There is no corresponding adjustment with respect to other items of Work; and 3. Contractor believes it has incurred additional expense as a result of this condition or Owner believes that the quantity variation entitles Owner to an adjustment in the Contract Price. 15.04 Contingencies A. Contingency funds may be included in the Contract Price to pay for Work not defined specifically by the Contract Documents that is essential to the completion of the Project. Contingency funds will be as described in the Contract. B. The contingency funds may be used for costs incurred by the Contractor provided these costs are approved by the Owner.

Minority/Disadvantaged person(s) must collectively own, operate and/or actively manage, and share in payments from such an enterprise in the manner hereinafter set forth: 1. Owned: a. For a sole proprietorship to be deemed a minority business enterprise, it must be owned by a minority person. b. For an enterprise doing business as a partnership, at least 51 percent of the assets or interest in the partnership property must be owned by one or more minority person(s). General Conditions 00 72 00-102 Corpus Christi Standards Rev 6/2021 C. For an enterprise doing business as a corporation, at least 51 percent of the assets or interest in the corporate shares must be owned by one or more minority person(s). 2. Controlled: a. The primary power, direct or indirect,to manage a business enterprise rests with a minority person(s). 3. Share in Payments: a.

Note: Executive Order(EO) 13706, Establishing Paid Sick Leave for Federal Contractors applies to all contracts subject to the Davis-Bacon Act for which the contract is awarded (and any solicitation was issued) on or after January 1, 2017. If this contract is covered by the EO,the contractor must provide employees with 1 hour of paid sick leave for every 30 hours they work, up to 56 hours of paid sick leave each year. Employees must be permitted to use paid sick leave for their Supplementary Conditions 00 73 00-7 E15101 Harbor Bridge Parks Mitigation Project Rev 3/2023 own illness, injury or other health-related needs, including preventive care;to assist a family member(or person who is like family to the employee)who is ill, injured,or has other health-related needs, including preventive care; or for reasons resulting from, or to assist a family member(or person who is like family to the employee)who is a victim of,domestic violence,sexual assault,or stalking. Additional information on contractor requirements and worker protections under the EO is available at https://www.dol.gov/agencies/whd/government-contracts. Unlisted classifications needed for work not included within the scope of the classifications listed may be added after award only as provided in the labor standards contract clauses (29CFR 5.5 (a) (1) (iii)). ---------------------------------------------------------------- The body of each wage determination lists the classification and wage rates that have been found to be prevailing for the cited type(s) of construction in the area covered by the wage determination.The classifications are listed in alphabetical order of""identifiers"" that indicate whether the particular rate is a union rate(current union negotiated rate for local), a survey rate(weighted average rate)or a union average rate (weighted union average rate). Union Rate Identifiers A four letter classification abbreviation identifier enclosed in dotted lines beginning with characters other than "SU"" or Supplementary Conditions 00 73 00-8 E15101 Harbor Bridge Parks Mitigation Project Rev 3/2023 ""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(C13A)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. As this weighted average rate includes all rates reported in the survey, it may include both union and non-union rates. Example:SULA2012-007 5/13/2014.SU indicates the rates are survey rates based on a weighted average calculation of rates and are not majority rates. LA indicates the State of Louisiana. 2012 is the year of survey on which these classifications and rates are based.The next number,007 in the example,is an internal number used in producing the wage determination. 5/13/2014 indicates the survey completion date for the classifications and rates under that identifier. Supplementary Conditions 00 73 00-9 E15101 Harbor Bridge Parks Mitigation Project Rev 3/2023 Survey wage rates are not updated and remain in effect until a new survey is conducted. Union Average Rate Identifiers Classification(s) listed under the UAVG identifier indicate that no single majority rate prevailed for those classifications; however, 100%of the data reported for the classifications was union data. EXAMPLE: UAVG-OH-0010 08/29/2014. UAVG indicates that the rate is a weighted union average rate.OH indicates the state.The next number,0010 in the example, is an internal number used in producing the wage determination.08/29/2014 indicates the survey completion date for the classifications and rates under that identifier. A UAVG rate will be updated once a year, usually in January of each year,to reflect a weighted average of the current negotiated/CBA rate of the union locals from which the rate is based. ---------------------------------------------------------------- WAGE DETERMINATION APPEALS PROCESS 1.) Has there been an initial decision in the matter?This can be: * an existing published wage determination * a survey underlying a wage determination * a Wage and Hour Division letter setting forth a position on a wage determination matter Supplementary Conditions 00 73 00- 10 E15101 Harbor Bridge Parks Mitigation Project Rev 3/2023 * a conformance(additional classification and rate) ruling On survey related matters, initial contact, including requests for summaries of surveys,should be with the Wage and Hour National Office because National Office has responsibility for the Davis-Bacon survey program. If the response from this initial contact is not satisfactory,then the process described in 2.)and 3.)should be followed. With regard to any other matter not yet ripe for the formal process described here, initial contact should be with the Branch of Construction Wage Determinations. Write to: Branch of Construction Wage Determinations Wage and Hour Division U.S. Department of Labor 200 Constitution Avenue, N.W. Washington, DC 20210 2.) If the answer to the question in 1.) is yes,then an interested party(those affected by the action) can request review and reconsideration from the Wage and Hour Administrator (See 29 CFR Part 1.8 and 29 CFR Part 7).Write to: Wage and Hour Administrator U.S. Department of Labor 200 Constitution Avenue, N.W. Washington, DC 20210 The request should be accompanied by a full statement of the interested party's position and by any information (wage payment data, project description,area practice material, etc.)that the requestor considers relevant to the issue. Supplementary Conditions 00 73 00- 11 E15101 Harbor Bridge Parks Mitigation Project Rev 3/2023 3.) If the decision of the Administrator is not favorable,an interested party may appeal directly to the Administrative Review Board (formerly the Wage Appeals Board). Write to: Administrative Review Board U.S. Department of Labor 200 Constitution Avenue, N.W.

