There seem to be a distinct lack of rebar in the bit that's fallen off.
That can't be right surely?

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.

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.
