Union Rate Identifiers A four letter classification abbreviation identifier enclosed in dotted lines beginning with characters other than ""SU"' or ""UAVG"" denotes that the union classification and rate were prevailing for that classification in the survey. Example: PLUM0198-005 07/01/2014. PLUM is an abbreviation identifier of the union which prevailed in the survey for this classification, which in this example would be Plumbers. 0198 indicates the local union number or district council number where applicable, i.e., Plumbers Local 0198. The next number, 005 in the example, is an internal number used in processing the wage determination. 07/01/2014 is the effective date of the most current negotiated rate, which in this example is July 1, 2014. Union prevailing wage rates are updated to reflect all rate changes in the collective bargaining agreement(CBA) governing this classification and rate. Survey Rate Identifiers Classifications listed under the ""SU"' identifier indicate that no one rate prevailed for this classification in the survey and the published rate is derived by computing a weighted average rate based on all the rates reported in the survey for that classification. As this weighted average rate includes all rates reported in the survey, it may include both union and non-union rates. Example: SLTLA2012-007 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. tile:///C/Users/elsak/Desktop/Wage%20Determination/2021/tx21.txt[1/14/2021 4:48:52 PM] DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 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?

It is understood that rerouting of flow at the unit and the shutdown of portions of the unit for short and controlled durations, may be necessary to complete construction. However, Contractor shall work with the City and OAR to schedule work that may impact the bar screening and grit removal in such a manner that delivery of collected wastewater can still be provided from the Plant Lift Station to the downstream treatment units. The Contractor's project schedule will be structured to maintain capacity requirements. In the event that construction activity begins to impact upstream storage capacity and treatment constraints in a manner unforeseen by the Contractor, the Contractor shall immediately take all steps necessary to resolve the issue caused by construction and restore treatment capabilities. The Contractor shall provide the City and OAR a request for shutdown 30 calendar days prior to the scheduled temporary shutdowns or rerouting of flow. The City reserves the right to grant, delay, or deny such shutdowns or rerouting requests depending upon the anticipated weather conditions or other issues that would affect the ability to maintain delivery and treatment of the collected wastewater. In addition, the Contractor's overall construction schedule shall clearly highlight the anticipated scheduled shutdown and rerouting dates and duration. The time of any shutdowns will be decided by the City and will likely occur during night time. The Contractor shall not be entitled to additional payment for shutdown work scheduled during night-time,Sundays or holidays to meet the Williams Lift Station treatment demands.

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

DESCRIPTION This specification shall govern all work for excavation and backfill for utilities required to complete the project. 2. CONSTRUCTION (1) Unless otherwise specified on the drawings or permitted by the Engineer, all pipe and conduit shall be constructed in open cut trenches with vertical sides. Trenches shall be sheathed and braced as necessary throughout the construction period. Sheathing and bracing shall be the responsibility of the Contractor (refer to Section 022022 "Trench Safety for Excavations" of the City Standard Specifications). Trenches shall have a maximum width of one foot beyond the horizontal projection of the outside surfaces of the pipe and parallel thereto on each side unless otherwise specified. The Contractor shall not have more than 200 feet of open trench left behind the trenching operation and no more than 500 feet of ditch behind the ditching machine that is not compacted as required by the plans and specifications. No trench or excavation shall remain open after working hours. For all utility conduit and sewer pipe to be constructed in fill above natural ground, the embankment shall first be constructed to an elevation not less than one foot above the top of the pipe or conduit, after which excavation for the pipe or conduit shall be made. If quicksand, muck, or similar unstable material is encountered during the excavation, the following procedure shall be used unless other methods are called for on the drawings. If the unstable condition is a result of ground water,the Contractor,prior to additional excavation, shall control it. After stable conditions have been achieved,unstable soil shall be removed or stabilized to a depth of 2 feet below the bottom of pipe for pipes 2 feet or more in height; and to a depth equal to the height of pipe, 6 inches minimum,for pipes less then 2 feet in height. Such excavation shall be carried at least one foot beyond the horizontal limits of the structure on all sides. All unstable soil so removed shall be replaced with suitable stable material, placed in uniform layers of suitable depth as directed by the Engineer,and each layer shall be wetted, if necessary, and compacted by mechanical tamping as required to provide a stable condition. For unstable trench conditions requiring outside forms, seals, sheathing and bracing, any additional excavation and backfill required shall be done at the Contractor's expense. (2) Shaping of Trench Bottom. The trench bottom shall be undercut a minimum depth sufficient to accommodate the class of bedding indicated on the plans and specifications. 022020 Page 1 of 4 Rev.3-25-2015 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 (3) Dewatering Trench. Pipe or conduit shall not be constructed or laid in a trench in the presence of water. All water shall be removed from the trench sufficiently prior to the pipe or conduit planing operation to insure a relatively dry (no standing water), firm bed. The trench shall be maintained in such dewatered condition until the trench has been backfilled to a height at lease one foot above the top of pipe. Removal of water may be accomplished by bailing,pumping, or by installation of well-points, as conditions warrant. Removal of well- points shall be at rate of 1/3 per 24 hours (every third well-point). The Contractor shall prevent groundwater from trench or excavation dewatering operations from discharging directly into the storm water system. Groundwater from dewatering operations shall be sampled and tested, if applicable, and disposed of, in accordance with City Standard Specification Section 022021 "Control of Ground Water". (4) Excavation in Streets. Excavation in streets,together with the maintenance of traffic where specified, and the restoration of the pavement riding surface, shall be in accordance with drawing detail or as required by other applicable specifications. (5) Removing Abandoned Structures. When abandoned masonry structures or foundations are encountered in the excavation, such obstructions shall be removed for the full width of the trench and to a depth one foot below the bottom of the trench. When abandoned inlets or manholes are encountered and no plan provision is made for adjustment or connection to the new utility, such manholes and inlets shall be removed completely to a depth one foot below the bottom of the trench. In each instance,the bottom to the trench shall be restored to grade by backfilling and compacting by the methods provided hereinafter for backfill. Where the trench cuts through utility lines which are known to be abandoned, these lines shall be cut flush with the sides of the trench and blocked with a concrete plug in a manner satisfactory to the Engineer. (6) Protection of Utilities. The Contractor shall conduct his work such that a reasonable minimum of disturbance to existing utilities will result. Particular care shall be exercised to avoid the cutting or breakage of water and gas lines. Such lines,if broken, shall be restored promptly by the Contractor. When active wastewater lines are cut in the trenching operations, temporary flumes shall be provided across the trench while open, and the lines shall be restored when the backfilling has progressed to the original bedding line of the sewer so cut. The Contractor shall inform utility owners sufficiently in advance of the Contractor's operations to enable such utility owners to reroute, provide temporary detours, or to make other adjustments to utility lines in order that the Contractor may proceed with his work with a minimum of delay. The Contractor shall not hold the City liable for any expense due to delay or additional work because of utility adjustments or conflicts. (7) Excess Excavated Material. All materials from excavation not required for backfilling the trench shall be removed by the Contractor from the job site promptly following the completion of work involved. 022020 Page 2 of 4 Rev.3-25-2015 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 (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 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 Asphalt Roadways 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.

