AWARD OF CONTRACT Unless it elects to reject all bids, the OWNER will award the Contract as promptly as possible consistent with the time required for a thorough analysis of bids submitted.

Please see the Note at the top of the wage determination for more information. 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) (I) (ii)). 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. 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-011-0010 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 * 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. 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. Washington, DC 20210 4.) All decisions by the Administrative Review Board are final.

Fly-ash or Other Pozzolans used as admixtures shall conform to ASTM C-618. 200.04 - CONCRETE PROPORTIONING The Contractor shall be responsible for the design of concrete mixtures. Concrete shall be proportioned and produced to provide an average compressive strength as provided for herein. (f's_ specified compressive strength of concrete). A. Proportioning of concrete for the required fc shall be based on 28-day compressive test shall be based on laboratory trail batches performed by an independent testing laboratory meeting the requirements of ASTM E-329 and approved by the Engineer, and/or on the basis of field experience, both as set forth in ACI 318-Latest Edition and this specification. The average compressive strength used as a basis for selecting the proportions shall exceed the specified F'c as required by ACI 31B. B. Proportions of materials for concrete shall conform to minimum cement content and maximum water content for various classes as shown on Classification Table. C. Where different materials are to be used for different portions of the work, each combination shall be evaluated separately. D. Concrete proportions, including water-cement ratio, shall be established on the basis of field experience, or laboratory trial batches, with materials to be employed, as required herein. E. 1.5 lbs of fiber mesh per cubic yard of concrete, where noted for use on plans, shall be added to the mixer before placement. Fibermesh is required in all sidewalks. F. Average Strength Reduction After sufficient test data become available from the job, methods of "Recommended Practice for Evaluation of Compression Test Results of Concrete (ACI 214-65)" may be used to reduce the amount by which the average strength must exceed fc 1. Probable frequency of strength tests more than 500 psi below f'c will not exceed 1 in 100; 2. Probable frequency of an average of three consecutive strength tests below f'c will not exceed 1 in 100, and; 3. Concrete Classification Requirements Table are met. G. Evaluation and Acceptance of Concrete H. Frequency of Testing. Samples for strength tests of each class of concrete placed each day shall be taken not less than once a day, nor less than once for each 150 cubic yard of concrete, nor less than once for each 5000 sq. ft. of surface area for slabs or walls. ITEM 200 - STRUCTURAL CONCRETE On a given project, if total volume of concrete is such that frequency of testing required would provide less than five strength tests for a given class of concrete,tests shall be made from at least five randomly selected batches or from each batch if fewer than five batches are used. When total quantity of a given class of concrete is less than 50 cubic yards, strength tests may be waived by the Engineer if in his judgment adequate evidence of satisfactory strength is provided. Average strength of two cylinders from the same sample, tested at 28 days or the specified earlier age, is required for each strength test. Tests of Cured Specimens. Samples for strength tests shall be taken in accordance with "Method of Sampling Fresh Concrete" (ASTM C-172). Cylinders for strength tests shall be molded and laboratory-cured in accordance with "Method of Making and Curing Concrete Test Specimens in the Field" (ASTM C-31) and tested in accordance with "Method of Test for Compressive Strength of Cylindrical Concrete Specimens" (ASTM C-39). Strength level of an individual class of concrete shall be considered satisfactory if both of the following requirements are met: 1. The average of all sets of three consecutive strength tests equal or exceed required fo. 2. No individual strength test (average of two cylinders) falls below required to by more than 500 psi. J. Investigation of Low-Strength Test Results. If any strength test of cured cylinders falls below required to by more than 500 psi or if test indicate deficiencies in protection and curing, steps shall be taken to assure that load-carrying capacity of the structure is not jeopardized. If the likelihood of low-strength concrete is confirmed and computations indicate that load- carrying capacity may have been significantly reduced, tests of cores drilled from the area in question may be required in accordance with "Method of Obtaining and Testing Drilled Cores and Sawed Beams of Concrete" (ASTM C-42). In such case, three cores shall be taken for each strength test more than 500 psi below required f'o. If concrete in the structure will be dry under service conditions, cores shall be air dried (temperature 60•to 80• F, relative humidity less than sixty(60%) percent) for seven (7) days before test and shall be tested dry. If concrete in the structure will be more than superficially wet under service conditions, cores shall be immersed in water for at least 48 hours and be tested wet. Concrete in an area represented by core tests shall be considered structurally adequate if the average of three cores is equal to at least eighty-five (85%) percent of to and if no single core is less than seventy-five (75%) percent of f,. To check testing accuracy, locations represented by erratic core strengths may be retested. If criteria above are not met, and if structural adequacy remains in doubt, the Engineer may order load tests for the questionable portion of the structure, or take other action appropriate to the circumstances.

