Geotechnical Modelling and Analysis
How ground models are built from site investigation data and used to predict soil and rock behaviour for engineering design.
Trench Stability and Excavation Safety
How trench stability is assessed and what support systems — shielding, shoring, benching — prevent collapse during excavation work.
Quarry Geotechnical Services
Geotechnical services across the quarry lifecycle — resource assessment, slope design, stability analysis and monitoring.
Concrete and Aggregate Testing for Construction
Fresh and hardened concrete testing plus aggregate testing explained, covering slump, compressive strength and physical property tests.
Rippability Assessment for Rock Excavation
How a rippability assessment determines whether rock can be excavated by ripping or requires blasting, using seismic and UCS testing.
Marine Geotechnical Investigations
How marine geotechnical investigations are carried out for ports, pipelines and offshore structures, from geophysical survey to lab testing.
Geophysical Methods for Geotechnical Investigations
An overview of geophysical investigation methods — ERT, GPR, seismic refraction and downhole logging — used to complement borehole data.
Geotechnical Data Management and the AGS Format
How geotechnical data is managed and exchanged using the AGS format, including the Australian AGS 4.1.1 AU variant and its data groups.
Sonic Drilling Methods in Geotechnical Investigations
How sonic drilling uses high-frequency vibration to recover continuous, undisturbed soil and rock cores for geotechnical investigations.
