PROVN OF BOUNDARY WALL WITH SECURITY LIGHT, POLE, WATCH TOWER WITH SVL CAMERA AND CONTROL ROOM FOR INF BN BAGHBELLA. Determination of safe bearing capacity of soil by mean of boring 100 to 150mm dia 02 holes upto 7 mtr depth/ refusal and performing standard penetration test (SPT) at suitable interval or in case, gravelly/bounder/ rocky strata encountered before 1.5 mtr depth then open pit upto 2m to 3m depth and DCPT as per IS will be concluded upto 7 mtr or till refusal collection of disturbed/ undisturbed soil samples at various depth of bore holes for laboratory testing i.e grain size analysis attenberg limits, natural density, water contents specific gravity, triaxial shear, free swell index cohension and angle of friction, determination of harmful chemical etc evaluation of safe bearing capacity and strength as per IS 1892:2021.

PROVN OF STORE SHED WITH ALLIED INFRA FOR STORAGE OF DRY SUPPLY AT COMP PL AT TANGDHAR. Determination of safe bearing capacity of soil by mean of boring 100 to 150mm dia 02 holes upto 7 mtr depth/ refusal and performing standard penetration test (SPT) at suitable interval or in case, gravelly/bounder/ rocky strata encountered before 1.5 mtr depth then open pit upto 2m to 3m depth and DCPT as per IS will be concluded upto 7 mtr or till refusal collection of disturbed/ undisturbed soil samples at various depth of bore holes for laboratory testing i.e grain size analysis attenberg limits, natural density, water contents specific gravity, triaxial shear, free swell index cohension and angle of friction, determination of harmful chemical etc evaluation of safe bearing capacity and strength as per IS 1892:2021.

(a) Above test shall be include carrying out SPT and collection of disturbed and undisturbed sample as per relevant IS code. The SPT is required to be taken at 1 mtr interval or at every change of stratum. (b) Carrying out laboratory test with the disturbed/ Undisturbed/sampling and find out grain size analysis gradation properties, Natural Moisture Content, Specific gravity, field density, FMC/MDC/OMC permeability shear and UCT test in the Lab including DCPT and UCT test etc. (c) Evaluation allowable bearing capacity/ SBC of soil by analytical methods. (d) Preparation and submission of consolidated report with photographic record of each bore hole/ plate load test record in hard and soft of of each set in 03 folders for the seperate work etc completed. (e) Above items shall be inclusive of mobilisation/ transportation, labour, soil report (03 folders for each work) and all taxes as applicable.

Following aspects/ points may please be included in test report of bore holes:- (a) In soil test report recommendation of SBC should be given for all the bore holes for minimum three depth i.e 1.5,2.00m and 2.50m. (b) Recommendation of footing type & SBC shall be worked out for minimum foundation of 1.50 x 2.50m 2.00 x 2.50m and 2.00 x 3.00m. (c) All testing shall be carried out as per relevant and latest code provisions. (d) Photographic record of Geo-exploration and testing shall also be a part of Records. (e) Depth of ground water table in peak monsoon and peak summer i.e (highest & lowest) and seasonal variation of water table should be mentioned in report. (f) Recommendations for filling under flooring. (g) Recommendation with respect of liquefaction potential of soil in case of saturated or partially saturated loose/ uncompact sandy soil. (h) Swelling index and swelling pressure in respect of BC soil and its depth/layer.