All laitance and other unsound material shall be removed before additional concrete is placed against hardened concrete. B. Mixing All concrete shall be mixed until there is a uniform distribution of materials and shall be discharged completely before mixer is recharged. Ready-mixed concrete shall be mixed and delivered in accordance with requirements set forth in "Specification for Ready-Mixed Concrete" (ASTM C-94). Job-mixed concrete shall be mixed in accordance with the following: 1. Mixing shall be done in a batch mixer of approved type. 2. Mixer shall be rotated at a speed recommended by the manufacturer. 3. Mixing shall be continued for at least 1-1/2 minutes after all materials are in the drum, unless a shorter time is shown to be satisfactory by the mixing uniformity tests of "Specification for Ready-Mixed Concrete" (ASTM C-94). C. Conveying Concrete shall be conveyed from mixer to place of final deposit by methods that will prevent separation or loss of materials. Conveying equipment shall be capable of providing a supply of concrete at site of placement without separation of ingredients and without interruptions sufficient to permit loss of plasticity between successive increments. D. Depositing Concrete shall be deposited as nearly as practicable in its final position to avoid segregation due to rehandling or flowing. Concreting shall be carried on at such a rate that concrete is at all times plastic and flows readily into spaces between reinforcement. Concrete that has partially hardened or been contaminated by foreign materials shall not be deposited in the structure. Retempered concrete or concrete that has been remixed after initial set shall not be used unless approved by the Engineer. ITEM 200 - STRUCTURAL CONCRETE After concreting is started, it shall be carried on as a continuous operation until placing of a panel or section, as defined by its boundaries or predetermined joints, is completed except as permitted or prohibited by Item 200.07.4.

B. High-early strength concrete shall be maintained above 50° F and in a moist condition for at least the first three (3) days, except when cured in accordance with 200.06.3. C. Accelerated Curing 1. Curing by high pressure steam, steam at atmospheric pressure, heat and moisture, or other accepted process, may be employed to accelerate strength gain and reduce time of curing, with prior approval of the Engineer. 2. Accelerated curing shall provide a compressive strength of the concrete at the load stage considered at least equal to required design strength at that load stage. 3. Curing process shall be such as to produce concrete with a curability at least equivalent to the curing method of 200.06.1 or 200.06.2. 4. Supplementary strength tests may be required to assure that curing is satisfactory. The Engineer may require strength tests of cylinders cured under field conditions to check adequacy of curing and protection of concrete in the structure. D. Cold Weather Requirements 1. Adequate equipment shall be provided for heating concrete materials and protecting concrete during freezing or near-freezing weather. 2. All concrete materials and all reinforcement, forms, fillers, and ground with which concrete is to come in contact shall be free from frost. 3. Frozen materials or materials containing ice shall not be used. E. Hot Weather Requirements During hot weather, proper attention shall be given to ingredients, production methods, handling, placing, protection, and curing to prevent excessive concrete temperatures or water evaporation that may impair required strength or serviceability of the member or structure. 200.07 - FORMWORK AND CONSTRUCTION JOINTS A. Design-Contractor shall be solely responsible for the form design for the anticipated work. 1. Forms shall result in a final structure that conforms to shapes, lines, and dimensions of the members as required by the design drawings and specifications. 2.

Forms for prestressed concrete members shall be designed and constructed to permit movement of the member without damage during application of prestressing force. B. Removal of Forms 1. No construction loads shall be supported on, nor any shoring removed from any part of the structure under construction except when that portion of the structure (in combination with remaining forming and shoring system) has sufficient strength to support safely its weight and loads placed thereon. Sufficient strength may be demonstrated by field-cured test cylinders and by a structural analysis considering proposed loads in relation to field-cured cylinder strengths and strength of the forming and shoring system. Such analysis and strength test data shall be furnished by the Contractor to the Engineer when so required. 2. No construction loads exceeding combination of superimposed dead load plus specified live load shall be supported on any unshored portion of the structure under construction, unless analysis indicates adequate strength to support such additional loads. 3. Forms shall be removed in such manner as not to impair safety and serviceability of the structure. All concrete to be exposed by form removal shall have sufficient strength not to be damaged thereby. 4.

