Several PPL Dead At FIU Bridge Collapse

Again, examine picture I posted right after collapse.

You will note no first responders or rescue trucks.

Furthermore, normal vehicles there, not fire trucks and you can see 1 car turning around to get out.

My mistake all the pictures and video I've seen doesn't show that crane....that contractor is in a lot of hot water for doing something like that without completely closing the road down.

See post above.

That’s why it is imperative to examine the evidence and connect dots.

Even Tony Beets wouldn't try that

It was 950 tons. Hindsight is 20/20 of course, but it just seems odd to someone uninformed like me to think of it being stress tested before it was finished with traffic under it, which I think is different than routine repairs on bridges that are already operating. I can understand it getting finishing touches while traffic was under it (after being deemed structurally secure), but stress testing it before it is open seems like something to do at 2 am Monday when it is easier to close the road to traffic.

The whole grand idea was that the bridge was built alongside, to avoid road closure, and then it was rolled into place. Florida fast-track construction or something along those lines.

Again, my experience is based almost solely on what Tony tries to lift, and the "Big" crane he brought in had a load limit of 50 tons. That pictured crane didn't look 20 times bigger than anything Tony uses.

If temporary cable failed (on above Golden Gate Bridge Question) same thing would happen. Ditto GW Bridge.

Impossible to eliminate all possible risks. Risks can only be minimized, but even then, not eliminated.

Life is inherently dangerous.

Cranes are rated approximately. Remember the pulley experiments from Junior High.

You cannot judge a crane simply looking at it in a low res picture.

Has to do with pulleys and support arm structure.

One can see the massive arm structure containing multiple pulleys in photo above. That’s far different than a Tony Beets crane that needed to be transported by river in the Yukon.

Furthermore, the crane was not supporting 950 tons. The side supports were doing most of that.

You just need to remember next to last episode where his crane could not support full weight of bucket chain, so he used a platoon to take weight off crane.

Construction in place would have meant danger to workers and drivers, along with road closures for a year +

Original crane with boom lowered after collapse. Note writing on boom.

Compare that to writing on booms brought in after collapse.

Original crane could not be used. Cable failure.

There was a whole section of the bridge that wasnt put up and i dont understand why. Literally should have been the first piece to go erect as it is what Distributes and holds the weight of the entire bridge.

See picture attachment below.

Looks to me like it was a construction error and not an engineering error.

That’s why the crane was temporarily in place.

One cannot build and anchor that piece on side of road and move into place.

Crane was being used until that could be put in place, which was why stress tests were underway.

Also reason why not open to public.

Bridge was still under construction.

Also note, the ENTIRE Bridge was 174 ft long and 950 Tons.

The part that collapsed was probably 60% of that.

Another piece was needed to go over water/drainage.

Dreadful, inexcusable nonsense. Criminal charges should be filed against all involved if proper, and the families of the deceased should own the companies involved.

Pure speculation, but it appears that side of crane boom has a phone number. IE, rental crane.

Crane owner appears to have gotten it the hell out of there quickly after accident, as noted in earlier posts and by large area where it once was on the side of road.

It appears to be the result of a stress test that involved loosening the steel cables. Why not do this while closing the road to traffic first?

[IK6SPEED]

You can see crane and everything in this video.

Only a portion of bridge up.

So looking into this more, the crane that is in question was in the far right lane where the Technical Rescue truck is parked in the later pictures. They had 2 of the 3 lanes coned off so they could perform the work. Looks like it was George's Crane Service out of Miami. It's odd that in the 100 pictures or so along with all the video that crane is nowhere to be seen later. You would think that they would have not let the crane leave after the incident.

It was off to side.

Rental Crane owner got it the hell out of there.

Ask yourself why, especially as other cranes were brought in to attempt rescue.

Crane was parked in the far right lane where the white rescue truck is parked in your first picture. Your second picture proves that....look where the crane is in relationship the boom lift and the crash wall. Not trying to argue but your own pictures prove what I'm saying.

[UncleWede]

NTSB/OSHA didn't immediately impound the crane?

Crane is in right lane

Good question but it disappeared pretty quick.

It was gone long before they arrived.

That is what I said I believe. Side of road. It’s why I posted pic.
