April 2005 Public Briefing on NIST's World Trade Center Investigation

The National Institute of Standards and Technology (NIST) will hold a public meeting starting at 1 p.m. (EST) on April 5, 2005, at the Crowne Plaza Times Square Manhattan (1605 Broadway, Times Square B Room) in New York City to present the latest findings from its building and fire safety investigation of the World Trade Center (WTC) disaster of Sept. 11, 2001. WTC Lead Investigator Shyam Sunder will detail the final probable collapse sequence for the two WTC towers, updating the leading collapse hypothesis released last October. He also will discuss what has been learned from three projects within the WTC investigation (analysis of building and fire codes and practices; occupant behavior, egress, and emergency communications; and fire service technologies and guidelines).

Summaries of each of the three reports will be available at the public meeting; full text will be available online at the NIST WTC investigation Web site, Recommendations from these projects, as well as all other projects in the investigation, will be released for public comment at a later date.

If you have any questions, please contact the main NIST WTC office at (301) 975-6051 or via e-mail at wtc [at] (wtc[at]nist[dot]gov).
