and contain schedules of all pipe, fittings, valves, expansion joints, <br /> hangers and supports, and other appurtenances. Where special fittings <br /> are required, they shall be shown in large detail with all necessary <br /> dimensions. The drawings submitted shall show flanged jointed sections <br /> placed so as to be removable without disturbance to the main pipe <br /> sections. <br /> 4.08 MARKING <br /> A. A 2" wide magnetic I.D. location tape is required over all sewer <br /> laterals. Tape is to be installed 12" below proposed finished grade. <br /> 4.09 INSTALLATION <br /> A. Unless otherwise noted on the drawings or in other sections of this <br /> specification, the pipe shall be handled and installed in strict <br /> accordance with the manufacturer's instructions. The Contractor shall <br /> use every precaution during construction to protect the pipe against <br /> the entry of non-potable water, dirt, wood, small animals, and any <br /> other foreign material that would hinder the operation of the pipeline. <br /> Where the groundwater elevation is above the bottom of the trench, <br /> the Contractor shall provide suitable dewatering. All piping shall be <br /> placed in a dry trench, unless the Engineer or IRCDUS approves wet <br /> trench installation. <br /> B. Depth of Cover and Pipe Elevation: Unless otherwise shown on the <br /> drawings, or otherwise authorized by the Engineer, all pipe shall have <br /> a minimum cover of 36 inches. Contractor shall determine top of pipe <br /> elevation and top of ground elevation for every two joints of pipe <br /> installed using a level. Pipe must have the minimum cover described <br /> above and must be within +/- 0.2 feet of the top of pipe elevation <br /> indicated on the drawings. Installed pipe, which does not meet these <br /> requirements, shall be reinstalled until it does meet these <br /> requirements. Contractor shall record top of pipe and top of ground <br /> elevations and the locations of where these elevations were <br /> determined and submit this information to Engineer. Engineer <br /> reserves the right to have Contractor excavate and check top of pipe <br /> and top of ground elevations to see if they conform to the <br /> aforementioned requirements, at no cost to the Owner. <br /> END OF SECTION <br /> 4 -4 <br /> l �.3,E•s- <br />
