Termite collars, vapour barrier, mesh and cover, checked in the last hours they exist as anything other than concrete.
The two findings that repeat on Melton South slabs are termite collars left off plumbing penetrations and the vapour barrier laid over the steel instead of under it. Both are invisible forever once the pour happens.

Annotated findings from Slab pre-pour inspections on Melton South builds. Client addresses withheld.

A day is usually enough, but tell us as soon as a pour date exists.
That question sits between you and your builder. Most findings take an hour.
