Air entraining, retarding and water reducing admixtures may be used in all concrete and shall conform to Item No. 405, "Concrete Admixtures ". 403.3 Storage of Cement Cement shall be stored in well ventilated. weatherproof buildings or approved bins which will protect it from dampness or absorp- tion 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 /Architect 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. 403.4 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 stock piles shall be clear of all vegetation. The bottom 61nch layer of aggregate shall not be disturbed or used without recleaning. When conditions require the use of 2 or more sizes of aggregates, they shall be separated to prevent intermixing. Where space is limited, stock piles shall be separated by physical barriers. Methods of handling aggregates during stockpiling and subsequent use shall be such that segregation will be minimized. All aggregate shall be stockpiled at least 24 hours to reduce the free moisture content. 403.5 Measurement of Materials The measurement of the materials, except water, used in batches of concrete shall be by weight or an accurate volumetric mea- suring method approved by the Engineer /Architect. 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. Allowances 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 shipments, 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. 403.6 Classification and Mix Design 11 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 commercial laboratory to conform with the requirements contained herein and conforming to SDHPT Bulletin C -11 and supplements thereto. The Contractor shall perform, at his own expense, the work required to substantiate the design, Including the testing of strength specimens. Complete concrete design data shall be submitted to the Engineer for approval. The mix design will be valid for a period of 1 year and shall be re- established for projects which extend beyond the 1 year period or when there is a change in materials. It shall also be the responsibility of the Contractor to determine and measure the batch quantity of each ingredient, including all water, not only for batch designs but for all concrete produced for the project so that the mix conforms to these specifications and any other requirements indicated. In lieu of the above mix design responsibility, the Contractor may request approval of a current design previously accepted by the City, if it can be shown that no substantial change in any of the ingredients has been made. However, this will not relieve the Contractor of the responsibility of providing concrete meeting the requirements of these specifications. The coarse aggregate factor shall not be more than 0.82 except that when the voids in the coarse aggregate exceed 48 bercent of the total dry loose volume, the coarse aggregate factor shall not exceed 0.85. The coarse aggregate factor shall not be less than 0.68.

Additional cement may be required or permitted as a temporary pleasure until he re- design is checked. Approved water reducing or retarding agents may be used with all classes of concrete at the option of the Contractor and will be required for hat weather concreting and for continuous slab placement The agents shall conform to item No. 405, "Concrete Admixtures" and Item No. 410, "Concrete Structures ". When a retarding admixture is required for hot weather concreting, the amount to be used shall conform to Item No. 405, "Con- crete Admixtures ". When used In continuous slab placement, the amount to be used will be established by several trial batches with varying retarder content and simulating the placing conditions to be encountered. 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 conforming to 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 ±11 percentage points. Variations beyond this tolerance may be cause for rejection. 403.7 Consistency 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 homogeneous mass within the slump requirements specified in Table 3.

A strength test shall be defined as the average of the breaking strength of 2 cylinders or 2 beams as the case may be. Specimens will be tested conforming to SDHPT Test Method Tex - 418 -A or Tex- 420-A. If the required strength or consistency of the class of concrete being produced cannot be secured with the minimum cement specified or without exceeding the maximum water /ce- ment ratio, the Contractor will be required to fumish different aggregates, use a water reducing agent, an air entraining agent or increase the cement content in order to provide concrete meeting these specifications. The Contractor may request beam or cylinder tests for removal of fors and/or falsework at his own expense. The lest speci- mens shall be cured using the same methods and under the same conditions as the concrete represented. "Design Strength" beams and cylinders shall be cured conforming to SDHPT Bulletin C -11 and Supplement thereto. When control of concrete quality is by 28 day compressive tests, job control will be by 7 day flexural or compressive tests which are shown to provide the required 28 day strength, based on resutts from trial batches. Thereafter, if the required 7 day strength is not secured with the quantity of cement specified in Table 4, changes in the batch design will be made as specified in Item No. 403, "Concrete for Structures ".

