9/17/01 World Trade Center, NY Overview of wreckage at the World Trade Center. Andrea Booher/FEMA

The opening program of our series will focus on “Engineers’ Stories,” which is an aspect of the history of 9/11 and its aftermath that has not been well documented. Engineers played a critical part in the efforts of first responders in the hours and days after the collapse of the Twin Towers into the apocalyptic scene of Ground Zero. Assessing the danger or relative safety of debris on the Pile and the stability of damaged structures surrounding the site was the job of engineers on whose judgments the lives of rescue workers depended.

This program brings together engineers who devoted months or years to the recovery and rebuilding work to remember and reflect on their experiences. The panel will be moderated by Najib Abboud, a Managing Principal of Thornton Tomasetti, who led the team in the forensic analysis of the collapse of the towers.
