What do I do when as-built change not marked?

📖 Verified core answer
Mark field changes while the work is still fresh. Redlines/as-builts are not a memory test at the end of the job.
🛠️ Field verification checklist
- Mark what changed from the drawing.
- Include room/grid/system and direction of change.
- Attach photo/sketch if allowed.
- Confirm whether foreman/PM wants formal RFI/as-built note.
- Do not leave unclear notes for closeout.
🗣️ Ask the foreman

🚫 Do not do this
Do not wait until turnover to guess what changed weeks ago.
Why this matters
The person doing closeout may not be the person who saw the field change happen.
