APPENDIX B: NEW YORK CITY BUILDING CODE & NIST RECOMMENDATIONS

The NIST report of 2005 on the World Trade Center Towers made 30 specific recommendations regarding building standards, codes, and practices, as well as the technical aspects of evacuation and emergency response. Cities around the nation, however, model their municipal building codes on the International Building Code (IBC), which is produced and updated from time to time by the International Code Council. The following table summarizes the extent to which the recommendations of the NIST report of 2005 have been incorporated into the 2009 edition of the IBC and the New York City Building Code, effective July 1, 2008.
