Soil Test

Soil investigation presents the detail of the site investigation and laboratory tests of the sample drawn at site. The soil investigation comprises of Standard Penetration Test (SPT), Laboratory tests and prediction of the allowable bearing capacity of the site under consideration. The SPT is to be carried out along with drawing out of both disturbed and un-disturbed soil samples at locations and depth as shown in the relevant sections. The objective of the investigation is to determine the soil formation at the project site so as to derive engineering parameters for the design of the foundation of the proposed structures.
The specific objectives of the consulting services are:
* To do the detailed site investigation and geotechnical investigation of the site
* To submit the detailed site and soil investigation report including engineering properties, design parameters, bearing capacity, coefficient of sub-grade reaction etc.
For the purpose of the foundation design and construction of the proposed building, the following data are to be provided
* Type of foundation
* Depth below the ground level at which the foundation is to be placed
* Allowable bearing pressure at the foundation level
* Design parameters of sub-soil strata (sub-soil profile and engineering properties of the soil strata)

The scope of soil investigation is as follows for borehole advancement to variable depths at variable locations:
* Standard penetration tests at 1.5m interval
* Collection of disturbed and undisturbed samples at regular interval or as and when required
* Ground water table observation
* Laboratory test and analysis of data to determine the engineering properties
* Seismic analysis
* Technical report of the investigation work

The tests performed are:
1. Bulk and dry density
2. Moisture content
3. Specific Gravity
4. Grain size/ Hydrometer analysis
5. Atterberg Limits
6. Consolidation Tests
7. Unconfined compression test
8. Drained Direct shear test
