Excavation work

The contractor shall be deemed to have made

himself fully acquainted with the full nature &

complexity of the work, the location and

character of the site and means of access to the

site.

31 2002

The rates and work descriptions have to include

all activities and all costs necessary to complete

the work. The erecting, use and dismantling of

necessary working platforms, scaffolding and

related structures have to be included in the

rates. Construction of coffer dams, guide bunds,

sheet piles etc. if required for diversion of the

river in order to get the working space or to

control seepage during excavation shall also be

included in the rates. The relevant drawings are

an integral part of these tender documents. The

contractor has to study all drawings in detail. By

submitting the tender, the contractor is

declaring that he has understood the drawings

and all the works involved and is prepared to

complete all construction work in a competent

manner. Only the highest degree of accuracy

and quality will be accepted.

The Contractor confirms also to be fully aware

of the soil condition. He agrees not to ask for

additional payments due to changed soil

conditions.The word "soil" in this context refers

to all types of soil, earth, rock, stone, sand,

boulders, gneiss, clay, gravels, mica schist and

so on. In other words, the rate quoted for the

soil excavation shall apply for all the excavation

materials; soil, earth, rock - hard and/or soft,

requiring or not requiring blasting. Irrespective

of the type of excavation material, the

contractor shall be paid at the same rate - the

rate quoted by the contractor for 'soil'

excavation. Therefore, while submitting the

rates, the contractor has to estimate the

proportion of various materials (soil, ordinary

rock, hard rock) in the excavation depending on

the site condition and quote accordingly. The

fact that some of the excavation works will be at

the river side, in the river and below the water

level will also not justify any increase in the

costs. It is important that the contractor does

careful study of the site condition prior to

submitting the tender.

33 2004

The excavation shall be paid as Solid Volume.

Solid volume is the volume of excavation

calculated directly from the foundation

dimensions of the structure without

allowance for bulking, shrinkage, wastage,

working space, slope cutting etc. But the

contractor has to be aware of the fact that the

soil cannot be dug vertically and that additional

excavations would be required for getting the

working space around the foundations, slope

cutting etc. and the contractor has to account for

these additional quantities while setting rates

for the excavation works.

Excavation in ordinary/hard rock for

foundations of abutments . Here excavation

means soil and rock cutting up to the level

shown in the drawing. Controlled balsting

would be permitted. The volume of soil

excavation is calculated as solid volume as

per drawings but the contractor has to

consider the fact that it maynot be possible to

excavate the foundation vertically for deeper

foundations and should therefore keep

provisions for slope cutting, working space

etc. in the rates including dewatering by

bailing out or pumping out water. The

loading, offloading and transportation has to be

included in the rate. The quantity is for both

banks.
