- 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.