Please see the Note at the top of the wage determination for more information. Please also note that the minimum wage requirements of Executive Order 14026 are not currently being enforced as to any contract or subcontract to which the states of Texas, Louisiana,or Mississippi, including their agencies,are a party. Note: Executive Order(EO) 13706, Establishing Paid Sick Leave for Federal Contractors applies to all contracts subject to the Davis-Bacon Act for which the contract is awarded (and any solicitation was issued) on or after January 1, 2017. If this contract is covered by the EO,the contractor must provide employees with 1 hour of paid sick leave for every 30 hours they work, up to 56 hours of paid sick leave each year. Employees must be permitted to use paid sick leave for their own illness, injury or other health-related needs, including preventive care;to assist a family member(or person who is like family to the employee)who is ill, injured,or has other health-related needs, including preventive care; or for reasons resulting from, or to assist a family member(or person who is like family to the employee)who is a victim of,domestic violence,sexual assault,or stalking. Additional information on contractor requirements and worker protections under the EO is available at https://www.dol.gov/agencies/whd/government-contracts. Unlisted classifications needed for work not included within the scope of the classifications listed may be added after award only as provided in the labor standards contract clauses (29CFR 5.5 (a) (1) (iii)). Supplementary Conditions 00 73 00- 18 E15101 Harbor Bridge Parks Mitigation Project Rev 3/2023 ---------------------------------------------------------------- The body of each wage determination lists the classification and wage rates that have been found to be prevailing for the cited type(s) of construction in the area covered by the wage determination.The classifications are listed in alphabetical order of""identifiers"" that indicate whether the particular rate is a union rate(current union negotiated rate for local), a survey rate(weighted average rate)or a union average rate (weighted union average rate). 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. Supplementary Conditions 00 73 00- 19 E15101 Harbor Bridge Parks Mitigation Project Rev 3/2023 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. As this weighted average rate includes all rates reported in the survey, it may include both union and non-union rates. Example:SULA2012-007 5/13/2014.SU indicates the rates are survey rates based on a weighted average calculation of rates and are not majority rates. LA indicates the State of Louisiana. 2012 is the year of survey on which these classifications and rates are based.The next number,007 in the example,is an internal number used in producing the wage determination. 5/13/2014 indicates the survey completion date for the classifications and rates under that identifier. Survey wage rates are not updated and remain in effect until a new survey is conducted. Union Average Rate Identifiers Classification(s) listed under the UAVG identifier indicate that no single majority rate prevailed for those classifications; however, 100%of the data reported for the classifications was union data. EXAMPLE: UAVG-OH-0010 08/29/2014. UAVG indicates that the rate is a weighted union average rate.OH indicates the state.The next number,0010 in the example, is an internal number used in producing the wage determination.08/29/2014 indicates the survey completion date for the classifications and rates under that identifier. Supplementary Conditions 00 73 00-20 E15101 Harbor Bridge Parks Mitigation Project Rev 3/2023 A UAVG rate will be updated once a year, usually in January of each year,to reflect a weighted average of the current negotiated/CBA rate of the union locals from which the rate is based. ---------------------------------------------------------------- WAGE DETERMINATION APPEALS PROCESS 1.) Has there been an initial decision in the matter?This can be: * an existing published wage determination * a survey underlying a wage determination * a Wage and Hour Division letter setting forth a position on a wage determination matter * a conformance(additional classification and rate) ruling On survey related matters, initial contact, including requests for summaries of surveys,should be with the Wage and Hour National Office because National Office has responsibility for the Davis-Bacon survey program.