The tap should be made conforming to the pipe manufacturer's recommenciations with the Engineer's approval. Page 29 04/17/86 510 1 1 1 1 1 1 1 1 1' 1 1 1 1 1 1 1 1 1 1 Where not otherwise Indicated, service connections to mains shall be installed at an angle approximately 45 degrees above the horizontal. (b) Connections to the Existing System Unless otherwise specified by the Engineer, all connections made to existing mains shall be made at man- holes with the crown of the inlet pipe installed at the same elevation as the crown of the existing pipe. Service stubs Installed on the existing system shall be Installed by use of tapping saddles unless otherwise approved by the Engineer. Extreme care shall be exercised to prevent material from depositing in the existing pipe as the taps are being made. When connections to existing mains are made, a temporary plug approved by the Engineer must be installed downstream in the manhole to prevent water and debris from entering the existing system before final accep- tance. These plugs shall be removed after the castings are adjusted to finish grade or when final acceptance is given. (24) Water System Connections The Contractor shall, at his expense, make all necessary connections of new piping or accessories to the existing water system. To minimize any Inconvenience from outages, the Contractor shell schedule all such connections In advance and such schedule must be approved by the Superintendent of Water Division before beginning any work. (a) Shutoffs The City will make all shutoffs on existing water mains where more than one valve is involved. The Contractor will be required to notify the Engineer's field representative on the Job at least 24 hours prior to the desired time for any shutoff. Where only one valve will be operated, the Contractor may operate the valve under the imme- diate supervision of the Engineer's field representative. (b) Wet Connections to Existing Water System The Contractor shall make all wet connections called for by the Contract or required to complete the work. A wet connection shall include draining and cutting into existing piping and connecting a new pipeline or other extension into the existing pressure piping, forming an addition to the water transmission and distribution network. The contract price for wet connections shall be full payment for all necessary shutoffs, excavation, removing plugs and fittings, pumping water to drain the lines, cutting in new fittings, blocking and anchoring piping, bed- ding and backf fling, placing the lines and service and all site cleanup. No water containing detectable amounts of chlorine may be drained, released or discharged until specific plan- ning and appropriate preparations to handle, dilute and dispose of such chlorinated water are approved in advance by the City and the disposal operations shall be witnessed by an authorized representative from the City. Pressure Taps to Existing Water System The Contractor shall make all pressure taps called for by the Contract Documents or required to complete the work. A pressure tap shall consist of connecting new piping to the existing water system by drilling into the existing pipe while it is carrying water under normal pressure without taking the existing piping out of service. Unless otherwise provided by the Contract, the Contractor shall, at his expense, perform all necessary ex- cavation, furnish and install the tapping sleeve, valve and accessories, provide the tapping machine, drill the tap (unless otherwise indicated) and shall block, anchor and backfill the piping, valve and all accessories, place the new piping in service and perform all site cleanup. Where that the City will make the tap, City forces are not obligated or expected to perform any work except to provide tapping machine and drill the actual hole. The full cost of such drilling and any other work required of City crews in order to complete the drilling, will be charged to the Contractor and will be deducted from funds due the Contractor. (d) Service Connections Tapping of PVC or AC pipe for service connections may be made using either a service clamp or saddle or a tapping sleeve recommended by the manufacturer and approved as satisfactory by the Engineer. Direct tap- ping will not be permitted. (c) 510 04/17/86 Page 30 All service connections shall be installed so that the outlet is at an angle of approximately 45 degrees above horizontal at the main line. Precautions should be taken to ensure that the tapping saddle or sleeve Is placed on the pipe straight to pre- vent any binding or deformation of the PVC pipe. The mounting chain or U -bolt strap must be tight. Tapping shall be performed with a sharp shell type cutter so designed that It will smoothly penetrate heavy walled PVC 0R14 and 