Halliwell

What Halliwell does

Halliwell is a global forensic engineering and loss consulting firm founded in 1954, specializing in commercial property damage investigation, origin-and-cause analysis, restoration consulting, and expert witness testimony. Its core services span engineering and forensic architecture (civil/structural, geotechnical, mechanical, electrical, building envelope, fire and explosion, meteorology, GIS/GMS), construction services (scope of damage evaluation, restoration estimating, CAT team support), environmental services (Phase I/II site assessment, remediation design, hazardous materials), fire research services (NFPA 921/1033 fire investigation, fire protection engineering, toxicological research), industrial loss services (finite element analysis, computational fluid dynamics for complex petrochemical, power generation, and heavy machinery losses), forensic equipment consulting, and most recently time element and delay analysis for DSU/BI claims.

The business operates a B2B professional services model, billing per assignment on a quote-based engagement basis, with delivery through a network of 45-plus U.S. offices plus operations in Australia, New Zealand, the UK/Ireland, and Malaysia as of May 2025. Customer mix centers on insurance companies and law firms as primary segments, with corporations and government agencies as secondary segments. Technology differentiation rests on standards-based methodologies (NFPA, RICS), credentialed human experts (professional engineers, registered architects, certified building consultants, meteorologists), and advanced diagnostic tooling (infrared thermography, drone imaging, FEA/CFD, dual-polarization radar), rather than on proprietary software products. The firm is wholly owned by McLarens, a global claims services provider, and has executed an aggressive APAC roll-up since 2023, integrating GKA, Fire Research Group, FireTox, Quintons, IMPARTA Engineers, and du Chateau Chun.