Application: The interior surface of each pipe shall be blast-cleaned to remove high temperature oxide film and to form an anchor pattern over the entire surface prior to heating and lining. Epoxy lining is to cover the inner surface of the pipe, extending from the plain or beveled end to the rear of the gasket socket. 3. Adhesion: Pipe shall be checked at the point of manufacture to assure bond of the lining to the pipe. Any indication of separation of lining from pipe is cause for rej ection. 4. Entrapped Material: Any sizeable protrusion in the lining, obviously caused by lining over foreign materials, shall be cause for rejection. 5. Separations: Linings which have separations caused during the lining operation shall be rejected. 6. Damages to Lining: Injurious mechanical damage, such as chuck marks and gouges, extending to bare metal are not acceptable. The pipe having such a defect shall be rejected. 7. Lining Thickness: Linings of nominal 40 mil thickness shall generally equal or exceed 40 mil throughout the pipe. At pipe ends, lining thickness may taper for a distance of 4 inches from the ends, to a minimum of 20 mil thickness. However, the lining shall not deviate by more than 5 mil from the 40 mil nominal thickness as required through the pipe. The lining thickness of each pipe and fitting shall be taken at the point of manufacture using a general electric magnetic dry film thickness device, digital coating thickness gauge, Positector 2000, or approved 026602 Page 2 of 7 Rev.10-30-2014 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 equal. Pipe and/or fittings with a lining thickness less than the minimum specified shall be rejected. 8. Bell and Plain End Overcoat: The bell socket and the last 2 inches of the plain end of each pipe shall be coated on the inside and outside with a factory applied mastic or epoxy coating. This coating shall be a minimum of 10 mil thickness and shall be Koppers 300M, Industrial Ruff Stuff, Roskote Mastic A-938, or equal. 9.

The manufacturer shall check each pipe and fitting for holidays at the point of manufacture with a high voltage holiday detection device. Tinker & Rasor Model AP-W, or approved equal. Testing shall be conducted at the voltage as calculated in Section 3: Testing and Voltages of the "Recommended Practice for High Voltage Electrical Inspection of Pipeline Coatings Prior to Installation" as published by the National Association of Corrosion Engineers (MACE) Technical Practices Committee. All actual holiday testing procedures shall conform to NACE standard RP-02-74 and American Society for Testing Materials (ASTM) Designation: G62- (latest) "Standard Test Methods for Holiday Detection in Pipeline Coatings." No holidays, misses or skips larger than a pinhole will be accepted for repair. A maximum of 6 holidays, as defined in ASTM Standard G62 and as determined by the detection test described above, on any one standard pipe length, fitting or special may be repaired with epoxy. 10. Independent Testing Laboratory Representation: All testing as specified herein including the lining thickness test and the holiday test shall be witnessed by a representative from an approved independent testing laboratory. The independent laboratory shall be a member of the American Council of Independent Laboratories. Manufacturer must submit for approval by the City the name of the testing laboratory and actual qualifications of actual representative that will witness the testing. The manufacturer shall furnish three (3) copies of report by independent testing laboratory depicting results of all testing witnessed by the independent laboratory. 11. Field Testing: Each pipe and fitting is subject to inspection in the field by the City for conformance to these specifications prior to installation. Any defects as specified herein with any pipe or fittings shall be grounds for rejection. 12. Sealing Cut Ends and Repairing Field Damaged Areas: Remove burrs from field cut ends and smooth out edge of epoxy lining. Remove all traces of oil or lubricant used during field cutting operation. All areas of loose lining associated with the cutting operation shall be removed and the exposed metal cleaned by sanding or scraping. For larger areas, roughen the bare pipe surface with a small chisel to provide an anchor pattern for the epoxy. The epoxy lining shall be "stripped" back by chiseling, cutting or scraping about V to 2" into well adhered 026602 Page 3 of 7 Rev.10-30-2014 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 lined area before patching. After removal of loose lining and dirt, the area to be patched shall be "scratched" or "gouged" to offer an anchor pattern for the epoxy. Include an overlap of 1" to 2" of roughened epoxy lining in the area to be epoxy coated. The roughening shall be done with a rough grade emery paper (40 grit), rasp, or small chisel. Avoid honing, buffing, or wire brushing since these tend to make surface to be repaired too smooth. With the area to be sealed or repaired absolutely clean and suitably "roughened," apply a thick coat of two-part coal tar epoxy. The detailed mixing and application procedure for the epoxy shall follow the epoxy manufacturer's instructions. This heavy coat of epoxy shall be "worked" into the scratched surface by brushing. The Contractor shall maintain a supply of epoxy on the job site as required to seal cut ends and repair damaged pipe when encountered. Epoxy shall be of the type recommended or supplied by the pipe manufacturer. 13. Warranty: A five year warranty shall be furnished by the manufacturer on the serviceability of the lining.

