Another Minn Bridge with problem gussets
Another Minn Bridge with problem gussets
(OP)
MN DOT finds some bent gussets in another similar bridge to the I35W bridge that collapsed. I guess we can say that the inspectors are a bit more focused after that collapse.

If you've ever worked with ironworkers things get bent all the time.

Speaking of the design documents, what is the typical requirement for saving and storing design docs after the structure is built? Aviation keeps these things forever because of maintenance requirements. What about non aviation structures?

Prost - I believe the industry standard is 7-10 years for keeping calculations and other documentation. This bridge and the 35 bridge are well over 40 yrs old. And as I understand it, the firm was acquired by another larger firm...when that happens there is a typical house cleaning. Hence I don't think it unusual to expect to find original calculations.
