OUR APPROACH
As trusted Engineering professionals since 1979, we understand the importance of accuracy, independence, and clarity in every investigation and report.

We present our findings in a clear, structured, and defensible format, suitable for use in mediation, arbitration, or court proceedings.
FREQUENTLY ASKED QUESTIONS
An Expert Witness report provides an independent, professional opinion on technical issues for legal or insurance purposes. It explains the facts, cause, and implications of a structural or construction-related matter in a clear and objective way.
We can act for either party or as a single joint expert, depending on the needs of the case. Our duty remains to the court, ensuring impartial and evidence-based reporting.
A forensic investigation may include site inspections, testing, material sampling, design review, and analysis to determine the root cause of a defect or failure. Our findings are supported by photographs, drawings, and calculations where appropriate.