200 psi AC and will retain and extract the coupon from the pipe. (25) Backrlling (a) General After the pipe has been bedded, laid, jointed, approved and any bedding envelope placed, backfilling shall be done immediately in accordance with the details indicated, with approved material, except that when mortar joints are used for jointing storm sewers, no backfill above the bedding shall be placed until the mortar has cured for at least 6 hours. During backfilling operations, no heavy equipment which might damage the pipe will be allowed until a mini- mum cover of 12 inches above the top of pipe is obtained. During the backfilling operations, special emphasis is placed upon the need for obtaining uniform backfill ma- terial and uniform compacted density throughout the length and depth of the structure. Extreme care is to be taken to insure proper backfill over the pipe. The maximum lift of backfill shall be determined by the equipment selected and in no case shall it exceed 18 inches, loose measurement. All backfill In streets and under structures will be tested by the City and must satisfy the specified density requirements conforming to Section 00344, 'Testing Laboratory Services" before final acceptance. (b) General Corrugated Metal Pipe After the corrugated metal pipe structure has been completely assembled on the proper line and grade and headwalls constructed when Indicated, selected material free from rocks over 8 inches in size from excavation or borrow, as approved by the Engineer, shall be placed along both sides of the completed structures equally, in uniform layers not exceeding 6 inches in depth (loose measurement), sprinkled if required and thoroughly compacted between adjacent structures and between the structures and the sides of the trench or for a dis- tance each side of the structures equal to the diameter of the pipe if pipe is laid above the existing ground. Backfill material shall be compacted to the same density requirements as indicated for the adjoining sections of embankment in accordance with the governing specifications thereof. Above the 44 point of the structure, the fill shall be placed uniformly on each side of the pipe in layers not to exceed 12 inches, loose measure. Prior to adding each new layer of loose backfill material, until a minimum of 12 inches of cover is obtained over the crown of the pipe, an inspection will be made of the inside periphery of the corrugated metal structure to determine if any floating, local or unequal deformation has occurred as a result of improper construction methods. (c) Backfill Materials The Engineer may approve any of the following well graded materials: 1. Select trench material 2. Sand 3. Crushed rock cuttings 4. Rock cuttings 5. Foundation Rock 6. Blasted material with fines and rock 7. Cement stabilized material 8. Borrow Within the 100 year flood plan sand will not be permitted for bedding or backfilling. The Engineer shall approve the topsoil for areas to be seeded or sodded. (d) Backfill in Street Right of Way Placement of backfill under structures and within 2 feet of structures shall be compacted to the required den- sity using any method, type and size of equipment which will give the required compaction without damaging Page 31 04/17/86 510 1 1 1 1 1 1 1 1 1 ' 1 1 the pipe or bedding. The depth of layers, prior to compaction, shall depend upon the type of sprinkling and compacting equipment used and the test results thereby obtained. Prior to and In conjunction with the com- , paction operation, each layer shall be brought to the moisture content necessary to obtain the required density and shall be kept leveled to Insure uniform compaction over the entire layer. Testing for density will be in accor- dance with Test Method Tex -114 -E and Test Method Tex - 115 -E. Each layer of backfill must provide the density as required herein. Swelling soils (soils with plasticity Index 0120 or more) shall be sprinkled as required to provide not less than optimum moisture nor more than 2 per- cent over optimum moisture content and compacted to the extent necessary to provide not less than 95 per- cent nor more than 102 percent of the density as determined in accordance with Test, Method Tex - 114 -E. Nonswelling soils (soils with plasticity index less than 20) shall be sprinkled as required and compacted to the extent necessary to provide not less than 95 percent of the density as determined in accordance with Test Method Tex - 114 -E. After each layer of backfill Is complete, tests may be made by the Engineer. If the material fails to meet the density indicated, the course shall be reworked as necessary to obtain the Indicated compaction and the com- paction method shall be altered on subsequent work to obtain indicated density and conform tq Section 