Abstract:
This report was prepared to support the analysis of
building and fire codes and practices of the National
Institute of Standards and Technology (NIST) World Trade
Center (WTC) Investigation. This report suppons the
objective of documenting the requirements that governed
the design and construction of WTC 1, 2 and 7. The
purpose of this report is to provide an evolution of the
life safety provisions of the Building Code of the City
of New York (BCNYC) since the design of WTC 1 and WTC 2,
including retroactive provisions for existing high-rise
office towers. ft has been previously established that
WTC 1 and WTC 2 were designed and constructed in
accordance with the BCNYC as enacted by Local Law No. 76
for the year 1968, effective December 6, 1968. The
evolution of the BCNYC begins with a brief history of
the Building Code prior to 1968 and reviews the various
local laws that have amended fire protection and life
safety provisions of the Code from 1968 until the
collapse of the WTC towers on September11, 2001.
