NIST NCSTAR 1A: Federal Building and Fire Safety Investigation of the World Trade Center Disaster: Final Report on the Collapse of World Trade Center Building 7: Draft for Public Comment
National Institute of Standards and Technology (U.S.)
"This is the final report on the National Institute of Standards and Technology (NIST) investigation of the collapse of World Trade Center Building 7 (WTC7), conducted under the National Construction Safety Team Act. This report describes how the fires that followed the impact of debris from the collapse of WTC1 (the north tower) led to the collapse of WTC7; an evaluation of the building evacuation and emergency response procedures; what procedures and practices were used in the design, construction, operation, and maintenance of the building; and areas in current building and fire codes, standards, and practices that warrant revision. Extensive details are found in the companion report, NIST NCSTAR 1-9 and NIST NCSTAR 1-9A. Also in this report is a summary of how NIST reached its conclusions. NIST complemented in-house expertise with private sector technical experts; accumulated copious documents, photographs, and videos of the disaster; conducted first-person interviews of building occupants and emergency responders; analyzed the evacuation and emergency response operations in and around WTC 7; performed computer simulations of the behavior of WTC7 on September 11, 2001; and combined the knowledge gained into a probable collapse sequence. This report concludes with a list of 13 recommendations for action in the areas of increased structural integrity, enhanced fire endurance of structures, new methods for fire resistant design of structures, enhanced active fire protection, improved emergency response, improved procedures and practices, and education and training."

Citing HSDL Resources

Documents from the HSDL collection cannot automatically be added to citation managers (e.g. Refworks, Endnotes, etc). This HSDL abstract page contains some of the pieces you may need when citing a resource, such as the author, publisher and date information. We highly recommend you always refer to the resource itself as the most accurate source of information when citing. Here are some sources that can help with formatting citations (particularly for government documents).
