SUB SOIL INVESIGATION : Sub soil investigation as per IS: 1892-1979 (Reaffirmed 2021) including laboratory testing of soil samples for its all characteristics as per relevant IS codes including value of cohesion and angle of internal friction of soil giving bore log chart showing depth of soil strata/profile. SBC shall be based on N values, shear and settlement criteria. SPT shall be carried out for every changes in stratum or at intervals not more than 1.0m whichever is less. Depth of investigation shall be 15.00m or till refusal or N value reaches 50 wherever is earlier for each isolated, conbined/raft foundation. Soil investigation report for each bore hole tested and duly compiling summary of SBC recommended for various buildings in all respect shall be submitted in four folders duly vetted by CSTL/ IIT/NIT . Depth of water table (maximum & minimum) shall be given. Design parameters for soil investigation are as under. The soil investigation reprot shall be include the liquefaction potential of the soil. If the 'N' valuecomes out to be less than 15, the measures to be taken wet the liquefaction potential & settlement of foundation should be incorporated as per reievant IS code. and Soil Investigation Report should be should be vetted by CSTL/ IIT/NIT/Govt Engg College

Perforamce of Standard penetration tests as per IS 2131:1981 on ordinary soil consisiting of clay/silt/sand/ or their mixture at an interval 1.5m or change of strata & collection of samples from bore hles upto depth of 15.00 mtr or refusal (N>50) & conducting laboratory tests i.e. grain size analysis, atterberg limits, cohesion intercept, angle of shearing resistance . Evaluate allowable bearing capacity on shear strength as well as on settlement consideration along with strata bore logs & comprehensive report for the proposed sites. (List of Bldg are as under) (BH-5 to BH-6, BH-8 TO BH-11, BH-17 TO BH-18)

Evaluate allowable bearing capacity on shear strength as well as on settlement consideration along with strata bore logs & comprehensive report for the proposed sites. (List of Bldg are as under) (BH-1 to BH-4, BH-7, BH-12 TO BH-16 and BH-19 TO BH-40)

Topographical Survery :- Carryout Topographical survey by Digital Total Station and DGPS showing all features like trees, culvert, Electric line, Electric Pole, Transformer, Buildings, roads, Sewage lines, Area Drainage, levelling and contouring etc. Preparation of plans (maps) showing all permanent features, including buildings, large trees, pucca & kutcha nallaha, nearby roads/ approaches culverts, over head transmission & communication lines, ridges, boundary wall, fencing, demarcation line & levels etc using Digital Total Station and DGPS digital instrucments and making contour plan, preparation of drawings and calculation of land area and Submission of Hard copies of all data features including AUTO CAD generated file on CD and including transporation charges of men and machinery to site and return back after completion of work including mobilization charges.