Concrete protection of prestressing tendons shall conform to Section 7.7.3 - Prestressed Concrete of ACI 318 latest version. ITEM 201 - REINFORCEMENT STEEL 201.11 - PAYMENT No separate payment for work performed under this item. Include cost of same in contract price bid for work of which this is a component part. ITEM 400 - UNDERGROUND PIPING CONSTRUCTION 400.01 - DESCRIPTION This item shall govern the construction of water mains, sanitary sewers, and under drains, complete in place. This item provides for all clearing and grubbing, excavation, tunnelling, sheeting, bracing, embedment, connecting to new or old work, laying,jointing, excluding water, backfilling, tamping, and removal and replacement of street surfaces; and the furnishing of all materials, equipment, tools, labor, and incidentals for complete line construction. Point repairs to existing water or sewer lines are excluded from work under this item, except insofar as the items providing for point repairs may refer to this item. 400.02 - MATERIALS As specified elsewhere in the Technical Specifications. 400.03 - SEQUENCE OF WORK All gravity sewer lines shall be laid beginning at the downstream connection to existing facilities. When construction involves a main trunk having lateral or tributary lines, the latter shall not be started until the main trunk has been built to the point of their junction unless otherwise approved by the Engineer. All appurtenances shall be constructed as soon as the pipeline they serve is constructed to their location, rather than constructing them in advance or postponing construction. However, if construction reaches a point requiring installation of an appurtenance for which the materials are not immediately available, upon approval of the Engineer, the Contractor shall provide sufficient space for installation at a later time. The open ends of pipe shall be properly sealed and backfilled. The Contractor shall excavate the trench to finish grade fifty (50') feet to one hundred (100')feet ahead of the end of the completed pipeline. No excavation shall be performed farther than three hundred (300')feet beyond the completed pipeline, except for isolated excavations which may be required to locate existing utilities. These limitations shall not apply to tunnel installations. Each tunnel required by the plans and specifications shall be excavated, lined, and back packed for its entire length before laying pipe through the tunnel. For any tunnels constructed at the Contractor's option, the work sequence shall be as approved by the Engineer. 400.04 - PUBLIC CONVENIENCE AND SAFETY Materials stored about the work shall be so placed, and the work shall at all times be so conducted as to cause no greater obstruction to the traveling public than is considered necessary by the Engineer. Sidewalks must not be obstructed except by special permission of the Engineer. The materials excavated and the construction materials or plant used in the construction of the work shall be placed so as not to endanger the work, or prevent free access to all fire hydrants; water and gas valves; manholes for telephone, telegraph, signal, or electric conduits; sanitary or storm sewers; and fire alarm or police call boxes in the vicinity. The Contractor shall make provisions by bridges or otherwise at all cross streets, highways, sidewalks, and private driveways for the free passage of pedestrians and vehicles. Where bridging ITEM 400 - UNDERGROUND PIPING CONSTRUCTION is impractical or unnecessary in the opinion of the Engineer, the Contractor may make arrangements satisfactory to the Engineer for the diversion of traffic and shall, at his own expense, provide all material and perform all work necessary for the construction and maintenance of roadways and bridges for the diversion of traffic. At no time shall more than two (2) blocks be closed to traffic. Where practical, the Contractor shall leave at least two (2) access routes open to any residential or commercial area. If pipe line construction or construction traffic creates a need for dust control, as along dirt streets, the Contractor shall at his own expense perform all necessary sprinkling as directed by the Engineer. The Owner reserves the right to remedy any neglect on the part of the Contractor regarding public convenience and safety which may come to its attention, after twenty-four (24) hours notice in writing to the Contractor. In cases or emergency, the Owner shall have the right to remedy any neglect without notice. In either case, the cost of such work done by the Owner shall be deducted from monies due or to become due the Contractor. The Contractor shall notify the Engineer and the local street or road department forty-eight (48) hours in advance (excluding Saturdays, Sundays, and holidays) of the closing or obstruction of any street. Where the Contractor is required to construct temporary bridges or make other arrangements for crossings over ditches or streams, his responsibility for accidents shall include the roadway approaches as well as the structures of such crossings. 400.05 - BARRICADES, LIGHTS, AND WATCHMEN Where the work is being performed in or adjacent to any street, alley, or public place, the Contractor shall, at his own cost and expense, furnish and erect such barricades, fences, lights, and danger signals; shall provide such watchmen; and shall take such other precautionary measures for the protection of persons or property and of the work as are necessary. Barricades shall be recently painted in a color that will be visible at night. From sunset to sunrise the Contractor shall furnish and maintain adequate lights at each barricade. A sufficient number of barricades shall be erected to keep vehicles from being driven on or into any work under construction. The Contractor shall furnish watchmen in sufficient numbers to protect the work at all times from vandalism or related instances. The Contractor shall be held responsible for all damage to the work due to failure of barricades, signs, lights, and watchmen to protect it. Whenever evidence is found of such damage, the Engineer may order the damaged portion immediately removed and replaced by the Contractor at the Contractor's cost and expense. The Contractor's responsibility for the maintenance of barricades, signs, and lights, and for providing watchmen, shall not cease until the project has been accepted by the Owner. 