Our Work
Projects That Define Our Approach
A selection of projects that demonstrate our integrated, multidisciplinary approach to complex environmental, geotechnical and brownfield challenges across South Australia.

Environmental · Geotech · 3D Modelling
Large-scale metropolitan contaminated land remediation integrating environmental assessment, 3D site modelling, earthworks volume forecasting and community liaison across one of South Australia's most complex brownfield redevelopments.
Trilogy's services included targeted high-resolution soil characterisation, groundwater remediation feasibility, air quality assessment, 3D site modelling, material volume forecasting and tracking, remediation contractor management and regulatory liaison.
17,000+ tonnes of soil diverted from landfill
1,700 truck movements eliminated — 136,000km saved
Environmental · Remediation
Remediation strategy and implementation at one of South Australia's largest former industrial sites — involving PFAS, hydrocarbons, groundwater treatment and large-scale earthworks management in a sensitive coastal environment.
Geotechnical · 3D Modelling
Real-time geotechnical investigation and ground modelling for a complex urban development site with legacy ground disturbance. Investigation strategy adapted in the field as the ground model was updated with incoming data.
Drone Surveys · Environmental
UAV 3D basin survey used to model sludge dam volume and depth relationships, supporting practical capacity planning, operational decisions and future disposal management.
3D Modelling · Geotechnical · Environmental
Large-area 3D geological model integrating investigation data across a 230-hectare complex site to visualise subsurface conditions and guide assessment priorities.
3D Modelling · Environmental
3D model integrating civil service planning, material volumes and environmental constraints to support construction staging, backfill planning and project cost control.
Private developers, state and local government, infrastructure contractors, agricultural operators and asset owners — across SA and QLD.
Brownfield redevelopment, land acquisition due diligence, pre-purchase contamination assessment and remediation for development feasibility.
State and local government infrastructure projects — roads, transport corridors, public land remediation and regulatory compliance work.
Renewable energy (wind, solar, BESS), mine closure, oil and gas decommissioning and industrial site remediation across SA.
