Abstract:

This report was prepared to support the goals and objectives of the analysis of building and tire codes and practices of the National Institute of Standards and Technology World Trade Center (WTC) Investigation. The report provides a comparison and summary of significant differences between the 1968 Building Code of the City of New York (determined to be the current building code at the time of construction of WTC 1 and WTC 2), the provisions of the New York State Building Construction Code, and the City of Chicago Building Code that were available at that time.