400.06 - PROTECTION AND RESTORATION OF PROPERTY The Contractor shall not enter upon private property for any purpose without previously obtaining permission from the property owner. The Contractor shall notify the proper representative of any public utility, corporation, company, or individual not less than forty-eight(48) hours in advance of any work which might damage or interfere with the operation of their facilities along or adjacent to the work. ITEM 400 - UNDERGROUND PIPING CONSTRUCTION The Contractor shall be responsible for the preservation of all public and private property along or adjacent to the work, including trees, shrubbery, plants, lawns, fences, culverts, bridges, pavement, driveways, sidewalks, etc.; drainage facilities; and all underground or above ground utilities. Any pavement or sidewalks which must be removed shall be replaced according to Sections 400.16 and 400.17. The Contractor shall be responsible for all direct or indirect damage to property of any character resulting from any act, omission, or negligence in execution of the work; from non-execution of the work; or from defective work or materials. When any such damage occurs, the Contractor shall restore the affected property to a condition at least equal to its condition prior to the damage, or shall fully compensate the property owner. Such restoration shall be at the Contractor's expense, except for any items specifically designated in the plans and specifications. The Owner may, upon forty-eight (48) hours written notice (or without notice when a nuisance or hazardous condition occurs), proceed to restore any property damage which the Engineer deems necessary. The cost of such restoration will be deducted from any monies due or to become due the Contractor under this contract. If the Contractor discovers that existing utilities present obstructions to construction of lines or appurtenances, he shall immediately notify the Engineer. The Engineer will determine without delay whether existing improvements should be relocated, or whether the grade and/or alignment of the line should be changed. When necessary to move services, poles, guy wires, pipelines, or other obstructions, the Contractor will make necessary arrangements with the owner-operator of utilities. The Owner will not be liable for damages on account of delays due to changes made by owner-operator of privately owned utilities which hinder progress of work. The Owner will not be liable for cost incurred in relocatingutility service poles, services, and appurtenances (unless specifically designated for payment). 400.07 -CLEARING AND GRUBBING All trees, stumps, brush, roots, logs, rubbish, and other objectionable material in the path of the storm sewer, water line or sewer line shall be removed and disposed of in a manner satisfactory to the Engineer, without any extra compensation to the Contractor. 400.08 -TEMPORARY SEWER AND DRAIN CONNECTIONS When existing sewers or drains have to be taken up or removed, the Contractor shall take care of all sewage or drainage from these facilities. For this purpose, the Contractor shall provide and maintain, at his own expense, all necessary temporary connections, outlets, diversions, and pumping facilities. The Contractor shall dispose of all drainage and sewage from these facilities until the permanent connections are built and put into use, unless otherwise provided for in these specifications or as directed by the Engineer. All water or sewage shall be disposed of in a satisfactory manner so that no nuisance is created and so that the work under construction will be adequately protected. ITEM 400 - UNDERGROUND PIPING CONSTRUCTION 400.09 -TRENCH EXCAVATION 1. General. The Contractor shall excavate the trench to finish grade at least fifty (50') feet ahead of pipe laying unless physical conditions make this impractical. Bell holes shall be excavated in advance of pipe laying. If a trenching machine (not a backhoe) is used to excavate the trench for a water line, with Engineers approval, selected loose, fine excavated material may be used in lieu of sand embedment around the pipe. 2. Sewers. The ground shall be excavated by the open trench method to the required depth, line, and grade as indicated on the drawings. Excavated material shall not be removed from the site of work until backfilling is completed, except by permission of the Engineer. The sides of the trench shall be vertical to a point not less than twelve(12") inches above the top of the sewer pipe. The sides of the trench shall be between six (6") and eight (8") inches outside the pipe for pipe sizes ten (10") inches or less; and between eight (8") inches and twelve (12") inches outside the pipe for sizes larger than ten (10") inches. The bottom of the trench shall be excavated a minimum of four (4") inches below required grade and refilled to grade with thoroughly compacted select material bedding. 3. Water Mains. Trench requirements for water mains shall be the same as for sewer lines. 4. Other Trench Designs. If the specifications for the type of pipe being used contain special trench requirements, those requirements shall be followed in lieu of Subsection 2 or 3 above. 5. Unstable Soils. If unstable material is encountered at the bottom of the trench, the Contractor shall undercut and stabilize the trench with suitable materials such as shell or cement stabilized sand (one (1) sack cement per ton, or Class I embedment material in accordance with Item 500 and at the direction of the Engineer. 6. Locating Intersecting Pipes. Before laying a segment of line, the Contractor shall attempt to locate all utilities which might interfere with the proposed alignment and grade. He shall locate and excavate in advance all water lines, sewer lines, service lines, and appurtenances to which the proposed line will be connected, so that the Engineer can make any necessary adjustments in alignment or grade. The owners of all utilities crossing or closely paralleling the proposed alignment shall be notified in advance of construction. 