Carrying out 100% radiographic inspection (by X-Ray) of all field weld joints for initial 1(one) Km in each Mainline Spread, Crossings and other specific locations as per Specifications and Special Conditions of Contract (SCC) and 20% radiographic inspection (by X-Ray) for the balance portion (excluding crossings and other specific locations) and destructive testing of one weld joint in each Spread as per specification and direction of Site Engineer, with mandatory minimum percentage by Digital Radiography (Computed radiography) technique as specified in the Special Conditions of Contract (SCC) for the tender including providing Crawler type Automatic X-Ray machine and external X-Ray machine, and all other requisite equipment, labour, supervision, materials, approved films, imaging plates, scanners, CR software, approved consumables, all facilities and personnel to process, develop, examine and interpret radiographs (by qualified and experienced Radiography Inspector), providing all facilities to Owner's representative(s) for examining radiographs and other tests as required, carrying out repair of weld-joints found defective, carrying out re-radiography and other tests as required on repaired joints, etc., - Carrying out coating of all field weld joints, by qualified coating insulators, including supply of approved joint coating materials, providing all equipment, materials and consumables necessary to carry out the job as per manufacturer's recommendation, - Installation of hot-pulled bends at required locations in mainline (bends to be fabricated from Owner-supplied bare pipes) including cutting, bevelling, fitment, coating the bare bend pipe with approved heat shrink sleeves, - Carrying out holiday detection, at specified voltage level corresponding to coating type and as per specifications, and repair of coating, if any, -Laying pipeline by open-cut method at crossings viz., cart-track, village road, metalled/ un-metalled roads, minor water courses (MWC) etc.,(except crossings identified as "Cased", "Submerged" & "HDD" crossings ) and restoration of the crossing site to original condition including performance of additional works for strengthening of banks of water courses etc., - Lowering the pipeline in trench, tieing-in, backfilling with excavated earth and/or other suitable soil (top soil stored separately during trenching shall be backfilled on top of the ditch) as directed by Site-Engineer, - Carrying out air cleaning, gauge pigging and hydrostatic testing (to specified pressure) of the complete pipeline (excluding those HDD crossing sections not under the scope of this tender) including providing 'pre-testing' of designated sections as approved by Engineer-in-Charge, providing all equipment, pumps, fittings, instruments, dead weight tester etc. and services, supervision, labour, consumables, testing of water, supply & injection of corrosion inhibitor, locating leaks, if any, and rectification of defects attributable to Contractor, re-testing after rectification etc. and cleaning the pipeline section after successful hydrotesting, - All tie-ins, including tieing-in with HDD sections under this tender and also with HDD sections not covered under this tender (tie-ins with HDD sections not under this tender shall be paid separately as per relevant item of SOR), - Obtaining work permits/ NOC from various authorities having jurisdiction before execution of work and complying with all stip ulations/ conditions/ recommendation of the said authorities - Supply and installation of 1.0 mm thickness & width (D+300) warning mat/ mesh over entire pipeline as per relevant specification - Final clean-up and restoration of ROW/ construction corridor, field bunds etc., obtaining NOC from statutory authorities (as required) and obtaining NOC from respective land owners in respect of final restoration of their land etc, disposal of debris and returning surplus material to designated disposal areas/ storage location, as directed by Engineer-in-Charge, restoration of land, facilities and boundary wall etc. for facilities dismantled/ damaged by Contractor during construction, -
