FL Bridge Collapse


Hard to imagine this happening with the current mindset on jobsites. Someone is going to be hit hard. No need to link, it's all over the news.

I noted one student (re: similar to the Florida school shooting survivors) saying: "Why do you continue to build over a road with vehicles on it?"

One eyewitness said a crane dropped a load where it buckled.

Re: FL Bridge Collapse


the Final product was to have cables to a tower at one end and another piece on the bedroom town side?

There is some concern the use of so much Titanium dioxide "pollution whitener" might have slowed/ lowered the rate of the concrete strength gain "enough to keep the bridge white for 100 years with out painting..."

On further review it is unlikely Ti- O2 weaken or slowed hydration...

Tree Huggers/LEED pimps Kill again? Maybe?

To soon to tell.

Love to hear from MEDEEK.

Will liberals try to out law driving under bridges now?

Will high school students skip another day of school to protest the deaths? More kids died travelling to various protests last week then from massacres......

I've been out of the LEED loop for a few years now that I'm retired (although still maintain the credential since it was hard to achieve) but I don't believe there has ever been a LEED bridge project. So take it easy on the LEED bashing. But I get where you're coming from with the lib's

Probably non-union contractor cutting corners. You know, the ones that claim they can do a job cheaper than a union contractor.
Makes as much sense as your liberal tree hugger comments.

Someone's nutz will be in a wringer, and they ain't mine. Some Engineer will be back to sweeping floors.

Sad about the deaths and injuries.

Re: FL Bridge Collapse


The bridge is just a part of parking ramp and other smaller projects rolled into one large Tax dollar eating burrito, Might of conflated "sustainability" silly Meme for the silly LEED Memes.... IM not so HO Spending $ to save dimes of energy is crazy dumb.

Building owners will cold chiseling the LEED Platinum Awards plaques off their building walls to raise their resale value 10 years from now.

I don't think anything in S. Florida is Union labor start to finish other then Medical care? or Lawyers?

This is a massive engineering boo-boo with an weak in concrete structural theory project manager that didn't know enough to say " hey, wait a minute, what takes the place of the suspension cables tension until they are installed?..."

I'm thinking you might not understand Florida too well. Unions here are a joke. Private companies are where all the talent is at in Florida.

Re: FL Bridge Collapse


So 6 dead so far, likely more since cars are still flattened underneath. If anyone asks you to bid on an accelerated bridge project, don't walk, run.

Re: FL Bridge Collapse


My heart goes out to families who lost the loved ones.

How sad, 6 people dead because of some engineering load miscalculation or faulty construction.I'm sure the finger pointing already started.

No, because the chances of non union labor is slim and none. More than likely someone who did the testing was paid off

Re: FL Bridge Collapse


I surely am no engineer ,but it looks like a poorly designed bridge to me. I can't even imagine the horror of being one of the people in the cars.

Re: FL Bridge Collapse


It was designed by the school,
More of the "everything works on paper" that we see all too much

Re: FL Bridge Collapse


I don't know if it has been done before but it was designed to be built at the side of the road and then swung into place.

No offense but there's a lot of stupid here in this post. A bridge collapsed and people are dead and you make it political?

And because more kids died traveling to protests (source please?) you think it's silly to protest against being shot at school?! False equivalency much?

Stick to construction. This is a tragedy. Somebody or lots of somebodies made some serious errors in calculation. Hard to believe something this big didn't have enough eyes on it to prevent it from happening.

Kind of similar to that building fire in the UK where all the pieces fell together after the fact.

Re: FL Bridge Collapse


Based on what I have read so far, it appears that the failure is due to:
Cost cutting
Avoiding inconvenience to traffic
Too much reliance on academic theory and calculations without regard to possible failure
Premature and poorly calculated installation prior to testing and inspection

That is just my best guess based on news reports and witness statements. And, of course, the fact that it fell apart.

Re: FL Bridge Collapse


My buddy has been a bridge inspector for many years, and just retired from that gig. He's a no-nonsense type, who basically said it's too early to tell what happened, but they'll be sure to get to the bottom of it (design and materials, etc.) so it's not repeated and lessons are learned.

I think there's more rigor involved, but stuff still happens in life. We'll see.
