provision of pre-engineered accn for officers and airmen at af stn mohanbari ( spl wks ) , the fwg works are to be carried out for soil testing for provn of pre-engineered accn for officers and airmen at af stn mohanbari ( spl wks ) :- ( a ) boring through sand / clay / silt strata from ground level to 6.00 mtrs. ( b ) carrying out standard penetration test in bore holes as is:2131. ( c ) collection of distrubed sample at every 0.5 mtr or change to strata including packing and handling all complete. ( d ) collection of undistrubed soil samples at 1.0 mtr or change of strata including packing and handling all complete as per is2132-1985. ( e ) carrying out laboratory test for :- ( i ) grain size analysis ( ii ) specific gravity ( iii ) bulk and dry density ( iv ) natural moisture content ( v ) liquid, plastic limit and swelling index ( vi ) sher strength parameters ( vii ) chemical test for solubale chlorides and sulphate content. ( viii ) consolidation test parameters. ( f ) the report to include clearly the following parameters :- ( i ) layout of trial pits and bore holes on propossed. ( ii ) recording 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. ( v ) estimation of safe bearing pressure based on safe bearing capacity as per shear criteria and settlement criteria for rectangular foundations of width of 1.5 / 2.0 / 2.5 m in general. the report shall include detailed calculations for sbc. in case of low bearing capacity recommendation may include bearing capacity calculation sbc & settlement calculation for that foundation also. ( vi ) recommendation of sbc and type of foundation. ( vii ) recommendation of pile with pile capacity in case weaker strata in encountered. ( viii ) other relevant recommendations for foundation and improvement of soil if necessary. ( ix ) recommendation of existing soil for backfill purpose. note :-total 04 sets of spiral binded report shall be submitted and cost for same shall be deemed to be included in quoted retes. => limited
