Forensic Expert Witness Services


Expert Witness & Dispute Resolution



Because we are a traditional AEC firm that also offers forensic solutions, we practice what we preach. We offer expert services on megaprojects and high-profile real estate and other property or construction claims throughout the globe. Our claims experts offer standard of care, delay, damage, allocation, and environmental opinions on complex disputes.

VERTEX's services that support construction claims often include failure analysis, evaluation of the status of completion of a construction or design project at the time of the default, and review and analysis against claims for the cost of finishing interrupted construction projects. If you are an attorney or in-house counsel with cases involving design claims, construction claims, or property development claims, VERTEX has your expert witness.
