The work shall be resumed when methods or defective work are corrected as ordered or approved in writing by the Engineer. In the event that a suspension of work is ordered as provided above» such suspension of work shall not relieve the contractor of his responsibility to complete the work within the time limit set forth in Section I* of the Special Provisions! and shall not be considered cause for extension of the time for completion, and further, such suspension of work shall not entitle the contrac- tor to any additional compensation. (i) Errors or Discrepancies Noted by Contractor; If the contractor, either before commencing work or in the course of the work, finds any dis- crepancy between the Specifications and the drawings, or between either and the physical conditions at the site of the work, or finds any error or omission in any of the drawings or in any survey, he shall promptly notify the Engineer in writing of such discrepancy, error or omission. If the contractor observes that any drawings or Specifications are at variance with any applicable law, ordinance, regulation, order or decree, he shall promptly notify the Engineer in writing of such conflict.

Carlsbad "A" & "3" Standard Provisions - 5 The contractor shall make such corrections as shall be required by the Engin- eer and receive the Engineer's stamp of approval before commencing the work in- volved. If the shop drawings show variations from the contract requirements because of standard shop practices or other reasons* the contractor shall make specific mention of such variations in his letter of transmittal in order that (if acceptable) suitable action may be taken for proper adjustment of the con- tract; otherwise, the contractor will not be relieved of the responsibility for executing the work in accordance with the contract, even though the shop draw- ings have been approved. Approval of shop drawings will be general and shall not relieve the contractor from the responsibility for proper fitting and con- struction of the work, nor from furnishing the material and work required by the contract which may not be indicated in the shop drawings when approved; neither does it relieve him from responsibility for errors in shop drawings.

Gene'ral Concrete cylinder pipe water main and fittings shall be installed at the locations and to the lines and grades shown on the plans and as herein specified. The pipe diameters shall be considered to be nominal diameters. B. Materials and Fabrication The materials and fabrication shall be in accordance with the requirements of Federal Specification for Pipe; Pressure* Reinforced Concrete> Pretensioned Reinforcement (Steel Cylinder Type) SS-P-381, September 14, 1955. The pipe to be installed at the various locations is identified on the plans by symbol indicating bidding schedule* nominal diameter of pipe* and pressure class. For example* pipe identified as lC-24"-150 would be the designation for bidding schedule 1C* 24" nominal diameter pipe* 150 p.s.i. working pressure. C. Installation C-l. Excavation and Backfill; Excavation and backfill shall conform to the Standard Specifications for Earthwork. C-2. Installation Procedures and Workmanship; Prior to laying the pipe* the bottom of the trench shall be graded and prepared to provide a firm and uniform bearing throughout the entire length of each joint of pipe. Bell holes of ample dimension shall be dug in the bottom of the trench at the location of each joint to facilitate the joining. The trench shall have a flat or semi-circular bottom conforming to the grade to which the pipe is to be laid. Pipe shall not be laid on earth mounds. When the pipe is being laid* the ends of the pipe shall be thoroughly cleaned and the gasket placed in the groove on the spigot ring and the spigot end of the pipe shall then be entered into the bell of the adjoining pipe and forced into position. The gasket and the inside surface of the bell shall be lubricated with a suitable vegetable soap compound which will facilitate the telescoping of the joints. Just prior to joining the two ends together* each end of the pipe shall be "buttered" with cement mortar in such a manner and in sufficient quantity to completely fill the space between the respective mortar linings. After the joining is com- pleted the pipe interior shall be swabbed to remove all excess mortar by drawing an approved type swab or squeegie through the pipe. For pipe twenty-four inches (24") in nominal diameter and larger, the inside of the joints shall be pointed by hand. The outside joint recess shall be poured with grout after a felt sheet or other suitable material has first been placed around the pipes at the joints and held securely in place to prevent leakage while the joint is being poured. The grout shall consist of one part cement to one and one-half Carlsbad "A" Concrete Cylinder Pipe Std. -1 parts sand and be mixed to the consistency of thick cream. The joints shall be poured and rodded from one side only until the grout shows on the other