Job description

Qualifications

• 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.

Responsibilities

• 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.

Skill Set

• Geological mapping, core logging, field inspection.
• Rock and soil mechanics.
• Dam design principles and foundation treatment.
• Strong experience in geological mapping, core logging, and geotechnical site investigations.
• Proficiency in classifying rock mass (RMR, Q, GSI).
• Knowledge of geophysical survey methods.
• Familiarity with tunnel excavation methods (NATM/SEM) and rock support systems.
• Understanding of foundation treatment techniques (grouting, shotcrete, anchors, drains).