SCOPE: This specification governs all work required for disposal of waste from wastewater cleaning operations required to complete the project. 2. METHODS: Grit,rubble, dislodged bricks and other such inorganic waste that is removed during cleaning shall not be allowed to continue down stream of the operation. Organic solids that remain in suspension would be allowed to continue downstream through the wastewater system. A weir or other suitable trap shall be installed and maintained by the Contractor for the collection of such waste. This material shall be de-watered and delivered by the Contractor to a facility that is authorized to receive it. If this material is free of organic sludge and is sufficiently de-watered to pass the paint filter test,it would be acceptable for disposal at the Elliott Sanitary Landfill subj ect to prior approval of the facility and the associated disposal fees. The Contractor has the option of using the City's de-watering facilities. The City has six drying beds, each with a 1-foot high containment wall each with an area of about 2,300 square feet. These drying beds are at the Greenwood Wastewater Treatment Plant, 1541 Saratoga. The Contractor would be required to haul and handle the material to, at and from the facility as well as the restoration of drying beds. Restoration of the drying beds includes the removal of all the de- watered material and the replacement of the existing sand bed with new sand. All work required within the treatment plant, including the replacement of sand shall be in accordance with the requirements set forth by the Plant Supervisor. The use of the drying beds would be subject to prior approval of the facility and the associated de-watering fees. If the City's facilities are used for de-watering or disposal of waste, the Contractor shall be responsible for making contact with the appropriate Solid Waste or Wastewater Officials or both, making all arrangements for the use of City facilities, scheduling of delivery and pickup, etc. Materials and handling operations shall meet the requirements set forth by said Officials. Failure to meet these requirements shall be cause for rejection of the materials by either the landfill or the treatment plant operations. Proper disposal of this waste shall be responsibility of the Contractor. The Contractor shall provide the Engineer with written documentation of the proper disposal of this waste. 3. MEASUREMENT & PAYMENT: Unless otherwise specified on the Bid Form,this work shall be considered subsidiary to the project. 027604 Page 1 of 1 Rev.10-30-2014 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 SECTION 030020 PORTLAND CEMENT CONCRETE 1.

(7) Admixtures Calcium Chloride will not be permitted. Unless otherwise noted, air-entraining, retarding and water-reducing admixtures may be used in all concrete and shall conform to the following requirements: A "water-reducing, retarding admixture" is defined as a material which, when added to a concrete mixture in the correct quantity, will reduce the quantity of mixing water required to produce concrete of a given consistency and will retard the initial set of the concrete. A "water-reducing admixture" is defined as a material which, when added to a concrete mixture in the correct quantity, will reduce the quantity of mixing water required to produce concrete of a 030020 Page 4 of 13 Rev.10-30-2014 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 given consistency. (a) Retarding and Water-Reducing Admixtures. The admixture shall meet the requirements for Type A and Type D admixture as specified in ASTM Designation: C494, modified as follows: (1) The water-reducing retarder shall retard the initial set of the concrete a minimum of 2 hours and a maximum of 4 hours, at a specified dosage rate, at a temperature of 90°F. (2) The cement used in any series of tests shall be either the cement proposed for specific work or a "reference" Type I cement from one mill. (3) Unless otherwise noted on the plans, the minimum relative durability factor shall be 80. The air-entraining admixture used in the referenced and test concrete shall be neutralized Vinsol resin. (b) Air-Entraining Admixture. The admixture shall meet the requirements of ASTM Designation: C260, modified as follows: (1) The cement used in any series of tests shall be either the cement proposed for specific work or a "reference" Type I cement from one mill. (2) Unless otherwise noted on the plans, the minimum relative durability factor shall be 80. The air-entraining admixture used in the referenced concrete shall be neutralized Vinsol resin. 3. STORAGE OF CEMENT All cement shall be stored in well-ventilated weatherproof buildings or approved bins, which will protect it from dampness or absorption of moisture. Storage facilities shall be ample, and each shipment of packaged cement shall be kept separated to provide easy access for identification and inspection. The Engineer may permit small quantities of sacked cement to be stored in the open for a maximum of 48 hours on a raised platform and under waterproof covering. 4. STORAGE OF AGGREGATE The method of handling and storing concrete aggregate shall prevent contamination with foreign materials. If the aggregates are stored on the ground, the sites for the stockpiles shall be clear of all vegetation and level. The bottom layer of aggregate shall not be disturbed or used without recleaning. 030020 Page 5 of 13 Rev.10-30-2014 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 When conditions require the use of two or more sizes of aggregates, they shall be separated to prevent intermixing. Where space is limited, stockpiles shall be separated by physical barriers. Methods of handling aggregates during stockpiling and subsequent use shall be such that segregation will be minimized. Unless otherwise authorized by the Engineer, all aggregate shall be stockpiled at least 24 hours to reduce the free moisture content. 5. MEASUREMENT OF MATERIALS The measurement of the materials, except water, used in batches of concrete, shall be by weight. The fine aggregate, coarse aggregate and mineral filler shall be weighed separately. Where bulk cement is used, it shall be weighed separately, but batch weighing of sacked cement will not be required. Where sacked cement is used, the quantities of material per batch shall be based upon using full bags of cement. Batches involving the use of fractional bags will not be permitted. Allowance shall be made for the water content in the aggregates. Bags of cement varying more than 3 percent from the specified weight of 94 pounds may be rejected, and when the average weight per bag in any shipment, as determined by weighing 50 bags taken at random, is less than the net weight specified, the entire shipment may be rejected. If the shipment is accepted, the Engineer will adjust the concrete mix to a net weight per bag fixed by an average of all individual weights which are less than the average weight determined from the total number weighed. 