Today, one month and one day after the Plasco Building incident in Tehran, we are releasing a preliminary assessment of what caused the demise of this iconic 15-story high-rise, which tragically claimed the lives of 16 firefighters and 10 civilians.

Although we're an organization of architects and engineers dedicated to finding the truth about the destruction of the World Trade Center on 9/11, upon reviewing videos of the Plasco Building collapse and observing the improper rush to judgment about what caused it, we determined it was our ethical responsibility to bring our expertise to bear on this matter as well.

We therefore set out to prepare a report that was as comprehensive as possible in as short a time as possible in hopes of helping steer the dialogue in Iran and worldwide toward ensuring an unbiased, science-based investigation into the causes of the tragedy.

The commission that was appointed by Iranian President Hassan Rouhani to investigate the incident—which includes seven engineers and three non-engineers—is now charged with releasing an official report one month from now.

We will be sending our preliminary assessment to every member of that commission as well as to members of engineering faculties and professional associations throughout Iran. We also plan to send it to news organizations in North America and Europe with the goal of getting them to report on this still-developing story.

Receive a Hard Copy and Help the Effort

We are making the report available as a hard copy booklet to anyone who donates at least $10, or $15 for non-U.S. residents, to help pay for the printing of at least 500 copies for distribution. We encourage you to make this modest donation and receive your own copy of our handsome and compelling document, which you can share with those around you.

Thank you for your always-tremendous support!
