SOIL INVESTIGATION WORK FOR PROVISION OF OTM AND ALLIED INFRA AT NAGROTA UNDER GE P NAGROTA.

Amount

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

Manual Boring (i) Mobilisation including Shifting from one bore hole to another bore hole Manual SPT drilling equipment and boring 100 mm dia bore holes 8m deep through any type of soil/rock strata, collection of disturbed and undisturbed soil samples at 1.5 m or 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 8m depth hole (a) 273 Tech Work Shop = 6 Nos (b) JCOs Club = 2 Nos (c) Guard House = 2 Nos (d) Storage Accn for 197 + 273 FWC = 3 Nos (e) MT Garage = 5 Nos (f) MT Stores = 2 Nos (g) STP = 2 Nos (h) Gate Office = 2 Nos Total No. of Holes = 24 Nos

(ii) Evaluation of following index properties of soil through testing of soil samples in approved laboratroy as per relevant parts of IS:2720 (a) Atterberg llimits (Liquid Limit, Plastic limit and Shrinkage Limits) (b) Natural moisture content (c) Wet and dry density of Soil. (d) Soil particle size, 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/sand/rock samples (j) Permeability test (k) Determination of N&C value Any other important soil property relevant to the type of soil encountred.

(iii) 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 1500 mm & 2000 mm from AGL shall also be worked out from each bore hole. Water table if encountered during excavation shall also be reported each for bore hole alongwith soil profile. Expensive soil if encountered during excavation shall also be specified clearly for each bore hole.

(iv) Maintenance of videographic/photographic record of soil exploration/testing events and submitting the same to Engineer-in-Charge. Note :- Preparation and submission of detailed report consisting of following in sextuplicate :- (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, soil classifications and other index properties determined. (d) Evaluation/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, if encountered. (h) Recommendation on drainage of site.

(v) Soil investigation will be got executed through Gp-I consultants in caterory K approved by E-in-C Branch or from firm NABL approved/MES approved/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/Govt Engg. College/Geotechnical Engineer Holding master degree in soil/Geotechnical 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 copoies/photographci evidence to entire satisfaction of GE. No interim RAR payments shall be made to the contractor and he shall have no claim anything extra from MES Deptt. on accout of such embargo on release of peyment to him till satisfactory completion of work.
