Duct Cleanliness at Closeout
QA/QC, Punchlist, Documentation & TurnoverVERIFYField judgment
Core Answer
Leave the system free of construction debris, standing water, loose liner, labels, screws, and temporary materials before startup and turnover.
What to Check First
- Inspect accessible interiors and openings
- Retrieve cookies, screws, and packaging
- Remove temporary caps only in the approved sequence
- Check liner and sealant debris
- Document cleaning and protected status
Ask Foreman
Before this system is released for startup, what cleanliness inspection and documentation does the project require?
Do Not Do This
Do not blow debris deeper into the system, leave cleaning rags inside, or remove protection before surrounding construction is ready.
Why This Matters
Debris damages equipment, contaminates occupied spaces, blocks devices, and creates immediate owner complaints.
Verify against: project cleanliness specification, startup/commissioning plan, owner requirements, foreman direction.