Unless specified otherwise on the drawings, the existing surface shall be loosened by scarifying or plowing to a depth of not less than six (6)inches. The loosened material shall be recompacted with fill required to bring the site to the required grades and elevations indicated on the plans. Fill shall be uniform as to material, density and moisture content. Fill shall be free of large clods, large rocks, organic matter, and other objectionable material. No fill that is placed by dumping in a pile or windrow shall be incorporated into a layer in that position; all such piles and windrows shall be moved by blading or similar method. All fill shall be placed in layers approximately parallel to the finish grade in layers not to exceed six (6) inches of uncompacted depth, unless indicated otherwise on drawings. The fill shall be compacted to a density which approximates that of natural ground unless indicated otherwise on drawings. The Engineer may order proof rolling to test the uniformity of compaction. All irregularities, depressions and soft spots that develop shall be corrected by the Contractor. Excess material from excavation, which is not incorporated into the site as fill, shall be become property of the Contractor and disposed of away from the job site, unless indicated otherwise on the drawings. 3. MEASUREMENT AND PAYMENT Unless otherwise specified on the Bid Form, site grading shall not be measured for pay, but shall be considered subsidiary to other work. 021040 Page 1 of 1 Rev.10-30-2014 SECTION 021080 REMOVING ABANDONED STRUCTURES 1. DESCRIPTION This specification shall provide for the demolition,removal and disposal of abandoned structures or portions of abandoned structures, as noted on the drawings, and shall include all excavation and backfilling necessary to complete the removal. The work shall be done in accordance with the provisions of these specifications. 2. METHOD OF REMOVAL Culverts or Sewers. Pipe shall be removed by careful excavation of all dirt on top and the sides in such manner that the pipe will not be damaged. Removal of sewer appurtenances shall be included for removal with the pipe. Those pipes which are deemed unsatisfactory for reuse by the Engineer may be removed in any manner the Contractor may select. Concrete Structures. Unwanted concrete structures or concrete portions of structures shall be removed to the lines and dimensions shown on the drawings, and these materials shall be disposed of as shown on the drawings or as directed by the Engineer. Any portion of the existing structure outside of the limits designated for removal which is damaged by the Contractor's operations shall be restored to its original condition at the Contractor's entire expense. Explosives shall not be used in the removal of portions of the existing structure unless approved by the Engineer, in writing. Portions of the abandoned structure shall be removed to the lines and dimensions shown on the plans, and these materials shall be disposed of as shown on the drawings or as directed by the Engineer. Any portion of the existing structure, outside of the limits designated for removal, damaged during the operations of the Contractor, shall be restored to its original condition entirely at the Contractor's expense. Explosives shall not be used in the removal of portions of the existing structure unless approved by the Engineer, in writing. Concrete portions of structures below the permanent ground line, which will not interfere in any manner with the proposed construction, may be left in place, but removal shall be carried at least five (5) feet below the pennanent ground line and neatly squared off. Reinforcement shall be cut off close to the concrete. Steel Structures. Steel structures or steel portions of structures shall be dismantled in sections as determined by the Engineer. The sections shall be stored if the members are to be salvaged and reused. Rivets and bolts connecting steel railing members, steel beams of beam spans and steel stringers of truss spans, shall be removed by butting the heads with a "cold cut" and punching or drilling from the hole, or by such other method that will not injure the members for re-use and will meet the approval of the Engineer. The removal of rivets and bolts from connections of truss 021080 Page 1 of 3 Rev.10-30-2014 members, bracing members, and other similar members in the structure will not be required unless specifically called for on the plans or special provisions, and the Contractor shall have the option of dismantling these members by flame-cutting the members innnediately adjacent to the connections. Flame-cutting will not be permitted, however, when the plans or special provisions call for the structure unit to be salvaged in such manner as to permit re-erection. In such case, all members shall be carefully matchmarked with paint in accordance with diagrams furnished by the Engineer prior to dismantling, and all rivets and bolts shall be removed from the connections in the manner specified in the first portion of this paragraph. Timber Structures. Timber structures or timber portions of structures to be reused shall be removed in such manner as to damage the timber for further use as little as possible. All bolts and nails shall be removed from such lumber as deemed salvable by the Engineer. Unless otherwise specified on the drawings,timber piles shall be either pulled or cut off at the point not less than five (5) feet below ground line, with the choice between these two methods resting with the Contractor,unless otherwise specified. Brick or Stone Structures. Unwanted brick or stone structures or stone portions of structures shall be removed. Portions of such structures below the permanent ground line, which will not in any manner interfere with the proposed construction, may be left in place, but removal shall be carried at least five (5) feet below the permanent ground line and neatly squared off. Salvage. All material such as pipe, timbers, railings, etc., which the Engineer deems as salvable for reuse, and all salvaged structural steel, shall be delivered to a designated storage area. Materials, other than structural steel, which are not deemed salvable by the Engineer, shall become the property of the Contractor and shall be removed to suitable disposal sites off of the right-of-way arranged for by the Contractor, or otherwise disposed of in a manner satisfactory to the Engineer. Where temporary structures are necessary for a detour adjacent to the present structure, the Contractor will be permitted to use the material in the old structure for the detour structure, but he shall dismantle and stack or dispose of the material as required above as soon as the new structure is opened for traffic. Backfill. All excavations made in connection with this specification and all openings below the natural ground line caused by the removal of abandoned structures or portions thereof shall be backfilled to the level of the original ground line, unless otherwise provided on the drawings. Backfill in accordance with applicable requirements of Sections 022020 "Excavation and Backfill for Utilities" and 022080 "Embankment". All open ends of abandoned pipe or other structures shall be filled or plugged as specified. That portion of the backfill which will support any portion of the roadbed, embankment, levee, or other structural feature shall be placed in layers of the same depth as those required for placing 021080 Page 2 of 3 Rev.10-30-2014 embankment, maximum 10" loose lifts unless otherwise specified. Material in each layer shall be wetted uniformly, if required, and shall be compacted to a minimum of 95% Standard Proctor density, unless otherwise specified. In places inaccessible to blading and rolling equipment, mechanical or hand tamps or rammers shall be used to obtain the required compaction. That portion of the backfill which will not support any portion of the roadbed, embankment, or other structural feature shall be placed as directed by the Engineer in such manner and to such state of compaction as will preclude objectionable amount of settlement, maximum 10" loose lifts to minimum 95% Standard Proctor density unless otherwise specified. 3. MEASUREMENT AND PAYMENT Unless otherwise specified on the Bid Form, the work governed by this specification shall not be measured for pay, but shall be subsidiary to the project. 021080 Page 3 of 3 Rev.10-30-2014 SECTION 022020 EXCAVATION AND BACKFILL FOR UTILITIES 1. 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 (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 (8) Backfill A. Backfill Procedure Around Pipe (Initial Backfill) All trenches and excavation shall be backfilled as soon as is practical after the pipes or conduits are properly laid. In addition to the specified pipe bedding material, the backfill around the pipe as applicable shall be granular material as shown on the standard details or as described in the applicable specification section, and shall be free of large hard lumps or other debris. If indicated on the plans, pipe shall be encased with cement-stabilized sand backfill as described below. The backfill shall be deposited in the trench simultaneously on both sides of the pipe for the full width of the trench,in layers not to exceed ten(10)inches (loose measurement), wetted if required to obtain proper compaction, and thoroughly compacted by use of mechanical tampers to a density comparable to the adjacent undisturbed soil or as otherwise specified on the plans,but not less than 95%Standard Proctor density. A thoroughly compacted material shall be in place between the external wall of the pipe and the undisturbed sides of the trench and to a level twelve (12) inches above the top of the pipe. B. Backfill Over One Foot Above Pipe (Final Backfill) UNPAVED AREAS: The backfill for that portion of trench over one(1)foot above the pipe or conduit not located under pavements (including waterlines, gravity wastewater lines, wastewater force mains and reinforced concrete storm water pipe) shall be imported select material or clean, excess material from the excavation meeting the following requirements: Free of hard lumps, rock fragments, or other debris, No clay lumps greater than 2" diameter Moisture Content: +/-3% Backfill material shall be placed in layers not more than ten (10) inches in depth (loose measurement),wetted if required to obtain proper compaction,and thoroughly compacted by use of mechanical tampers to the natural bank density but not less than 95%Standard Proctor density,unless otherwise indicated. Flooding of backfill is not allowed. Jetting of backfill may only be allowed in sandy soils and in soils otherwise approved by the Engineer. Regardless of backfill method, no lift shall exceed 10 inches and density shall not be less than 95% Standard Proctor density. A period of not less than twenty-four (24)hours shall elapse between the time of jetting and the placing of the top four (4) feet of backfill. If jetting is used, the top four (4) feet of backfill shall be placed in layers not more than 10 inches in depth (loose measurement), wetted if required to obtain proper compaction, and thoroughly compacted by use of mechanical tampers to the natural bank density but not less than 95% Standard Proctor density (ASTM D698). PAVED AREAS: At utility line crossings under pavements (including waterlines, gravity wastewater lines, wastewater force mains, and reinforced concrete storm water pipe), and where otherwise indicated on the drawings, trenches shall be backfilled as shown below: From top of initial backfill (typically twelve (12)inches above top of the pipe)to three (3) feet below bottom of road base course, backfill shall be select material meeting the requirements of 022100 "Select Material". 022020 Page 3 of 4 Rev.3-25-2015 Asphalt Roadway The upper three (3) feet of trench below the road base course shall be backfilled to the bottom of the road base course with cement-stabilized sand containing a minimum of 2 sacks of Standard Type I Portland cement per cubic yard of sand and compacted to not less than 95% Standard Proctor density. Concrete Roadways The Contractor may elect to backfill the upper three (3) feet of trench below the road base course with cement stabilized sand as noted above, or in the case of storm water pipe or box installation the Contractor may backfill and compact select material to 98% Standard Proctor density(ASTM D698) following City Standard Specification Section 022100. 3. MEASUREMENT AND PAYMENT Unless otherwise specified on the Bid Form, excavation and backfill for utilities, including select material or cement-stabilized sand backfill, shall not be measured and paid for separately. It shall be considered subsidiary to the items for which the excavation and backfill is required. 022020 Page 4 of 4 Rev.3-25-2015 SECTION 022021 CONTROL OF GROUND WATER 1.

