Walter McBrier, PE, is a Construction Expert Witness and Licensed Professional Engineer with nearly 25 years of hands-on construction experience spanning heavy civil infrastructure, master-planned communities, hospitality, multifamily, life sciences, and semiconductor capital projects. He works effectively for contractors, owners, developers, sureties, and insurance carriers. Mr. McBrier's goal in every engagement is to reach the earliest honest resolution — he is a strong advocate for mediation and settlement over prolonged litigation.

Litigation Support - Mr. McBrier's practice focuses on construction delay analysis, CPM schedule forensics, cost damages, change order disputes, and expert testimony in state and federal litigation, arbitration, and mediation across the western United States. His methodology is document-first. He withholds judgment until the contemporaneous record speaks — drilling through daily reports, RFIs, change order histories, and CPM schedule updates to find the evidence that tells the true story of a project. He has found case-defining facts buried twenty layers deep in handwritten subcontractor daily reports that no one else bothered to read.

Ideal Client Engagement - Construction litigation attorneys handling complex delay, cost, and schedule disputes who are focused on early resolution and settlement. Contractors, owners, developers, sureties, and insurance carriers involved in construction disputes requiring technically rigorous, credible expert analysis.

Areas pf Expertise:

• Delay Analysis – As-Planned vs. As-Built, Time Impact Analysis (TIA), and Window Analysis, in alignment with AACE 29R-03 and industry best practices.
• Construction Claims Preparation – Comprehensive documentation, cost and damages quantification, entitlement evaluation, and narrative development for both owners and contractors.
• Change Order Disputes – Forensic evaluation of disputed scope changes, productivity loss, acceleration costs, and schedule impacts, supported by detailed calculations and industry expertise.
• Schedule Disruption Analysis – Assessment of critical path shifts, resource inefficiencies, and resulting financial damages across complex projects.

Mr. McBrier founded GCM Group LLC on a single principle: Clarity Before Conflict. What separates Walter from other construction experts is straightforward: he has been in the fire. As Vice President / Project Director at McAlvain Construction, he managed complex commercial projects, negotiated multimillion-dollar change orders, and worked through significant construction disputes — including depositions — from the inside. That lived experience allows him to read a project record the way only someone who has actually run jobs can: feeling what happened, not just analyzing it.
