Yes. Först Consulting Group provides construction expert witness testimony in litigation, arbitration, and mediation across Virginia, Maryland, and Washington, D.C. Principal Matthew Furlong has provided litigation support since 2014 and prepares opinions anchored to identifiable authorities so they withstand Daubert/Frye-style scrutiny and cross-examination. Reports are structured around a multi-source breach test — for residential structural matters this commonly includes the applicable edition of the International Residential Code (IRC), any Residential Warranty Corporation (RWC) or comparable warranty standard, NAHB Residential Construction Performance Guidelines, and relevant state statute and local jurisdictional guidelines — so each opinion is traceable to a published standard rather than to unsupported assertion.
