Job summary

BRK INTERNATIONAL PTE. LTD. in Singapore seeks a site geologist/geotechnical inspector to lead field investigations, review geological reports, and ensure piling works align with design assumptions.

You will supervise borehole drilling, record rockhead levels, weathering, and rock socket conditions, monitor groundwater, and prepare accurate logs and daily reports for handover. This role requires close collaboration with geotechnical engineers and construction teams to identify hazards and

Job description

1. 1. Review Geological Reports – Review geological maps, borehole logs, soil investigation reports, and geotechnical data before piling works begin.
2. 2. Conduct Site Inspections – Inspect site conditions and identify geological features that may affect pile installation.
3. 3. Supervise Geological Investigations – Monitor borehole drilling, sampling, and rock coring activities where required.
4. 4. Identify Soil and Rock Layers – Determine and record the types of soil, rock formations, and weathering grades encountered during drilling.
5. 5. Determine Rockhead Level – Record the actual depth of rockhead and compare it with the ground investigation report.
6. 6. Monitor Piling Operations – Observe drilling progress and geological conditions during bored piling and other foundation works.
7. 7. Inspect Rock Socket Conditions – Record rock quality, fractures, weathering, and socket length for review against project requirements.
8. 8. Monitor Groundwater Conditions – Observe groundwater strikes, seepage, and water-bearing layers that may affect borehole stability.
9. 9. Identify Geological Hazards – Detect cavities, boulders, weak rock, fractured zones, and unexpected ground conditions.
10. 10. Verify Actual Ground Conditions – Compare encountered geological conditions with approved borehole logs and design assumptions.
11. 11. Maintain Geological Records – Prepare accurate borehole logs, rock core logs, geological profiles, and daily inspection reports.
12. 12. Report Unexpected Conditions – Immediately notify the geotechnical engineer and site management of significant geological discrepancies.
13. 13. Recommend Further Investigation – Suggest additional drilling, coring, or probing when existing ground information is insufficient.
14. 14. Coordinate with the Project Team – Work closely with geotechnical engineers, structural engineers, piling contractors, and quality control personnel.
15. 15. Prepare Final Geological Documentation – Compile geological observations, actual rockhead levels, rock socket records, and as-built information for project handover.
