Barrier, steel and set out, in the last hours before any of it becomes concrete.
Box Hill sits on Wianamatta Group shale, and the clay weathered from it is reactive with an appreciable shrink and swell range. That is what your slab is designed around, and the pre-pour inspection is the only chance to confirm the thing that was designed is the thing being built. Everything on the list below is permanently invisible within hours of the truck arriving.

Because the slab has to stay stiff enough that seasonal ground movement does not crack the house on top of it. That produces deeper beams and more steel than a stable site would need, which is precisely why it is worth confirming the steel is where the engineer put it.
You can inspect the finished surface, but not what is inside or beneath it. Every item above stops being verifiable the moment the concrete goes down.
About an hour to ninety minutes on a standard lot, and the report usually reaches you the same evening so the builder can act before the pour.
We move with it and there is no charge for rescheduling. Dates shifting is normal and it is never a reason to skip the stage.
We record penetration positions where they are visible, because a point in the wrong place costs very little to move now and a great deal once the slab is down.
The engineering for your lot and the soil report it was based on. Together they tell us what the slab was designed to do.
