Which handover files should be indexed?
Use one row per drawing and link the source inputs, output files, reviewer, revision and status. Keep rejected or deferred comments visible in the record.
| Group | Record | Status |
|---|---|---|
| Register | Sheet list and revisions | Current |
| Native | Editable drawing files | Handover |
| Review | PDF output | Compared |
| Source | Markups and schedules | Linked |
| Open | Outstanding design items | Owner assigned |
How should an open design item be handed over?
Name the affected sheet, source, decision owner and next action. A handover should preserve uncertainty rather than implying the set is fully approved.
- Affected drawing
- Source and revision
- Open decision
- Reviewer
- Next action
What does handover not mean?
It does not mean construction approval, engineering certification or final commissioning acceptance. Those are project gates.
Common questions
What else should the bid team know?
What should a data center drafting handover include?
It should contain register, native files, PDFs, sources, revision history, comments and open design items.
Who reviews a data center drafting handover?
The drafter prepares the record and the responsible engineer or project team approves the next stage.
Does drafting approve the critical power design?
No. The responsible registered engineer makes design decisions and performs engineering sign-off.
