By that point the concrete had been down for weeks and nothing could be done about what sat beneath it. That is the argument for the pre-pour inspection in one image: the barrier is either continuous on the day, or it is a permanent unknown.

Because the barrier only works as one continuous layer. A missing section is a direct path for ground moisture into the slab, and the cost of fixing it before the pour is a few metres of plastic and some tape.
You can inspect the finished slab surface, but not what is inside or beneath it. Everything listed above stops being verifiable the moment the concrete is placed, which is why this inspection has such a narrow window.
We have not yet attended a pre-pour inspection in Craigieburn that produced published findings, and we will not relabel a frame photograph to fill the gap.
Roughly an hour to ninety minutes on a standard lot, with the report usually issued the same evening so the builder can act before the pour.
We move with it and there is no rescheduling charge. Dates shifting is normal and it is not a reason to skip the stage.
We record waste and sewer point positions where they are visible, because a point in the wrong place costs very little to move now and a great deal after the slab is down.