6. CLASSIFICATION AND MIX DESIGN It shall be the responsibility of the Contractor to furnish the mix design, using a coarse aggregate factor acceptable to the Engineer, for the class(es) of concrete specified. The mix shall be designed by a qualified concrete technician to conform with the requirements contained herein and in accordance with the THD Bulletin C-11. The Contractor shall perform, at his own expense, the work required to substantiate the design, except the testing of strength specimens, which will be done by the Engineer. Complete concrete design data shall be submitted to the Engineer for approval. It shall also be the responsibility of the Contractor to determine and measure the batch quantity of each ingredient, including all water, so that the mix conforms to these specifications and any other requirements shown on the plans. Trial batches will be made and tested using all of the proposed ingredients prior to placing the concrete, and when the aggregate and/or brand of cement or admixture is changed. Trial batches shall be made in the mixer to be used on the job. When transit mix concrete is to be used, the trial designs will be made in a transit mixer representative of the mixers to be used. Batch size shall not be less than 50 percent of the rated mixing capacity of the truck. Mix designs from previous or concurrent jobs may be used without trial batches if it is shown that 030020 Page 6 of 13 Rev.10-30-2014 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 no substantial change in any of the proposed ingredients has been made. The coarse aggregate factor shall not be more than 0.82, except that when the voids in the coarse aggregate exceed 48 percent of the total dry loose volume, the coarse aggregate factor shall not exceed 0.85. The coarse aggregate factor shall not be less than 0.70 for Grades 1, 2 and 3 aggregates. If the strength required for the class of concrete being produced is not secured with the cement specified in Table 4, the Contractor may use an approved water-reducing or retarding admixture, or he shall furnish aggregates with different characteristics which will produce the required results. Additional cement may be required or permitted as a temporary measure until the redesign is checked. Water-reducing or retarding agents may be used with all classes of concrete at the option of the Contractor. When water-reducing or retarding agents are used at the option of the Contractor, reduced dosage of the admixture will be permitted. Entrained air will be required in accordance with Table 4. The concrete shall be designed to entrain 5 percent air when Grade 2 coarse aggregate is used and 6 percent when Grade 3 coarse aggregate is used. Concrete as placed in the structure shall contain the proper amount as required above with a tolerance of plus or minus 1.5 percentage points. Occasional variations beyond this tolerance will not be cause for rejection. When the quantity of entrained air is found to be above 7 percent with Grade 2 coarse aggregate or above 8 percent for Grade 3 coarse aggregate, additional test beams or cylinders will be made. If these beams or cylinders pass the minimum flexural or compressive requirements, the concrete will not be rejected because of the variation in air content. 7. CONSISTENCY In cases where the consistency requirements cannot be satisfied without exceeding the maximum allowable amount of water, the Contractor may use, or the Engineer may require, an approved water-reducing or retarding agent, or the Contractor shall furnish additional aggregates or aggregates with different characteristics, which will produce the required results. Additional cement may be required or permitted as a temporary measure until aggregates are changed and designs checked with the different aggregates or admixture. The consistency of the concrete as placed should allow the completion of all finishing operations without the addition of water to the surface. When field conditions are such that additional moisture is needed for the final concrete surface finishing operation, the required water shall be applied to the surface by fog spray only, and shall be held to a minimum. The concrete shall be workable, cohesive, possess satisfactory finishing qualities, and of the stiffest consistency that can be placed and vibrated into a homogenous mass. Excessive bleeding shall be avoided. Slump requirements will be as specified in Table 3. 030020 Page 7 of 13 Rev.10-30-2014 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 TABLE 3 Slump Requirements Concrete Designation Desired Slump Max.

QUALITY OF CONCRETE General The concrete shall be uniform and workable. The cement content, maximum allowable water- cement ratio, the desired and maximum slump and the strength requirements of the various classes of concrete shall conform to the requirements of Table 3 and Table 4 and as required herein. During the process of the work, the Engineer or his designated representative will cast test cylinders or beams as a check on the compressive or flexural strength of the concrete actually placed. Test cylinders must be picked up by the testing lab within 24 hours. A test shall be defined as the average of the breaking strength of two cylinders or two beams, as the case may be. Specimens will be tested in accordance with TxDOT Test Methods Tex-418-A or Tex-420-A. Test beams or cylinders will be required as specified in the contract documents. For small placements on structures such as manholes, inlets, culverts, wingwalls, etc., the Engineer may vary the number of tests to a minimum of one for each 25 cubic yards placed over a several day period. All test specimens, beams or cylinders, representing tests for removal of forms and/or falsework shall be cured using the same methods, and under the same conditions as the concrete represented. "Design Strength" beams and cylinders shall be cured in accordance with THD Bulletin C-11. The Contractor shall provide and maintain curing facilities as described in THD Bulletin C-11 for the purpose of curing test specimens. Provision shall be made to maintain the water in the curing tank at temperatures between 70°F and 90°F. When control of concrete quality is by twenty-eight-day compressive tests, job control will be by seven-day compressive tests which are shown to provide the required twenty-eight-day strength, based on results from trial batches. If the required seven-day strength is not secured with the 030020 Page 8 of 13 Rev.10-30-2014 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 cement specified in Table 4, changes in the batch design will be made.

MIXING CONDITIONS The concrete shall be mixed in quantities required for immediate use. 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 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 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.

(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 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 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.