Dewatering includes lowering the water table and intercepting seepage which would otherwise emerge from slopes or bottoms of excavations, or into tunnels and shafts, and disposing of removed ground water by approved methods. The intent of dewatering is to increase the stability of tunnel excavations and excavated slopes; prevent dislocation of material from slopes or bottoms of excavations; reduce lateral loads on sheeting and bracing; improve excavating and hauling characteristics of excavated material;prevent failure or heaving of the bottom of excavations; and to provide suitable conditions for placement of backfill materials and construction of structures,piping and other installations. 2. Depressurization includes reduction in piezometric pressure within strata not controlled by dewatering alone, as required to prevent failure or heaving of excavation bottom or instability of tunnel excavations. B. Excavation drainage includes keeping excavations free of surface and seepage water. 022021 Page 1 of 10 Rev.10-30-2014 C. Surface drainage includes the use of temporary drainage ditches and dikes and installation of temporary culverts and sump pumps with discharge lines as required to protect the Work from any source of surface water. D. Equipment and instrumentation for monitoring and control of the ground water control system includes piezometers and monitoring wells, and devices, such as flow meters, for observing and recording flow rates. 1.4 PERFORMANCE REQUIREMENTS A. Conduct subsurface investigations as needed to identify ground water conditions and to provide parameters for design, installation, and operation of ground water control systems. B. Design a ground water control system, compatible with requirements of Federal Regulations 29 CFR Part 1926 and City Standard Specification Section 022022 - Trench Safety for Excavations, to produce the following results: l. Effectively reduce the hydrostatic pressure affecting: a) Excavations (including utility trenches); b) Tunnel excavation, face stability or seepage into tunnels. 2. Develop a substantially dry and stable subgrade for subsequent construction operations. 3.

Provide ground water control systems which may include single-stage or multiple-stage well point systems, eductor and ejector-type systems, deep wells, or combinations of these equipment types. D. Provide drainage of seepage water and surface water, as well as water from any other source entering the excavation. Excavation drainage may include placement of drainage materials, such as crushed stone and filter fabric, together with sump pumping. E. Provide ditches, berms, pumps and other methods necessary to divert and drain surface water away from excavations. F. Locate ground water control and drainage systems so as not to interfere with utilities, construction operations, adjacent properties, or adjacent water wells. 022021 Page 2 of 10 Rev.10-30-2014 G. Assume sole responsibility for ground water control systems and for any loss or damage resulting from partial or complete failure of protective measures, and any settlement or resultant damage caused by the ground water control operations. Modify ground water control systems or operations if they cause or threaten to cause damage to new construction, existing site improvements, adjacent property, or adjacent water wells, or affect potentially contaminated areas. Repair damage caused by ground water control systems or resulting from failure of the system to protect property as required. H. Provide an adequate number of piezometers installed at the proper locations and depths as required to provide meaningful observations of the conditions affecting the excavation, adjacent structures, and water wells. I. Provide environmental monitoring wells installed at the proper locations and depths as required to provide adequate observations of hydrostatic conditions and possible contaminant transport from contamination sources into the work area or into the ground water control system. J. Decommission piezometers and monitoring wells installed during design phase studies and left for Contractors monitoring and use, if applicable. 1.5 ENVIRONMENTAL REQUIREMENTS A. Comply with requirements of agencies having jurisdiction. B. Comply with Texas Commission on Environmental Quality(TCEQ)regulations and Texas Water Well Drillers Association for development, drilling, and abandonment of wells used in dewatering system. C. Prior to beginning construction activities, file Notice of Intent (NOI) for Storm Water Discharges Associated with Construction Activity under the Texas Pollutant Elimination System (TPDES) General Permit No. TXR150000, administered by the Texas Commission on Environmental Quality(TCEQ). The general permit falls under the provisions of Section 402 of the Clean Water Act and Chapter 26 of the Texas Water Code. D. Prepare submittal form and submit to TCEQ along with application fee. E. Upon completion of construction, file Notice of Termination (NOT) for Storm Water Discharges Associated with Construction Activity under the TPDES General Permit with the TCEQ. F. Obtain all necessary permits from agencies with control over the use of ground water and matters affecting well installation, water discharge, and use of existing storm drains and natural water sources. Because the review and permitting process may be lengthy, take early action to pursue and submit for the required approvals. G. Monitor ground water discharge for contamination while performing pumping in the vicinity of potentially contaminated sites. 022021 Page 3 of 10 Rev.10-30-2014 H. Conduct sampling and testing of ground water and receiving waters as outlined in Article 3 below. 2. PRODUCTS 2.1 EQUIPMENT AND MATERIALS A.

