Tender For Soil Investigation For Provision Of Defi Offers Md Accommodation At Abohar Milstn; 1 Bore hole dia shall be 150mm. depth of bore shall be decided as per the site condition and may be taken 15 m for N value reaches 50, whichever is earlier. Note : Under this test preferably following results to be provided : (i) Grain size analysis, identification & classification of soil.(ii) Unit weight (bulk density), natural moisture content, liquid limit , plastic limit, Shrinkage limit, Plasticity index, specific gravity. (iii) Dry density, degree of saturation of soil. (iv) Free swelling index & swelling pressure if expansive soil is encountered. (v) Shear parameters (C-Ø analysis). (vi) Consolidation test & Permeability test. (vii) Depth of water table below ground level. (viii) Presence of loose soil, if any and its depth. (ix) If weak soil with lesser N value as specified in table-1 of IS 1893 (Part-I) 2016 is encountered then evaluation of liquefaction potential shall be assessed and remedial action to be adopted shall be specified. (x) SPT test shall be done at 1.0 m interval. (xi) Reccomendation for filling under floor and filling under protection including plinth protection. (xii)Recommendation of SBC at different depth of foundation 1.2m, 1.5m, 1.8m, 2.0m and 2.5m for each building and/or most suitable strata depth for resting foundation as per type of building/Soil investigation details.
