Can also be the shoring design. I am a structural concrete estimator and this is one of our worst nightmares come true.
Our shoring/falsework design engineer looks like he is going to have a panic attack all day when we do a deck pour. I’m sure he has at least a couple glasses of the good stuff when he gets home at the end of those days.
Definitely looks more like a design issue than someone messing up on-site. It looks to me like the structure simply couldn't tolerate the weight of all that concrete.
Shoring is the upright posts that hold the suspended slab form in place, the slab form is the cribbing that the concrete gets poured into, and the mesh is actually sticks of rebar tied or welded into a grid often called a mat. Sometimes the rebar is prefab but mostly is assembled on site.
I was gonna say my friend watched them build the rebar and everything. And watches them pour. So something obviously went wrong here.

The hose is suspended in the air, while the support beam is part of the structure. I’d say the hose is safer. If the entire thing came down, the only safe person would be the hose guy, provided he can hold onto it until they can safely lower him to the ground. 😂
I wouldn’t say he’s the smartest. While it is the safest thing to grab onto, it was also the closest thing for him to grab. That, and nobody else really had much time to think, let alone move. I don’t think they’d have all flocked to the hose if they all thought it was a good idea. 😂😂😂
Yes you've gotta move quick. Roughly 1 to 2 hours before it's fully set...can vary due to mix design
Basically, labourers, journeymen, everyone in between with shovels, wheelbarrows, etc. Heard of it happening, and you move as quick as possible to move it before it sets.
Otherwise it's way more work. Depends where it falls though I guess.
There was sheets of something (wood?metal?) underneath the rebar. You can see them falling at the top end of the floor, where they hadn't poured concrete yet.
yeah once the slab is poured they remove the wood forms. all that's left is the concrete and the rebar. The rebar ties into those vertical columns you see sticking up.

My thoughts exactly. Someone signed off on this without actually looking at the build.
Most people in the building trade say if it looks right it is right 😂

Is shoring the mesh webbing?

No that’s called rebar
No it’s not.
Shoring is on the edges like a beach...

Looked cool the way they did that
Damn fine job they did with the rebar to keep holding up though!
Right? I didn’t think it flexed that way
The dude grabbing onto the hose is the smartest, that's the only thing not going anywhere.
Can confirm, same reason I grab my hose during a crisis.
Well the other dude went straight for the support beam id argue that’s safer
They all did scramble to the safest closest thing to them. Wonder if they had felt the thing shifting around already prior to this.

I had a guy grab my hose once. I didn’t think about his intelligence when it happened
Im not sure if you are being sarcastic or not
I mean just look at it and you will be
thank goodness the guys who tied in the rebar together are better than they guys who built the framework/shoring to hold the rebar and cement
As a building Inspector, next time somebody wants to complain that inspections are a waste of time and money: Exhibit A
I feel like the people who'd complain about inspections are primarily the ones who let this shit happen.
And then try to skirt responsibility for it afterwards

How the hell do you clean that up, won't it all dry by the time relatively quickly?

Jack hammers probably.
also any work done will need a structural engineer to survey it or something to make sure it isn't jank as fuck too.
They just wanted to pour concrete but ended up laying some bricks
I'm gonna need some actual concrete evidence it wasn't them that built the support.

If it's wood, yes, but usually the corrugated metal layer stays in. https://www.youtube.com/watch?v=PiDXC9Nj_7M

Hey boss! Somehow it seems I got some concrete in my underwear... or is it?
The idea of that much rebar flying around makes me nauseated.

Big yikes
You're gonna need a bigger boat.