Arrange for appropriate backup if electrical power is primary energy source for dewatering system. E. Monitor operations to verify that the system lowers ground water piezometric levels at a rate required to maintain a dry excavation resulting in a stable subgrade for prosecution of subsequent operations. F. Where hydrostatic pressures in confined water bearing layers exist below excavation, depressurize those zones to eliminate risk of uplift or other instability of excavation or installed 022021 Page 4 of 10 Rev.10-30-2014 works. Allowable piezometric elevations shall be defined in the ground water control system design. G. Remove ground water control installations. 1. Remove pumping system components and piping when ground water control is no longer required. 2. Remove piezometers and monitoring wells when directed by the City Engineer. 3. Grout abandoned well and piezometer holes. Fill piping that is not removed with cement- bentonite grout or cement-sand grout. H. During backfilling, dewatering may be reduced to maintain water level a minimum of 5 feet below prevailing level of backfill. However, do not allow that water level to result in uplift pressures in excess of 80 percent of downward pressure produced by weight of structure or backfill in place. Do not allow water levels to rise into cement stabilized sand until at least 48 hour after placement. I. Provide a uniform diameter for each pipe drain run constructed for dewatering. Remove pipe drain when it has served its purpose. If removal of pipe is impractical, provide grout connections at 50-foot intervals and fill pipe with cement-bentonite grout or cement-sand grout when pipe is removed from service. J. Extent of construction ground water control for structures with a permanent perforated underground drainage system may be reduced, such as for units designed to withstand hydrostatic uplift pressure. Provide a means for draining the affected portion of underground system, including standby equipment. Maintain drainage system during operations and remove it when no longer required. K. Remove system upon completion of construction or when dewatering and control of surface or ground water is no longer required. L. In unpaved areas, compact backfill to not less than 95 percent of Standard Proctor maximum dry density in accordance with ASTM D 698. In paved areas (or areas to receive paving), compact backfill to not less than 98 percent of Standard Proctor maximum dry density in accordance with ASTM D 698. 3.2 REQUIREMENTS FOR EDUCTOR, WELL POINTS, OR DEEP WELLS A. For above ground piping in ground water control system, include a 12-inch minimum length of clear, transparent piping between every eductor well or well point and discharge header so that discharge from each installation can be visually monitored. B. Install sufficient piezometers or monitoring wells to show that all trench or shaft excavations in water bearing materials are pre-drained prior to excavation. Provide separate piezometers for 022021 Page 5 of 10 Rev.10-30-2014 monitoring of dewatering and for monitoring of depressurization. Install piezometers and monitoring wells for tunneling as appropriate for Contractor's selected method of work. C. Install piezometers or monitoring wells not less than one week in advance of beginning the associated excavation (including trenching). D. Dewatering may be omitted for portions of underdrains or other excavations, but only where auger borings and piezometers or monitoring wells show that soil is pre-drained by an existing system such that the criteria of the ground water control system design are satisfied. E. Replace installations that produce noticeable amounts of sediments after development. F. Provide additional ground water control installations, or change the methods, in the event that the installations according to the ground water control system design do not provide satisfactory results based on the performance criteria defined by the ground water control system design and by these specifications. 3.3 EXCAVATION DRAINAGE A. Contractor may use excavation drainage methods if necessary to achieve well drained conditions. The excavation drainage may consist of a layer of crushed stone and filter fabric, and sump pumping in combination with sufficient wells for ground water control to maintain stable excavation and backfill conditions. 3.4 MAINTENANCE AND OBSERVATION A. Conduct daily maintenance and observation of piezometers or monitoring wells while the ground water control installations or excavation drainage are operating in an area or seepage into tunnel is occurring. Keep system in good condition. B. Replace damaged and destroyed piezometers or monitoring wells with new piezometers or wells as necessary to meet observation schedule. C. Cut off piezometers or monitoring wells in excavation areas where piping is exposed, only as necessary to perform observation as excavation proceeds. Continue to maintain and make observations, as specified. D. Remove and grout piezometers inside or outside the excavation area when ground water control operations are complete. Remove and grout monitoring wells when directed by the City Engineer. 3.5 MONITORING AND RECORDING 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 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 storin 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 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 mg/L Total Lead Initial +Weekly 0.1 m /L Benzene Initial +Weekly 0.005 m /L Total BTEX Initial +Weekly 0.1 m /L Polynuclear Aromatic Hydrocarbons I 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 storin 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 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.

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 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 immediately 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 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 lime 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. Mixing- 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 111) — 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 Table 1 Gradation Re uirements (Minimum % Passing) Sieve Size Base Sub grade 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 1/2" 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 5. MEASUREMENT AND PAYMENT Unless otherwise specified on the Bid Form, lime stabilization for bases, sub-bases and subgrade shall be measured by the square yard of lime-stabilized material in place. Pulverizing, mixing, watering grading, compacting, working material etc., shall not be measured for pay but shall be subsidiary to other work. Payment shall be full compensation for all materials, labor, equipment, tools, and incidentals necessary for the completion of work. 025210 Page 4 of 4 Rev.9-2-2020 SECTION 025223 CRUSHED LIMESTONE FLEXIBLE BASE 1.

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/M&P and in effect at the time of testing and will be billed directly to the Contractor or supplier. TEXAS DEPARTMENT OF TRANSPORTATION 1-7 EFFECTIVE DATE:JANUARY 2010 DEPARTMENTAL MATERIALS SPECIFICATION PAVEMENT MARKERS(REFLECTORIZED) A. Pre-Qualification Request. Prospective suppliers interested in submitting their product for evaluation must submit a written request to the Texas Department of Transportation, Construction Division, Materials & Pavements Section (CP51), 125 East llth Street, Austin, TX 78701-2483. Include the following items with the request: • Name and contact information, including email address for the person who will be the primary contact during the qualification process; • Laboratory test results, from the manufacturer's lab or an independent test laboratory, showing actual test results that meet the requirements of ASTM D 4280; • Product data sheets; • List of locations and applications dates where the product is being evaluated or is in current use; and • Test results from the National Transportation Product Evaluation Program(NTPEP), if available. B. Laboratory Testing. Provide CST/M&P with 350 RPMs of each color and type for laboratory and field testing. Submit materials for laboratory testing and field evaluations at no cost to the Department. CST/M&P will acknowledge receipt of materials and specify a tentative completion date for laboratory testing. CST/M&P will test RPMs in accordance with Article 4200.6 and will send notification of results once laboratory testing is complete. If laboratory testing conducted by TxDOT or by NTPEP shows RPMs do not meet the requirements of this specification, evaluation will cease, and RPMs will not be qualified. Suppliers may resubmit materials for qualification after providing documentation identifying the cause and corrective action taken. C. Field Testing. Upon satisfactory completion of laboratory testing, CST/M&P will specify the location of one or more roadways selected for the 12-month field test and suggested application dates. The roadways will include: • a concrete surface, • a hot-mix asphalt surface, and • a Grade 3 sealcoat. The concrete and asphalt roadways will be full-access controlled freeways with a minimum average daily traffic (ADT) count of 35,000 vehicles, a minimum of 20% average daily truck traffic volume, and a minimum posted speed limit of 65 mph. The Grade 3 road test will be conducted on a four-lane divided highway with a minimum ADT count of 4,000 vehicles per lane, a minimum of 20% average daily truck traffic volume, and a minimum posted speed limit of 50 mph. Providing NTPEP test results meeting the requirements of this specification may replace the concrete and hot-mix asphalt field tests on a deck for deck basis. If TxDOT or NTPEP field testing shows RPMs do not meet the requirements of this specification, evaluation will cease, and RPMs will not be qualified. Suppliers may TEXAS DEPARTMENT OF TRANSPORTATION 2-7 EFFECTIVE DATE:JANUARY 2010 DEPARTMENTAL MATERIALS SPECIFICATION PAVEMENT MARKERS(REFLECTORIZED) resubmit materials for qualification after providing documentation identifying the cause and corrective action taken. 1. 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 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. Functionality.Four RPMs placed at 80 foot spacing or eight RPMs placed at 40 foot spacing must be functional when viewed at night from a vehicle using the low beam headlight setting. 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. TEXAS DEPARTMENT OF TRANSPORTATION 4-7 EFFECTIVE DATE:JANUARY 2010 DEPARTMENTAL MATERIALS SPECIFICATION PAVEMENT MARKERS(REFLECTORIZED) 2. Failure. CST/M&P will revolve provisional qualification for RPMs that do not meet the performance criteria and will remove the RPMs from the MPL. Producers not qualified under this Specification may not furnish materials for Department projects and must show evidence of correction of all deficiencies before reconsideration for qualification. F. Periodic Evaluation.Periodic evaluation consists of random department-initiated laboratory testing, audits, and periodic required submittals or field testing. 1. Department-Initiated Laboratory Testing and Audits. The Department may conduct random sampling (per Tex-729-I) and testing on pre-qualified RPMs to identify changes in the material or nonconformity in production and to perform random audits of test reports. 2. Required Submittals or Field Testing. Every 5 years,provide NTPEP data showing continued compliance with the requirements of this specification. G. Disqualification. Causes for disqualification and removal from the MPL include, but are not limited to, the following: • material fails to meet the requirements stated in this specification; • the producer fails to report changes in the composition, manufacturing process, or design to CST/M&P; • the producer has unpaid charges for failing samples; or • qualified RPMs demonstrate repeated and large-scale performance problems in the field. H. Re-Qualification. Suppliers disqualified and removed from the MPL may submit materials for requalification after submitting documentation identifying the cause of the problem and corrective action taken. 4200.6.

