SCHEDULE 'A' PART-I

Mobilization charge for shifting of equipment shifting as per instruction location proper position for testing, arranging labour etc at place in Narangi Cantt, packing up after completion alongwith making good the same as per instruction of Engineer in charge.

Provision of bore hole 150 mm dia all kind of soil max up to the depth of 5m/6m/10m each bore hole collection of sample 1.5m,2m and every 1.50m interval collection of disturbed and undisturbed samples and regular 1.50m interval upto the depth of 6.00m/10m as per direction of department Engineering in-charge as per IS relevant. (i) 5m deep bore hole = 5 Nos. Identification and classifiction of soil based on properties i.e. liquid, plastic limit, natural moisture content,specific gravitiy, bulk and dry density,type of soil grain size stratification of soil, ground water table location and other properties. Evaluation shear parameters of undisturbed soil samples by adopting direct shear TEST. Evaluation of safe bearing capacity with respect of shear failure test and permissible settlement (total and differential) (25 RM)

Provision of trial pit (Size 1.2m x 1.2m x 1.2m) and identification and classification of soil based on property and conducting laboratory tests as per relevent IS.(Each)

Conducting laboratory test on the soil samples as pe IS codes (per bore hole) for different type of foundation with bearing capacity, ground water level details and preparation of report duly vetted by IIT/NIT/Govt engineering college and submission of report (5 copies) with CD 1 (one) copy. The testing report should consist of the following details:- (a) (i) Sieve analysis and Hydrometer tests for identification and classification of soil based on properties and grain size, (ii) Specific gravity of the Soil, (iii) Studies of settlement characteristics of soil based on consolidation tests and liquid and plastic limit, (iv) Stratification of soil for entire depth of bore log including ground water table locations and other properties. Evaluation of shear parameters of undisturbed soil samples by adopting direct shear test, (v) Nature 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, (vi) Test for liquefaction of 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 types of foundation for all structures with bearing capacity/pile capacities. The recommendations will be duly vetted by the vetting agency as per Notes. Submission of all report 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) alongwith recommendation about type of foundation and minimum depth of foundation to be adopted. (ii) Specific suggestion if any for soil treatment if required below foundation/ ground floor/ roads and type of treatment to be carried out. (iii) Bore log diagram duly showing the different layers of strata met alongwith their depths. Notes:- (c) Following points to be included in the SSI report (not comprehensive, appropriate data/information may be added as per requirement:- (i) Introduction, (ii) Objection of the geotechnical investigations, (iii) Details of the proposed structures,(iv) Site conditions, (v) Field investigations, (vi) Laboratory test results, (vii) Soil Profile, (viii) Allowable bearing capacity-based on SPT 'N' values. 'c-ϕ' value and permissible settlement with sample calcuations. complete calculations will be submitted in soft copy in the same CD containing the SSI Report, (ix) Liquefaction analysis with calculations. (x) Foundation alternatives duly tabulated building wise, (xi) Clear recommendations duly vetted by IIT/NIT/Govt Engg College. 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 required Soil improvement matching with the site plan should form part of the recommendations,(xii) Annexures including bore logs, c-ϕ and other data along with clear site plan duly marking buildings and bore holes, photographs of the test at site, (xiii) Ground water table level should be indicated for BHs. Likelihood of water-logging at site must also be checked. (d) 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. (e) All relevent IS code on the subject should be followed and mentioned at appropriate places. (f) Signed copy to be fwd pl.
