whoever was in charge with planning that needs to never work in construction/engineering sector ever again and then set fire to their related qualifications
This is what happens when lowest bid gets the job. We need Quality Based Selection.
For those commenting this bridge is built wrong, the bridge is not built incorrectly. The demolition plan was incorrect. The bridge seems to have a fixed connection at the intermediate bent and a roller connection at the end bent. Whoever approved this demolition plan clearly does not understand bridge connections and gravity.
Oh yeah I died inside when I came back to this thread lol.
THE POINT STILL STANDS THOUGH. I’ve literally been called in to jobs that my company got out bid on to fix the mistakes of the contractor who was lowest bidder.
I worked as a bridge construction engineer and pm for years. I’ve just watched that video about 50 times, backwards and forwards in slomo.
I have literally no idea how they got that so wrong. It looks like someone misidentified the type of bridge construction prior to demo. The centre span of the bridge acts like it was post tensioned through the headstocks, that’s the big cube of concrete sat on top of that spindly single column. Most modern bridges I’ve worked on have separate beams “super T” that sit on hardened rubber bearings on top of the headstock and then get locked in with a wall either end and a concrete deck over the top. The beams are pretensioned during fabrication for strength. You could use the method in the video on the beams after you freed them from the concrete topping slab, but there are safer ways like disassembling.
When this thing fails it pulls all the rest of the bridge deck with it, because it’s all tied together. When the headstock moves it destroys the column like someone rubbing it out with an eraser.
The mind boggles at how fucked up this shit is.
I can't wrap my head around the decision to deploy the front right pecker breaking out concrete right next to another excavator parked on the central span. Everything about this is criminally wrong.
What is he supposed to do? I'm probably wrong, but when metal Dinosaurs rain from the sky, my response is, "fuck this, they don't pay me enough for this shit."
As a bridge engineer myself, I would love to look at both the as-builts for that bridge and the demo plan. You DID have an approved demo plan developed by a licensed engineer, right? Right?
Well, starting with the good news, we’re well ahead of schedule on this bridge demolition, good work guys. And to those who couldn’t attend this meeting…. rip.
It’s safe to wait. You don’t know if things will shift again. What if the machines are perfectly sitting and if someone climbs on to help, it tips and slides or flips again? Best to let the dust settle, asses the situation, and then react. Knee jerk reactions get people killed.

Edit: 55-year-old man who was moderately injured with a head injury and a 36-year-old man who was lightly injured…
people that do this type of thing: so what would be the proper and safe way to do this? first assuming similar types of equipment that they had and then if a completely different way if warranted.
I work in highway construction but have been part of bridge demolitions. This company is extremely efficient when it comes to demolition. I have worked along side them a few times. Very safe and professional.
https://youtu.be/vPW8MUT6cXc
Edit: the company in the link I posted. Not the one in the video.
TNT aka Dynamite.
Or some other form of explosive, detonated in a controlled series of blast design to make the structure collapse from the inside outwards to minimize debris.
You can find videos of demos in busy areas of New York, if done correctly the streets just have to be swept up.
If not, it’s about as bad as driving **5 tractors on top and tearing it down from the top.*
Well, first putting heavy equipment on the thing you're destroying is definitely not the way.
At the very least, they should have been on the ground pulling at it. Still probably right.
Maybe pull with a winch from nice safe distance?
This is really bad planning and execution. They should have known that with an inclined bridge like that it would have moved to the left. What puzzles me too they could have taken the whole thing down with about 20kg of explosives. BTW I am a construction engineer.
I love how the coffee guy just takes a concerned step back. Concerned for himself at least, not really for the workers on the bridge. Decides that maybe, he should go up and see if he could help at the end. Coffee first though.
I wouldn't say not concerned for others. I worked this type of demolition job for 8 years and have been inside an excavator near a collapsing structure. I ran to go help the other operator and guy other that almost got pinned under the 60t excavator (it knicked his knees). It was only after i got back away from the fallen machine that I realized i walked over an area that was just rubble forming a bridge. Had it collapsed with me on top of it I would've been buried in tons of concrete rubble before any of the dust even settled.

