That's what I thought too. It goes a long way to explaining why that bit
fell off. It will be interesting to see whether they can effectively
check the rest of it for structural integrity. My guess is that they
will have to demolish the whole lot. More than one multi-storey car park
in Norwich has gone the same way (due to deterioration of the concrete
rather than lack of rebar). Even one of the replacements had structural
issues a few years later.
Most of them have suffered from lack of maintenance generally and water gets
in the cracks etc, and metal inside rusts. I'm expecting several around
here to be condemned soon. Bloody eyesores they are.
This newsgroup posting comes to you directly from...
In the picture a transit van has reversed into a wall and knocked it off
the deck of the car park.
The question is does the wall have to stop a transit van going through
it or not?
The car park shows no signs of falling down.
It looks to me as if there is a cantelevered section of floor, beyond
the main floor, with a wall on the far edge of the cantelevered
section. It seems the cantelevered section has collapsed under the
extra weight of the van, taking the wall along with it.
Actually, looking at that silver people carrier, I suspect it rammed
into the wall in reverse which is which why its wheels are hanging
over the edge. That retaining wall has an L shaped bottom which
looks like it was attached to the precast flooring sections with
rebar. where the man is attacking with a breaker is the top surface
so you wouldn't expect to see any rebar there.
Whatever weakness had built up in the structure because of concrete
'cancer' was exposed by the sudden impact.
Ah, now it becomes a bit clearer why there are vehicles with their rear
wheels hanging (or else almost hanging) off the floor. I'd thought that the
wall was flush with the vertical pillars and horizontal beams on that floor,
and that therefore the collapse had also made vehicles roll backwards. But
looking at the floor above, it extends another metre or so, so part of the
floor has snapped off, back to the level of the horizontal beam.
The silver Transit-type van doesn't appear to have any damage to its rear
end, which you'd expect if it had hit the wall hard enough to snap it off.
Looking at other news photos it looks like the car park was already
under renovation and that would be the most likely cause of the collapse.

Looking at those, my first thought is that the deck overhang past the
horizontal support is rather large for such a thin deck, especially with
the weight of the vertical fluted fascia panel perched on the end.
Also noticeable that the rear wheels of the silver people carrier are
actually past the horizontal support - compare with other parked cars
whose rear wheels are more or less sitting on the horizontal beam
underneath (see image 23).

Although the people-carrier is nearer the edge, I don't think its bumper
would have hit the parapet. Perhaps they should have roped off that line
of parking bays while they fettled around underneath.
The line of overhanging deck/parapet could have peeled away starting at
the scaffolding near the blue saloon, and running towards the entry/exit
ramps, before being halted by the pit-props.
The Armco at the side of the ramps is still there.
Look again at picture 26 along with picture 24. The Armco is still
attached to and is dangling from the end of the parking bay at the RHS
(above the crushed scaffolding). The rest of it landed on the lower
level ramp to the private car park underneath the NCP car park.
A look around street view
gives a better look and feel of the layout than the photos in the newslink.
