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