7. Dewaterinq A. Under no circumstances shall surface water be allowed to flow in the trench. When ground water exists in the trench, the Contractor shall make attempts to drain it away from the pipe laying area or pump it out of the trench. Where necessary in the opinion of the Engineer, the Contractor shall dewater the trench by the well point method. The Contractor may also use well pointing at his option in other locations. If quicksand or water sand conditions appear in the trench bottom, the Contractor shall ITEM 400 - UNDERGROUND PIPING CONSTRUCTION undercut the trench and replace it with Class I embedment as follows: Angular, 1/4 to 1-1/2 inch graded stone including crushed stone, crushed shells, slag, cinders, etc. B. Trench Dewatering. Trench dewatering is sufficient removal of groundwater to keep an excavation reasonably dry. This means dry enough to eliminate the need for any special bedding and insure safe installation of the carrier pipe. The groundwater table shall be kept a minimum of two feet (2') below the bottom of the excavation. (1) Well Points. Where well points are used to dewater the trench the maximum allowable spacing shall be six feet (6') center to center. The minimum allowable depth of well points shall be equal to the depth of the excavation plus five feet (5'). Well points shall be set deeper if necessary to draw the groundwater down below the bottom of the excavation. Well points shall have metal well screens a minimum of two inches (2") in diameter and three feet (3') long. The well screens and riser shall be surrounded by filter sand up to the water table and the space above shall be sealed with clay. Two inch (2") diameter piezometers shall be installed at 250 foot centers to establish the extent that dewatering is necessary. At least one volume of water shall be ejected from the piezometer and then allowed to recharge prior to each groundwater measurement taken. (2) Deep Wells. Deep wells may be used as a means of trench dewatering provided the following information is submitted to the Engineer for his approval. (a) A certified well draw down curve prepared by a registered professional geotechnical engineer. Information to be submitted with the draw down curve shall include the type and classification of the soil to be dewatered, permeability of soil, and all information necessary for preparing curve. (b) Proposed well construction details including size of casing, type of pump, depth of well, filter material, screen details, and all other details necessary for well construction. (c) The rate of draw down of the groundwater table. Two inch (2") piezometers shall also be installed in the same manner as for well points to measure the groundwater table. The Engineer will use the draw down curve submitted above along with the groundwater table elevations to determine the maximum allowable spacing of the deep wells. (3) Other Methods. Other methods of trench dewatering may be used provided prior approval has been obtained from the Engineer. C. Dewatering of Tunnels. All tunnels and access pits shall be kept free of groundwater and surface water at all times. Method to be used shall be as approved by Engineer. Any cost incurred for dewatering of tunnels and access pits shall be included in the cost of installing the tunnel liner with no extra compensation. ITEM 400 - UNDERGROUND PIPING CONSTRUCTION D. Settlement. Prior to performing any dewatering, the Contractor shall take all necessary precautions to insure that the dewatering operation does not cause structures near the excavation to settle. 400.10 - SHEETING AND BRACING The Contractor shall provide all sheeting and bracing necessary for the protection of the work, employees, or any existing utilities or structures. No such sheeting shall be removed from below the spring line of the pipe after the pipe has been backfilled to this level. In the event the soil conditions are such that the Contractor should desire to leave such sheeting above the spring line in place, he shall secure the permission of the Engineer to do so. The cost of any necessary sheeting or bracing, whether left in place or removed, shall be included in the unit price of the pipe being laid. 400.11 - LAYING PIPE The Engineer will establish such general reference points and construction stakes as in his judgment will enable the Contractor to proceed with the work. The Contractor will be responsible for the layout of the work from these stakes and will protect and preserve the established reference points and construction stakes and will make no changes or relocations without prior written approval. He will report to the Engineer whenever any reference point or construction stake is lost or destroyed or requires relocation because of necessary changes in grades or locations. The Contractor will replace and accurately relocate all reference points and construction stakes so lost, destroyed, or moved. All pipe lines must be laid in a straight line, unless otherwise shown on the drawings, and with the flow line of the pipe accurately placed to the grade and alignment fixed by the Engineer. A joint shall be located within two (2) pipe diameters (thirty (30") inches maximum) outside the walls of each proposed manhole or junction box, both upstream and downstream. Joints shall also be placed near other rigid connections, or near the ends of pipe casings, when recommended by the manufacturer or by the appropriate ASTM specification. No variation from true and even grade, alignment, and invert will be permitted except to avoid existing underground main service lines of utilities, and then only upon the written permission of the Engineer, signed by him personally, should he find such deviation to be desirable and not detrimental to the pipe line. All pipes shall be laid with the spigot-end or tongue end downstream entering the bell or groove to full depth. Care shall be taken in placing pipe to prevent any earth being dragged into or left in the annular space for sealing of the joints. After the trench has been carefully graded and all bell holes excavated, the trench must receive the approval of the Inspector before any pipe is placed therein. Each piece of pipe shall be examined for defects and cut to the correct lengths. The interior surface and the bell and spigot shall be thoroughly cleaned of all foreign material prior to placing same in the trench in an approved manner. The pipe, valves, fittings, etc., shall be adjusted so as to be at their proper locations and then each spigot properly fitted into position. Each length of pipe shall rest on the bottom of the trench ITEM 400 - UNDERGROUND PIPING CONSTRUCTION throughout its entire length. Joints shall be as specified in the 500 series material technical specifications as provided herein. Instructions for jointing pipes with special couplings shall be in strict conformity with the Manufacturer's printed instructions. If a defective piece of pipe furnished and placed by the Contractor should collapse, the Contractor shall furnish at his expense all labor and materials required for removing and replacing the defective pipe and restoring the street or other surface to its condition prior to the failure of the pipe. All pressure piping shall have thrust blocks installed as designated on the drawings. 