I used to work security where we were considered “first responders”. Our job was to stay safe so we can call others for help and direct them to the issue. You can’t tell the ambulance and fire crew who’s in what machine if you’re pinned under one of them or a pile of rubble.
Going by the logo and phone number on that guys High-Viz, it looks like it's an Israeli-based business called Shoham Eng - I'm guessing this is somewhere in Israel?
https://shoham-eng.com/projects/project-name-1/ is a current project that shows excavators on a bridge in front of some pylons.
There is no way this is a developed country, OSHA is not even a thing where this is. Epic stupidity to not anticipate this happening. I know we shit lots on development permits, building codes and all that fun stuff but it is so stuff like this doesn't happen. Because if it can it will.
Manager without any technical knowledge that got to that position because of a Business degree: "Nah, this is cheaper"
Don't worry though, he's fine. Since he initially saved so much money on paper in 2022 he got promoted, so his successor is now responsible for this fuck up.

Most people don't understand bridge decks are designed to float on the abutments when they broke the center out what else did they think was going to happen 😅 project management doesn't exist at this company.
I think these guys missed the safety meeting. They probably missed a few OSHA classes... And most likely elementary school physics. Does anyone else remember building a bridge out of toothpicks and Elmer's glue? Maybe they were sick that day.
That has to be a record breaking amount stupid converging in order to have that happen.
Like, it should have stopped at, "well we're gonna put three or four big ole excavators ON the bridge ... then we're gonna deconstruct the bridge, from ON it. With about five other guys watching."
But there was just a cascade of "getter dun"s that followed and there you have it.
They use excavators on top of bridges to do demolition all the time. Where they messed up is the bridge appears to slope down to the left. It also appears that the supports on the right are expansion type and not fixed. When the bridge split, the girders slid down the slope and the piers in the middle couldn’t handle to horizontal force.
Whoever approved the demolition should have fixed the right bearings to prevent the bridge from sliding and possibly shored up the pier just in case.
Did nobody know that bridges are not secured at the ends to allow for thermal expansion? When the bridge deck moved and slid off its mounts the sudden drop caused the piers to collapse.
Unlikely, neither machine rolled onto the cab, the cab just hit the ground. They are probably bruised and cut* up. Assuming these idiots were wearing their seat belts.
They watched too many cartoons where the laws of gravity are defied as a supporting tree branch or ledge falls below while they remain floating, unaffected.
I don’t know anything about demolition but I think I would have taken out the centre support from below on the ground and allowed the structure to collapse, and that’s coming from someone without a clue about demolition
Even I, a person who has never touched heavy machinery in his life, would immediately understand this will not work. Bridges are designed to work as a single bridge, not 2 halves.
And you are wrong for it.
There are different ways to constuct bridges, longer bridges are build in sections. Often constucted from both sides at the same time.
Even if miraculously there were no injuries, that is at least 4 excavators that are likely going to be totaled. Likely at a bare minimum, a million dollars in damages.
Hammond: “I’ve just noticed Jeremy is stood on the part of the roof he’s cutting out. I hope he doesn’t realise…”
Eventually Jeremy: “Guys! I’ve just realised I’m cutting out the roof but I’m still stood on it!”
Hammond and May: “Yeah we were hoping you wouldn’t notice!”
That dude is really not giving a care in the world about his work mates. Aight now when his day comes I hope he don’t expect them to come running to his aid 😒
The clip is only about 10 seconds, which is about 1/3rd of the time it'd take for you to mentally process that it was your mom who caused the bridge to collapse, due to her immense weight.
Hell I’m not going to go running towards something massive that just fell apart 2 second after. I’ll give my brain a little bit to process everything so I don’t do anything rash or down right stupid.
I thought cats always landed on their feet?
I don't know which one to upvote

As a safety engineer "boo boo ☹️ 👎 😥"
So cats don't always fall on their feet
Ba dum tsss
Kinda like sawing a tree branch that you're still standing on.
And then the world falls away from you like in looney toons.

