For the study of hydropower projects, the prefeasibility and feasibility studies have the similar study items, however they differ on the complexity. During the pre-feasibility study, a basic assessment of various study items is made, while during the feasibility study, a further detail assessment is made.

Our strengths in hydropower feasibility study are:

1. Topographical surveys and mapping
   1. a. Available maps and Images study
   2. b. Topographical survey
   3. c. Topographical mapping, plotting, reporting and data presentation
2. Hydrological and sedimentation studies
   1. a. Hydrology study
   2. b. Sediment study
3. Geological/Geotechnical Investigation
   1. a. Regional Geology Study
   2. b. General Geology and Geomorphology of the project area
   3. c. Geological conditions, geomorphology of major project components
   4. d. Discontinuity and Rock Mass Classification Survey (only in feasibility study)
   5. e. Geotechnical Investigation (only in feasibility study)
   6. f. Geological Model (only in feasibility study)
4. Construction Materials Survey
5. Seismic Study
   1. a. Tectonic Setting
   2. b. Seismic Zoning
   3. c. Earthquake Catalogue and Historical and Instrumentally Recorded Earthquakes (feasibility study)
   4. d. Project Specific Seismic Hazard Analysis (feasibility study)
6. Selection of Project Components and Project Layout
7. Optimization Study
8. General Layout and design of civil structures (hydraulic designs of civil structures carried out)
   1. a. Selection and design of hydro-mechanical components.
   2. b. Selection and design of Electro-mechanical equipment
   3. c. Power evacuation and transmission line
9. Energy Computation and Benefit Assessment
10. Cost Estimation
11. Construction Planning and Schedule
12. Environmental Study (feasibility study stage)
    1. a. Initial Environment Examination (IEE)
    2. b. Environment Impact Assessment (EIA) (if project area lies within conservation area/national park/wildlife reserves, etc.)
    3. c. Resettlement Study
13. Project Evaluation
    1. a. Economic analysis
    2. b. Financial analysis
    3. c. Sensitivity analysis
14. Presentation Drawings, Maps, Charts and Tables and a Report compiling all these
