In Part 1 of “9/11: An Architect’s Guide,” Richard Gage, AIA, provides an overview of the most important evidence regarding the destruction of World Trade Center Building 7 (WTC 7), a 47-story high-rise that was not struck by an airplane.
The damage WTC 7 suffered from the collapse of the North Tower was found to be inconsequential. It had fires that were similar to those that have occurred previously in high-rise buildings. Yet it fell symmetrically into its own footprint in the manner of a typical controlled demolition.
In 2008, the National Institute of Standards and Technology (NIST) concluded that WTC 7’s destruction was caused by normal office fires that burned “at temperatures hundreds of degrees below those typically considered in design practice for establishing structural fire resistance ratings.”
Is NIST’s explanation for this unprecedented structural failure valid? Together, we will study the collapse and evaluate which of the two hypotheses — fire-induced failure or controlled demolition — is more consistent with the evidence. Participants will be encouraged to decide for themselves if a new investigation is warranted.
Participants will be able to:
- Describe the characteristics of building fires and the aspects of high-rise design that contribute to make fire-induced failure in steel-framed high-rise buildings a rare occurrence.
- Recognize the distinct features associated with fire-induced failure and the distinct features associated with the procedure of controlled demolition.
- Describe step-by-step the series of structural failures that the National Institute of Standards and Technology found to be the most likely cause of the collapse of World Trade Center Twin Towers and Building 7.
- Analyze the physical evidence and the dynamics of the collapse of the Twin Towers and Building 7 according to how consistent they are with the competing hypotheses of fire-induced failure and controlled demolition.

Live three-part webinar series. Each part is about one hour long, followed by a short Q&A. This three-part series repeats each month.
AIA Course Number: AE911-AAG-L1
1 LU/HSW for each part.
Certificate of Completion: If you would like to request a certificate of the completion, please do so below at the end of the course.
AIA members: To register your attendance and earn learning units, please submit your name, email address, and AIA membership number online when you are asked to do so by the webinar instructor. Architects do not need to attend all three parts to earn learning units for the part(s) they attend.
Professional Engineers - Live Instructor Requirements: Most states with PDH requirements for Professional Engineering registration where live instructors are required will accept a certificate for completion of each of the parts of this course. Check with state licensing requirements.
AIA / Professional Engineers : Most states with PDH requirements for Professional Engineering registration where self study is allowed will accept a certificate for completion for other related courses as described at Continuing Education for Architects.
