At the National Institute of Standards and Technology (NIST) Technical Conference on the Federal Buildings and Fire Safety Investigation of the World Trade Center Disaster, Gaithersburg, MD, September, 13-15, 2005, PCA provided comments on NIST recommendations for design and construction of buildings more than 20 stories in height.

PCA recommended the following in addition to other comments:

• Conduct tests on passive fire protection materials to verify that the materials will not be damaged from normal use.
• Revert back to the older model code requirements which did not allow reduced fire ratings for sprinklered buildings.
• Design buildings for enhanced structural integrity (as required by ASCE -7 and ACI 318).
• Design buildings to prevent collapse during or after total burnout.
