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