00344, "Testing Laboratory Services ". At any time, the Engineer may order proof rolling to test the uniformity of compaction of the backfill !ayer All irregularities, depressions, weak or soft spots which develop shall be corrected immediate by the Contactor. Should the backlit!, due to any reason or cause, lose the required stability, density or finish before the pave- ment structure is placed, it shall be recompacted and refinished at the sole expense of the Contractor. Exces- sive loss of moisture in the subgrade shall be prevented by sprinkling, sealing or covering with a subsequent backfill layer or granular material. Excessive loss of moisture shall be construed to exist when the subgrade soil moisture content is more than 4 percent below the optimum of compaction ratio density. Backfill shall be placed from the top of the bedding material to the existing grade, base course, subgrade or as indicated. The remainder of the street backfill shall be Flexible Base, Concrete or Hot Mix Asphalt Concrete as indicated or to replace in kind the surface removed to construct the pipe. Backfill in County Street or State Highway Right of Way All work within the right of way must meet the requirements of (d) above, as a minimum and shall meet the requirements of the permit issued by the County when their requirement are more stringent: Prior to the start of construction, the Contractor will be responsible for contacting the appropriate SDHPT office or County Commissioner's Precinct Office and for coordinating his activities with the operating procedures In effect for utility cut permits and pavement repair under their jurisdiction. Approval for all completed work in the State or County right of way must be obtained from the appropriate Official prior to final payment by the Owner. (f) Backfill in Railroad Right of Way All work within the railroad right of way must meet the requirements of (d) above, as a minimum and shall meet the requirements of the permit Issued by the Railroad Owner when their requirements are more stringent. Approval for all completed work in the railroad right of way must be obtained from the Railroad prior to final acceptance. (e) (g) Backfill in Easements Where not otherwise indicated, all backfill in easements across dedicated parkways, planting spaces, under or adjacent to utilities, structures, etc., shall satisfy all the requirements for backfill in streets Or under structures. Where there are no requirements for density, the Contractor may select whatever methods and procedures may be necessary to restore the entire work area to a safe, useful and geologically stable condition satisfac- tory to the Engineer and generally equal or superior to the conditions prior to construction. In and near the flood plain of all streams and watercourses and on all slopes subject to erosion by runoff, all backlili shall be compacted to at least 95 percent of maximum dry density as for street right of way, unless otherwise directed by the Engineer. All soil areas disturbed by the construction shall be covered with top soil and seeded conforming to Item No. 604, "Seeding for Erosion Control ". All turf, drainways and drainage structures shall be constructed or re- placed to their original condition or better. No debris shall remain in the drainways or drainage structures. (26) Quality Testing for Installed Pipe (a) 510' 04/17/86 Page 32 Wastewater Pipe Acceptance Testing After the construction is complete, the Engineer shall determine whether the pipeline is to be tested for infiltra- tion and extillration by the low pressure air test method. 1 1 1 1 1 ' 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Wastewater pipe installed In the City of Austin and its ETJ areas shall be tested for exfiltration and infiltration as described below In "Exfiltratlon Test" and "Infiltration Test" or by acceptable low pressure air test, as de- scribed below. At the conclusion of either test series, the work shall be further tested for pipeline settlement as described below. The Contractor shall be solely responsible for making proper structural repairs to those ele- ments which do not pass these test requirements. (b) Exfltration Test The pipeline shall be completely filled with water for its complete length or by sections as determined by the Engineer. If tested for its complete length, the maximum head at any point shall not exceed 25 feet unless otherwise Indicated. If tested in sections, the manholes in the test section shall be completely filled with water. After the pipeline has been filled and allowed to stand for 24 hours, the amount of exfiltration shall be calcu- lated. Any amount in excess of 200 gallons per inch of inside pipe diameter per mile per day shall be cause for rejection. • I (c) Infiltration Test When the pipe