Hydro-electric Power Projects, challenged by the complex and unique geological settings, require an accurate and thorough knowledge of sub-surface information prior to undertaking their design and execution. Geo-physical, modern Topographic & Hydrographic Survey techniques and Geo-technical Investigations are used to evaluate the in situ sub-strata characteristics of sites intended for major river valley and hydro-electric power projects such as dams, tunnels, powerhouses, surge shafts, pressure shafts etc.


TVIPL’s experienced professionals use state-of-the-art equipment and interpretation techniques to capture, collate and analyze the properties of soil or sub-soil on surface or sub-surface profiles. The information thus gathered provides detailed insight into the site conditions and valuable support for efficient and effective designing, and execution of the project with confidence.

Modern site investigation techniques facilitate mapping the project area in real-time global co-ordinate system. Geo-physical investigations enable precise identification of rock anomalies like fractures and faults, the Modulii of Elasticity in Shear and Compression etc., overburden thickness, rippability (excavability) of rock and almost any physical property of the sub-surface strata. These techniques optimize the scope of site investigations and eliminate the unexpected by virtue of continuous information provided, rather than discrete information obtained by conventional boreholes.

TVIPL has in-house equipment consisting of advanced tools for site investigations and surveys intended for catering to all components of Hydro-electric Power Projects involving complex structures like dams, tunnels, powerhouses, surge shafts, pressure shafts, penstocks etc.
