QA/QC, Punchlist, Documentation & TurnoverQA/QC starter — verify before calling it complete
Labeling should help the next person know system, area, direction, or status without guessing.
Field checklist
- Use the job’s approved label/marking method.
- Mark system/area/status where useful.
- Keep labels readable after insulation/ceiling if required.
- Remove confusing temporary marks when directed.
- Ask what must remain for turnover/TAB/service.
Ask foreman
What needs to be labeled or marked before this area is considered complete?
Do not
Do not leave unclear marks that make the next crew guess.
Why it matters
Bad labels create wrong tie-ins, missed TAB work, service confusion, and ugly turnover.
