Abstract

This document describes the goals, objectives, and guiding principles for the NIST-led investigation of the WTC disaster. The NIST investigation plan includes eight projects that provide the focus for the technical work. Project 1 is an analysis of building and fire codes and practices. Project 2 is the baseline structural performance and aircraft impact damage analysis, project 3 is the mechanical and metallurgical analysis of structural steel, and project 4 is the investigation of active fire protection systems. Project 5 involves the reconstruction of thermal and tenability environment, project 6 is structural fire response and collapse analysis, project 7 involves occupant behavior, egress, and emergency communications, and project 8 covers fire service technologies and guidelines. The plan is located on wtc.nist.gov at http://wtc.nist.gov/media/WTCplan_new.htm.
