Amount

(a) Drill 150 mm diameter bore holes 0 to 08 meter according to IS 1892- 1988 and IS 1892-1979 including transportation charges (up and down for equipment/engineer/mechine etc).

(b) Conduct standard penetration test (S.P.T) as per IS 2131-1988. The testing shall be made at every change in strata at the intervals of not more than 1.5 mtr whichever is less. The test may be made at lesser intervals if specified or considered necessary as per 3.31 of IS 2131-1963

(c) Collection of disturbed soil samples at an interval of 1.35 mtr or change of strata.

(d) Collection of undisturbed soil samples at an interval of 1.35 mtr or change of strata.

(e) Conduct of laboratory tests on disturbed/undisturbed soil samples as per project requirement after completion of boring as given below :-

(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 (if in case of sandy soil)

(x) Unconfined un-drained test (in case of clayey soil)

(xi) Consolidation test (for Saturated soil)

(xii) C values

(xiii) Differential free swell teest in case of expansive soil

(xiv) Unconfined compressive strength of rock (in case of rocky strata)

(xv) Determination of tensile/shear strength of rock (incase of rocky strata)

(xvi) Quality index for rocky starta (in case of rocky starta) (*) In case rock is encountered the boring shall continue upto 1.5 to 2.0 mtr in rock. The firm shall submit the soil investigation report completely covering the following:- (a) Bore log chart showing depth of soil strata. (b) Sub-soil water table

(xvii) Quality index for rocky strata (in case of rocky strata) (a) Probable maximum and differential setellement . (b) Safe bearing capacity based on sheer and settlement criteria. (c) Recommendations for type and depth of foundation will be submitteed on the format held with GE. (d) Site plan building wise with RL of corners of buildings (e) Bearing capacity and depth of Fdn wrt FFL/Fixed bench mark.

Note:- (a) The location of bldg/bores shall be given by GE. (b) Soil investigation report shall be required as per HQ CE Chandigarh Zone letter No 27947/Pat/13/E2 (D) dt 31 Jul 2019 (copy encl osed with Terms & Conditions) (c) The soil report shall be in 3 parts:- (i) Field operations. (ii) Lab testing and sub soil with soil properties. (iii) Foundation considerations and recommendations separately for separate buildings. (c) 05 copies of the report shall be submitted.

Description all as per item No 01 above but upto 12 mtr depth.
