Mobilisation of necessary eqpt and man power to the project site and dismantling of the same of completion of Fd worked from the site.

Provision of two bore hole of 150mm dia in any type of soil upto max 10 mtr or upto refusal (N=100) whichever meet first conducting standard penetration test as per IS 2131-1981 (reaffirmed-2016) test shall be made at not more the 1.5mtr interval or on change of strata whichever is less. (Approximate loc of Boreholes as per att site plan Mark A and B)

Provision of one bore hole of 150mm dia in any type of soil upto max 30 mtr or upto refusal (N=100) whichever meet first conducting standard penetration test as per IS 2131-1981 (reaffirmed-2016) test shall be made at not more the 1.5mtr interval or on change of strata whichever is less. (Approximate loc of Boreholes as per att site plan Mark C)

Conducting following lab test on bore collected soil samples :- (a) Direct/Triaxial Shear Test. (b) Grain distribution curves & pattern in bore holes. (c) Bulk density. (d) Natural moisture content. (e) Water cable (f) Specific gravity. (g) Attending limit. (h) Hydrometer analysis. (J) Liquid & plastic limit. (k) Swelling index.

Completion of laboratory test, collection of data, calcultion of Gross and Net safe bearing capacity and preparation of report on minimum 80 GSM A4 size white paper duly spiral bound in quintuplet duly vetted by any IIT/NIT (Vetting shall not be in the personal capacity of the professor) recommending following data :- (a) Minimum depth of foundation and type of foundation at different depth as perrelevant IS code. (b) Gross and net safe bearing capacity. (c) Recommendation for raft or pile foundation for depth for foundation more that foundation, disgn parameters for pile foundation and cost analysis between raft and pile foundation shall be given. (d) Photographic record of geo exploration as well as testing shall also part of the report. (e) Recommendation as regards possibility of liquifacation of soil in case of sturated or partially saturated losse/uncompacted sandy soil. (f) Swelling index and swelling pressure in respect of black cotton soil and ites depth/layer (if any). (g) Depth of Gr water table (GWT) in peak monsoon (lowest ) and peak summer (higest) after correlation of result with seasonal of water table in the station. (h) Recommendation for filling lunder floors. (j) RL of the ground level/fooundation level wiht ref to a BM should invariably be mentioned in the soil invesgation report.
