Independent opinion, built to withstand scrutiny
Credibility is the product. Every opinion is grounded, documented, and defensible — because it has to be.
An independent, evaluative role
Our function is strictly evaluative. We do not perform the repair work, hold no interest in the claim’s outcome, and render only the opinion the record supports.
Measured against published standards
Opinions are framed against the applicable building codes, the contract and plans, and recognized industry standards — IRC, IBC, ASTM, and ACI — so they hold up under cross-examination.
Retained by both sides, one standard
We work for plaintiffs and defendants alike. The analysis follows the evidence and the applicable standard of care, not the party that retained us.
