Addl Soil Investigation for OTM Accn for 3 Corps Inteligence and Surveilance Unit 3 CISU and Addl Soil Investigation for KLP Accn of Inf Bn Phase II for RCC Retaining Wall and Relocated Blocks at Rangapahar

Amount

Mobilization / Transportation, erection and dismantling of all required equipment at proposed site including deployment of skilled and suitable personal for effective soil investigation as directed.

Carrying out Soil Investigation as per codes complete all as specified and directed including the following:- (a) Boring 150 mm dia hole at various locations as shown at Site by Engineer- in- Charge in any kind of soil but excluding rock, Collection of undisturbed samples at every 1.00 m depth, Collection of disturbed Samples at suitable depth as required at site. Conducting Standard penetration test as per relevant IS at an interval of 1.50 m as under:- (i) 3 CISU (aa) 01 No Borehole upto depth of 10 m, 1 x 10 = 10 RM - (A) (ii) Inf Bn Ph-II (aa) Pocket I : 09 No Borehole upto a depth of 25 m/upto Refusal, 9 x 25 = 225 RM - (B) (ab) Pocket II : 04 X Re-located blocks of Inf Bn Ph-II, 04 No Borehole upto a depth of 10 m, 4 x 10 = 40 RM - (C) Total = (A)+(B)+(C) = 10+225+40=275 RM

Carrying out the following laboratory tests on the soil samples as per IS Codes :- (a) (i) Sieve analysis and Hydrometer tests for identification and classification of soil based on properties & grain size. (ii) Specific gravity of the Soil. (iii) Studies of Settlement characteristics of soil based on consolidation tests and Liquid and Plastic limits. (iv) Stratification of Soil for entire depth of bore log including ground water table locations (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. (vi) Detailed soil investigation including liquefaction potential settlement analysis, slip circle and stability analysis.

(b) Compilation of SSI Report as per IS Vix. Field and laboratory test result, preparation of reports. Recommendation for different type of foundation, water table with clear unambiguous recommendations for types of foundation for all structures with bearing capacity/pile capacities. (i) Submission of all report booklets 05 (Five copies with CD-01 (One) copy duly indicating the following:- (aa) 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. (ab) Specific suggestions if any for Soil Treatment if required below foundation / ground floor / roads and type of treatment to be carried out. (ac) Bore log diagram duly showing the different layers of strata met alongwith their depths.
