soil investigation and structural design in r/o addn/altn to radar complex at dinjan , carrying out soil investigation as given below :- boring through sand/clay/soft strata with 150mm pipe from ground level to 10 mtr depth. (a)subsurface investigation. (i) grain size analysis, specific gravity, unit weight and natural moinsture 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 1892. (vii) plate load tests at recommended depth of foundation. (viii) pate load tests at recommended depth of foundation. (ix) cbr values (soaked & unsoaked) & k value for strata. (x)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 basd on field tests. (v)estimation of safe bearing pressure based on safe bearing capacity as per shear criteria and settlement criteria for rectangular.it also include detailed calculation of sbc. note : in case low bearing capacity recommendation may include bearing capacity calculation sbc & settlement calculation for raft foundation. (vi) recommendation for pile with pile capacity in case weaker strata in encountered. (vii)other relevant recommendation for foundation and improvement of soil if necessary. (viii) recommendation of existing soil for backfill purpose. notes for item no 1 : (ii) all the reports/results will be got vetted from any of the iits or govt engineer colleges after approval from ge/engineer-in-charge. , preparation of structural design and architectural drawing for addn/altn to radar complex at 21 fbsu, af under ge (af) mohanbari, plinth area of bldg 132.00 sqm. note :(a)architectural drawing, structural design and drawing included design claculation folder shall be vetted by iit/govt engg college in original. (b)bidder shall have to submit 5 (five) copies of drawing in a3 size and soft copy in cd. (c)completion duration 30 (thirty) from the day issue of job order. , material and labour laying well burnt old sizebricks, straight or curved on plan , laid flat with width equal to length of brick , laid dry over electric cable for protection all as specified. => limited
