What Is a Punch List in Construction?

Key takeaways

A punch list is the list of small items still to be completed or corrected when the work is substantially complete: usable, but not finished.
The contractor usually prepares it and the architect or owner adds to it on their inspection; each sub fixes its own items.
Final completion, and usually final payment, waits until every item on the list is closed.

A punch list is the list of work still to be completed or corrected once a project, or a part of it, is substantially complete. Typical items are paint touch-ups, a missing cover plate, a door that does not latch. The contractor prepares it, the architect or owner adds to it, and final completion waits for every item to close.

What goes on a punch list

Items that do not stop the owner from using the space but are not yet as the contract documents require: finishes damaged or incomplete, devices missing or not working, hardware out of adjustment, cleaning. Each item names one problem, where it is, who fixes it and when. Work that would stop the owner using the building is not a punch item; it means the work is not yet substantially complete.

On AIA-based contracts the list travels with the certificate of substantial completion: the AIA's summary of G704 says the contractor prepares the list of items to be completed or corrected and the architect verifies and amends it. Public owners do the same; Alaska DOT&PF's construction manual has project staff prepare "a comprehensive list of items the contractor must complete" as the work nears substantial completion, then revise it after the final inspection.

An example punch item

On a fictional office fit-out, one line reads: "Room 212, east wall, outlet at the desk has no cover plate. Fictional Halvorsen Electric. Due Friday. Status: open." The electrician installs the plate and marks it fixed with a photo; the superintendent looks at it and closes the item. If it is still wrong, it goes back to open with the reason.

Punch list vs. deficiency list vs. warranty item

Some owners call the same list a deficiency list; the idea is the same. A warranty item is different: it is a defect found after the owner has accepted the work, and it is claimed against the warranty, not added to the punch list.

How it works in Conflo

In Conflo's punch list the GC logs each item with its location, the responsible company, a priority, a due date and an optional photo. Each sub sees only its own company's items and marks them fixed with a photo or a note; only the GC closes an item or sends it back.

The bottom line

A punch list is the short list between substantial completion and final completion. Keep it specific, one problem per item, and close nothing you have not checked.

The shorter your own list is before the owner's walk, the faster you reach final payment.

Questions

Who makes the punch list?

Usually the general contractor, from its own walks before substantial completion. On AIA-based contracts the architect then verifies and adds to it. Check your contract, which may assign it differently.

When does the punch list start?

Before substantial completion. A GC punches each area as soon as its finishes are in, while the trades are still on site, so the owner's and architect's walk confirms a short list instead of writing a long one.

Does a punch list hold up payment?

Often. Many contracts release most retainage at substantial completion but hold back an amount for the open items, and final payment waits until the list is closed. Your contract sets the terms.
