Start with the decision, not the activity
A useful mockup is a controlled rehearsal of the finished work. It brings adjoining trades, actual substrates, lighting, tolerances, and inspection criteria into the same conversation.
The approved result should become a reference that crews can repeat and inspectors can measure. Photographs alone are not enough; the acceptance record must state what was tested and what remains conditional.
- Use production materials and the proposed installation method.
- Include interfaces between trades, not isolated finishes.
- Record acceptance criteria, comments, and the approved revision.
Turn intent into evidence
The best time to discover an impossible junction is while one square metre is being built—not after two floors are complete.
A sequence the team can use
- Choose risk, not convenience — Mock up the details with the highest interface or repetition risk.
- Inspect as a team — Bring design, construction, quality, and client approval into one review.
- Turn approval into a standard — Issue the accepted details and tolerances to every relevant crew.
Approval must be measurable
“Looks good” cannot govern hundreds of repeated details. Record tolerances, materials, finish, interfaces, and the exact approved revision.
