Amount

Items Required:-

(A) Carryout boring,sampling,testing & conducting SPT test as part of soil investigation to ascertain soil profile,bearing capacity as per following requirement up to depth of 15m:- (a) Conduction standard penetration test (SPT) as per NBC IS-1982, 2131, 2132, 1888, 2720, 1904, 6403, 8009, 1498, 4968 and SP-36. The testing shall be made at every change in strata or at the intervals of not more than 1.00mtr whichever is less. The test may be made at least intervals if specified or considered necessary as per 3.31 of IS-2131-1988. (b) Collection of disturbed/undisturbed soil samples from bore hole at an interval of 1.50 mtr or change of strata and conducting test reporting on following soil parameter:- (i) Grain size distribution/Particle size analysis (ii) Atterberg limits and plasticity index (iii) Bulk and dry density (iv) Specific gravity (v) Moisture content (vi) Harmful salt test (In case of sandy soil) (vii) Direct shear test (viii) Unconfined Un-drained test (ix) Consolidation test (x) Determination of internal angle friction C & O values (xi) Differential free swell test and determination of swelling indexes for expansive soil and if black cotton soil found it site then carryout boring upto 25m for pile foundation and provide all data as per above described and recommend the foundation with necessary data for designing the pile foundation. (xii) Chemical analysis of soil and recommendation and type of cement to be used for RCC foundation.

(B) The soil investigation report shall submit completely covering the following in quadruplicate :- (a) Bore log chart showing depth of soil strata. (b) Ground water level minimum and maximum. (c ) Probable maximum and differntial settlement (d) Safe bearing capacity for various sizes of footing at different depth (e) Recommendations for type and depth of foundation (f) Site plan building wise with RL of corner of building (g) Bore hole location w.r.t FFL/Fixed bench mark with CD vide evidence (h) Bearing capacity and depth of foundation w.r.t FFL/Fixed bench mark (j) Suitability of soil for refilling under floor and in trenches. (k) SBC and its calculation based on 'N' value, sheer srength and settlement criteria. (l) Depth of expansive soil and property (if any). (m) Colour photograph of site (on A4) with location of borehole flagged . it should include referrence structure for identification .

Excavation open trial pit of suitable size for easily carryout plate load test and collect the undisturbed soil sample at every 1.00m interval and carryout plate load test at every 1.00m interval and also carryout following test and submit the report in triplicate :- (i) Grain size distribution / particle size analysis. (ii) Atterberg limits and plasticity index. (iii) Bulk and dry density (iv) Specific gravity (v) Moisture content (vi) Harmful salt test (in case of sandy soil) (vii) Direct shear test (viii) Unconfined Un-drained test (ix) Consolidation test (x) Determination of internal angle friction C & O calues (xi) Differential free swell test and determination of swelling indexes for expansive soil. (xii) K-value of soil 0.50m depth and further 1.00m to 5.00m depth at every 1.00m interval. (xiii) Modulus of subgrade reaction

Carryout level survey by using auto level instrument in 5m grid of a ground of size 150m x 270m (approx) and prepare/submit level sheet & contour plan in quatriplicate and also intimate / indicate temparary bench mark on contour plan alongwith soft copy on A2 size (Coloured)

Note:- If additional data other than above data will be required then additional data will be provided to this office without any extra cost.
