The increasing demand of power day by day in the country put power sector to Himalayas to harness the power potential. Utilization of underground space for infrastructure development is picking up momentum day by day. Every infrastructure project requires significant geological and geotechnical investigation for timely completion of projects. Lots of survey and Investigation is carried out to ascertain the geological and geotechnical feasibility of the hydro projects and for preparation of DPR. Construction of large caverns for power house presents challenges in terms of geotechnical engineering. Due to large size structure needs to ascertain behaviour of subsurface rock mass. The exploratory core drilling and exploratory drifts provide vital subsurface information. The subsurface exploratory drilling data provide immense help to understand subsurface information and reveals the subsurface behaviour of rock mass. The prior knowledge of weak feature can provide opportunity to prepare proactive solutions to mitigate these issues and structure design. Authors are proposing simplified techniques to be implemented to understand ground realization and spatial reconciliation of weak zones/features with modern approaches in core logging with special core studies of Sunni Dam and Luhri Hydro Electric Projects Stage-II in Higher Himalayas of Himachal Pradesh.