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 (I-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. Add 50 mL (1.7 fl. oz.) of trichloroethylene to the adhesive. Swirl or stir the mixture with a fine rod, taping care not TEXAS DEPARTMENT OF TRANSPORTATION 2-3 LAST REVIEWED:SEPTEMBER 2014 DEPARTMENTAL MATERIALS SPECIFICATION BITUMINOUS ADHESIVE FOR PAVEMENT MARKERS to lose any solids. 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, taping 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 ± YC (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.

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 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'-1Ito 1'-I" 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 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 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 SECTION 027602 GRAVITY WASTEWATER LINES 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 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-Passing 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 confonning 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 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 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.

(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 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.

(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 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 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 TABLE 3 Slump Requirements Concrete Designation Desired Slump Max. Slump Structural Concrete: (1) Thin-Walled Sections (9" or less) 4 inches 5 inches (2) Slabs, Caps, Columns,Piers, Wall Sections over 9", etc. 3 inches 4 inches Underwater or Seal Concrete 5 inches 6 inches Riprap, Curb, Gutter and Other Miscellaneous Concrete 2.5 inches 4 inches NOTE: No concrete will be permitted with slump in excess of the maximums shown. 8. 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.

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 performing 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 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. After all the ingredients are assembled in the drum, the mixing shall continue not less than 1 minute for mixers of one cubic yard or less capacity plus 15 seconds for each additional cubic yard or portion thereof. The mixer shall operate at the speed and capacity designated by the Mixer Manufacturers Bureau of the Associated General Contractors of America. The mixer shall have a plate affixed showing the manufacturer's recommended operating data. The absolute volume of the concrete batch shall not exceed the rated capacity of the mixer. The entire contents of the drum shall be discharged before any materials are placed therein for the succeeding batch. The first batch of concrete materials placed in the mixer for each placement shall contain an extra quantity of sand, cement and water sufficient to coat the inside surface of the drum. Upon the cessation of mixing for any considerable length of time, the mixer shall be thoroughly cleaned. The concrete mixer shall be equipped with an automatic timing device which is put into operation when the skip is raised to its full height and dumping. This device shall lock the discharging mechanism and prevent emptying of the mixer until all the materials have been mixed together for the minimum time required, and it shall ring a bell after the specified time of mixing has elapsed. The water tank shall be arranged so that the amount of water can be measured accurately, and when the tank starts to discharge, the inlet supply shall cut off automatically. Whenever a concrete mixer is not adequate or suitable for the work, it shall be removed from the site upon a written order from the Engineer and a suitable mixer provided by the Contractor. Pick-up and thro-over blades in the drum of the mixer which are worn down more than 10 percent in depth shall be repaired or replaced with new blades. Improperly mixed concrete shall not be placed in the structure. Job mix concrete shall be concrete mixed in an approved batch mixer in accordance with the requirements stated above, adjacent to the structure for which the concrete is being mixed, and moved to the placement site in non-agitating equipment. 11. READY-MIX PLANTS A. General. It shall be the Contractor's responsibility to furnish concrete meeting all requirement of the governing specification sections, and concrete not meeting the slump, workability and consistency requirements of the governing specification sections shall not 030020 Page 10 of 13 Rev.10-30-2014 be placed in the structure or pavement. Ready-Mixed Concrete shall be mixed and delivered by means of one of the following approved methods.