400.12 - PLUGGING ENDS Before leaving the work for the night, or at any time, any openings in the pipeline shall be securely closed with a tight fitting plug. Cost of plugging pipe ends shall be included with the cost of installing the pipe. 400.13 - PROTECTIVE COATINGS All metal, bolts, and nuts shall receive a protective coating with an asphaltic compound acceptableto the Engineer before backfilling. Surface preparation shall be in accordance with the coating manufacturer's recommendations. 400.14 -TIME OF BACKFILLING Backfilling shall begin as soon as the joints have been completed and all protective coating applied. All open trenches shall be completely backfilled before the work day ends, unless otherwise directed by the Engineer. 400.15 - BACKFILLING OF TRENCH 1. Lower Portion of Trench (initial backfill). Care shall be taken to see that no dirt clods or trench sides are allowed to fall and/or rest against the pipe prior to completion of the sand encasement. a. Sewer Lines. Six (6") inches of sand bedding shall be provided in the bottom of the trench (trench having been cut six (6") inches below grade), prior to laying the pipe and making up the joints. After the pipe has been placed, the backfill around and to a point twelve inches (12") above the top of the pipe shall be made in accordance with the installation specifications for the pipe material being installed as outlined in the 500 series material technical specifications provided herein. b. Water Lines. Six (6") inches of sand bedding shall be provided in the bottom of the trench (trench having been cut six (6") inches below grade), prior to laying the pipe and making up the joints. After the pipe has been placed, the backfill around and to a point six inches (6") above the top of the pipe shall be made in accordance with the installation specifications for the pipe material being installed as outlined in the 500 series material technical specifications provided herein. ITEM 400 - UNDERGROUND PIPING CONSTRUCTION 2. Upper Portion of Trench (final backfill). From the six(6")or twelve(12") inches above the top of the pipe upward, the type of backfill for various locations shall be as follows: a. Concrete or Asphalt Pavement. The trench shall be filled to two (2") inches below the bottom of the existing flexible base (or concrete pavement)with a mixture of clean sand and 1-1/2 sacks of cement per cubic yard. This material shall be placed in layers not more than six (6") inches thick and thoroughly tamped by mechanical or hand tamping, as directed by the Engineer. The Contractor may use, with prior approval from the Engineer, select native material in lieu of the sand-cement mixture. The select native material must be compacted to 90% density as measured by the Standard Proctor Density Test. Cost of testing shall be borne by the Owner. No further backfill is required for concrete pavement. Flexible base shall be replaced to the bottom of the pavement with a compacted base material, consisting of crushed limestone, iron ore gravel, or a sand-shell mixture. This requirement shall apply to all trenches running underneath surfaced streets, whether crossing the pavement or running along the street. b. Unsurfaced Streets. The trench shall be backfilled with selected loose, fine excavated material by means of water tamping or power tamping. The Engineer may require power tamping for heavily traveled streets. In using water tamping, the trench shall be filled to ten (10") inches below the surface with the loose fine material in even layers not exceeding eighteen (18") inches in thickness of loose material and immediately flooded to complete saturation and left undisturbed for three (3) days. The trench shall then be refilled and flooded again using poles to insure penetration of water to full depth of the trench. This flooding shall continue until there is no further settlement. Power tamping will be permitted only where the trench and backfill material are dry enough to permit satisfactory compaction. Backfill shall be placed in the trench in layers not exceeding twelve (12") inches in thickness. The top ten (10") inches of the trench shall be backfilled with shell or crushed limestone. On completion of the tamping, all of the excavated material shall be substantially replaced in the trench deducting the space occupied by the pipe, bedding, and shell or limestone. Compaction in all levels from six (6") inches or twelve (12") inches above the top of pipe to ten (10") inches below grade shall be not less than ninety (90%) percent of the maximum density value as determined by the "Standard Laboratory Method for Compaction and Density of Soil, AASHTO Designation T-99". The above procedure for unsurfaced streets shall apply in trenches runn ing in and parallel to and running across the normally maintained portion of the road or street right- of-way. c. Trench Within Right-of-Way, but Outside Pavement. Trenches within the right-of-way ofa surfaced street shall be backfilled according to the procedure for an unsurfaced street, except that the shell or crushed limestone in the top ten (10") inches of the trench shall be placed only in driveway crossings, roadway shoulders, and other areas where there ITEM 400 - UNDERGROUND PIPING CONSTRUCTION will be light traffic. Where the shell is omitted the ground shall be restored to its original condition by the replacement of grass or any other improvement which existed before the construction or which are shown on the plans to be constructed. d. Trenches Away from Streets.

