forensic engineer that showed up to figure out what happened and tell them that they had to retrofit the remaining structure or the rest of it would also collapse.
The steel fabricator was to blame and we had a nice evening of arguing between me, the fabricator and the architect. I won and they ended up retrofitting the north end zones with a great Spanish arch design courtesy of yours truly.
The architect, HKS, and the steel fabricator were lucky that the north end zone collapsed before the football season. Several months later and several thousand people would have been crushed.
