I saw on the Twitterer (must be true) this bridge was just recently moved, like over the weekend. Yikes.
Built off-site and installed a few days back I believe. Hard to tell what could have caused it from the video I've seen so far.
I don’t know about that but this clearly a case where we need to start outlawing bridges! The founders could have never envisioned a time when bridges would span 8 lane highways. Those bridges are a menace!!!
Probably wont be hard to determibe the cause. Bridge is new and I donr think even open to pedestrians. Engineers nightmare.
In guessing whatever pier or whatever it was sitting on in the middle failed. Either was not placed correctly or the pier shifted. When the walkway at charlotte motor speedway failed it was due to a halfass goyt job to secure the pier.
There was no middle support, dumbass. It was a single span.
Failure obviously initiated at left end where the green man lift is.
We will get a failure report in a few months and it will have recommendations and such. I remember when the Minneapolis bridge failed. Our company had done bridge inspections on it years before it failed. Corporate emails imploring all employees to direct any media contact to PR. Good times.I think this could be the failure point. If that column blew through the roof, then it would have lost all structural integrity.
What a nightmare. I bet you Engineers and Contractors are going through their plans and specs with a fine tooth comb now.
FIGG, the designer, has an impeccable reputation. My money is on either the construction contractor being at fault or a material defect. A lot of post-tensioning strands are failing when they shouldn’t be.
I read they had done a stress test on the bridge earlier today. If that is true....
The post-tensioning strands failing are material defects - manufacturing. The steel has a high carbon content and behaves more brittle than ductile.
I would have to read a lot more on that. They should know the properties of the materials specified for the job. If something other than specified is delivered it would be up to the engineers and contractors to identify and rectify the issue before installation.
Just read that a FIGG employee, I would suppose an engineer, left a voicemail to a FDOT employee suggesting there were cracks in the structure and that obviously something would need to be done to repair them.
Thats gonna be an expensive phone call.
I wonder how much stress is put on the structure when it is picked up and moved. It would have to be pretty fragile.
