The laying of pipe will include all operation such as cutting, welding, jointing, fabrication of bends, tees, etc. including lowering and laying in excavated trenches to ensure required level including flushing, cleaning and hydraulic testing complete in all respects to the satisfaction of the Engineer in Charge. The fabricated bends shall have three or four cuts having its radius not less than five times the dia of pipe. The damaged portion of the pipes and special made for parent tube during welding or otherwise shall be provided anticorrosive treatment by applying two coats of anticorrosive bituminous paint over a priming coat as per AWWA specification C-203-1978. The welding electrodes shall be as per IS-814 of Advani, Oerlikon/ L&T or ISI marked make. The rates also includes entire carriage of material Flushing, Cleaning & Hydrolic testing complete to the best satisfaction & direction of Engineer in Charge with in all leads and lifts.( Earth work in trenches will be measured and paid for separately).
