A New York forensic engineering firm working since 1952 from an ISO/IEC 17025 accredited laboratory — an accreditation of the testing itself, not just of the people, and rare among US fire experts. Its electrical, mechanical and structural engineers support independent fire investigators on electrically and mechanically caused fires, and its fire analysts also opine on fire suppression, fire protection engineering and fire spread — which puts the firm on the design-and-installation side of a dispute as well as the cause-and-origin side. Thirteen staff hold the NAFI CFEI credential.
