 As described in NIST Tech Beat, The National Institute of Standards and Technology (NIST) has submitted to Congress the annual report of activities under the National Construction Safety Team (NCST) Act, which authorizes the agency to conduct technical investigations of major building failures in the U.S. Although NIST did not conduct any new investigations of structural failures during the past year, the 2007 NCST report details significant progress in both the private and public sectors acting on NIST’s previous investigation-driven recommendations for improvement in building and fire standards, codes, and practices. Those recommendations stem from NIST’s investigations into the failure of the two World Trade Center (WTC) towers following the terrorist attacks of Sept. 11, 2001, and The Station nightclub fire in Rhode Island on Feb. 20, 2003, that killed 100 people.
