NOTE: I) The rate quoted against this item shall include cost of excavation and backfilling of trench of standard width (as per approved drawings) in all kinds of soil for laying Mainline pipe. II)The Mainline work includes and covers the work in all types of crossings viz., roads, drains, minor water courses (MWC), low lying areas, ponds, plant area, underground utilities, pedestrian crossings, etc. except those crossings identified as "Cased", "Submerged", "Shallow HDD" & "HDD" crossings for which relevant item of SOR shall be applicable.

The decision of the Engineer-in-Charge, as to the cost of the material, shall be final and binding on the Contractor. V) In the course of hydrostatic testing of the mainline section, if any defective portion/ pipe/ work is found to be due to a defect in the pipe attributable to the Owner, the Owner shall supply the additional necessary pipes at Owner issue point required for the work free of cost to the Contractor, but the Contractor shall supply all other materials and inputs at his own cost for replacement of pipe section. The Contractor shall be paid a lump sum amount for each such failure (refer relevant clause of Special Conditions of Contract of the tender documents) for the work involved in locating & identifying the defects in the mainline and in their repair/rectification as per the specification. Failure in one or more pipes in a section during a single pressurization cycle shall be considered as a single failure for the purpose of compensation for hydrostatic test failure on account of manufacturing defect.