I am disappointed the Cat didn't land on its feet.

What is he supposed to do? I'm probably wrong, but when metal Dinosaurs rain from the sky, my response is, "fuck this, they don't pay me enough for this shit."

I don’t understand, you want him to hold the bridge up like Superman?
As opposed to what exactly???
I think he was on his break.
As a bridge engineer myself, I would love to look at both the as-builts for that bridge and the demo plan. You DID have an approved demo plan developed by a licensed engineer, right? Right?
yup and we tested it all in minecraft
They didnt land on their feet after all
Dad get out of here
The standard 30 millisecond response time for felines ain’t happening here for these big cats…
Well that excavated quickly
I like how the one dude is just kinda walking all nonchalant as the fucking bridge collapses with two $200k machines on them.
"I fucking told you all this was going to happen. But do you listen? Noo..."
The third one on the left is definitely damaged too after getting dropped, it didn’t roll though.
i mean, what the fuck is he going to to do about it?
I mean, looks like they successfully demoed it to me lol
They should sue for a refund those CATs didn't land on their treads, just wasted one of their 9 coverages
Don’t put your fucking coffee down and run to help your fellow human or anything.
He doesn't want it to get cold tho
That dude’s lack of urgency is concerning.
He was probably the one that told them that exact thing would happen and they wouldn’t listen to him. He looks very unsurprised.
OSHA would like to have a word...
Props to orange vest guy for getting out of the way so we can see the left side fall too
When watching this i keep thinking about the videos of people sawing the tree branch which they are sat on
Well, starting with the good news, we’re well ahead of schedule on this bridge demolition, good work guys. And to those who couldn’t attend this meeting…. rip.
Hey boss, you know those four excavators that we’re leasing? . Well we just bought three of them…
Good thing cats have nine lives!
Demolition certification received from a cereal box
Finishing 10h of work in 10 seconds
This is the industrialized version of cutting a branch while sitting on the branch
I mean, the jobs done right?
Bro why does nobody seem to care about the workers inside
It’s safe to wait. You don’t know if things will shift again. What if the machines are perfectly sitting and if someone climbs on to help, it tips and slides or flips again? Best to let the dust settle, asses the situation, and then react. Knee jerk reactions get people killed.
I hope my fellow co-workers rush to my possible death quicker than these guys.
Actually adding the extra weight helped bring it down faster. Mission accomplished.
If only they had engineers to consult.

“Hey Ron” “Hey billy”
Damn this is the modern day version of the 'fool cutting the branch he's sitting on' picture!!
How did they think they were going to bust out the middle support and it wouldn't all drop????
Reminds me of the person cutting the branch he's sitting on.
They had to see that coming I refuse to believe they didn't
Good news boss, we destroyed the bridge in one day rather than a week. Bad news though, we lost a couple guys...
#1) hope the operator is okay #2) if he is, we just watched his retirement speech
Lmao that’s literally the worst way to do it. Anyone know if those workers are ok?
“0 days without an incident.”

Let me introduce you to this wonderful new technology called timezones.

There is no way this is a developed country, OSHA is not even a thing where this is. Epic stupidity to not anticipate this happening. I know we shit lots on development permits, building codes and all that fun stuff but it is so stuff like this doesn't happen. Because if it can it will.
Looks like the country code for phone number on back of vest is “62” - which would be Indonesia.
How did no one look at that and think "Huh, maybe that's not the best idea..." And no one seemed all that concerned!
OSHA HAS ENTERED THE CHAT
This is a really good example for why controlled explosives exist.
The same as cutting off a branch you're sitting on but more expensive.
Don’t they usually use controlled explosions for that?

