Vapour barrier, steel and formwork, checked in the last hours before any of it becomes concrete.
The vapour barrier is where slabs in this corridor go wrong: not extended beneath the whole slab, and punctures left unsealed. Neither can be corrected once the pour happens.
Annotated findings from Slab pre-pour inspections on Rockbank builds. Client addresses withheld.

Because the barrier only works as a continuous layer. An unsealed puncture is a direct path for ground moisture, and it is invisible the moment concrete covers it.
Additional reinforcement the engineering requires where a rib spans beyond the prescribed limit. Missing them changes how that rib carries load.
A day out is normally enough, but let us know the moment a pour date is set.
That sits between you and your builder to resolve. Most items here are an hour's work.

No. Concrete is final.
