Transportation & mobilization charges, to and fro, to the site where the soil investigaton is to be conducted

Conducting 150 mm diameter bores according to IS 1892 of 1979 (reaffirmed in 2016) and SP-36. One bore hole of depth 10 m or till refusal

One trial pit of plan size 1.20 m x 1.20 m and 1.5 m deep at centre of building (a) Conducting tests in laboratory for determining following parameters of disturbed/ undisturbed sample of soil collected after boring :- (i) Sieve analysis (ii) Plasticity index (iii) Specific Gravity (iv) Water Content (v) Particle size analysis (vi) Bulk and dry density (vii) Atterberg limit (viii) Harmful salt or organic matter if any (ix) Direct shear test (in case of sandy soil) (x) Unconfined un- drained test (in case of clayey soil) (xi) consolidated test (for saturated soil) (xii) C values (xiii) Differential free swell test in case of expansive soil. (b) Carrying out and submitting Soil investigation report in six spiral bound folders comprising :- (i) Bore Log Chart showing depth of each soil strata encountered with location of bore holes marked on site plan. (ii) Ground water Table (iii) Probable maximum differential settlement. (iv) Safe bearing Capacity based on Shear and settlement criteria. (v) (v) Allowable bearing capacity at depths of 1.50 m, 2.0 m, 2.50 m or more below ground level as required . If rock is met, SBC based on point laod will be reported.
