Before installation
Shop drawings should show device locations, routes, elevations, cabinet connections, interfaces and references to approved equipment.
During construction
Changes need marked-up records while routes remain visible. Waiting until handover turns the as-built set into guesswork.
At handover
Drawings should match labels, test results, asset lists and configuration records so maintenance teams can rely on them.
Project checklist
- Use revision numbers and approval status
- Record site changes as they happen
- Cross-check final drawings against labels and tests
Practical takeaways
- Define the operating requirement before choosing products
- Document interfaces, failure behaviour and ownership
- Test the completed system and keep records for support
