NIST is interested in receiving technical comments about the scope of work and technical approach for The draft statement of work for structural analysis of WTC 7.
Background
This solicitation contributes to completion of the first primary objective of the investigation and the objectives of Project 6, Structural Fire Response and Collapse. (See NIST SP 1000-1, under Project 6, Task 6.) Project 6 seeks to determine the structural response of the World Trade Center Building 7 (WTC 7) to impact by debris from the collapse of WTC 1, the fire environment, and any other events that may have occurred, and to identify probable structural collapse mechanisms.
This Statement of Work (SOW) describes analyses that support determination of the location and cause of the initiating event (i.e., the first component or group of components that failed in WTC 7) that led to global collapse, and the subsequent series of component and subsystem failures up to global collapse (including the vertical and horizontal progression of failures up to the point of global instability) that are consistent with the observations from video and photographic records and other evidence.

This draft statement of work is available for review and comment for 5 business days. To be considered, comments must be emailed to wtc [at] nist.gov (wtc[at]nist[dot]gov) on or before January 10, 2006.
