Amount

Bore hole dia shall be 150mm depth of bore shall be decided as per the soil condition and may be taken 15m or N valve reaches 50 whichever is earlier.

Bore hole dia shall be 150mm depth of bore shall be decided as per the soil condition and may be taken 25m or N valve reaches 50 whichever is earlier. Notes for Item No 1 to 2:- (a) Grain size analysis, identification and classification of soil. (b) Unit weight (Bulk density) natural moisture content, liquid limit, plastic limit shrinkage limit. Plasticity index specific gravity. (c) Dry density, degree of saturation of soil. (d) Free swelling index and swelling pressure if expansive soil is encountered. (e) Shaar parameters (C- analysis). (f) Consolidation test and permeability test. (g) Depth of water table below ground level. (h) Presence of loose soil, if any and its depth. (j) If weak soil with lesser N value as specification in table 1 of IS 1893(Part) 2016 is encountered then evaluation of liquefaction potential shall be assessed and remedial action to be adopted shall be specified. (k) SPT test shall be done at 1.0 m interval. (l) Direc shear test and triaxial compression test. (m) Recommendation for filling under floor and filling under protection including plinth protection. (n) For open foundation, calculation of net SBC at 1.5m, 2m, 2.5m 3.0m from shear as well as settlement as SPT value. For calculation formula given in IS 6403 shall be used. (o) If pile foundation are required the depth of pile shall be mentioned and pile capacity in compression, uplift and lateral load shall be given fo 300, 400, 450, 500 dia for under reamed piles and for 450, 500, 550, 600mm dia for long piles. (p) Recommendation regarding type of foundation to be adopted and net SBC/Pile capacity to be adopted. Also recommendation shall be given regarding stability of soil and soil stabilization required, if any. (q) Borehole position duly marked on plan and their distance from adjacent prominent reference points. Plan size of bldgs shall also be marked in plan. This plan shall be signed by GE, AGE and Soil consultant. (r) Bore log details shall be as per appx D of IS 1892 N values depth wise shall also be shown in bore log details. Bore log details shall be signed by GE, AGE and soil consultant. (s) Coloured photogarhs on A4 size photopaper of the site with the locations of the boreholes duly flagged should be submitted. The photograhs should also preferably included any reference structure and the indentification of the same be marked. (t) Undisturbed soil sample shall be collected at 1.5 m internal and at change of strata.

Chemical analysis of soil determination of organic material in soil and recommendation and type of content to be used for RCC foundation.

Chemical analysis of ground water (water to be obtained from bottom of bore hole)

Plate load test for ascertaining SBC at the proposed level of foundation specified for OHR only. Note A CD containing video evidence of the depth of each borehole and machinery deployed at site location will be provided which is inclusive in above quoted rate.
