What are the goals of NIST’s investigation into the collapse of the World Trade Center buildings?[/SIZE][/FONT]
[SIZE=-1][FONT=Arial, Helvetica, sans-serif]The goals are to investigate the building construction, the materials used, and the technical conditions that contributed to the outcome of the World Trade Center (WTC) disaster. The investigation will serve as the basis for:[/FONT][/SIZE]
- [FONT=Arial, Helvetica, sans-serif][SIZE=-1]improvements in the way buildings are designed, constructed, maintained, and used; [/SIZE][/FONT]
- [FONT=Arial, Helvetica, sans-serif][SIZE=-1]improved tools and guidance for industry and safety officials;[/SIZE][/FONT]
- [FONT=Arial, Helvetica, sans-serif][SIZE=-1]revisions to building and fire codes, standards, and practices; and [/SIZE][/FONT]
- [FONT=Arial, Helvetica, sans-serif][SIZE=-1]improved public safety.[/SIZE][/FONT]

What are the main objectives of the investigation?[/SIZE][/FONT]
[SIZE=-1][FONT=Arial, Helvetica, sans-serif]The primary objectives of the NIST-led technical investigation of the World Trade Center disaster are to determine:[/FONT][/SIZE]
- [FONT=Arial, Helvetica, sans-serif][SIZE=-1]why and how the World Trade Center buildings 1, 2, and 7 collapsed after the initial impact of the aircraft;[/SIZE][/FONT]
- [FONT=Arial, Helvetica, sans-serif][SIZE=-1]why the injuries and fatalities were so low or high depending on location (by studying all technical aspects of fire protection, evacuation, [/SIZE][/FONT]
[SIZE=-1][FONT=Arial, Helvetica, sans-serif]and occupant behavior and emergency response);[/FONT][/SIZE]
- [FONT=Arial, Helvetica, sans-serif][SIZE=-1]the procedures and practices that were used in the design, construction, operation, and maintenance of the World Trade Center Buildings; and[/SIZE][/FONT]
- [FONT=Arial, Helvetica, sans-serif][SIZE=-1]which building and fire codes, standards, and practices warrant revision and are still in use.[/SIZE][/FONT]

Why is NIST doing this investigation?[/SIZE][/FONT]
[SIZE=-1][FONT=Arial, Helvetica, sans-serif]NIST scientists and engineers are world-renowned experts in analyzing a building’s failure and determining the most probable technical cause. Since NIST is not a regulatory agency and does not issue building standards or codes, the institute is viewed as a neutral, “third party” investigator.[/FONT][/SIZE]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]Additionally, under the National Construction Safety Team Act, signed into law in October 2002, NIST is authorized to investigate major building failures in the United States. The NIST investigations will establish the likely technical causes of the building failure and evaluate the technical aspects of emergency response and evacuation procedures in the wake of such failures. The goal is to recommend improvements to the way in which buildings are designed, constructed, maintained, and used. [/SIZE][/FONT]

In addition to the investigation into the collapse of the WTC buildings, is NIST conducting related research or programs?[/SIZE][/FONT]
[SIZE=-1][FONT=Arial, Helvetica, sans-serif]The investigation is part of a broader NIST response plan to the World Trade Center disaster. In addition to the investigation, NIST also is concurrently conducting two related programs:[/FONT][/SIZE]
- [FONT=Arial, Helvetica, sans-serif][SIZE=-1]a multiyear research and development program to provide the technical basis for improved building and fire codes, standards, and practices; and [/SIZE][/FONT]
- [FONT=Arial, Helvetica, sans-serif][SIZE=-1]an industry-led dissemination and technical assistance program that will provide practical guidance and tools to better prepare facility owners, contractors, designers, and emergency personnel to respond to future disasters. [/SIZE][/FONT]
