Planning-Litigation Support and Expert Witness

YA Group delivers litigation support and expert witness services for construction, global insurance, and re-insurance related disputes worldwide. Our experts are involved in a wide range of high-value, high-exposure matters, including complex contractual disputes and major builder’s risk and business interruption claims in domestic and international markets. As these matters progress toward mediation, arbitration, or litigation, stakeholders often face competing technical narratives, incomplete project records, and intense scrutiny of expert methodology and conclusions.

YA addresses these challenges by delivering independent, well-supported expert opinions grounded in detailed project analysis, sound methodology, and clear cause-and-effect reasoning. Our experts translate complex construction and insurance issues into clear, persuasive narratives that can be effectively evaluated by mediators, arbitrators, judges, and tribunals. Drawing on experience across large, high-stakes disputes, we provide credible opinions that support informed resolution and withstand rigorous examination.

YA Group supports legal counsel, owners, general contractors, subcontractors, insurers, and re-insurers by providing objective expert analysis tailored to dispute resolution and litigation needs. In construction disputes, we assist with claim evaluation, entitlement analysis, expert reporting, and testimony related to delay, disruption, acceleration, and recovery. In insurance and re-insurance matters, we support counsel and claims teams by evaluating schedule impacts, delays, periods of restoration, and causation issues arising from complex losses around the world.

We work closely with legal teams to ensure our opinions align with contractual, policy, and jurisdictional requirements, whether matters are resolved through mediation, arbitration, or formal litigation. Throughout the process, we maintain independence, transparency, and technical rigor to support effective dispute resolution.

YA Group’s experts support high-stakes disputes arising from some of the most complex construction projects and insured losses worldwide. Our experience includes large commercial developments, public infrastructure, healthcare, federal and education facilities, advanced manufacturing, energy and industrial projects, data centers, and high-rise residential construction. We routinely provide expert analysis on matters involving builder’s risk and business interruption claims, including losses placed in international insurance and re-insurance markets, as well as contractual delay disputes between project participants.

Our work often involves concurrent delays, recovery and mitigation efforts, and competing causation theories, requiring careful technical evaluation and clear expert communication. We have assisted clients through mediation and arbitration proceedings and provided deposition and trial testimony in litigation settings. This depth of experience enables YA to help clients navigate complex, multi-party disputes with clarity, confidence, and defensible expert support.
