Cover, steel and formwork, in the last hours before any of it becomes concrete.
This is the stage Austral is best documented for in our library, and the findings make the argument on their own. Cover to reinforcement short of the minimum, more than once. Edge and middle beam steel not as detailed. Mesh sitting in contact with pipework. Waffle pods needing cleaning out. Formwork incomplete. A shower recess never formed, which becomes a jackhammer job the week after the pour. Everything on that list takes minutes to fix the day before and is permanent the day after.

Cover is the concrete between the steel and the outside world. Too little and moisture reaches the reinforcement, which corrodes and expands and cracks the slab from the inside. It is measured in millimetres and it is not recoverable after the pour.
At that point the steel has no cover at all on one side, and you have two materials that move differently locked against each other. Both are reasons the detail keeps them apart.
It is formed in the slab. If the set down is not there before the pour, creating it afterwards means cutting into a finished structural slab, which is exactly the sort of remedy nobody wants to be negotiating.
You can look at the surface, not at what is inside it. Every finding above stops being verifiable the moment the truck leaves.
We move with it, at no charge. Dates moving is normal on these lots and it is never a reason to skip the stage.
An hour to ninety minutes on a standard lot, with the report generally out the same evening so the builder can act before the pour.
