56.8:Recovering disturbed samples and preserving the same in air tight sample containers including waxing labelling packing storing including cost of containers as per IS Code.

56.11.a:Compilation of all field data with recommendation for a suitable foundation after conducting necessary lab test (report in triplicate) - Machine boring for 5 bore holes.

56.11.c:Compilation of all field data with recommendation for a suitable foundation after conducting necessary lab test (report in triplicate) - Machine boring - Extra for additional set for bore holes exceeding 5 nos.

OD44718/2025-2026:Conducting Geotechnical Investigation including Sieve Analysis as per IS 2720 (Part 4) and determination of Shear Strength parameters (C-phi values) through Direct Shear/Triaxial shear test/Unconfined compression tests as per IS 2720 (relevant parts). Scope includes oven drying, dispersing/washing of samples, mechanical sieving, plotting of grain size distribution curves, determination of characteristic diameters (D10, D30, D60), calculation of Cu and Cc, and providing empirical estimations alongside physical test results. The rate includes all labor, equipment, consumables, supervision, and submission of a detailed technical report.