side. Care shall be used to fill the joint completely. Approxi- mately two hours subsequent to the pouring of the joint, the joint shall be rechecked and if any settlement, leakage, or shrinkage has taken place, the joint shall be refilled with grout. C-3. Field Melded Joints; Where welded joints are designated on the plans, the pipe shall first be joined with rubber gaskets as above described. The outside recess between the bell and spigot may then be filled with wire to facilitate the welding. The weld shall be continuous for the full circum- ference of the joint. C-4. Concrete Thrust Blocks; Concrete thrust blocks shall be placed as shown on the plans and shall consist of Class B, Portland Cement Concrete containing not less than five (5) sacks of Portland Cement per cubic yard and shall conform to the applicable provisions of Sections 26 and 27 of the State of California, Department of Public Works, Division of Highways Standard Specifications dated August 1954, except that the cement used shall conform to ASTM Specifications C 150-49, Type II. Concrete blocks shall be placed between the undisturbed ground and the fitting to be an- chored. Quantity of concrete and the area of bearing on the pipe and un- disturbed soil shall be as shown on the plans or directed by the Engineer. The concrete shall be so placed, unless specifically shown otherwise on the plans, that the pipe joints and fittings will be accessible to repairs. C-5. Preventing Foreign Matter From Entering the Pipes; At times when the pipe laying is not in progress, the open ends of the pipe shall be closed by a wooden plug or by other means approved by the Engineer. This provision shall apply during the noon hour as well as over night. C-6. Testing; After the pipe has been laid, the pipeline or any valved section of it shall be subjected to a hydrostatic pressure test of seventy- five pounds per square inch (75 psi) in excess of the designated working pressure for the Class of pipe being tested. The duration of the pressure test shall be four hours and the test shall be conducted in the following manner: All air shall be expelled from the pipe. To accomplish this, if air valves or hydrants or other outlets are not available, taps shall be made at the high points in the pipeline to expell the air and these taps shall be tightly plugged afterwards. The pressure in the pipeline shall then be pumped up to the specified test pressure. When the test pressure has been reached, the pumping shall be discontinued until the pressure in the line has dropped 50 psi, at which time the pressure shall again be pumped up to the specified test pressure. This procedure shall be repeated until four hours have elapsed from the time the specified test pressure was first applied. At the end of the four hour period, the pressure shall be pumped up to the test pressure for the last time. The leakage shall be considered as the total amount of water pumped into the pipeline during the four hour period including the amount required in Carlsbad "A" Concrete Cylinder Pipe Std. - 2 reaching the test pressure for the final time. Leakage shall not exceed the rate of twenty (20) gallons per inch of diameter per mile of pipe per twenty-four (24) hours. Any noticeable leak shall be stopped and all defective pipe, fittings* valves and other accessories discovered in consequence of the test, shall be removed and replaced by the contractor with sound material and the test shall be repeated until the total leakage during a test of four (4) hours duration, does not exceed the rate specified above. All concrete anchor blocks shall be allowed to cure for at least five (5) days prior to testing and all mortared joints shall be allowed to cure for not less than three (3) days prior to testing. C-7. Sterilization; Subsequent to the pressure tests and prior to ac- ceptance of the work, the entire pipeline including all valves, fittings and other accessories shall be sterilized in accordance with American Water Works Association "Standard Procedure for Disinfecting Water Mains AWWA C 601-54". Treated water shall be retained in the pipes for at least twenty-four (24) hours and a residule at not less than five (5) ppm shall be produced in all parts of the line after the twenty-four (24) hour period has elapsed. During the sterilization process all valves and other accessories shall be operated. After chlorination, the water shall be flushed from the line at its extremities until the replacement water tests are equal chemically and bacteriologically to those of the permanent source of supply. The water required for sterilization and flushing shall be furnished by and at the expense of the Contractor. D. Measurement and Payment D-l. Measurement; Measurement for payment for concrete cylinder pipe and fittings will be made along the centerline of the pipe from pipe end to valve flange or to centerline of intersecting pipe as the case may be, as actually constructed complete in place and in accordance with the plans and these specifications.

