As-Built Documentation Checklist
As-Built Documentation Checklist
Quick Summary
An as-built documentation checklist helps subcontractors accurately record what was actually installed in the field. Keeping as-built information current reduces confusion during project closeout, future maintenance, and warranty work. This checklist is useful for project managers, foremen, crew leaders, and office staff responsible for maintaining project records.
When to Use This Checklist
- Throughout project construction as changes occur.
- When field conditions require modifications to original plans.
- After approved change orders are implemented.
- Before inspections and project turnover.
- When documenting underground or concealed work.
- During project closeout preparation.
- Before submitting final project records.
Before You Start
- Obtain the latest approved project drawings.
- Review all approved change orders and revisions.
- Identify work areas where field changes have occurred.
- Gather project photos and field notes.

- Assign responsibility for maintaining as-built records.
Safety Checks
- Verify documentation accurately reflects installed safety-related systems.
- Document final locations of underground utilities and services.
- Record relocated equipment, piping, conduit, or structural components.
- Verify concealed work has been documented before being covered.
- Confirm critical dimensions and clearances are recorded accurately.
- Ensure field notes are clear enough for future reference.