ITEM 450 -TESTING SANITARY SEWER LINES 450.01 -GENERAL This specification shall provide for inspection and testing of all newly constructed sanitary sewer lines and manholes for watertight construction and for excessive deflection. 450.02 -WATERTIGHT CONSTRUCTION TESTING New sewer lines shall be tested by either a low pressure air test, an infiltration test, or an exfiltration test. The Contractor shall select one of these procedures for each new line, according to ground water conditions, subject to the approval of the Engineer. (Air testing is required for vitrified clay sewer lines). Leakage testing is not required for partial replacement of existing manhole segments. All new manholes shall be tested, as described in Item 450.08 below. 450.03 -GROUND WATER LEVEL Before conducting an air, exfiltration, or infiltration test on one or more adjacent line segments (the test section), the Contractor shall determine the ground water level at 400 foot intervals within thetest section. Each interval shall have a two (2") inch vertical pipe set in the ground it for this purpose. Some existing manholes may have this device or another device previously installed forthis purpose. Before testing the sewer lines, the Contractor shall insert a small rod into each two (2") inch pipe along the test section to determine the level of ground water in the pipe. If an existing manhole along the test section contains a nipple or other device for this purpose, the Contractor shall determine the ground water level by means of this device if practical. All ground water measurements shall be converted to depth of ground water above the pipe invert of the test section. The ground water depth for the test section shall be taken as the greatest depth so calculated. If no reliable measurement can be made,the ground water depth shall be taken as the greatest line depth along the test section. 450.04 -AIR TEST (PIPE OTHER THAN VCP) (Allowed for Lines Smaller Than 36" Only) When air testing is selected (for sewers other than vitrified clay), the Contractor shall conduct the test as follows. A. Conduct the test between two (2) consecutive manholes, as directed by the Engineer. B. Plug the test section at each end. One of the plugs used at the manhole shall be tapped and equipped for the air inlet connection for filling the line from an air compressor. C. Make sure that all plugs are properly braced against the internal pressure to prevent air leakage by slippage and blowouts. D. Connect air hose to tapped plug selected for the air inlet. Then connect the other end of the air hose to the portable air control equipment which consists of valves and pressure gauges used (a) to control the air entry rate to the test section, and (b) to monitor the air pressure in the pipe line. ITEM 450 -TESTING SANITARY SEWER LINES More specifically, the air control equipment shall include a shut-off valve, a pressure regulating valve, a pressure reduction valve, and a monitoring pressure gauge having a pressure range from zero (0)to fifteen (15) psi. The gauge shall have a minimum division of 0.10 psi and an accuracy of+ 0.04 psi. E. Connect another air hose between the air compressor and the air control equipment. F. Supply air to the test section slowly, filling the pipe line to a constant pressure of 3.5 psig plus 0.433 psi for each foot of ground water depth above the invert of the pipe. The air pressure must be regulated to prevent the pressure inside the pipe from exceeding 15.0 psig. G. When constant pressure of 3.5 psig plus ground water pressure adjustment (GWP) is reached, throttle the air supply to maintain the internal pressure above 3.0 psig plus GWP for at least five (5) minutes. If leakage is detected at any cap or plug, release the pressure in the line and tighten or repair the faulty plug. A new five (5) minute interval must be allowed afterthe pipe line has been refilled. H. After the stabilization period, adjust the air pressure to 3.75 psig plus GWP and shut off or disconnect the air supply. Commence timing when the air pressure reaches 3.5 psig +GWP with a stopwatch which is allowed to run until the line pressure drops to 2.5 psig plus GWP, at which time the stopwatch is stopped. The time required, as shown on the stopwatch, for a pressure loss from 3.5 psig to 2.5 psig is used to compute the air loss. I. If the time, in minutes and seconds, for the air pressure to drop 0.5 psig is greater than that calculated using the equation below, the test section shall have passed. J. If the time is less than calculated using the equation below, the test section shall not have passed and adequate repairs must be made. T= 0.0850(D)(K)/(Q) T = Time for pressure to drop 1.0 psig in seconds K = 0.000419 DL, but not less than one D = Average inside diameter of pipe (inches) L = Length of line of same pipe size in feet Q = Rate of loss, assume 0.0015 ft3/min/ft2of internal surface 450.05 -AIR TEST (VITRIFIED CLAY PIPE) Air testing of new sewer lines constructed of vitrified clay shall be conducted according to ASTM C- 828. 450.06 - INFILTRATION TEST PROCEDURES (SEWER LINES) When infiltration testing is selected, the Contractor shall conduct the test as follows: A. Conduct the test between two (2) or more adjacent manholes, as directed by the Engineer. ITEM 450 -TESTING SANITARY SEWER LINES B. The length of the test section shall be determined by field measurement by the Engineer. C. Plug all inlets and outlets at upstream manhole except the one for the line being tested. D. Cap or plug all service laterals, stubs, and fittings into the test section, so as to prevent ground water from coming in at these connections. E. When the test section consists of more than one manhole sections, plug all connecting sewer lines from intermediate manholes (unless the tributary lines are part of the test section). F. Place V-notch weir into the upstream pipe in the downstream manhole where the measurement will be recorded. The weir shall be installed so as to maintain a watertight seal between the weir and the interior surface of the pipe to prevent water bypassing the V-notch weir. G. V-notch weirs shall be constructed to a high degree of accuracy to avoid erroneous measurements. All weirs used for testing shall be approved by the Engineer. H. After V-notch weir has been installed, allow sufficient time for the infiltrating water to build up and level off behind the weir, until a steady, uniform flow passes over the V-notch weir. I. Measurements can be taken after steady flow occurs over the V-notch weir. Leakage shall be determined from the readings, either directly or by converting the readings of the flow into terms of gallons/(inch diam.