Stage Inspections vs PCI Only — Is It Worth Inspecting at Every Stage?

The Case for PCI Only

If you can only afford one inspection — or if your builder's timeline is moving faster than you can organise stage inspections — the PCI is the one to book. It catches the most defects at the point of maximum leverage. Your builder still has skin in the game at PCI — you haven't settled yet.

For a straightforward single-storey volume build in a well-serviced corridor by an experienced builder, a PCI-only approach is a reasonable minimum.

The Stages Where an Inspection Delivers the Most Value

Not all stage inspections are equal. The value of an inspection at each stage depends on what can still be fixed at that point.

Pre-pour slab — highest value after PCI. This is the only opportunity to assess reinforcement placement, termite management system continuity, and slab edge dimensions. Once concrete is poured, these elements are permanent. A defect found here costs nothing to fix. The same defect found at PCI — or discovered after settlement — is expensive or impossible to rectify.

Frame — second highest value. The last opportunity to assess structural bracing, tiedown connections, and timber sizing. Once plasterboard is installed, these are invisible. A missing brace found at frame stage is a straightforward correction. The same issue found after plasterboard requires cutting into the wall.

Waterproofing — high value if wet area compliance is a concern. The last opportunity to assess membrane height and junction quality before tiles permanently conceal the waterproofing. If your builder is using a waterproofing contractor with a history of non-compliance — which VG Inspect can advise based on our inspection history — this inspection is worth booking.

Lock-up and pre-paint — moderate value. These stages allow assessment of window and door installation, roof completion, and external cladding. Most items found here can also be found at PCI — but catching them earlier gives more time for rectification.

The Recommended Approach

For most buyers in SEQ, the optimal approach is: pre-pour slab inspection + frame inspection + PCI. Three inspections at the three points where what we find is either impossible or very expensive to fix after the fact.

If budget is limited: pre-pour + PCI. The slab is irreversible. The PCI is your last leverage point.

If budget allows a full program: all stages. Complete coverage, maximum leverage at every point, and a documented construction history that supports any future warranty claim.
