What this means
Preserve the evidence while important interfaces are still visible and correction remains practical.
A concealed-work checkpoint is planned from the approved scope and construction sequence before work begins. It records the relevant materials, routes, junctions, tests and unresolved points before ceilings, walls, floors or finishes make them inaccessible.
Practical sequence
Eight controls before concealed work is closed
The checkpoint plan should match consequence, repair difficulty and the evidence required after handover.
02
Confirm approvals
Check applicable authority, management, professional and competent-person requirements before treating work as authorised.
03
Set hold points in writing
State the location, notice period, required evidence and person authorised to release the next stage.
04
Verify materials first
Record product identity, model, batch, approved substitution, warranty and intended location where relevant.
05
Capture overview and detail
Photograph room orientation, routes, junctions and close details with dates and useful location labels.
06
Complete required tests
Arrange the authorised water, electrical, pressure, waterproofing, drainage or other applicable test before closure.
07
Keep unresolved work open
Assign repair, evidence and reinspection requirements before allowing incomplete or untested work to be covered.
08
Preserve the final pack
Store drawings, marked-up routes, photographs, tests, approvals, variations and release notes for future decisions.
How it works
From approved design to a controlled release
Map
Identify concealed elements and their required evidence before work starts.
Notify
Use written hold points so the right reviewer sees the work at the right stage.
Verify
Record visible condition, materials, tests, approvals and unresolved points.
Release
Allow closure only through the agreed authority and preserve the final concealed-work record.

Get Instant QuoteWhich renovation stages should be inspected before closing?
It depends on the approved design and work sequence. Common checkpoints involve services, supports, waterproofing, substrates, interfaces and required tests.
Are progress photographs enough?
No. They preserve visible context but do not replace the applicable test, approval, certification or competent-person decision.
Can DPM approve structural or regulated service work?
No. These decisions require the appropriate appointed professional or competent party.
What if work is closed before inspection?
Record the evidence gap. The next action may involve documents, specialist review or authorised opening-up work, depending on consequence and contract.
Should every concealed item have the same checkpoint?
No. Prioritise according to consequence, approved scope, required test, repair difficulty and the evidence needed after handover.