(Central-Mix Concrete) (2) Mixed complete in a truck mixer and transported to the placement site at mixing and/or agitating speed (Transit-Mix Concrete), subject to the following provisions: (a) Truck mixers will be permitted to transport concrete to the job site at mixing speed if equipped with double actuated counters which will separate revolutions at mixing speed from total revolutions. (b) Truck mixers equipped with a single actuated counter counting total revolutions of the drum shall mix the concrete at the plant not less than 50 nor more than 70 revolutions at mixing speed, transport it to the job site at agitating speed and complete the required mixing before placing the concrete. (3) Mixed completely in a stationery mixer and transported to the job site in approved non-agitating trucks with special bodies. This method of transporting will be permitted for concrete pavement only. B. Equipment. (1) Batching Plant. The batching plant shall be provided with adequate bins for batching all aggregates and materials required by the specifications. Bulk cement shall be weighed on a scale separate from those used for other materials and in a hopper entirely free and independent of that used for weighing the aggregates. (2) Mixers and Agitators. (a) General: Mixers shall be of an approved stationary or truck-type capable of combining the ingredients into a thoroughly mixed and uniform mass. Facilities shall be provided to permit ready access to the inside of the drum for inspection, cleaning and repair of blades. Mixers and agitators shall be subject to daily examination for changes in condition due to accumulation of hardened concrete and/or wear of blades, and any hardened concrete shall be removed before the mixer will be permitted to be used. Worn blades shall be repaired or replaced with new in 030020 Page 11 of 13 Rev.10-30-2014 accordance with the manufacturer's design and arrangement for that particular unit when any part or section is worn as much as 10 percent below the original height of the manufacturer's design. (b) Stationary Mixers: These shall conform to the requirements of Article "Mixing and Mixing Equipment". Truck mixers mounted on a stationary base will not be considered as a stationary mixer. (c) Truck Mixers: In addition, truck mixers shall comply with the following requirements: An engine in satisfactory working condition and capable of accurately gauging the desired speed of rotation shall be mounted as an integral part of the mixing unit for the purpose of rotating the drum. Truck mixers equipped with a transmission that will govern the speed of the drum within the specified revolutions per minute (rpm)will not require a separate engine. All truck mixers shall be equipped with actuated counters by which the proper number of revolutions of the drum, as specified in Article 11. A. above, may be readily verified. The counters shall be read and recorded at the start of mixing at mixing speeds. Each until shall have adequate water supply and accurate metering or gauging devices for measuring the amount used. (d) Agitators: Concrete agitators shall be of the truck type, capable of maintaining a thoroughly mixed and uniform concrete mass and discharging it within the same degree of uniformity specified for mixers. Agitators shall comply with all of the requirements for truck mixers, except for the actual mixing requirements. C. Operation of Plant and Equipment. Delivery of ready-mixed concrete shall equal or exceed the rate approved by the Engineer for continuous placement. In all cases, the delivery of concrete to the placement site shall assure compliance with the time limits in the applicable specification for depositing successive batches in any monolithic unit. The Contractor shall satisfy the Engineer that adequate standby trucks are available. A standard ticket system will be used for recording concrete batching,mixing and delivery date. Tickets will be delivered to the job inspector. Loads arriving without ticket and/or in unsatisfactory condition shall not be used. When a stationary mixer is used for the entire mixing operation, the mixing time for one cubic yard of concrete shall be one minute plus 15 seconds for each additional cubic yard or portion thereof This mixing time shall start when all cement, aggregates and initial water have entered the drum. 030020 Page 12 of 13 Rev.10-30-2014 The mixer shall be charged so that some of the mixing water will enter the drum in advance of the cement and aggregate. All of the mixing water shall be in the drum by the end of the first one- fourth of the specified mixing time. Water used to flush down the blades after charging shall be accurately measured and included in the quantity of mixing water. The introduction of the initial mixing water, except blade wash down water and that permitted in this Article, shall be prior to or simultaneous with the charging of the aggregates and cement. The loading of truck mixers shall not exceed 63 percent of the total volume of the drum. When used as an agitator only, the loading shall not exceed 80 percent of the drum volume. When Ready-Mix Concrete is used, additional mortar (one sack cement, three parts sand and sufficient water) shall be added to the batch to coat the drum of the mixer or agitator truck, and this shall be required for every load of Class C concrete only and for the first batch from central mix plants. A portion of the mixing water, required by the batch design to produce the desired slump, may be withheld and added at the job site, but only with permission of the Engineer and under his supervision. When water is added under the above conditions, it shall be thoroughly mixed as specified below for water added at the job site. Mixing speed shall be attained as soon as all ingredients are in the mixer, and each complete batch (containing all the required ingredients) shall be mixed not less than 70 nor more than 100 revolutions of the drum at mixing speed except that when water is added at the job site, 25 revolutions (minimum) at mixing speed will be required to uniformly disperse the additional water throughout the mix. Mixing speed shall be as designated by the manufacturer. All revolutions after the prescribed mixing time shall be at agitating speed. The agitating speed shall be not less than one (1) nor more than five (5) rpm. The drum shall be kept in continuous motion from the time mixing is started until the discharge is completed. 12.