--mile--day). Caution shall be taken in recording the readings due to possible variations in flow resulting from local conditions. All weir readings shall be made under the direction of the Engineer's representative. J. Repair and retest any test section exceeding the infiltration limits prescribed in Item 450.10 below. 450.07 - EXFILTRATION TEST PROCEDURES (SEWER LINES) When exfiltration testing is selected, the Contractor shall conduct the test as follows: A. Conduct the test between two (2) or more adjacent manholes, as directed by the Engineer. B. The length of the test section shall be determined by the Engineer. C. All service laterals, stubs, and fittings into the sewer line being tested shall be properly capped or plugged, and carefully braced to resist the thrust actions developed by the internal water pressure. D. Insert and tighten a tapped plug in each of the following locations: 1. Inlet pipe of downstream manhole, for connecting the water supply for filling the sewer. 2. Outlet pipe of upstream manhole, for connection to standpipe. li ITEM 450 -TESTING SANITARY SEWER LINES E. Place the standpipe in the upper manhole and connect it to the tapped plug. The standpipe shall be capable of handling from ten (10') feet to twenty-five (25') feet of water head to determine the tightness and soundness of the sewer line, as specified and directed by the Engineer. F. Introduce water into the line through the downstream manhole until the standpipe in the upstream manhole has been completely filled. G. Allow the line to stand for several hours after filling with water, before beginning the test. During this time some water absorption into the manhole structures and sewer pipe will take place. After the water absorption has stabilized, check the water level in the standpipe and add water if necessary. H. The test is now ready to begin. Measure and record the drop in the standpipe over a fifteen (15) minute period. To verify the first results, conduct a second fifteen (15) minute test. I. Convert the measured drops in the standpipe to leakage in terms of gallons/(inch diameter-- mile--day). J. Repair and retest any test section exceeding the infiltration limits prescribed in Item 450.10 below. 450.08 -TEST PROCEDURES (MANHOLES) The Contractor shall test each new manhole by an exfiltration test, as required by the following TCEQ Regulations. A. Hydrostatic Testing. Manholes shall be tested for leakage separately and independently of the wastewater lines by hydrostatic exfiltration testing, vacuum testing, or other methods acceptable to the commission. If a manhole fails a leakage test, the manhole must be made water tight and retested. The maximum leakage for hydrostatic testing shall be 0.025 gallons per foot diameter per foot of manhole depth per hour. Alternative test methods must ensure compliance with the above allowable leakage. Hydrostatic exfiltration testing shall be performed as follows: all wastewater lines coming into the manhole shall be sealed with an internal pipe plug, then the manhole shall be filled with water and maintained full for at least one hour. For concrete manholes a wetting period of 24 hours may be used prior to testing in order to allow saturation of the concrete. B. Vacuum Testing. To perform a vacuum test, on the owner shall plug all lift holes and exterior joints with a non-shrink grout and plug all pipes entering the manhole. No grout must be placed in horizontal joints before testing. Stub-outs, manhole boots, and pipe plugs must be secured to prevent movement while the vacuum is drawn. The owner shall use a minimum 60-inch /lb torque wrench to tighten the external clamps that secure the test cover to the top of the manhole. The test head must be placed at the inside of the top of the cone section, and the seal inflated in accordance with the manufacturer's recommendations. There must be a vacuum of 10 inches (4.912 psi) of mercury inside the manhole to perform a valid test. The test does not begin until after the vacuum pump is off. The manhole passes the test if after 2 minutes and with all valves closed, the vacuum is at least 9 inches (4.421 psi) of mercury. 450.09 -TEST RESULTS ITEM 450 -TESTING SANITARY SEWER LINES The Contractor shall furnish the test results in triplicate following the format of the form at the end of this section. Testing shall be performed as soon as practical after completing a section of sewer line. No more than 3000 feet of sewer may be laid without testing having been completed up to and including the last manhole in the line. 450.10 - INFILTRATION/EXFILTRATION LIMITS The maximum allowable infiltration/exfiltration rate shall be fifty (50) gallons/(inch diameter--mile-- day). 450.11 - DEFLECTION TESTING Deflection test shall be performed on all flexible and semi-rigid pipe. The test shall be conducted after the final backfill has been in place at least thirty (30) days. No pipe shall exceed a deflection of five percent (5%). If the deflection test is to be run using a rigid ball or mandrel, it shall have a diameter equal to ninety-five percent (95%) of the inside diameter of the pipe. The test shall be performed without mechanical pulling devices. 450.12 - PAYMENT No separate payment shall be made for testing of sewer lines and manholes.
