- Bachelor’s degree in Geology, Engineering Geology, or Geological Engineering.
- Master’s degree in Engineering Geology or Geotechnical Engineering (preferred, especially for senior roles).
- Minimum 5–10 years experience in hydropower, dams, tunneling, mining, or large infrastructure projects
- Conduct detailed geological and geomorphological mapping of the project area, including dam site, waterways, intake, and powerhouse.
- Identify and characterize rock types, structural features (faults, joints, fractures), and soil formations.
- Perform assessment of geological hazards (landslides, slope instability, erosion, seismic features).
- Plan and supervise drilling, borehole logging, test pits, geophysical surveys, and in-situ testing (Lugeon, permeability tests).
- Prepare detailed geological logs for core drilling and assist in rock mass classification (RMR, Q-system, GSI).
- Evaluate foundation stability for dam structures, tunnels, surge shafts, and other components.
- Provide recommendations on foundation treatment such as grouting, rock bolting, drainage, and slope stabilization
- Develop geological prognosis for tunnel routes
- Provide real-time geological mapping during tunnel excavation (face mapping).
- Identify potential tunneling hazards (water ingress, squeezing ground, fault zones).
- Recommend excavation methods and support systems based on ground conditions.
- Assess groundwater conditions, aquifer behavior, seepage patterns, and potential impacts on civil structures.
- Recommend groundwater control measures
- Prepare geological reports, hazard assessments, and data summaries for feasibility, design, and construction stages.
- Maintain daily site records and coordinate with design teams to update geological models.
- Ensure compliance with technical specifications related to geological conditions.
- Inspect excavation works, support installation, grouting operations, and slope/rock stability.
- Work closely with civil, structural, and geotechnical engineers for design optimization.
- Support Environmental and Social teams on issues related to geological impacts and community risks.