The material shall have a minimum flash-point of 80 degrees F when tested by the "Pensky-Martin Closed Cup Method". It shall be of such consistency that it can be satisfactorily applied as a fine mist through an atomizing nozzle by means of approved pressure spraying equipment at atmospheric temperatures above 40 degrees F. It shall be of such nature that it will not produce permanent discoloration of concrete surfaces nor react deleteriously with the concrete or its components. Type 1 compound shall contain a fugitive dye that will be distinctly visible not less than 4 hours nor more than 7 days after application. The compound shall produce a firm, continuous,uniform moisture impermeable film free from pinholes and shall adhere satisfactorily to the surfaces of damp concrete. It shall, when applied to the damp concrete surface at the rate of coverage specified herein,be dry to the touch in not more than 4 hours, and shall adhere in a tenacious film without running off or appreciable sagging. It shall not disintegrate, check, peel or crack during the required curing period. The compound shall not peel or pick up under traffic and shall disappear from the surface of the concrete by gradual disintegration. The compound shall be delivered to the job only in the manufacturer's original containers, which shall be clearly labeled with the manufacturer's name, the trade name of the material, and a batch number or symbol with which test samples may be correlated. The water retention test shall be in accordance with TxDOT Test Method Tex-219-F. Percentage loss shall be defined as the water lost after the application of the curing material was applied. The permissible percentage moisture loss (at the rate of coverage specified herein) shall not exceed the 038000 Page 3 of 19 Rev.3-25-2015 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 following: 24 hours after application............2 percent 72 hours after application............4 percent Type 1 (Resin Base Only)curing compound will be permitted for slab concrete in bridge decks and top slabs of direct traffic culverts. (b) Mat curing of concrete is allowed where permitted by Table 1 in this specification or where otherwise approved by the Engineer. 3. EXPANSION JOINTS Joints and devices to provide for expansion and contraction shall be constructed where and as indicated herein or on the plans. All open j oints and j oints to be filled with expansion j oint material, shall be constructed using forms adaptable to loosening or early removal. To avoid expansion or contraction damage to the adjacent concrete, these forms shall be loosened as soon as possible after final concrete set to permit free movement without requiring full form removal. Prior to placing the sealing material, the vertical facing the joint shall be cleaned of all laitance by sandblasting or by mechanical routing. Cracked or spalled edges shall be repaired. The j oint shall be blown clean of all foreign material and sealed. Where preformed fiber j oint material is used,it shall be anchored to the concrete on one side of the joint by light wire or nails, to prevent the material from falling out. The top one inch(1") of the joint shall be filled with joint sealing material. Finished joints shall conform to the indicated outline with the concrete sections completely separated by the specified opening or joint material. Soon after form removal and again where necessary after surface finishing, all projecting concrete shall be removed along exposed edges to secure full effectiveness of the expansion joints. 4. CONSTRUCTION JOINTS The j oint formed by placing plastic concrete in direct contact with concrete that has attained its initial set shall be deemed a construction joint. The term "monolithic placement" shall be interpreted to mean at the manner and sequence of concrete placing shall not create construction joints. Construction joints shall be of the type and at the locations shown on the plans. Additional joints will not be permitted without written authorization from the Engineer, and when authorized, shall have details equivalent to those shown on the plans for joints in similar locations. Unless otherwise provided, construction joints shall be square and normal to the forms. Bulkheads shall be provided in the forms for all joints, except when horizontal. Construction joints requiring the use of joint sealing material shall be as detailed on the plans. The 038000 Page 4 of 19 Rev.3-25-2015 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 material will be specified on the plans without referenced to joint type. A concrete placement terminating at a horizontal construction joint shall have the top surface roughened thoroughly as soon as practicable after initial set is attained. The surfaces at bulkheads shall be roughened as soon as the forms are removed. The hardened concrete surface shall be thoroughly cleaned of all loose material, laitance, dirt or foreign material, and saturated with water so it is moist when placing fresh concrete against it. Forms shall be drawn tight against the placing of the fresh concrete. 5. FORMS (1) General. Except where otherwise specified, forms may be of either timber or metal. Forms for round columns exposed to view shall be of steel, except that other materials will be allowed with written permission of the Engineer. Forming plans shall be submitted to the Engineer for approval as specified. Forms shall be designed for the pressure exerted by a liquid weighing 150 pounds per cubic foot. The rate of placing the concrete shall betaken into consideration in determining the depth of the equivalent liquid. For j ob fabricated forms, an additional live load of 50 pounds per square foot shall be allowed on horizontal surfaces. The maximum unit stresses shall not exceed 125 percent of the allowable stresses used by the Texas Department of Transportation for the design of structures. Commercially produced structural units used in formwork shall not exceed the manufacturer's maximum allowable working load for moment, shear or end reaction. The maximum working load shall include a live load of 35 pounds per square foot of horizontal form surface, and sufficient details and data shall be submitted for use in checking formwork details for approval. Forms shall be practically mortar-tight,rigidly braced and strong enough to preventbulging between supports, and maintained to the proper line and grade during concrete placement. Forms shall be maintained in a manner that will prevent warping and shrinkage. Offset at form joints shall not exceed one-sixteenth of an inch(1/16"). Deflections due to cast-in-place slab concrete and railing shown in the dead load deflection diagram shall be taken into account in the setting of slab forms. All forms and footing areas shall be cleaned of any extraneous matter before placing concrete. Permission to place concrete will not be given until all such work is completed to the satisfaction of the Engineer. If, at any stage of the work, the forms show signs of bulging or sagging, the portion of the concrete causing such condition shall be removed immediately,if necessary, and the forms shall be reset and securely braced against further movement. 