The full length of each section of pipe shall rest solidly upon the pipe bed, with recesses <br />excavated to accommodate bells, couplings, and joints. Pipe shall be firmly set on a good <br />foundation and care shall be taken that pipe does not rest on stones, rock, or any unyielding <br />material. Pipe that has the grade or joint disturbed after laying shall be taken up and re-laid. <br />Pipe shall not be laid in water or when trench conditions are unsuitable for the work. <br />4.) Installation of the sanitary sewer and force main pipe shall be in accordance with the pipe <br />manufacturer’s recommendations. <br />5.)

Prepare a Plan of Operation for the horizontal directional drilled HDPE sanitary force main <br />installation and submit it to the City Engineer for approval. This plan should show the exact <br />procedures to be used in accomplishing the work (including calibration of the <br />transmitter/receiver, geotechnical information, setup locations, plan for storage of pipe to be <br />placed along with traffic control, drilling fluid plan, the horizontal and vertical tracking/plotting <br />of the pilot bore alignment, and handling and disposal of drilling fluids), and shall show any <br />special activities, and other features of the proposed work. A listing of such subcontractors <br />they intend to use as well as major directional drilling equipment or other specialized <br />equipment to be used shall be included with the submittal. <br />2.) All excavations and trenches for verification of existing utilities, installation of fittings and <br />installation of short segment of pipe shall be properly sloped or braced to furnish and provide <br />proper and safe working conditions for the equipment and personnel in accordance with <br />IOSHA requirements as set forth in Indiana Code IC-22-8-4, Section 238. Provide sheeting to <br />protect adjacent structures when the work is close to existing structures or facilities.