placed in easements Is completed, the upper portion of the ditch backfill shall be removed to a depth of not less than 18 Inches below the finished surface and width equal to the original trench width. The trench shall then be flooded with water until it is completely saturated and water stands In the ditch a minimum of 12 Inches deep. In cases of sleep terrain, earthen dikes shall be used to assure that water will stand over the trench. After it Is apparent that the trench is completely saturated, the main shall then be inspected with closed - circuit television for infiltration: Any section of the main or any service stub that indicates excessive infiltration shall be cause for rejection. This procedure shall not be used for pipes installed in areas where the P.I. of the surrounding material is 20 or higher or where the backfill material has a P.I. of 20 or more. (d) Pipeline Settlement Test During the infiltration test or after the exfiltration test, the pipe will be TV inspected for possible settlement. When air testing has been used, water shall be flowed into the pipe to permit meaningful observations. Any pipe settlement which causes excessive ponding of water. in the pipe shall be cause for rejection. (e) Low Pressure Air Test of Gravity Flow Wastewater Lines (1) General Wastewater lines in sizes for which the City has testing equipment may, at the discretion of the Engineer, be air tested between manholes. Backfilling to grade shall be completed before the test and all laterals and stubs shall be capped or plugged by the Contractor so as not to allow air losses which could cause an erroneous test result. Manholes are to be plugged so they are isolated from the pipe and cannot be included in the test. All plugs used to close the sewer for the air test must be capable of resisting the internal pressures and must be securely braced. Place all air testing equipment above ground and allow no one to enter a manhole or trench where a plugged sewer is under pressure. Release all pressure before the plugs are removed. The testing equipment used must include a pressure relief device designed to relieve pressure in the sewer under test at 10 psi or less and must allow continuous monitoring of the test pressures in order to avoid excessive pressure. Use care to avoid the flooding of the air inlet by infiltrated ground water. (Inject the air at the upper plug 0 possible.) Use only qualified personnel to conduct the test. (2) Ground Water Since the presence of ground water will affect the test results, test holes shall be dug to the pipe zone at intervals of not more than 100 feet and the average height of ground water above the pipe (if any) shall be determined before starting the test. (3) Test Procedure The Engineer may, at any time, require a calibration check of the instrumentation used. Use a pressure gauge having minimum divisions of 0.10 psi and an accuracy of 0.0625 psi. (One ounce per square inch.) All air used shall pass through a single control panel. Clean the sewer to be tested and remove all debris where indicated. Wet the sewer prior to testing. The average back pressure of any groundwater shall be determined (0.433 psi) for each foot of average water depth (if any) above the sewer. Add air slowly to the section of sewer being tested until the internal air pressure is raised to 4.0 psig greater than the average back pressure of any ground water that may submerge the pipe. Page 33 04/17/86 I 510 1 1 1 1 , 1 1 1 1 1 1 1 1 1� 1 1 1 I 11 1 1 After the Intemal test pressure Is reached, allow at least 2 minutes for the air temperature to stabilize, adding only the amount of alr required to maintain pressure. After the temperature stabilization period, disconnect the alr supply. Determine and record the time In seconds that Is required for the intemal alr pressure to drop tram 3.5 psig to 2.5 psig greater than the average back pressure of any ground water thpt may submerge the pipe. Compare the time recorded with the time required as follows: Pipe Size (Inches) 6 8 10 12 15 18 21 24 Time (Minutes) ' 3 4 5 6 7.5 9 10.5 12 Any drop In pressure, from 3.5 psig to 2.5 psig, In a time less than that required by the above table shall be cause for rejection. When the line tested includes more than one size pipe, the minimum time shall be that given for the largest size pipe included. When lines are air tested, manholes are to be tested separately by exfiltration or infiltration. (27) Pressure Pipe Hydrostatic Testing After the pipe has been Installed and backfilled and all service laterals, fire hydrants and other appurtenances in- stalled and connected. a leakage test, followed by a pressure test, will be conducted by the City. The City will furnish the pump and gauges for the tests. The Contractor will be present and shall