependent on the expertise of the drilled pier foundation contractor. It is recommended that the groundwater elevation at the pier locations be determined at the time of construction to ensure that the proper method of pier installation is being performed. The Geotechnical Engineer, or his designated representative, should be present to witness the test excavations and installation of the drilled piers. Earthwork and Subgrade Acceptance Exposure to the environment may weaken the soils at the pavement bearing levels if the excavations remain open for long periods of time. Therefore, it is recommended that the pavement excavations be extended to final grade and that the pavements be constructed as soon as possible to minimize potential damage to the bearing soils. The pavement bearing level should be free of loose soil, ponded water or debris and should be observed prior to placing pavement constituents by the Geotechnical Engineer, or his designated representative. Pavement constituents should not be placed on soils that have been disturbed by rainfall or seepage. If the bearing soils are softened by surface water intrusion, or by desiccation, the unsuitable soils must be removed from the pavement excavations and be replaced with properly compacted fill or crushed limestone base, as directed by the Geotechnical Engineer, or his designated representative, prior to placement of pavement constituents. The Geotechnical Engineer, or his designated representative, should monitor subgrade preparation and placement of all pavement constituents. As a guideline, a minimum of one, in- place density test should be performed on the subgrade soils and each subsequent lift of base materials at a rate of one test per 200 linear feet of travel lane. Any areas not meeting the required compaction should be recompacted and retested until compliance is met. GENERAL COMMENTS If significant changes are made in the character or location of the proposed project, a consultation should be arranged to review any changes with respect to the prevailing soil conditions. At that time, it may be necessary to submit supplementary recommendations. It is recommended that the services of RETL be engaged to test and evaluate the subgrade soils in the excavations prior to placing pavement constituents or concrete in order to verify that the bearing soils are consistent with those encountered in the borings. RETL cannot accept any responsibility for any conditions that deviate from those described in this report, nor for the performance of the pavement systems or foundations if not engaged to also provide construction observation and testing for this project. If it is required for RETL to accept any liability, then RETL must agree with the plans and perform such observation during construction as we recommend. All sheeting, shoring, and bracing of trenches, pits and excavations should be made the responsibility of the contractor and should comply with all current and applicable local, state and federal safety codes, regulations and practices, including the Occupational Safety and Health Administration.