Specification C-39, or the latest revision thereof. B-5.3. Application and Treatment; The mortar shall be applied to the interior surface of the pipe by means of equipment specifically designed for the purpose, using a trough or troughs or a retracting feed line or lines in such a manner that uniform distribution through- out the length of pipe is attained. The pipe shall be slowly rotated with its axis in a horizontal position while the mortar is being introduced to assist in uniformity of distribution. Both ends shall be provided with suitable end dams during the spinning operation. These dams shall assist in controlling the thickness of the mortar coating being applied and shall provide a square-finished end for the lining. After application of the mortar, the rate of rotation of the pipe shall be uniformly increased to a speed that will compact the mortar. This speed shall be maintained until all excess water has been forced to the surface. During the spinning operation surplus water shall be Carlsbad "A" Steel Pipe Stds. - 4 expelled from the pipe by means of a blower or other suitable means. The peripheral speed and the length of spinning time shall be suffi- cient to obtain a dense* well-compacted lining with a smooth surface free from all defects. The thickness of the lining shall be in ac- cordance with the table given in the Detail Specifications. Immediately after completion of the above operation, the lining shall be water cured without being disturbed for at least 7 days in a manner that will prevent loss of moisture. This curing time may be reduced to a minimum of four (4) days if an exterior cement mortar coating is to be applied to the pipe. B-6.

Application and Treatment: After the interior of the pipe has been lined, a cement mortar coating shall be applied to the outside of each section of pipe by means of a nozzle or noz- zles, through which the mortar is forcibly expelled against the outside surface of the pipe in such a manner as to form an even, dense and tightly adhering coating. During the coating operation, the pipe shall be rotated and moved in a longitudinal direction beneath the nozzles. The rotation andloagitudinal travel of the pipe shall be uniform and at the proper rate to provide a coating having a minimum thickness of 3/4 inch. The standard reinforcing for the cement mortar coating shall be spirally wound steel rein- forcing wire embedded in the center of the coating. The wire shall be a bright basic wire of low carbon, open hearth steel,not annealed after the last draw, with an approximate ultimate tensile strength of 80,000 p.s.i. and shall be No. 15^- gauge at a pitch of one (1) inch. Immediately after the coating has been completed, the outside of each end of each section shall be cleansed to bare metal, and shall have the mortar trowelled and shaped to suit the type of joint being used. All bare metal exposed at the ends of each section of pipe shall be cleaned and protected against cor- rosion. Each day's production of cement mortar lined and coated pipe shall be plainly identified by indelible markings inside of one (1) of each joint.

Just prior to joining the two ends together, each end of the pipe shall be "buttered" with cement mortar in such a manner and in sufficient quantity to completely fill the space between the respective mortar linings. After the joining is completed, the pipe interior shall be swabbed to remove all excess mortar by drawing an approved type swab or squeegie through the pipe. For pipe twenty-four inches (24") in nominal diameter and larger, the inside of the joints shall be pointed by hand. One of the following coatings shall be applied to the joint exterior as appropriate. (a) The outside joint recess shall be poured with grout after a felt sheet or other suitable material has first been placed around the pipes at the joints and held securely in place to prevent leakage while the joint is being poured. The grout shall consist of one part cement to one and one-half parts sand and be mixed to the consistency of thick cream. The joints shall be poured and rodded from one side only until the grout shows on the other side. Care shall be used to fill the joint completely. Approximately two hours subsequent to the pouring of the joint* the joint shall be rechecked and if any settlement, leak- age* or shrinkage has taken place, the joint shall be refilled with grout. Carlsbad "A" Steel Pipe Stds. - 8 (b) The joint exterior shall be thoroughly cleaned and a prime coat of Union Bituminous Primer or approved equal shall be applied. After the prime coat has dried (.