furnish all necessary assistance for conducting the tests. The specified test pressures will be based on the elevation of the lowest point of the line or section under test. Before applying the specified test pressure, all air shall be expelled from the pipe. If permanent alr vents are not located at all high points, the Contractor shall install corporation cocks at such points. (a) Pressure Test The entire project or each valved section shall be tested, at a pressure of 200 psi for a sufficient period (ap- proximately 10 minutes) to discover all leaking or defective materials. Repairs shall be made by the Contractor to correct any leaking or defective materials. (b) Pressure Pipe Leakage Test A leakage test will follow the pressure test and be conducted on the entire project or each valved section. The leakage test shall be at 150 psi for at least 1 hour. ( Allowable Leakage 510 04/17/86 Page 34 Leakage shall be defined as the quantity of water that must be supplied into any test section of pipe to maintain the specified leakage test pressure (see above, "Pressure Pipe Leakage Test ") after the alr in the pipeline has been expelled and the pipe has been filled with water. The allowable leakage shall com- ply with AWWA C -600 which defines the allowable leakage as: L SD P 133,200 ' where L = Leakage In gallons per hour S = Length of pipe In feet D = Diameter (inside) of pipe In Inches P = Pressure in pounds per square Inch If such testing discloses leakage In excess of this specified allowable, the Contractor, at his expense, shall locate and correct all defects in the pipeline until the leakage Is within the indicated allowance. (28) Service Charges for Testing No charge will be made to the Contractor for the City's test equipment, inspection, etc., when the test results show that leakage is within the Indicated allowable limits. For each test, either for leakage or for pressure, which fails to meet the indicated requirements, the City's flat cl>arge of $50.00 for such tests will be charged to the Contractor and will be deducted from any funds due the Contractor. 1 1 1 1 1 1 1 i 1 1 1 1 1 1 1 1 1 1 1 1 1 (29) Sterilization of Potable Water Lines The Contractor shall protect all piping materials from contamination during storage, handling and installation. Prior to disinfection, the pipeline Interior shall be clean, dry and unobstructed. All dirt, debris, gasket lubricant, etc., shall be washed from the line by swabbing with hypochiorite solution and/or flushing with clean water. The City, at Its expense, will supply the test gauges and the concentrated disinfecting material and City personnel will supervise and direct the overall sterilization procedure. The Contractor, at his expense, shall provide all other equipment, supplies and the necessary labor to perform the sterilization under general supervision of the City. (a) Procedure and Dosage All valves shall be arranged to prevent the strong disinfecting dosage from flowing back into the existing water supply piping. The new pipeline shall then be completely filled with disinfecting solution by feeding thglconcen- trated chlorine and approved water from the existing system uniformly Into the new piping in such proportions that every part of the line has minimum concentration of 50 parts per million (50 pprh or 50 mg/liter) available chlorine. Unless otherwise indicated, all quantities called for herein refer to measurements by the testing procedures in the current edition of "Standard Methods ". The chlorine concentration of each step in the sterilization proce- dure shall be verified by chlorine residual determinations. This disinfecting solution shall be retained in the piping for at least 24 hours and all valves, hydrants, etc., shall be operated to disinfect all their parts. After this retention period, the water shall contain no less than 25 parts per million chlorine throughout the treated sec- tion of the pipeline. This heavily chlorinated water shall then be carefully flushed from the line until the chlorine concentration is no higher than the residual generally prevailing in the existing distribution system or approximately one part per million. Proper planning and appropriate preparations to handle, dilute and dispose of this strong chlorine solu- tion without causing Injury or damage to the public, the water system or the environment must be approved by the City before flushing of the line may begin and the flushing shall be witnessed by an authorized represen- tative of the City. (b) Bacteriological Testing After final flushing of the strong disinfecting solution, water samples from the line shall be tested for bac- teriological quality by the City and must be found free of coliform organisms before the pipeline may be placed In service. One test sample