Earth work in excavation by mechanical means (Hydraulic excavator) / manual means in foundation trenches or drains (not exceeding 1.5 m in width or 10 sqm on plan) including dressing of sides and ramming of bottoms, lift upto 1.5 m, including getting out the excavated soil and disposal of surplus excavated soil as directed, within a lead of 50 m.

Earth Work :

Soil investigation by boring up to 15.00 mtrs depth in all type of soil/rock strata at various location, performing SPT at 1.50 mtr interval as per IS 2131-1981. Collection of disturbed/ undisturbed soil samples of different strata of soil as per direction of Engineering-in-Charge. Visual and engineering classification sieve analysis and hydrometer analysis, Liquid, plastic and shrinkage limits, specific gravity, chemical analysis and free swell index determination laboratory test to be performed on disturbed and undisturbed soil sample. Bulk density, moisture content, direct shear test, unconfined compression test one dimensional consolidation test and triaxial shear test (un-consolidation, undrained, consolidation- undrained test with measurement of pore water pressure, consolidated drained) laboratory test to performed on undisturbed soil sample. Visual classification water- absorption slope durability, porosity and density, unconfirmed compression test (Both at saturated and in situ water-contest), rock modulus of elasticity and Poisson's ration, Brazilian tensile- strength and point load-strength index laboratory test to be performed on rock samples. Submission of all test reports along with safe bearing capacity of Soil at different levels- in triplicate.