% to 2 hours)* a hot sling coat (350° to 400° F.) of Union Pipe Dip or approved equal shall be applied* and the joint space shall be filled with the bituminous material. The joints shall then be wrapped as provided herein for pipe coating. C-2.3. Flanged Joints; Flange faces and gaskets shall be thoroughly cleaned just prior to jointing. Following tightening of the bolts* all exposed metal surfaces shall be cleaned* primed* and coated with two (2) coats of hot asphalt. Primer shall be Union Bituminous Primer or approved equal, and asphalt shall be Union Pipe Dip* or approved equal. The primer shall be allowed to dry (£• to 2 hours) prior to applying the first hot sling coat of asphalt. The second hot sling coat of asphalt shall not be applied until the first has been allowed to cool. Care shall be taken to insure that all exposed metal sur- faces are coated. C-2.4. Dresser Type Coupling Joints: Just prior to installation* each pipe and for a distance of 6 to 8 inches back from the end shall be thoroughly cleaned to remove oil* dirt* loose scale* rust and other objectionable foreign matter. Flanges* gaskets* and sleeves shall then be assembled on the pipe ends in accordance with the manufac- turer's recommendations. Gaskets* pipe ends* and coupling sleeve flare shall be lubricated with a vegetable soap compound to facili- tate the joining. Coupling sleeves shall be accurately centered over the pipe ends and one pipe end shall touch the other or pipe ends shall touch the coupling sleeve centering stop if the coupling sleeve is so equipped. Bolts shall be tightened to the torque recommended by the manufacturer and the contractor shall provide and keep at the side a torque wrench for checking the torque on the bolts. Prior to applying the asphalt coating specified below, the torque on all bolts shall be checked in presence of the Inspector and* where necessary* shall be adjusted so that all bolts are at recommended torque. All exposed coupling and pipe surfaces shall be primed and asphalt coated as specified for flanged joints in Paragraph C-2.3, above.

Preventing Foreign Matter From Entering the Pipes; At times when the pipe laying is not in progress, the open ends of the pipe shall be closed by a wooden plug or by other means approved by the Engineer. This provision shall apply during the noon hour as well as over night. C-5. Testing; After the pipe has been laid, the pipeline or any valved section of it shall be subjected to a hydrostatic pressure test of seventy-five pounds per square inch (75 Ibs p.s.i.) in excess of the designated working pressure for the Class of pipe being tested. The duration of the pressure test shall be four hours and the test shall be conducted in the following manner: All air shall be expelled from the pipe. To accomplish this, if air valves or hydrants or other outlets are not available, taps shall be made at the high points in the pipeline to expell the air and these taps shall be tightly plugged afterwards. The pressure in the pipeline shall then be pumped up to the specified test pressure. When the test pressure has been reached, the pumping shall be discontinued until the pressure in the line has dropped 50 p.s.i., at which time the pressure shall again be pumped up to the specified test pressure. This procedure shall be repeated until four hours have elapsed from the time the specified test pressure was first applied. At the end of the four hour period, the pressure shall be pumped up to the test pressure for the last time. The leakage shall be considered as the total amount of water pumped into the pipeline during the four hour period including the amount required in reaching the test pressure for the final time. Leakage shall not exceed the rate of twenty (20) gallons per inch of diameter per mile of pipe per twenty-four (24) hours. Any noticeable leak shall be stopped and all defective pipe, fittings, valves and other accessories discovered in consequence of the test, shall be removed and replaced by the contractor with sound material and the test shall be repeated until the total leakage during a test of four (4) hours duration, does not exceed the rate specified above. All concrete anchor blocks shall be allowed to cure for at least five (5) days prior to testing and all mortared joints shall be allowed to cure for not less than three (3) days prior to testing. C-6. Sterilization; Subsequent to the pressure tests and prior to acceptance of the work, the entire pipeline including all valves, fittings and other accessories shall be sterilized in accordance with American Water Works Association "Standard Procedure for Disinfecting Water Mains A.tf.W.A. C-601-54". Carlsbad "A" Steel Pipe Stds. - 10 Treated water shall be retained in the pipes for at least twenty-four (24) hours and a residule at not less than five (5) p.p.m. shall be produced in all parts of the line after the twenty-four (24) hour period has elapsed. During the sterilization process all valves and other accessories shall be operated. After chlorination, the water shall be flushed from the line at its extremities until the replacement water tests are equal chemically and bacteriologically to those of the permanent source of supply. D. Measurement and Payment D-l. Measurement: Measurement for payment for steel pipe water main and fittings will be made along the centerline of the pipe from pipe end to valve flange or to centerline of intersecting pipe as the case may be» as actually constructed complete in place and in accordance with the Plans and these specifications.