038000 Page 5 of 19 Rev.3-25-2015 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 (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 j oists 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 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 All forms shall be constructed to permit their removal without marring or damaging the concrete. The forms may be given a slight draft to permit ease of removal. Metal form ties of an approved type or a satisfactory substitute shall be used to hold forms in place and shall be of a type that permits ease of removal of the metal as hereinafter specified. All metal appliances used inside of forms for alignment purposes shall be removed to a depth of at least one-half inch (1/2") from the concrete surface. They shall be made so the metal may be removed without undue chipping or spalling, and when removed, shall leave a smooth opening in the concrete surface. Burning off of rods, bolts or ties will not be permitted. Any wire ties used shall be cut back at least one-half inch(1/2")from the face of the concrete. Devices holding metal ties in place shall be capable of developing the strength of the tie and adjustable to allow for proper alignment. Metal and wooden spreaders which are separate from the forms shall be removed entirely as the concrete is being placed. Adequate clean-out openings shall be proved for narrow walls and other locations where access to the bottom of the forms is not readily attainable. Prior to placing concrete, the facing of all forms shall be treated with oil or other bond breaking coating of such composition that it will not discolor or otherwise injuriously affect the concrete surface. Care shall be exercised to prevent coating of the reinforcing steel. (3) Metal Forms. The foregoing requirements for timber forms regarding design,mortar-tightness, filleted corners,beveled projections,bracing, alignment,removal,reuse and wetting shall also apply to metal forms, except that these will not require lining, unless specifically noted on the plans. The thickness of form metal shall be as required to maintain the true shape without warping or bulging. All bolt and rivet heads on the facing sides shall be countersunk. Clamps, pins or other connecting devices shall be designed to hold the forms rigidly together and to allow removal without injury to the concrete. Metal forms which do not present a smooth surface or line up properly shall not be used. Metal shall be kept free from rust, grease or other foreign materials. 6. PLACING REINFORCEMENT Reinforcement in concrete structures shall be placed carefully and accurately and rigidly supported as provided in the City Standard Specification Section 032020 "Reinforcing Steel". Reinforcing steel supports shall not be welded to I-beams or girders. 7. PLACING CONCRETE-GENERAL The minimum temperature of all concrete at the time of placement shall be not less than 50 degrees F. 038000 Page 7 of 19 Rev.3-25-2015 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 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 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 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 j oints in mass placements where differential settlement and/or setting time may induce stress cracking. Openings in forms shall be provided, if needed, for the removal of laitance of foreign matter of any kind. All forms shall be wetted thoroughly before the concrete is placed therein. All concrete shall be well consolidated and the mortar flushed to the form surfaces by continuous working with immersion type vibrators. Vibrators which operate by attachment to forms or reinforcement will not be permitted, except on steel forms. At least one stand-by vibrator shall be 038000 Page 9 of 19 Rev.3-25-2015 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 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 maybe placed when the atmospheric temperature is not less than 35 degrees F. Concrete shall not be placed in contact with any material coated with frost or having a temperature less than 32 degrees F. Aggregates shall be free from ice, frost and frozen lumps. When required, in order to produce the minimum specified concrete temperature,the aggregate and/or the water shall be heated uniformly, in accordance with the following: The water temperature shall not exceed 180 degrees F,and/or the aggregate temperature shall not exceed 150 degrees F. The heating apparatus shall heat the mass of aggregate uniformly. The temperature of the mixture of aggregates and water shall be between 50 degrees F and 85 degrees F before introduction of the cement. All concrete shall be effectively protected as follows: (a) The temperature of slab concrete of all unformed surfaces shall be maintained at 50 degrees F or above for a period of 72 hours from time of placement and above 40 degrees F for an additional 72 hours. 038000 Page 10 of 19 Rev.3-25-2015 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 (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 j ob site precast products,the requirements of the Article "Curing Concrete" of this specification shall apply. The Contractor is responsible for the protection of concrete placed under any and all weather conditions. Permission given by the Engineer for placing concrete during freezing weather will in no way relieve the Contractor of the responsibility for producing concrete equal in quality to that placed under normal conditions. Should concrete placed under such conditions prove unsatisfactory,it shall be removed and replaced at no additional cost. 038000 Page 11 of 19 Rev.3-25-2015 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 9. PLACING CONCRETE IN WATER Concrete shall be deposited in water only when specified on the plans or with written permission by the Engineer. The forms or cofferdams shall be sufficiently tight to prevent any water current passing through the space in which the concrete is being deposited. Pumping will not be permitted during the concrete placing, nor until it has set for at least 36 hours. The concrete shall be placed with a tremie, closed bottom-dump bucket, or other approved method, and shall not be permitted to fall freely through the water nor shall it be disturbed after it has been placed. The concrete surface shall be kept approximately level during placement. The tremie shall consist of a water-tight tube 14 inches or less in diameter. It shall be constructed so that the bottom can be sealed and opened after it is in place and fully charged with concrete. It shall be supported so that it can be easily moved horizontally to cover all the work area and vertically to control the concrete flow. Bottom-dump buckets used for underwater placing shall have a capacity of not less than one-half cubic yard. It shall be lowered gradually and carefully until it rests upon the concrete already placed and raised very slowly during the upward travel; the intent being to maintain still water at the point of discharge and to avoid agitating the mixture. The placing operations shall be continuous until the work is complete. 10. PLACING CONCRETE IN BOX CULVERTS In general, construction joints will be permitted only where shown on the plans. Where the top slab and walls are placed monolithically in culverts more than 4 feet in clear height, an interval of not less than one (1) nor more than two (2) hours shall elapse before placing the top slab to allow for shrinkage in the wall concrete. The base slab shall be finished accurately at the proper time to provide a smooth uniform surface. Top slabs which carry direct traffic shall be finished as specified for roadway slabs in Article"Finish of Roadway Slabs". Top slabs of fill type culverts shall be given a reasonably smooth float finish. 11. PLACING CONCRETE IN FOUNDATIONS AND SUBSTRUCTURE Concrete shall not be placed in footings until the depth and character of the foundation has been inspected by the Engineer and permission has been given to proceed. Placing of concrete footings upon seal concrete courses will be permitted after the caissons or cofferdams are free from water and the seal concrete course cleaned. Any necessary pumping or bailing during the concreting operation shall be done from a suitable sump located outside the forms. All temporary wales or braces inside cofferdams or caissons shall be constructed or adjusted as the work proceeds to prevent unauthorized construction joints in footings or shafts. 038000 Page 12 of 19 Rev.3-25-2015 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 When footings can be placed in a dry excavation without the use of cofferdams or caissons, forms may be omitted,if desired by the Contractor and approved by the Engineer,and the entire excavation filled with concrete to the elevation of the top of footing; in which case, measurement for payment will be based on the footing dimensions shown on the plans. 