Job summary

BRK PTE. LTD. in Singapore seeks a Geotechnical Site Inspector to review geological reports, maps, borehole logs, and soil investigations before piling works commence.

You will inspect site conditions and monitor drilling, logging, and rock core activities to ensure alignment with project designs. You will record rockhead levels, soil and rock layers, groundwater observations, and any hazards, while coordinating with geotechnical engineers and piling contractors for accurate documentation and

Responsibilities

• Review geological reports, maps, borehole logs, soil investigations and geotechnical data before piling works commence.
• Conduct site inspections to assess conditions and identify geological features that may affect pile installation.
• Supervise geological investigations including borehole drilling, sampling and rock coring where required.
• Identify soil and rock layers and record types encountered during drilling.
• Determine rockhead level and compare with ground investigation data.
• Monitor drilling progress and geological conditions during bored piling and other foundation works.
• Inspect rock socket conditions and record rock quality, fractures and socket length.
• Monitor groundwater conditions including strikes, seepage and water-bearing layers.
• Identify geological hazards such as cavities, boulders and fractured zones.
• Verify actual ground conditions against borehole logs and design assumptions.
• Maintain geological records including borehole logs and geological profiles.
• Report unexpected conditions to geotechnical engineer and site management.
• Recommend further investigations when ground information is insufficient.
• Coordinate with project team including geotechnical engineers, structural engineers and quality control.
• Prepare final geological documentation for project handover.

Job description

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