Be it resolved by the Board of Trustees of the: City of Newport Beach that the following specifications to be known as Specifications No. 34 for the construction of a water distributing system for domestic supply and fire protection in the City of Newport Beach be and the same are hereby adopted. NOR[ TO BE DONE . Under these specifications the contractor will be required: 1. To excavate or fill in to such iz extent and In such a manner as may be required by the plans, profiles and cross sections in these specifications, the area in which the improvement hereinafter provided for is to be constructed. 8. To furnish all materials as hereinafter pro - Tided for and required for the construction and completion of the improvement in.a000rdanos with the plane and specifications and all labor, tools and equipment necessary for the perform - ance of said work. 3. To day and install the pipe fittings, hydrants and other appurtenances as hereinafter specified. r l- STANDARD OML 21 NSIONS: All standard steel pipe shall be lap - welded and conform to the following dimensions: - 6 inch nominal diameter pipe shall have an actual external diameter of not less than 6.685 inches, a wall thick nose of not. less than 0.88 of an inch and a weight of not lass than 18.76 lbs. per lineal foot. 10 inch nominal diameter pipe shall have an actual external diameter of not less than 10978 inches, a wall thick- nose of not less than 0.366 of an inch and a weight of not less than 40 lbs. per lineal foot. ALz = ; The steel for the plates in the mam facture of the pipe must be of the beet quality.eoft steel and have a tensile strength of not less than 551,000 lbs. per square inch, plates must be ,free from lamination and surface defects. COAT I N0: All pipe shall be double dipped and coated inside and outside with asphaltum or coal tar. The coating must be - uniformly thick and must have absolute adhesion to the pipe. To prevent a layer of. moisture beneath the coating, the mixture oust .be applied on a perfectly dry surface. The pipe, before apply- ing the coating, must be oleaned of rust and mill scales. TRENQHIXO: All pipe shall be laid in an open trench. The minimum width of excavation for pipes and fittings shall not be _a_ • • - :r, _:,:-less than six' (Winches wider on both sides of pipes or fiLLings, the excavation shall be made.a sufficlen die taws below the depth indioated,;tiy the grade line on the pro- file and shown by the grade atakes not by the engineer to a.l•• low for Lhickaoss of pipes or-fittings,, and of hubs. Should, however, the trench be excavated to a. depth greater than that herein above last mentioned the Contractor shall refill such excess excavation with send. the Contractor shall beat all Limes during the progress of the work keep the trenches and excavations free from water until the baokfilling has been completed. All soft and spongy earth or material below sub- grade not to exceed two (8) feet in depth, shall be removed by the Contractor and replaoed with screened gravel which shall be tamped until solid. LAPIN PiPX: After the trench has been brought to the proper line and grade in the manner above specified, the pipe shall be laid therein in the following manners- Before any pipe is put into place the trench bottom shall be prepared so that each pipe shall have a firm and uni- foas bearing over its entire length. . All adjustment to line and grade must be made by scraping away or filling in the earth under thenbody of the pipe, and not by wedging or blocking up the ends. Mthe joints of all pipes shall be welded together In a good and workmanlike manner, except that the ends of pipes fitting into gate valves or to connections with fire hydrants, shall be threaded and screwed into place. _3_ • • .00 All joints and screw ends must be thoroughly coated in the manner hersibefore described, and all pipe, the coating of which may have been removed for any reason, want be thoroughly coated before covering the pipe. BAOEIPILLING TBEZON: a .. .3 After the pipe laid has been tested as herein- after provided for, the trench shall be baokfilled with the same material exoavated from the trench, and carefully packed and.well raemed with proper tools under and around the body of the pipe and fittings, as well as the fill over the top of the pipe and fittings. Surplus material not required in refilling the trench shall be evenly and uniformly spread over the ground adjacent to the trench.