12. TREATMENT AND FINISHING OF HORIZONTAL SURFACES EXCEPT ROADWAY SLABS All unformed upper surfaces shall be struck off to grade and finished. The use of mortar topping for surfaces under this classification will not be permitted. After the concrete has been struck off, the surface shall be floated with a suitable float. Sidewalks shall be given a wood float or broom finish, or may be striped with a brush, as specified by the Engineer. Other surfaces shall be wood float finished and striped with a fine brush leaving a fine- grained texture. 13. FINISH OF ROADWAY SLABS As soon as the concrete has been placed and vibrated in a section of sufficient width to permit working,the surface shall be approximately leveled, struck off and screeded,carrying a slight excess of concrete ahead of the screed to insure filling of all low spots. The screed shall be designed rigid enough to hold true to shape and shall have sufficient adjustments to provide for the required camber. A vibrating screed may be used if heavy enough to prevent undue distortion. The screeds shall be provided with a metal edge. Longitudinal screeds shall be moved across the concrete with a saw-like motion while their ends rest on headers or templates set true to the roadway grade or on the adjacent finished slab. The surface of the concrete shall be screeded a sufficient number of times and at such intervals to produce a uniform surface, true to grade and free of voids. If necessary, the screeded surface shall be worked to smooth finish with a long handled wood or metal float of the proper size, or hand floated from bridges over the slab. When required by the Engineer,the Contractor shall perform sufficient checks with a long handled 10-foot straightedge on the plastic concrete to insure that the final surface will be within the tolerances specified below. The check shall be made with the straightedge parallel to the centerline. Each pass thereof shall lap half of the preceding pass. All high spots shall be removed and all depressions over one-sixteenth inch(1/16")in depth shall be filled with fresh concrete and floated. The checking and floating shall be continued until the surface is true to grade and free of depressions, high spots, voids or rough spots. Rail support holes shall be filled with concrete and finished to match the top of the slab. Surface Texturing. Perform surface texturing using a either carpet drag or metal tining as indicated on the drawings. Complete final texturing before the concrete has attained its initial set. Draw the carpet drag 038000 Page 13 of 19 Rev.3-25-2015 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 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 j ob until remedial action is taken. All concrete shall be cured for a period of four(4) curing days except as noted herein. 038000 Page 14 of 19 Rev.3-25-2015 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 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 subj ect 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 may be placed on the damp concrete surface for temporary protection prior to the application of the cotton mats which may be placed dry and wetted down after placement. The mats shall be weighted down adequately to provide continuous contact with all concrete surfaces where possible. The surfaces of the concrete shall be kept wet for the required curing time. Surfaces which cannot be cured by contact shall be enclosed with mats and anchored positively to the forms or to the ground so that outside air cannot enter the enclosure. Sufficient moisture shall be provided inside the enclosure to keep all surfaces of the concrete wet. (b) Water Spray. This curing method shall consist of overlapping sprays or sprinklers that keep all unformed surfaces continuously wet. (c) Ponding. This curing method requires the covering of the surfaces with a minimum of two inches (2") of clean granular material, kept wet at all times, or a minimum of one-inch 038000 Page 15 of 19 Rev.3-25-2015 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 (1") depth of water. Satisfactory provisions shall be made to provide a dam to retain the water or saturated granular material. (3) Membrane Curing. This consists of curing concrete pavement,concrete pavement(base),curbs, gutters, retards, sidewalks, driveways, medians, islands, concrete riprap, cement-stabilized riprap, concrete structures and other concrete as indicated on the plans by impervious membrane method. Unless otherwise provided herein or shown on the plans, either Type 1-D or Type 2 membrane curing compound may be used where permitted except that Type 1-D (Resin Base Only) will be required for slab concrete in bridge decks and top slabs of direct traffic culverts.

Formed surfaces and surfaces which have been given a first rub shall be dampened and shall be moist at the time of application of the membrane. When membrane is used for complete curing, the film shall remain unbroken for the minimum curing period specified. Membrane which is damaged shall be corrected immediately by reapplication of membrane. Unless otherwise noted herein or on the plans,the choice of membrane type shall be at the option of the Contractor. Only one type of curing compound will be permitted on any one structure. The membrane curing compound shall be applied after the surface finishing has been completed,and immediately after the free surface moisture has disappeared. The surface shall be sealed with a single uniform coating of curing compound applied at the rate of coverage recommended by the manufacturer and directed by the Engineer, but not less than 1 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 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 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 H cement is used, and not less than one-half day (12 hours) when Type III cement is used, provided it can be done without damage to the concrete. Forms for inside curb faces may be removed in approximately three hours provided it can be done without damage to the curb. 16. FINISHING EXPOSED SURFACES Concrete shall be finished as required in the specification Section for the respective item or as otherwise specified on the plans. An ordinary surface finish shall be applied to all concrete surfaces either as a final finish or preparatory to a higher finish. Ordinary Surface Finish shall be as follows: After form removal, all porous or honey-combed areas and spalled areas shall be corrected by chipping away all loose or broken material to sound concrete. Feather edges shall be eliminated by cutting a face perpendicular to the surface. Shallow cavities shall be repaired using adhesive grout or epoxy grout. If judged repairable by the Engineer, large defective areas shall be corrected using concrete or other material approved by the Engineer. Holes and spalls caused by removal of metal ties, etc., shall be cleaned and filled with adhesive grout or epoxy grout. Exposed parts of metal chairs on surfaces to be finished by rubbing, shall be chipped out to a depth of one-half inch(1/2") and the surface repaired. All fins, runs, drips or mortar shall be removed from surfaces which remain exposed. Form marks and chamfer edges shall be smoothed by grinding and/or dry rubbing. Grease, oil, dirt, curing compound, etc., shall be removed from surfaces requiring a higher grade of finish. Discolorations resulting from spillage or splashing of asphalt,paint or other similar material shall be removed. Repairs shall be dense, well bonded and properly cured, and when made on surfaces which remain exposed and do not require a higher finish, shall be finished to blend with the surrounding concrete. 038000 Page 18 of 19 Rev.3-25-2015 DocuSign Envelope ID:7C664F5C-F510-4833-AC01-2607445006F8 17.

