JOB ORDER FOR SOIL INVESTIGATION OF PARA-35 WORKS OF DWP 2007 FOR PROVN OF GABION STRUCTURE TO PROTECT OSQ HILL AT CIJW SCHOOL VAIRENGTE UNDER GE SILCHAR

Amount

Mobilization/Transportation erection and dismantling of all required equipment at proposed site including deployment and shifting of suitable personal for effective soil investigation as directed.

Carrying out soil investigation as per relevant IS codes complete all as specified and directed including the following :- (a) Boring 150mm dia hole at various location as shown at site by Engineer -in-charge in any kind of soil but excluding rock, collection of undisturbed sample at every 1.00m depth collection of disturbed sample at suitable depth as required at site. Conduction standard penetration test as per relevant IS at an interval of 1.50m as under :- (i) Upto a depth of 10m-02 bore holes.

Carrying out following laboratory test on the soil samples as per IS Codes :- (i) Sieve analysis and hydrometer test for identification and classification of soil based on properties and grain size. (ii) Specific gravity of the soil. (iii) Studies of settlement characteristics of soil based on consolidation test and liquid and plastic limit. (iv) Stratification of soil for entire depth of bore log including ground water table locations and other properties. Evaluation of shear parameters of undisturbed soil samples by adopting direct shear test. (v) Natural moisture content (NMC), Void Ration and Porosity, Tri-Axoal and direct shear test and unconfined compression test of undisturbed samples and Bulk, submerged and Dry Density of the soil.

Compilation of SSI Report as per IS viz, Field and Laboratory test result, Preparation of reports, Recommendation for different type of foundation, water table with clear unambiguous recommendation for types of foundation for all structures with bearing capacity / pile capacities. Submission of all report booklets 05 (Five copies with CD 01 (One) Copy duly indication the following :- (i) Evaluation of safe bearing capacity of soil with respect to shear failure rest and permissible settlement (Total and differential) alongwith recommendation about type of foundation and minimum depth of foundation to be adopted. (ii) Specific suggestion if any for soil treatment if required below foundation / ground floor / Roads and type of treatment to be carried out. (iii) Bore log diagram duly showing the dirrerent layers of striate met alongwityh their depths.

Vetting of report from IIT, NIT or any other Govt Engineering College.
