Nottingham car park COLLAPSES with vehicles left dangling 50ft off edge:

Looks like some kind of edge cantilever-spandrel assembly didn't have adequate rebar development into the main slab.

Okay, didn't see the second link, so I missed the extra "floor" below the pics shown in the first link. I'd estimate around 30', too.

If you look really closely there's evidence there that the joint between the car park and the cantilver has been repaired. The screed under the laguna ( the black car) looks quite new compared to the section around the column.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

I thought the same. Plus the way it cleaved away smoothly, suggesting a topping mix with small pea gravel aggregate, compared to the coarse break of full sized aggregate used during the original concreting around the columns & elsewhere. Efflorescence suggests there may have been a full depth cracks for some time. Make me wonder if the cantilevered section was a historic low spot and bird baths pooled along the wall when it rained.

With the cantilever "removed" - the frame looks like the first level. In order to keep the formwork and shoring of the main parking deck the same, maybe there was a cold joint at the cantilever.

Makes one wonder what kind of repair work was going on. Hopefully not urethane injection. The scaffolding may be what's holding up the rest of the cantilevered section. I was surprised how little damage it sustained when the section of concrete came to rest against it but it is jacked in place against the cantilevered concrete. Link
