Founded in Adelaide, Trilogy Consulting is a rapidly growing multidisciplinary consultancy integrating environmental, geotechnical and drone-based expertise to deliver better outcomes across complex and disturbed sites.
Trilogy was founded on a simple observation: environmental, geotechnical and drone survey work are routinely handled by separate firms — creating gaps, rework loops and unnecessary cost.
By combining these disciplines under one team, we give clients a single point of accountability, faster decision making, and outcomes that are better because the disciplines talk to each other from day one.
Since founding in 2024, we have grown to a multidisciplinary team of 12+ highly qualified and experienced staff while leading remediation strategy across some of South Australia's most complex brownfield redevelopments.
Over 17,000 tonnes of soil diverted from landfill on a single project — eliminating 1,700 truck movements and 136,000km of transport.
Approximately $10 million saved for a client by identifying and managing an unforeseen site condition before it became a cost blowout.
12+ staff across Environmental, Geotechnical, Drone Surveys and 3D Modelling — all under one roof, one contract.
We deliver results through collaboration, integrity, and personalised service. As a boutique firm, we offer agility and leverage our industry network to provide expert solutions with the highest professional standards.
We deliver practical, sustainable and tailored solutions through strong partnerships and focused effort. Our thorough due diligence ensures regulatory compliance, providing clients with the insights needed to confidently manage complex projects.
Where most firms treat environmental, geotechnical and drone work as separate engagements, we integrate them from day one — one team, one model, one deliverable. No handoffs, no gaps, no rework.
