A punch list is a list of items that do not yet meet the contract: damaged finishes, missing devices, incomplete trim, failed tests, labels not installed. It is typically created at or near substantial completion, when the architect and owner walk the building, and each item is assigned to the responsible trade with a due date.
Why it matters
Punch is the last thing between the contractor and retainage. Long punch lists delay final completion, keep crews tied up on a job that should be closed, and hold back cash. Owners can also back-charge for items a trade never finishes.
Worked example
Illustrative: on Riverside Medical Center, if the owner holds 10% retainage across the job, a long tail of punch items can keep a large share of that retainage unpaid for months. A clean punch walk (items photographed, located on the plan, assigned, closed with a photo) shortens that tail. For example, a fire damper access panel missing a label becomes one item assigned to the mechanical sub, closed with a photo.
Common mistakes
- Waiting until the end to start punch instead of running rolling, area-by-area punch.
- Vague items (“fix wall”) with no location or photo.
- Closing items without verification, then reopening them at the final walk.
How os.construction handles it
We’re building punch items as located, photo-backed records tied to the responsible commitment, so open punch can be seen next to the retainage it is holding up.
