SOIL INVESTIGATION AND TOPOGRAPHICAL SURVEY FOR PROVN OF KLP PH I OF TWO PHASES FOR 3 EW BN AT BATHINDA MIL STN

Amount

Soil investigation is to be carried out as per IS :1892 Bore hole dia shall be 150mm, Depth of bore shall be decideded as per the soil condition and may be taken 15m or N value reaches 50, whichever is earlier. Note : Under this test following results also be provided : (i) Grain size analysis, indetification & 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- analysis). (vi) Consolidatioin 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 specification 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 interval. (xi) Recommendation for filling under floor and filling under protection including plinth protection. (xii) For open foundation, calculation of net SBC at 1.5m, 2m, 2.5m, 3.0m from shear analysis as well as SPT value settlement criteria SBC values shall be calculated based on C analysis as well as SPT value. For calculation formula given in IS 6403 shall be used. (xiii) Recommendation regarding type of foundation to be adopted & net SBC/pile capacity to be adopted. Also, recommedation shall be given regarding stability of soil and soil stabilization required, if any. (xiv) 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. (xv) Undisturbed soil samples shall be collected at 1.5m interval and at change of strata. (xvi) Shear Strength using Direct Shear or Tri-axial Test.

Bore hole dia shall be 150 mm. Depth of bore shall be decided as per the soil condition and may be taken 25 m or N value reaches 50, whichever is earlier for OHR.

Chemical analysis of soil and recommedation and type of cement to be used for RCC foundation.

Chemical analysis of ground water (Ground 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.

Topographical survey with total staion instrument for site showing all natural and man made features on the site, preparation plans (maps) showing all permanent features, incl buildings, large trees, pucca & kacha nullas, ditches, nearby road/approaches, railway track, culverts, over transmission lines, ridges, boundary wall, fencing, demarcation line & levels @ 5mx5m grid and estimating earthwork complete, including submission of topo maps and detailed earth work calculation according to Simpsons rule, 06 copies spirally binded alongwith hard and soft copy. Note:- (i) Borehole positioin duly marked on plan and their distance from adjacent prominent reference points. (ii) Plan size of bldgs shall also be marked in the plan. This plan shall be signed by GE, AGE and soil consultant. (iii) Color photograph on A4 size photo paper of the site with the locations of the boreholes duly flagged should be submitted. The photographs should also preferably include any reference structure and the indentification of the same be marked. (iv) A CD containing video evidence of the depth of each borehole and machinery deployed at site lacation will be provided which is inclusive in quoted rate