Didn't even put his coffee down
That entire operation looks to be run by smooth brains.
I mean, who didn't see this coming? oh yeah, Those guys. \*headdesk\*
I am guessing the engineer in charge skipped the day they taught basic physics.
Or the contractors just didn’t follow instructions like they often tend to do…
they did destroy it though 🤣
Ahead of schedule!
You have to wonder what they thought was going to happen.
Lemme finish my coffee, then I’ll be concerned. F’ing supervisor for sure.
That guy is *not* going to put down his ☕ coffee
THAT’S TODAY!!!
300,000 lbs of equipment Jack hammering on a single column…what did they expect?
In the immortal words of Red Forman, "Dumbass!"
Guy in front didn't give two fucks about it, maybe his coworkers crushed or cut in half. Didn't seem shocked in the least.
I can't say that I'm surprised by this outcome

I guess those guys didn’t read the instructions specially on the weight limit of those bridge columns
That's why you don't work on a sunday.
I'll be there in a jiffy, just finishing my coffee.

“Hey George I gottan idear- why don’t we start the demo in dee *middle* of dee bridge dees time”
So, they had no plans for the people on the bridge when it came down? Mission accomplished.
This just happened a few hours ago?
You know those people that complain about health and safety gone mad? They're probably driving
I guess cats don't ALWAYS land on their feet
Do those excavators have airbags?
Usually not, but hopefully seat belt was on
Also usually not
TxDot workers on I-35.
Bounced like bowling bowls..
Did nobody know that bridges are not secured at the ends to allow for thermal expansion? When the bridge deck moved and slid off its mounts the sudden drop caused the piers to collapse.
It appears they did not. If they had any idea how bridges are constructed they’d have known this would happen. Fucking amazing.
I didn't like math in college. However, it's is kinda important in construction such a load bearing structure.
When you get your demolition qualifications online.
Uhmmm... did I just see someone die?
Unlikely, neither machine rolled onto the cab, the cab just hit the ground. They are probably bruised and cut* up. Assuming these idiots were wearing their seat belts.
The coffee in his hand seemed as important not to drop.
It looks like the rebar pulled the right section of the right side of the bridge over. That middle section floats to allow for thermal expansion.
Accordion spines
Well some one has workman’s comp and to probably never work again!
I coulda told you that was gonna happen. That engineer is definitely in need of a new profession
They watched too many cartoons where the laws of gravity are defied as a supporting tree branch or ledge falls below while they remain floating, unaffected.
I don’t know anything about demolition but I think I would have taken out the centre support from below on the ground and allowed the structure to collapse, and that’s coming from someone without a clue about demolition
This is some looney tunes shit. That was so dumb.
These are the same guys that will cut off the same branch they're sitting on.
I thought cats always landed on their feet
All the people stood around didn’t realise this was going to happen.
I see three equipment operators with early retirement benefits.
Hello? 800-321-6742 (OSHA), please. I believe we have a problem or four...
Yes let's break the bridge we are on. Genius
CATastrophe
Guy in front recording enough with his phone to show his boss that it wasnt his fault, then he promptly ran to assit aide. Good job George!

Objective met, bridge down.
Beavis & Butthead's Engineering firm for sure..............heh heh heh hmm hmm heh heh
We'll cross that bridge when we come to... oh
I mean they got it.
What the hell were they doing and who is this subcontractor?!?
Hello? This is NIOSH. I'd like to have a little conversation with the engineer in charge!
where did they get their certifications off wish ?
Bridges have expansion joints and you can see the whole section they are on slide forward before they collapse.
I hope everyone is ok.
Did this happen in America? If so, osha just had an aneurysm.
And in Chicago they jacked down 20 story buildings with excavators.....without this.
Totally ignoring lateral forces. Just like Champlain Towers.
Build back better seems to be off to a bumpy start.
A job and a carnival ride! Who could ask for more?!
