soil investigation in r / o addn / altn to bldg no np-65 air force station dinjan under ge ( af ) mohanbari , carrying out soil investigation as given below: - boring through sand / clay / silt strata with 150mm pipe from ground level to 10 mtr depth:- ( a ) surface investigation:- ( i ) grain size analysis, specific gravity, unit wiight and natural moisture content of soil. ( ii ) liquid limit, plastic limit & swelling index. ( iii ) consolidated tests for consolidation properties. ( iv ) shear strength tests for shear strength parameters. ( v ) chemical tests for soluble chloride and sulphate based in local information and experiences. ( vi ) field tests as per appx c of is 1982. ( vii ) plate load tests at recommended depth of foundation. ( viii ) cbr values ( soaked & unsoaked ) & k value for strata. ( ix ) depth of water table if found in bore holes shall to be reported to ge. ( b ) the report to include clearly the following parameters: - ( i ) layout of trial pits & bore holes on proposed site plan. ( ii ) record of boring as per appx d of is 1892. ( iii ) soil / rock properties as per detailed exploration ( table 3 of is 1892 ) . ( iv ) soil properties based on field tests. ( v ) estimation of safe bearing pressure based on safe bearing capacity as per shear criteria and settlement criteria for rectangualr foundation.it also included detailed calculation of sbc. note: in case low bearing capacity recommendation may include bearing capacity calculation sbc & settlement calculation for rart foundation. ( vi ) recommendation for sbc and type of foundation. ( vii ) recommendation for pile with pile capacity in case weaker strata is encountered. ( viii ) other relevant recommendation for foundation and improvement of soil if necessary. ( ix ) recommendation of existing soil for backfill purpose. notes:- all the reports / results will be got vetted from any of the iits or govt engineering collegs after approval from ge. , preparation of structural design and architectural drawing of addn / altn to bldg no np-65 at dinjan under ge ( af ) mohanbari.
