GEOTECHNICAL ENGINEER

Job Description

1. Ground Investigation & Data Analysis

• Plan, supervise, and interpret geotechnical and geological site investigations (boreholes, in-situ testing, lab tests).
• Review and interpret soil and rock data, geological maps, and hydrogeological information to define ground conditions.
• Prepare ground models and geotechnical baseline reports (GBRs).

2. Geotechnical Design & Assessment

• Provide input to tunnel and shaft design including temporary and permanent support systems.
• Perform stability and deformation analyses for tunnels, portals, and deep excavations.
• Design ground support, shotcrete lining, rock bolts, and waterproofing systems based on ground conditions.
• Evaluate tunnel face stability, settlement prediction, and ground-structure interaction.
• Contribute to geotechnical design drawings, calculations, and reports.

3. Construction Support

• Provide on-site geotechnical advice during tunnelling and underground works (TBM, NATM, drill-and-blast, cut & cover).
• Review and approve contractors geotechnical method statements, risk assessments, and monitoring plans.
• Monitor excavation, ground conditions, and instrumentation data (settlement markers, inclinometers, piezometers).
• Assess deviations from expected ground conditions and recommend design or construction modifications.
• Support incident investigations and mitigation of geotechnical issues encountered during construction.

4. Monitoring & Risk Management

• Develop and implement geotechnical monitoring programs to assess ground and structure behaviour.
• Evaluate and interpret monitoring results to ensure stability and safety compliance.
• Manage geotechnical risks and maintain a live geotechnical risk register throughout project stages.

5. Coordination & Documentation

• Liaise with project stakeholders including design consultants, contractors, and client representatives.
• Coordinate with structural, civil, and MEP teams to resolve geotechnical interfaces.
• Prepare technical reports, design summaries, and site memos in accordance with project standards.
• Ensure compliance with project specifications, local codes, and health and safety regulations.

Requirements

• Bachelor's Degree in Civil / Geotechnical Engineering or Engineering Geology
• 3 years of relevant experience in geotechnical.
• Proven experience with underground construction, tunnel excavation, and support design.
• Familiarity with various tunnelling methods: TBM, NATM, drill & blast, or cut-and-cover.
• Proficiency in geotechnical design and analysis software (e.g., PLAXIS, FLAC, Rocscience, GeoStudio).
• Strong understanding of soil and rock mechanics, groundwater control, and earth pressure theories.
• Experience with geotechnical instrumentation and monitoring interpretation.
• Good communication and report-writing skills.
• Ability to work in site environments, sometimes under challenging conditions.
• Able working 6 days per week, 12 shifts