Co-current systems shall not be allowed. The foul air shall enter the system at the bottom of each reactor and flow upward through each of the media layers. The media bed shall be intermittently irrigated from above using suitable reclaimed plant effluent or potable water in a once-through fashion. The water then trickles through the media and is collected in a sump at the bottom of the reactor. The drain water from the system will pass from the sump in the bottom of the reactor vessel and be piped to a discharge point as detailed on the Contract drawings. Systems using recirculation of irrigation water through the reactor vessel shall not be allowed. The hydrogen sulfide is oxidized by the autotrophic bacteria resident on the lower media layer(s). Because of the once-through irrigation configuration,a neutral-pH area of the media will be established,near the top of the media, providing conditions suitable for heterotrophic bacteria to oxidize other organic odorous compounds as required. The airstream is then released to the atmosphere via the exhaust stack at the top of the reactor. 1.04 REFERENCES The following is a list of standards which may be referenced in this section: A.

The information contained in these sheets meet or exceed the requirements shown in the "Texas Manual on Uniform o4) Traffic Control Devices" (TMUTCD). +o . 2The development and design of the Traffic Control Plan (TCP) is the responsibility ° D U) . g y L N 7 o. � of the Engineer. 3 L 00 zwo 3. The Contractor may propose changes to the TCP that are signed and sealed by a licensed professional engineer for approval. The Engineer may develop, sign and -� seal Contractor proposed changes. QD•- -t X00 4. The Contractor is responsible for installing and maintaining the traffic control Sv` devices as shown in the plans. The Contractor may not move or change the approximate 0. 0 location of any device without the approval of the Engineer. a,c°o LN$ 5. Geometric design of Ione shifts and detours should, when possible, meet the applicable 4).,o design criteria contained in manuals such as the American Association of State Highway . Dow and Transportation Officials (AASHTO), "A Policy on Geometric Design of Highways and Wog Streets, " the TxDOT "Roadway Design Manual " or engineering judgment. No N �F� 6. When projects abut, the Engineer (s) may omit the END ROAD WORK, TRAFFIC FINES DOUBLE, .0 and other advance warning signs if the signing would be redundant and the work areas +ao appear continuous to the motorists. If the adjacent project is completed first, the TNC Contractor sholl erect the necessary warning signs as shown on these sheets, the TCP DL•L sheets or as directed by the Engineer. The BEGIN ROAD WORK NEXT X MILES sign shall dao be revised to show appropriate work zone distance. L UI 0n° 7. The Engineer may require duplicate warning signs on the median side of divided �aE highways where median width will permit and traffic volumes justify the signing. TL C, 8. All signs shall be constructed in accordance with the details found in the ooL "Standard Highway Sign Designs for Texas, " latest edition. Sign details not shown woo in this manual shall be shown in the plans or the Engineer shall provide a detail wco to the Contractor before the sign is manufactured. L� + 'O woo 9. The temporary traffic control devices shown in the illustrations of the BC sheets ..aao are examples. As necessary, the Engineer will determine the most appropriate traffic W�E0 control devices to be used. d N N QL•"- U Da 10. As shown on BC(2), the OBEY WARNING SIGNS STATE LAW sign, STAY ALERT TALK OR TEXT o Yo LATER (see Sign Detail G20-10T) and the WORK ZONE TRAFFIC FINES DOUBLE sign with plaque shall be erected in advance of the CSJ limits. However, the TRAFFIC FINES DOUBLE sign will not be required on projects consisting solely of mobile operation work, such as striping or milling edgeline rumble strips. The BEGIN ROAD WORK NEXT X MILES, CONTRACTOR and END ROAD WORK signs shall be erected at or near the CSJ limits. 11. Except for devices required by Note 10, traffic control devices should be in place only while work is actually in progress or a definite need exists. 12. The Engineer has the final decision on the location of all traffic control devices. 13. Inactive equipment and work vehicles, including workers' private vehicles must be parked away from travel lanes. They should be as close to the right-of-way line as possible, or located behind a barrier or guardrail, or as approved by the Engineer. WORKER SAFETY APPAREL NOTES: SHEET 1 OF 29 Traffic Operations 1. Workers on foot who are exposed to traffic or Ir Texas Department of Transportation Standard to construction equipment within the right- of-way shall wear high-visibility safety apparel meeting the requirements of I SEA BARRICADE AND CONSTRUCTION "American National Standard for High-Visibility Apparel, " or equivalent revisions, and labeled GENERAL NOTES as ANSI 107-2004 standard performance for Class 2 or 3 risk exposure. Class 3 garments should AND REQUIREMENTS be considered for high traffic volume work areas or night t i me work.
