EPMC SERVICES FOR REWARI – KANPUR PIPELINE
SPECIFICATION FOR PIPELINE CONSTRUCTION
4.5.3 The above described additional depth ditching shall be known as "Normal Extra Depth Ditching",
and no extra compensation will be paid.
4.5.4 OWNER may require CONTRACTOR to excavate the trench to additional depth to provide more
cover than is required by "Normal Extra Depth Ditching" where the line crosses swamps or lands
subjected to floods, where additional excavation is required to prevent freezing, to provide clearance
for future installation of tile or drainage ditches, or where the right-of-way easement so requires. Such
extra depth ditch shall be known as "Abnormal Extra Depth Ditch", and CONTRACTOR shall be
compensated the unit price set forth in the Proposal for "Abnormal Extra Depth Ditch". CONTRACTOR
will not be compensated for extra ditch unless 30 metres (100 feet) or more of continuous Abnormal
Extra Depth Ditch is excavated.
4.5.5 CONTRACTOR shall dig the trench to such additional depth necessary to lay the pipeline under
any other pipelines or underground structures, except drain tile, with at least 1 foot ( 0.3 m) clearance.
Where drain tile is encountered, CONTRACTOR shall dig the trench so that the pipeline may be laid
under with a clearance of a minimum of 6 inches (15 cm). When any drain tile is damaged, cut or
removed, it must be temporarily repaired immediately if necessary, at Contractor's expense. At the
time such tile is damaged, the CONTRACTOR shall carefully and immediately mark the location of
such damaged tile by means of a latch securely staked with a bright yellow flag attached thereto. Such
markers shall be kept in place and shall not be removed except by the tile repair crew after tile has
been repaired and such repairs have been inspected and approved by the landowner and the
OWNER.
4.5.6 No blasting shall be allowed without permission of OWNER, and prior notice to landowners,
adjacent landowners and other interested parties. When blasting is necessary for trench excavations,
precaution must be taken to minimize the danger or inconvenience to landowners and tenants along
the line, to telephone lines or other above-ground structures, and to the Owner's or others' existing
pipelines and other appurtenances. Extreme care shall be exercised so as not to scatter loose rock
over the right-of-way and cultivated fields or cause damages to property. If loose rock is scattered,
CONTRACTOR shall pick up such rock to the satisfaction of the landowner and the OWNER.
4.5.7 OWNER desires to reduce to a minimum the required number of bends to lay the pipe to
conform to the contour of the ground and maintain a normal covering. This ditch shall start sloping 100
ft (30 metres) before approaching any road, railway crossing and small water courses and slope out in
the same manner to obtain required depth. It is Owner's intention that the CONTRACTOR shall
eliminate unnecessary bending by operating the ditching machine at various depths rather than by
finishing grading the ditch by hand, whenever practicable.
4.5.8 CONTRACTOR shall provide temporary crossings, wherever necessary, to permit property
owner or his tenant to travel or move his stock and equipment from one point to another on his
property.
4.5.9 No payment will be made for over-excavation.
