About this role

AFRY is one of the largest international power sector consulting and engineering companies with 19,000 experts creating sustainable solutions worldwide. In South East Asia, it leads with offices in Bangkok, Jakarta, Kuala Lumpur, Manila, Hanoi, Singapore, Pune, Noida, and Taipei. The Senior Site/Field Geologist provides advanced geological and geotechnical expertise for dam and hydropower projects.

The role focuses on dam foundations and underground works from pre-feasibility to construction, designing and supervising site investigations including geological mapping. Develop geological/geotechnical ground models evaluating rock material parameters, rock mass parameters, hydrogeological models, and construction materials. Ensure good design, stability, and constructability of dams and underground structures.

Works closely with design engineers, geotechnical specialists, and construction teams to identify, assess, and communicate geological hazards throughout the project lifecycle. Coordinates with civil, geotechnical, structural engineers, contractors, drilling teams, and investigation consultants. Spends time in the office assisting with preparation of design reports.

Supports foundation treatment and ground improvement works including grouting and seepage control. Prepares geological and geotechnical sections of feasibility studies, Geological Data Reports, Geological Interpretative Reports, and Geotechnical Baseline Reports. Ensures compliance with HSE requirements, site safety regulations, local legislation, and international standards amid increasing business growth.

Requirements

Advanced expertise in geological mapping, borehole logging, and core assessment for dam foundations
Proficiency in rock mass classification, rock material parameters, and rock mass parameters evaluation
Experience developing hydrogeological models and sourcing construction materials
Knowledge of geological hazards assessment for underground works like tunnels and caverns
Skills in construction-stage geological mapping, documentation, and ground condition verification
Familiarity with foundation treatment techniques including grouting and seepage control
Ability to interpret geological data for design assumptions and constructability
Understanding of international standards for geological activities in hydropower projects

Responsibilities

Plan, supervise, and interpret geological and geotechnical investigations including surface mapping, borehole logging, core assessment, rock mass classification, groundwater evaluation, and identification of geological hazards relevant to dam foundations and underground works
Provide geological input to the design of dams, tunnels, underground caverns, and powerhouses, including foundation assessment, rock mass characterization, fault and discontinuity analysis, seepage conditions, and ground behavior
Deliver on-site geological support during excavation, tunnelling, and foundation preparation, verifying actual ground conditions against design expectations and recommending adaptations
Support and supervise foundation treatment and ground improvement works, including grouting, consolidation, curtain grouting, and seepage control measures for dam foundations and underground structures
Prepare and review geological and geotechnical sections of feasibility studies, Geological Data Reports (GDR), Geological Interpretative Reports (GIR), Geotechnical Baseline Reports (GBR), and construction-stage reports
Coordinate closely with civil, geotechnical, and structural engineers, and liaise with contractors, drilling teams, and investigation consultants
Communicate geological findings, risks, and recommendations clearly to project stakeholders
Ensure all geological activities comply with HSE requirements, site safety regulations, local legislation, and applicable international standards
