In Part 3 of “9/11: An Architect’s Guide,” Richard Gage, AIA, provides an overview of the most important evidence related to the extreme heat observed both before and after the Twin Towers’ destruction.
As documented extensively in the report issued by the National Institute of Standards and Technology (NIST), molten metal was seen pouring out of the South Tower during the seven minutes leading up to its collapse. Molten metal was also observed in the debris of both buildings, while various other evidence of extreme heat and incendiary chemical reactions have been documented since.
In 2005, NIST concluded that the Twin Towers’ destruction resulted from the combined effects of the airplane impact damage and ensuing fires, both of which are phenomena that fail to account for the extreme heat observed before and after the Twin Towers’ destruction.
Does NIST’s explanation for these unprecedented structural failures explain all of the evidence? Together, we will study the collapses and evaluate which of the two leading 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-L2
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.
