Consultancy for Soil Investigation for Construction of Single In-living Accn and Allied facilities for Officers at 1.75 acre land at Palluruthy, Kochi.

PART -I MOBILISATION & DEMOBILISATION 1. Making necessary arrangement for Mobilization & demobilization for of equipments,tools & plant, personnel etc. required for soil investigation and their removal after satisfactory completion of work, in land including slushy areas.Shifting of entire arrangement from one borehole to another bore hole location and setting of boring /drilling rig as required(03 Nos Bore holes) . PART-II FIELD TESTS 1. Boring 150 mm dia bore holes to any type of soil/Rock to a depth of 75M or upto depth where N >50, whicever is earlier below the ground level by using rotary drill method in terms of IS:1892 (03 Nos Bore holes) (Min depth of boring 60 M). 2. Collection of undisturbed soil sample (UDS) at 3.0m intervals or at any change of stratas in 100 mm bore thin walled tube including waxing, sealing, packing, and transporting to the lab (03 Nos Bore holes). 3. Carrying out standard penetration test (SPT) incl collection of distribution soil samples in bore holes at every 1.50m depth or any change of strata and submit the report with all requisite data (03 Nos bore holes). 4. Collecting water samples from all bore holes.

Part- III (Laboratory Tests as per IS : 1892 (for all 03 Nos bore holes) 1. Conducting necessary (laboratory) tests on all collected samples (for all 3 bore holes) which includes the determination of :- (a) Atterburg limits (b) Natural moisture content (c) Wet and dry density (d) Soil/Particle size using hydrometer analysis (e) Tri-axial shear test C&D (f) Shrinkage limit (g)Consolidation test (h) Specific gravity test (j) Crushing strength of rock samples, degree of weathering (CR Value) and ROD of rock samples (k) Permeability test (l) Chemical analysis on soil samples (m) Chemical analysis on water samples (n) Standard and Modified Proctor's density test (o) Vane shear test (p) Salinity test (q) Grain size analysis,identification & classification of soil (r) Liquid limit, plastic limit, shrinkage limit, plasticity index, Swell pressure, Free Swell Index. (s) Shear parameters (c-phi Analysis) (t) Depth of water table below ground level

6. If hard soil with lesser than N Values as specified in Table- 1 of IS: 1893 (Part-1) 2016 is encountered, then evaluation of liquifection potential shall be assessed and remedial actions to be adopted shall be specified. Scope of Work (i)Multistoried Bldg (Officers single living accn) G+12 (6479.65 SQM) - 1 Block (ii)Security wall - 243 RM
