As such, UDD has initiated the project titled ‘Preparation of Payra-Kuakata Comprehensive Plan Focusing on Eco-Tourism’. Engineering Geological and Geo-Physical study is one of the important development module of this project. In this development plan, subsurface geological and geotechnical information’s consider as an important tool for a durable and sustainable urbanization. To know the subsurface soil condition of the study area, several Geophysical and Geotechnical surveys will be carried out up to 30 meters depth. To accomplish engineering geological and geo-physical surveys following investigations should be execute: geo- morphological survey; drilling of boreholes and preparation of borehole logs; collection of undisturbed and disturbed soil sample as per standard guide line; conducting standard penetration tests (SPTs); drilling of boreholes and casing by PVC pipe for conducting Down- hole seismic test; conducting Down-hole seismic test, Multi-Channel Analysis of Surface Wave (MASW) and single Microtremor Measurment. Laboratory test of soil samples such as Grain Size analysis, Atterberg Limits determination, Specific Gravity determination, Direct Shear Test, Unconfined Compression strength determination, Triaxial Test, Consolidation Test etc.
