Consultancy of Soil Investigation for Provn Of Hangar with Apron Link Taxi track and earth filling at Juhu for 842 SQN ICG

SCOPE OF WORK PART -I MOBILISATION & DEMOBILISATION Making necessary arrangement for Mobilization & demobilization equipments,tools & plant, personnel etc for soil investigation and their removal after satisfactory completion of work in land including slushy areas Note: The rate includes errecting the set up at first borehole location Shifting of entire arrangement from one borehole to another bore hole location and setting of boring /drilling rig as required PART-II FIELD TESTS Boring 150 mm dia bore holes to any depth as per IS 1982-1979 in following any type of soil/strata by using rotary drill method in terms of IS 1892, as shown in site plan. (Boreholes - 16 Nos) (i) Boring and collection of disturbed samples from boring above upto refusal and minimum depth of 3.0m into the rock (Boring depth max 16.00 M fron GL including depth in rock) (ii) Collection of undisturbed soil sample (UDS) at 3.0m intervals or at any change of stratas in 100mm bore thin walled tube including waxing, sealing, packing and transporting to the lab. (iii) Carrying out Standard penetration test (SPT) including collection of disturbed soil samples in bore holes at every 1.5m depth and submit the report with all requisite data. (iv) Collecting water samples from the bottom bore holes.

PART-III LABORATORY TESTS AS PER IS: 1892 (a) Conducting necessary tests on all collected samples which includes the determination of (For all 16 Bore holes) : (i) Atterburg limits (ii) Natural moisture content (iii) Wet and dry density (iv) Soil/Particle size using hydrometer analysis (v) Tri-axial shear test C&D (vi) Shrinkage limit (vii)Consolidation test (viii) Specific gravity test (ix) Crushing strength of rock samples, degree of weathering (CR Value) and ROD of rock samples (x) Permeability test (xi) Chemical analysis on soil samples (xii) Chemical analysis on water samples (xiii)Standard and Modified Proctor's density test (xiv) Vane shear test (xv) Salinity test (xvi) Grain size analysis,identification & classification of soil (xvii) Liquid limit, plastic limit, shrinkage limit, plasticity index, Swell pressure, Free Swell Index. (xviiI) Shear parameters (c-phi Analysis) (xiv) Depth of water table below ground level PART- IV K Values Carrying out K Value test as per IS 9214 (latest), at locations different from bore holes

(iv) Recommondations for open foundations ,SBC at D -1.5m,2m,2.5m,3 m,3.5m &4m considering the size of Building and configuration of the building. (v). Type of foundation with size and depth (vi). Recommondation of foundation report shall include through investigation of chances of Cliff/filled up spot/rock out crop Note: Ht of the Bldg -9.4 Mtrs (vii). If pile foundation are required then depth of pile foundation including dia of pile and pile capacity in compression, uplift & lateral loads shall be given for 300mm dia,400mm dia,450mm dia,500mm dia for underreamed piles and 450mm dia,500,550,600,650,700,750,800mm dia for long piles. (viii)Recommendations regarding type of foundation to be adopted & net SBC/ recommondation of SBC for raft foundation at suitable depth(ie depth of 04m) to be adopted shall be given. (ix)Recommondations shall be given regarding type of foundation to be adopted & net SBC/pile capacities to be adopted be given. DETAILS OF BLDGS (a) Hangar of size 33Mx37M in PEB structure of height 18.00 M at ridge level. (b) Annexe buildings G+3 configuration (c) Hangar of size 31Mx31M in PEB structure of height 18.00 M at ridge level

(d) Annexe buildings G+3 configuration (e) Dispersal area 2600 Sqm (f) Retaining Wall (520.00RM) (g) Underground Sump (h) POL store/CCR Note: (i) Complete report is to be vetted from IIT/NIT/Govt Engg College (ii) The work is very urgent , no extension will be granted in any case
