    ABSTRACT

    In the following pages, is presented the Report with Analysis, prepared from the thorough study of Geotechnical investigation results. The detailed scope of work was decided in consultation with the representatives of clients and consultants. A complete geotechnical investigation work was undertaken to obtain the required subsurface informations to study and define the nature and behaviour of soil, under application of loads of proposed structures. Such informations were obtained through following steps:

    by making test bores, and collecting disturbed and undisturbed soil samples.

    by performing required in-situ tests.

    by testing the soil in laboratory to classify it and to determine the engineering properties of soil.

    An analysis was made to derive the allowable bearing capacity, taking into consideration the settlements and the present soil conditions with the future possibilities. Based on such analysis of the soil properties, the conclusions are made regarding the nature, behaviour and characteristics of soil. Recommendations are also given, after a thorough and careful study of the present soil conditions, regarding the suitability of type of foundation, and regarding the precautions and protective measures to be taken, if found necessary.

    GEOTECHNICAL INVESTIGATION REPORT

    FOR AMARA RESIDENCY AT BODAKDEV, AHMEDABAD

    INTRODUCTION:

    We (KBM Engineering Research Laboratory, Ahmedabad) have carried out complete Geotechnical Investigation, covering field work and tests, laboratory tests and analysis to study and establish the subsoil characteristics of the proposed project site. The principal objective of the exploration work was to determine the soil profile, bearing capacities at various depths for type/design of foundations of structures. The entire field testing was carried out as per relevant IS codes and as per the instructions of the representatives of the clients. The samples collected from various test locations, were sealed, labelled and transported to our laboratory at Ahmedabad. The required laboratory tests were conducted as per relevant IS codes. This report has been prepared after careful study of the field and laboratory test results. The type and depth of foundations, are suggested.

    SECTION I

    SITE CONDITIONS AND NATURE OF INVESTIGATIONS 1.1 LOCATION: The site is located besides Parijat, opposite IOC Petrol Pump, near Judges Bungalow, Bodakdev, Ahmedabad. 1.2 FIELD WORK: 1.2.1 BORING: The exploratory test bore was drilled as per IS:1892 at the location suggested by clients/consultants. The exploratory test bore of 100mm to 150mm diameter was drilled by shell and auger method. The depth of test bore at the proposed location was as mentioned below: TEST BORE

    DEPTH DRILLED (M)

    BH1 12.5

    1.2.2 SAMPLING: 1.2.2.1 Disturbed Samples: Disturbed samples were collected during the boring at a depth 0 to 0.5M below existing G.L. Disturbed samples were also collected where, undisturbed samples were not recovered. The samples were packed in polyethylene bags, labeled and transported to our laboratory at Ahmedabad. 1.2.2.2 Split Spoon Samples: Standard penetration tests were conducted as per IS:2131 at 1.5M interval or any change in stratum, whichever is earlier, and split spoon samples were collected. The SPT blow counts were noted for 150mm penetration of split spoon sampler. The blow counts were terminated when combined blow counts exceeded 50. The tests were conducted after cleaning the bottom of borehole and sampler centrally seated in position in borehole. The samples were packed in polyethylene bags, labeled and transported to our laboratory at Ahmedabad.

    1.2.2.3 Undisturbed Samples: Undisturbed soil samples were collected in 100mm diameter, 450mm long thin walled tubes having area ratio of about 15% as per IS:2132 at 1.5M interval or any change in stratum, whichever was earlier. Undisturbed samples were collected in strata consisting of cohesive soil/partly cohesive soil. Undisturbed samples were replaced by standard penetration test in cohesionless strata or where undisturbed samples cannot be collected in hard clay or partly cohesive soil. However to correlate the shear parameters/consolidation parameters with N-values few undisturbed were attempted up to 3M depth below existing G.L. in hard strata. Immediately on retrieval of sampling tube after collection of sample, both ends were sealed with freshly molten wax. The samples were sealed, labelled and transported to our laboratory at Ahmedabad for testing. 1.3 LABORATORY TESTING: Soil samples were collected, sealed and labeled at the site, and sent to our laboratory at Ahmedabad. The test results are given in Appendix B. 1.3.1 Field Density and Natural Water Content (IS:2132, IS:2720 P-2): The volume and weight of sample in UDS tube were determined for calculation of field density. Before emptying tube, wherever, shear tests were to be carried out, smaller sampling tube of 38mm diameter and about 76mm height were pushed into the sample in the direction of sampling on site. For consolidation tests, consolidation ring was pushed and extruded from UDS tube before emptying the same. Water content of the specimen was determined from representative sample taken from UDS tube by oven drying method. 1.3.2 Grain Size Analysis (IS:2720 P-4): The grain size analysis was carried out by wet sieving using sieves of sizes 19mm, 4.75mm,
