Amount

Driling of bore hole of 150 mm dia & depth upto 6 m from ground level through all types of soil excluding rock and rock like hard stratum according to IS 1892-1988 and 1891-1979 (03 Nos). (a) Conduction of Standard Penetration Test (SPT) as per IS 2131-1988 Testing shall be made at every change in strata or at the intervals of not exc 1.5m whichever is less. (b) Collection of disturbed & undisturbed samples at an intervals of not exc 1.5 m. (c) Conduction of laboratory tests on disturbed and undisturbed soil samples after completion of boring as given below :- (i) Particles size analysis and soil classification. (ii) Atterberg's limits. (iii) Water content. (iv) Specific gravity. (v) Bulk density and dry density. (vi) Direct Shear (in case of sandy soils). (vii) Unconfined un-drained test (in case of clayey soils). (viii) C and ɸ values. (ix) Differential free swell test (in case of expansive soils). (x) Chemical analysis of soils and ground water for harmful salt or organic matter. (d) Transportation charges (up and down for equipment ). (e) Submission of soil investigation report complete covering the following in quadruplicate. (i) Bore log chart showing depth of strata and ground water table. (ii) Probable maximum and differential settlement. (iii) Calculations of safe bearing capacity from both shear failure and settlement criteria in accordance with IS 1904-1986, IS 8009 part I(2). (iv) Recommendation of safe bearing capacity at 1.5 m, 2.0 m, 2.5 m etc. alongwith suggestion/recommendation of suitable type of foundation.
