Mock-up comments must translate into revised documents.
TIRREN · MOCK-UP CONTROL
Hotel mock-up room approval process.
A mock-up room is the last inexpensive place to discover a repeated design problem.
SHORT ANSWER
Do not release mass production until the mock-up record is closed.
Use the mock-up to verify dimensions, finishes, joints, interfaces, cleaning, access and installation. Record every change, revise drawings and samples, then obtain a clear production-release approval.
KEY PROJECT POINTS
What should drive the decision.
These are project inputs, not substitute engineering or automatic product approvals.
Physical samples should match production finish.
Interfaces with local trades need to be tested.
Maintenance staff input can reveal practical issues.
Photography alone is not a complete approval record.
Production should reference a frozen revision.
Pre-mock-up document freeze
Issue current drawings, finish schedule and product/sample references so everyone is reviewing the same baseline.
Inspect real interfaces
Check walls, plumbing, hardware, sealants, lighting and access around the supplied items rather than judging isolated products.
Close the snag list
Each issue should have an owner, corrective action and revised document/sample where needed.
Release production formally
Record the approved drawing revisions, finishes and accepted deviations before factory production begins.
PROJECT INPUTS
What to have ready before asking for the exact system.
A stronger brief shortens the gap between product interest and a useful technical/commercial response.

EVIDENCE BOUNDARY
A mock-up is an approval milestone, not a substitute for technical evidence.
Material/performance evidence still needs to be verified separately. The mock-up validates appearance, fit, interfaces and agreed project workmanship before repetition.
FAQ
Questions project teams usually need answered.
Who should approve the mock-up?
That depends on the project, but usually the client/design team and relevant consultants/trades should have a defined approval role.
Can production start while comments remain open?
It is risky. Open comments should be resolved or explicitly accepted before mass production release.
Should the mock-up be kept?
Where practical it can remain a useful workmanship/finish benchmark during rollout.
