SECTION: GATE / HOIST & ALLIED WORKS. YEAR: 2010-11 Annexure-1.a

ITEM: Provision for Electric sub-station / Demand charges / Lighting fabrication & work areas:

DATA:Generally, contracts provide for arranging HT / LT electric power line within about 1 km distance

from work site by the department. From the departmental bulk supply point laying of further

transmission lines, erection of sub-station, erecting distribution lines and other arrangements

for power supply to various installations will be the responsibility of the contractors requiring

electric power for their works.

For gate / hoist works, generally, cutting / bending / welding operations for most of the parts

are carried out at the contractor's central fabrication yard and fabrcated parts along with the

bought out parts are transported to site of work. Fabrication of some matching parts and minor

modifications to shop fabricated parts / erection / field welding / commissioning are carried out

at specified work site. Therefore, electric power supply arrangements are necessary both at

central fabrication place and erection / commissioning place for gate / hoist works.
