Topographical Survey and Geotechnical Investigation work for 3x660 MW Super Thermal Power Plant
M/s. NTPC Limited had proposed the construction of 3x660MW North Karanpura Super Thermal Power Project at Jharkhand and the job of civil work was awarded to M/s. Bharat Heavy Electricals Ltd. For designing of various Foundation Structures coming under this project, it was necessary to conduct a topographical survey and detailed Geotechnical Investigation Work and M/s. Bharat Heavy Electricals Ltd. in turn awarded the job to M/s. C. E. Testing Company Pvt. Ltd., Kolkata. The scope of the geotechnical investigation work comprised of sinking 136 nos. bore holes. The scope also included Trial Pits, Plate Load Tests, Cyclic Plate Load Tests, Pressure Meter Test, Electrical Resistivity Tests, Cross Hole Shear Tests, Dynamic Cone Penetration Tests and Field Permeability Tests. The scope also included conducting Standard Penetration Tests, collecting disturbed samples at regular intervals for identification and logging purposes, collecting undisturbed tube samples at suitable intervals or at change of strata whichever is earlier and testing these in the laboratory. On the basis of field tests and laboratory test results and their analysis thereof, the most suitable type of foundation is suggested.
