Our Geotechnical Engineering Expert Witness Service
Expert Reports and Technical Analysis

We provide objective, court-compliant expert witness reports on geotechnical failures, soil conditions, site investigations, and construction practices. Our reports present technical findings in a clear and concise manner, helping legal professionals and non-technical stakeholders understand causation and liability.

Foundation and Earthworks Dispute Support

Disputes often arise from incorrect foundation design, over-excavation, poor compaction or slope instability. Our specialists assess design documents, site data and compliance with relevant standards to determine responsibility and provide forensic clarity.

Drainage, Retaining Walls and Groundwater Impacts

We investigate issues involving retaining wall collapse, groundwater ingress and surface water management. Our assessments consider hydrology, soil mechanics, and construction methodology to establish root causes and remedial needs.

Site Inspections and Documentation Review

We conduct on-site inspections throughout Australia and New Zealand, reviewing bore logs, test results, geotechnical reports and project records. Our assessments align with relevant Australian Standards such as AS 1726 and AS 2870.

Expert Testimony in Legal Proceedings

In arbitration, tribunal hearings, or court, our geotechnical experts provide clear, defensible testimony based on decades of industry experience. We are skilled at explaining technical concepts in a logical, structured and unbiased way.
