Amount

Mobilization and demobilization of drilling rig from lab to testing/work site and from testing /work site back to lab.

Mobilization of mechanical drilling equipment and shifting of entire arrangement from one bore to another bore hole location and setting of boring/drilling rig as required /directed by Engineer-in-charge. Digging of bore hole of diameter 150mm in any type of soil/soft rock /hard rock upto 4.00m depth or refusal strata (N>5) which ever is encounteerd earlier by manual drilling as per IS1892-1979 and conducting Standard Penetration Test (SPT) at every 30cm depth interval and every change of strata as per IS 2131-1981 in bore hole. Observation of ground water table and collection of undisturbed and disturbed samples at every 30 cm depth. Conducting necessary tests as per relevant IS codes /NBC 2005/SP 36 on all collected samples which include the determination of (i) Atterberg limits(liquid limit,plastic limit and plasticity index etc.) (ii) Natural Moisture Content (iii) Wet & Dry density (iv) Soil particle size distribution using sieve/hydrometer analysis (v) Tri-axial/Direct shear Tests C&T determination (vi) Shrinkage limit (vii) Consolidation test. (viii) Specific gravity test for sand/rock (ix) Crushing strength of rock samples (x) Permeability test (xi) Free swell index (xii) Chemical analysis of soil (xiii)Chemical analysis of ground water sample(Min 2 samples) (xiv)Determination of organic materials in soil

Conduction K Value test on 75mm dia plate and evaluating the modulus of sub grade reaction at locations all as specified in IS 9214-1979 o as directed by Engineer-in-charge. Note: - 1. Loading shall be done appropriately using loaded trucks; log sheets for each test shall be maintained and submitted separately in each case. 2. The disturbed locations (Earth pits) will have to be filled / levelled / consolidated after the tests to match the adjoining areas.

Conducting laboratory California Bearing Ratio (CBR) test at locations directed by Engineer-in-charge

Conducting plate load test per 25 tonne capacity at locations directed by Engineer-in-charge to determine the ultimate bearing capacity of soil and the likely settlement under a given load.
