In case rock is encountered, the boring shall continue upto 1.50 to 2.00 mtr in rock. Recommended SBC should be given for all bore holes, minimum at three depths viz 1.5m, 2.0m, 2.50m. Soil investigation report shall be submitted covering the following Notes :- Note 1 :- (a) Bore log chart showing depth of soil strata (b) Sub soil water table (c) Porable maximum and different settlement (d) safe bearing capacity based on shear and settlement criteria (e) Recommendation for type and depth of buildings (f) Site plan building wise RL of buildings (g) Bearing capacity and depth of Fdn wrt FFL/Fixed bench mark Note 2 :- (a) The location of bldg/bores shall be given by GE. (b) The soil report shall be in 3 parts (i) Field Operations (ii) Lab testing and sub soil properties (iii) Fdn consideration and recommendation for isolated footing, combined footing, raft foundation & pile foundation (c) The report shall be submitted in quintuplicate to this office. Note 3:-(a) The soil Investigation activity of each bore hole will be recorded photographically. (b) Soft copy (CD) containing folder-wise photographs and videos of soil investigation activity for each bore hole should be included. (c) Each report should include signatures and name of the JE-in-Charge who supervised on ground, concered AGE & GE on the recommendation page. (d) Recommendation for filling under floors.
