1. Abstract:
The appropriate scope of a geotechnical investigation is a function of the type of proposed land use or project, the soil/ geologic conditions of the project site, and type of permit or approval sought. The geotechnical consultant is responsible for targeting the scope of their investigation, testing, analyses, and documentation to balance these factors. References are given wherever required.
2. Introduction:
The objective of the exploration work was to determine the probable sub surface conditions such as stratification, denseness or hardness of the strata, position of ground water table etc. and to evaluate probable range of safe bearing capacity and shear strength for the structure.
To fulfill the objective, the work carried out is comprises of:
• Drilling one borehole up to the depth of 10.0m below existing ground level in order to know the sub surface stratification, conducting necessary field tests and to collect disturbs and undisturbed soil samples for laboratory testing.
• Testing soil samples in the laboratory to determine its physical and engineering properties of the soil samples, and

• Analyzing all field and laboratory data to evaluate safe bearing capacity and shear strength of the soil for given foundation sizes and necessary recommendations for foundation design and construction.
The structure is located at JDA-13 Location near Balnaba Village, Bhuj
3. Sub Surface Exploration And In-Situ Testing:
The actual investigation work was started on 18/02/2010 and was completed on 19/02/2010. The work was done in the following manner -