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 (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, forms shall be filleted at all sharp corners and edges with triangular chamfer 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 All fonns 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 fonns 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 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-Agitated Concrete: Above 80 degrees F 15 minutes Up to 80 degrees F 30 minutes Agitated 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 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 forms 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 fonns 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 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 forms. 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 (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 permission 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 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 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 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 anyone 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 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 1 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 maybe 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 SpLU. This curing method shall consist of overlapping sprays or sprinklers that keep all unformed surfaces continuously wet. (c) Pondin . 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 (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. TABLE 1 REQUIRED PERMITTED MEMBRANE MEMBRANE STRUCTURE UNIT WATER FOR WATER FOR DESCRIPTION FOR INTERIM FOR INTERIM CURING CURING CURING CURING 1 Top slabs of direct traffic culverts X X 2 Top surface of any concrete unit upon which concrete is to be placed and bonded at a later interval (Stub walls, risers, etc.). X Other superstructure concrete (wing walls, parapet walls, etc.) 3 Concrete pavement (base), curbs, gutters, retards, sidewalks, driveways, medians, X* X* islands, concrete structures, concrete riprap, etc. 4 All substructure concrete, culverts, box sewers, inlets, X* X* manholes, retaining walls *Polyethylene sheeting,burlap-polyethylene mats or laminated mats to prevent outside air from entering will be considered equivalent to water or membrane curing for items 3 and 4. 038000 Page 16 of 19 Rev.3-25-2015 Membrane curing shall not be applied to dry surfaces,but shall be applied just after free moisture has disappeared. 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 uniform 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 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 17. MEASUREMENT AND PAYMENT Unless otherwise specified on the Bid Form,no direct measurement or payment will be made for the work to be done or the equipment to be furnished under this specification,but it shall be considered subsidiary to the particular items required by the plans and the contract documents. 038000 Page 19 of 19 Rev.3-25-2015 SECTION 050200 WELDING 1. DESCRIPTION This specification shall govern for the field welding of structural steel and reinforcing steel. Provisions are made herein for the welding of the types of steel listed in Table 1, using the manual shielded metal-arc process, semi-automatic (manual) gas metal-arc welding and flux cored are welding processes. Other welding processes may be permitted with the specific approval of the Engineer and with qualification of the welding procedure. 2. STRUCTURAL STEEL GENERAL Final welds including tack welds to be incorporated therein shall be by a certified welder; certified welder being previously certified by tests as prescribed in the "Code for Welding in Building Construction," ASW D1.0-69, of the American Welding Society, to perform the type of work required. Miscellaneous welds may be made by a qualified welder; qualified welder being an experienced welder who is capable of making good welds of sound quality, but does not have certification papers; miscellaneous welds being welds that have no load carrying capacity in the completed structure. Tack welds shall be cleaned and fused thoroughly with the final weld. Defective, cracked or broken tack welds shall be removed. Welds shall be as required by the contract or erection drawings. The location or size shall not be changed without approval of the Engineer. The welder shall place his identification mark with crayon or paint near the groove welds made by him. No welding will be allowed when the air temperature is lower than 20'F, when surfaces are wet or exposed to rain, snow or wind, or when operators are exposed to inclement conditions that will hamper good workmanship. Any moisture present at the point of welding shall be driven off by heat before welding commences. Windbreaks shall be required for the protection of all welding operations. There shall be no temporary welds for transportation, erection or other purpose on main members, except at locations more than one-sixth the depth of the web from the flanges of beams and girders, as approved by the Engineer. On A514 steel, all groove welds in main members and in flanges of beams and girders subject to tensile stress or reversals of stress shall be finished smooth and flush on all surfaces, including edges, by grinding in the direction of applied stress, leaving the surfaces free from depressions. Chipping may be used provided it is followed by such grinding. Parts joined by groove welds connecting plates of unequal thickness or width shall have a smooth transition between offset surfaces at a slope not greater than one in four with the surface of either part. The surfaces shall be ground so that the radii at the points of transition will be four(4)inches minimum. 050200 Page 1 of 13 Rev.10-30-2014 All groove welds, except when produced with the aid of backing, shall have the root of the initial weld gouged, chipped or otherwise removed to sound metal before welding is started from the second side, except that back gouging will not be required when welding steel piling or armor joints with E6010 electrodes. The back side shall be thoroughly cleaned before placing back-up pass. When backing for welds is left in place to become a part of the structure, it shall be a single length insofar as possible. Where more than a single length is needed, they shall be joined by full penetration butt welds. The surfaces of this butt weld shall be ground flush as necessary to obtain proper fit-up in the weld joint. Before welding over previously deposited metal, all slag shall be removed, and the weld and adjacent base metal shall be cleaned. This requirement shall apply equally to successive layers, successive beads and the crater area. Arc strikes outside the area of permanent welds must be avoided on all steels. Where they do occur, resulting cracks and blemishes shall be ground out to a smooth contour and checked to insure soundness. Stringer bead technique shall be used where possible for groove welds on all types of steel. Weaving will not be permitted for A514 steel except in welding vertically upward, when a weave not exceeding two electrode diameters is permissible for manual shielded metal-arc welding. In all welding processes, the progression for all passes in vertical welding shall be upward using a back step sequence. Groove welds shall begin and terminate at the ends of a joint on extension bars. Edge preparation and thickness of extension bars shall be the same as that of the member being welded and shall extend a minimum of three-quarter(3/4) inch beyond the joint. Extension bars shall be removed with a cutting torch upon completion and cooling of the weld, and the flange edges shall be ground smooth. Any defects exposed by the grinding shall be cleaned, filled with weld metal, and reground to a uniform finish. All grinding shall be parallel to the flange. Excess grinding of the parent metal shall be avoided. 3. FILLER METAL Electrodes for manual shielded metal-arc welding shall conform to the requirements of the latest edition of "Specifications for Mild Steel Covered Arc-Welding Electrodes", AWS A5.1, or to the requirements of the latest edition of"Specifications for Low Alloy Steel Covered Arc-Welding Electrodes,"AWS A5.5. All electrodes and combination of electrode and shielding for gas metal-arc welding for producing weld metal with a minimum specified yield point not exceeding 60,000 psi shall conform to the requirements in the latest edition of, "Specification for Mild Steel Electrodes for Gas Metal-Arc Welding," AWS A5.18, or "Specification for Mild Steel Electrodes for Flux Cored Are Welding," AWS A5.20, applicable for the classifications producing weld metal having a minimum impact strength of 20 ft.-lb., Charpy V-notch, at a temperature of 0°F or below. For weld metal with a minimum specified yield strength exceeding 60,000 psi, the Contractor shall demonstrate that each electrode and flux or combination of electrode and shielding medium proposed for use will produce low alloy weld metal having the mechanical properties listed in Table A. 050200 Page 2 of 13 Rev.10-30-2014 The mechanical properties shall be determined from a multiple pass weld made in accordance with the test requirements of the latest edition of AWS A5.18 or AWS A5.20, as applicable.

Use of the same type electrode with the next higher mechanical properties, in accordance with AWS A5.1 or A5.5, than those listed will be permitted. 2. In joints involving base metals of different yield points or strengths, low hydrogen electrodes applicable to the lower strength base metal may be used. 050200 Page 4 of 13 Rev.10-30-2014 Before use, all electrodes with low hydrogen coverings conforming to AWS A5.1 shall be dried for not less than two hours between 450 and 500 degrees F and electrodes with low hydrogen coverings conforming to AWS A5.5 for not less than one hour at a temperature between 700 and 800 degrees F. Immediately after drying, electrodes shall be stored in ovens held at a temperature of at least 250 degrees F. E70 electrodes not used within four hours, E80 within two hours, and E110 within one-half hour after removal from the storage oven shall be redried before use. Electrodes with flux which has been wet, cracked or otherwise damaged, shall not be used. When used for welding A514 steel, electrodes shall be dried at least one hour at temperatures between 700 and 800 degrees F before being used. Electrodes may be redried only once. Suitable facilities for drying and storage of electrodes shall be furnished at the job site, along with thermometers for checking and controlling the oven temperature. In humid atmospheres, the times allowed for use without redrying may be reduced. When gas or gas mixture is used for gas metal-arc welding, it shall be of a welding grade having a dew point of-40'F or lower. The gas manufacturer shall furnish certification to the Engineer that the gas or gas mixture is suitable for the intended application and will meet the dew point requirements. Welding wire coils removed from the original package shall be protected or stored to keep their characteristics or welding properties intact. Rusty coils, or portions of coils, that are rusty shall not be used. Preheat Preheat ahead of welding both groove and fillet welds (including tack welding) will be required as shown in Table 2. Any moisture present at the point of welding shall be driven off by preheating before welding begins. When the base metal is below the required temperature, it shall be preheated so the parts being welded are not less than the specified temperature within three inches (3") of the point of welding. Preheat and interpass temperatures must be sufficient to prevent crack formation. The preheat temperatures shown in Table 2 are minimum and higher preheats may be necessary in highly restrained welds. Preheating equipment shall be adequate to maintain the entire joint at or above the specified temperature. When possible, a joint shall be completely welded before it is allowed to cool below the specified temperature,but shall always be welded sufficiently to prevent cracking before cooling is permitted. Usually preheat and interpass temperatures shall not exceed 400' F for thickness up to 11/2 inches and 450'F for greater thickness. These temperatures shall never be exceeded on A514 steel. The welder shall have and use approved equipment for checking preheat and interpass temperatures at all times while welding is in progress. For all groove welds, preheat temperature shall be measured on the side opposite to which the heat is applied at points about three inches (3") away from the joint. 050200 Page 5 of 13 Rev.10-30-2014
