Amount

SOIL INVESTIGATION FOR CONSTRUCTION OF CSD MODEL DEPOT AND MARRIED ACCN AT CHENNAI (ESTIMATED COST Rs.10,42,530.00)

Mobilisation of Mechanical drilling equipment / rig and shifting of entire arrange ment from one bore to another bore hole location and setting of boring/drilling rig as required/directed by Engineer-in-charge (LS)

Boring 150mm dia bore hole to 10 mtr through the following type of strata for Mechanical Laundry. 35 Nos (LS) Note: Depth of bore holes may be taken 10m or N value reaches 50, whichever is earlier in any type of soil/soft disintegrated rock/hard rock for isolated /combined / raft foundation. To ensure that boulders or layers of cementeous soil is not mistaken for bed rock, core drilling to be done to a depth of atleast 1.0m in bed rock in areas where boulders are found & collection/ preparation of rock samples and determination of bulk density, water absorption and compressive strength is done. However the maximum depth of bore hole is 10m in any case.

Collection of undisturbed soil sample at 1.5m intervals or at any change in strata in 150mm bore thin walled tube including waxing, sealing, packing and transporting to the lab.

Carrying out Standard Penetration test(SPT) including collection of disturbed soil samples in bore holes at every 1.5m depth or any change in strata and submit the report with all requisite data.

Conducting necessary tests as per relevant IS codes :-1892/NBC 2005/SP36 on all collected samples which include the determination of:- (Each bore hole ) (a) Atterberg limits- Liquid limit, Plastic limit , Shrinkage limit (b) Wet and dry density, degree of saturation of soil. (c) Unit weight(Bulk density), Natural Moisture content, Plasticity index, Specific gravity (d) Grain size analysis, Identification and classification of soil, Soil particle size distribution using sieve/hydrometer analysis (e) Shear parameter (C-ø Analysis), Tri-axial shear test and C-ø determination. (f) Consolidation test and permeability test (g) Specific gravity test for sand/rock (h) Crushing strength, Degree of weathering(CR value) and RQD of rock samples (j) Permeability test (k) Chemical analysis of ground water sample (min 02samples) (water to be obtained from the bottom of bore hole) (l) Free swelling Index and Swelling pressure if expansive soil is encountered. (m) Depth of water table below Ground level (maximum and minimum) (n) Presence of loose soil if any and its depth (o) If weak soil with lesser N value as specified in Table-I of IS 1893(Part-I):2016 is encountered then evaluation of liquefaction potential shall be assessed and remedial action to be adopted shall be specified. (p) Chemical analysis of soil and recommendation and type of cement to be used for RCC foundation. (q) Recommendation for filling under floors and filling under protection including plinth protection.

Trial Pit of size 1.2m x 1.2mx 2.0m at various locations as directed by Engr-in-Charge - 03 Nos (LS)

Surveying of the area / site (19 Acre) includes details viz:Location of all topo features, Boundary line & angle, boundary diagonal spot levels, road levels, road width and details above ground level. Survey being done by Sokkia Total station. Contour survey spot levels at 10m interval & contour interval at 0.5m incl four colour prints of the drawing covering the survey details incl marking of services and two computerized CD containing the survey drawing details (01 No (LS))

Submission of report in four sets giving site plan showing the test points, sub soil profile, results of field investigations, laboratory test results, calculation of SBC, Comprehensive type of foundation (LS-01).

Surface dressing area approx 19 acres n exc 15 cm deep in any type of soil including cleaning of bushes including vegitation and small plants digging out roots, cutting of trees/ branches by mean meachnical, filling holes and levelling of ground, including removal of unserviceable material to outside MD land and making good the surface for carry out soil investigation and survey etc.

Note: The bidder shall be quote alongwith inclusive of all taxes (including GST)
