Amount

Laying and Jointing PVC Pipe. Heading

Transportation of all T&P/Machinery required for & SPT TEST, Split spoon sampler etc. technician, labour upto the sie/location of work at saryu & Ghaghra river and back to laborrtory along with special T&P such as diamond bit drill sampler for taking undisturbed & disturbed soil samples and rock samples recovered in diamond bit drilling process for testing in labortory

Field investigation-Making borehole in the saryu and ghaghra river for tower foundation ( pile/well) for river crossing near ghaghra Distt. Gonda in all type of soil starta with M.S. caging pipe of outer 150 mm dia or more as required as per site conditions by any method suitable for site condition in accordance with IS specification No 1982-1979 and 1498-1970 and conducting standard penetration test in accordance with IS specification No 2131 – 1981 at every 3.0 M approx . or at change of starta of soil as per requirments in each borehole in accordance with IS specification 1892-1978. (Depth of water table as detemine from borehole or from nearest waterwell ) Each Boreholes to be bored upto 30.00 depth. (The rate should include cost of carrying out the following labortory investigation also:- (CSI 28.13) FROM 30 M TO 70 M

Labortory investigations:- All Undisturbed and disturbed soil samples collected in field will be tested in Laboratory and preparation of samples for tests mentioned below, will be done/governed in accordance with IS 2720 (Part 1)-1983.Necessary test shall be conducted and following parametres will be determined as per relavant IS codes
