Report on Sub Soil Investigations for the Proposed Construction of VANIKI MAHAVIDYALAYA (FCRI) AT MUNGER. Job N0. - 180104 Soiltech Consultants House No. 42, Road No. 2, Nehru Nagar, Patliputra, Patna - 800 013. 1 1. INTRODUCTION The subsoil investigations reported herein were taken up to find out the nature of subsoil at the site of the proposed construction and to recommend the capacity and type of its foundation. After certain tests on the soil, as detailed below, the desired recommendations have been made on page 3 of this Report. 2. FIELD WORK The fieldwork consisted of sinking bore holes, collecting soil samples and conducting the necessary field tests. 2.1. Boring Taking guidance from IS: 1892, 150 mm diameter bore holes were sunk at locations shown in the bore hole location map [Appendix-A]. 2.2 Sampling 2.2.1 Undisturbed Soil Samples Open drive samplers of 100-mm diameter and about 450-mm length were used for obtaining undisturbed samples of cohesive soils. The collection, sealing, labeling and transportation of the samples to the laboratory were done as per the IS guide-lines. 2.2.2 Disturbed Soil Samples Disturbed soil samples were collected at suitable intervals of depth (not more than 2.5 m) and at all depths of change in the nature of the subsoil. These samples were sealed in polythene bags with proper identification labels. 2.3 Field Tests 2.3.1 Standard Penetration Tests (SPT) These tests were conducted as per IS: 2131 – 1963. The depth interval between two consecutive tests was 1 to 1.5 m. The tests were located in between the levels at which undisturbed soil samples were collected.

Job N0. - 180104 Soiltech Consultants House No. 42, Road No. 2, Nehru Nagar, Patliputra, Patna - 800 013. 2 3. LABORATORY TESTS Some or all of the following laboratory tests, as necessary, were done on the collected soil samples. Representative soil samples were selected for this from the different soil strata encountered during boring. The tests were performed as per the relevant Indian Standard Codes of Practice. (a) Natural moisture content (b) Bulk density (c) Grain size analysis (using sieves and / or hydrometer) (d) Specific gravity of soil solids (e) Atterberg’s limit tests (liquid, plastic and shrinkage limits) (f) Shear Tests :  [I] Triaxial compression test (unconsolidated – undrained), generally for fine- grained soils  [II] Unconfined compression tests, only on cohesive soils  [III] Direct shear tests, generally for coarse-grained soils (g) Other tests as and when required. 4. PRESENTATION OF TEST RESULTS The field and laboratory test are given in the Appendix B. 5. SOIL STRATIFICATION The twelve bore holes sunk at the site and the results of field and laboratory tests conducted on the collected soil samples indicate that the soil stratification at the site is as describe below. The subsoil is silty clay [type CL/CI] up to the investigated depth of 10.5 m below GL.A layer of gritty silty clay exits from 9.0 to 10.5 m depth Ground water table was struck at about 6.2 m to 7.3 m in January, 2018. 6. FOUNDATION ANALYSIS The safe capacity of foundation of any type and size may be determined on the basis of the soil data given in this Report by using the standard methods of foundation design and following the relevant Indian Standard Codes. In the present case, shallow foundations may be provided. Report on Sub Soil Investigations for the Proposed Construction of VANIKI MAHAVIDYALAYA (FCRI) AT MUNGER.
