Immediately following the 9/11 attacks, the Federal Emergency Management Agency assembled a Building Performance Assessment Team (BPAT) to analyze six key areas surrounding the events and circumstances that led to the collapse of the two towers and other buildings on fire at the World Trade Center (WTC). The 26-member team was made up of fire protection and structural engineering experts, and included members of the National Institute of Standards and Technology (NIST).
Robert Duval, NFPA regional director and senior fire investigator, joined the BPAT team at the WTC site just weeks after the attacks. NFPA Journal® talks to Robert about his experience with the investigation.