shall be drawn from the end of the main and additional samples collected at Inter- vals of not more than 1000 feet along the pipeline. The Contractor, at his expense, shall install sufficient sampling taps at proper locations along the pipeline. Each sampling tap shall consist of a standard corporation cock installed in the line and extended with a copper tubing gooseneck assembly. After samples have been collected, the gooseneck assembly may be removed and retained for future use. Samples for bacteriological analysis shall be collected only from suitable sampling taps in sterile bottles treated with sodium thiosulfate. Samples shall not be drawn from hoses, fire hydrants, etc. The City, at its expense, will furnish the sterile sample bottles and may, at its discretion, collect the test samples with City personnel. If the Initial disinfection fails to produce acceptable sample tests, the disinfection procedure shall be repeated (without extra compensation) until satisfactory test results have been obtained before the piping may be placed in service. (30) Cleanup and Restoration It shall be the Contractor's responsibility to keep the construction site neat, clean and orderly at all times. Cleanup shall be vigorous and continuous to minimize traffic hazards or obstructions along the streets and to drive- ways. Trenching, backfiil and cleanup shall be coordinated as directed by the City. The Engineer shall regulate the amount of open ditch and may halt additional trenching if cleanup is not adequate to allow for orderly traffic flow and access. Materials at the site shall be stored in a neat and orderly manner so as not to obstruct pedestrian or vehicular traffic. All damaged material shall be removed from the construction site immediately and disposed of in a proper manner. All surplus excavated materials become the property of the Contractor for disposal at his expense. After trenching, the Contractor shall immediately remove all excavated materials unsuitable for or in excess of, backfill requirements. Immediately following the pipe laying work as it progresses, the Contractor shall backlill, grade and compact all excavations as provided elsewhere and shall immediately clean up and remove all unused soil, waste and debris and restore all surfaces and improvements to a condition equal or superior to that before construction began and to Page 35 04/17/86 510 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 •an appearance which complements the surroundings. The Contractor shall grade and dress the top 6 Inches of earth surfaces with soil or other material similar and equal to the surrounding, till and smooth any visible tracks or ruts, replace and re- establish all damaged or disturbed turf or other vegetation and otherwise make every effort to en- courage the return of the entire surface and all Improvements to a pleasant appearance and useful condition appro- priate and complementary to the surroundings and equal or similar to that before construction began. 510.5 Measurement • Pipe will be measured by the linear foot along the centerline of the pipe for the various sizes and classes of pipe in place, in accordance with these specifications, complete and accepted by the Engineer, Including excavation and backfill, unless they are included in the bid as a pay item. Where wyes, branches or connections to existing pipe lines are involved, measurement of the new connecting pipe will be rirade from the Intersection of Its central axis with the outside surfaces of the pipe into which it connects. Where inlets, headwalls, catch basins, manholes, Junction boxes or other structures are Included In lines of pipe, that length of pipe tying into the structure wall will be included for measurement but no other portion of the structure length or width will be so included. , For multiple pipes, the measured length will be the sum of the lengths of the barrels measured as prescribed above. Any foundation mat required shall be measured by the cubic yard of the unstable material removed between the next line of the trench to a depth 2 feet below the design bedding elevation. 510.6 Payment Payment for pipe, measured as prescribed above, will be made at the unit price bid per linear foot for the various sizes of pipe, of the materials and class indicated, unless unstable material Is encountered or trench excavation and backlit] Is bid as a separate item. The foundation seal shall be paid for at the unit price bid per cubic yard, which shall be full payment or all excavation and removal of unsuitable material and furnishing, placing and compacting the foundation rock, coarse aggregate or other approved material all complete In place. Excavation and backfill, when included as a separate pay item, will be measured by Item No. 510 -C or D.
