SOIL INVESTIGATIGATION

Testing of Safe bearing capacity of soil and submission of detailed report consisting of following detailed here under

Manual Boring

Mobilisation including Shifting from one bore hole to another bore hole Manual SPT drilling equipment and boring 100 mm dia bore holes 700mm deep through any type of soil oblique rock strata and collection of disturbed and undisturbed soil samples at closer intervals on change of strata using sampling equipment as per IS 1892 and undertaking standard penetration test as per IS 2131 or DCPT (Dynamic Cone Penetration test) depending upon the soil strata as per IS 10042 for the following scope

Location for 700 mm depth hole 15 Nos at 03 Igools 05 for each Igloos

Evaluation of following index properties of soil through testing of soil samples in approved laboratroy as per relevant of parts of IS 2720 (a) Atterberg llimits Liquid Limit and Plastic limit and Shrinkage Limits (b) Natural moisture content (c) Wet and dry density of Soil (d) Soil particle size and distribution using sieve analysis and hydrometer analysis (e) Shear test for determination fo shear strength cohesiveness (f) Crushing strength of rock samples (g) Shrinkage limit (h) Specific gravity test for soil oblique sand oblique rock samples (j) Permeability test (k) Determination of N and C value Any other important soil property relevant to the type of soil encountred

Submission of soil investigation report shall be with recommendation of type of foundation and SBC of soil at a suitable depth from AGL In case of sloping ground on which bore hole is being done the AGL should be the level of prepared ground after cutting of slope for construction of building as decided by Garrison Engineer SBC of soil at a depth of 700mm from AGL shall also be worked out from each bore hole Water table if encluntered during excavatin shall also be reported for bore hole alonswith soil profile Expensive soil if encountered during excavation shall also be specified clearly for each bore hole

Maintenance of videographic oblique photographic record of soil exploration oblique testing events and submitting the same to Engineer in Charge Note Preparation and submission of detailed report consisting of following in pentuplicate (a) Layout plan of proposed works and relative positions of Test locations (b) General geography and overview of soil strata and soil properties (c) Bore log charts and soil classifications and other index properties determined (d) Evaluationn oblique calculations of SBC and other soil parameters as per relevant IS code (e) Recommendations of type of foundations depth and SBC to be adopted for foundation designs (f) Any soil improvement reqd prior to construction of foundation (g) Depth of groound water table and if encountered (h) Recommendation on drainage of site

Soil investigation will be got executed through Gp I consultants in caterory K approved by E in C Branch or from firm NABL approved oblique MES approved oblique State Govt approved agency documentary proof of aforeaid approval shall be produced to GE for his go ahead in writing before execution of work under the supervision of a Geotechnical soil engineer and report will be got vetted by IIT oblique Govt Engg College oblique Geotechnical Engineer Holding master degree in soil obliqueGeotechnical Engineering Note The payment shall be made to the contractor on satisfactory completion of all the activities detailed and after submissiion of all documednts in hard and soft copies oblique photographci evidence to hte entire satisfaction of GE No interim RAR payments shall be made to the contractor shall not claim anything extra from MES Deptt on accout of such embargo on release of payment to him till satisfactory completion of work

Testing of Safe bearing capacity of soil and submission of detailed report consisting detailed as above
