Soil Investigation

Amount

Mobilization & de-mobilization of resources at the site comprising of instrument, equipment, drilling Rig and personnel at the proposed site for collection of field data and execution of in situ tests including the expenses towards transportation of soil samples, collected during drilling, to soil mechanics laboratory, including supply of all material, labour and T&P etc required for proper completion of work as directed by Engineer-in-charge.

Exploratory drilling 150 mm dia, of boreholes up to a maximum depth of 20m or up to refusal (Refusal shall be defined when 'N' value reached 100 for penetration of 300mm), whichever met earlier, by percussion method in all type of overburden soil excluding rock, Conducting Standard Penetration test as per IS: 2131 in the boreholes at an interval of 1.50 meter in depth and at every change of strata form borehole with Collection of Undisturbed soil samples form all boreboles at intervals of 3.0 meter in depth and at every change of strata from borehole including Collection of Disturbed soil samples in the boreholes at an interval of 1.50 meter in depth and at every change of strata from borehole, including Measurement of Ground Water Level after completion of each borehole and collection of water samples from each borehole, minimum 1 ltr. Each. including supply of all material, labour and T&P etc required for proper completion of work as directed by Engineer-in-charge.

Conducting of Following lab tests of each of the soil sample collected vide item No. 3 above, on each bore hole, including supply of all material, labour and T&P etc required for proper completion of work as directed by Engineer-in-charge:- (i)Natural Moisture contents as per IS 2720 (Part-lll)-1973.RA 2015 (ii)Specific gravity test (fine grained and Coarse grained soil) as per IS 2720 (Part-III-sec 1)-1980.
