Conducting standard penetration test as per relevant IS as an interval of 1.50m. (i) Upto a depth of 5.0m - 03 Nos (ii) Trail Pit of size(1.2x1.2x1.2) - 01 Nos Note : (1) In case of variation in Nos and depth of bore holes as given above the same shall be adjusted at Rs. 1100.00 per running meter of bore hole. (2) The cost of all equipment and their charges shall be deemed to be included in the unit rate., Carrying out the following tests on the soil samples as per IS Codes: (a) (i) Steve analysis and Hydrometer tests of identification and classification of soil based on properties and grain size. (ii) Specific gravity of the soil (iii) Studies of settlement charectenstics of soil based on consolidation test and liquid and plastic limit., (iv) Stratification of soil for entire depth of bore log including ground water table location and other properties. Evaluation of shear parameters of undisturbed soil samples by adopting direct shear test (v) Natural Moisture content(NMC), Void Ratio, and porosity, Tri Axial and direct shear test and unconfined compression test of undisturbed samples and bulk, Submerged and Dry density of the soil (b) Compilation of SSI report as per IS (viz. Field and laboratory test results, preparation of reports, Recommendation for different type of foundations, water table) With clear Unambiguous recommendations for type of foundation for all structures with bearing capacity/pile capacities. The Recommendations will be dully vetted by the vetting agency as per Notes. Submission of all reports booklets 05 (Five) copies with CD 01 (one) copy duly indicating the following:- (i) Evaluation of safe bearing capacity of the soil with respect to shear failure test and permissible settlement (Total and differential) along with recommendation about type of foundation and minimum depth of foundation to be adopted. (ii) Evaluation of Liquefecation potential. (ii) Evaluation of K-value. (iv) Specific suggestion if any soil treatment if required below foundation/ground floors/roads and type of treatment to be carried out (v) Bore log diagram duly showing the different layers of strata met along with their depths Notes:- 1 Following points to be included in the SSI report (not comprehensive, appropriate data/ information may be added as per requirement- (a) Introduction (b) Objectives of the geotechnical investigations (c) Details of the proposed structures (d) Site conditions (e) Field Investigations., (f) Laboratory test results (g) Soil profile (h) Allowable bearing capacitiy-based on SPT N values, C-Ø values and permissible settlement with sample calculations. Complete calculations will be submitted in soft copy in the same CD containing the SSI report. (j) Liquefication analysis with calculations. (k) Foundation alternatives duly tabulated building wise. (l) Clear recommendations duly vetted by IIT/NIT/Govt Engg colege. A table showing building name, BH No, depth & coordinates of the BH corrected SPT N values and the recommended SBC and clear recommendation for depth and type of foundation including any soil improvement matching with the site plan should form part of the recommendations. (m) Annexure including bore logs, C-Ø values and indicating for BHs , liklihood of water logging at site must also be checked. 2 If the soil/water has high (more than permissible) contents of sulphate, chlorides or any other deleterious material, the same should be brought out and appropriate recommendations be offered. The required chemical analysis needs to be undertaken for the same. 3 All relevant IS Code on the subject should be followed and mentioned at appropriate places. 4 Signed copy to be fwd pl.
