Which coordination inputs should be registered?
Use vendor outlines, room backgrounds, structural or architectural references, cable routes, access requirements and the approved drawing standard.
| Input | Coordination | Status |
|---|---|---|
| Equipment | Outline and tag | Vendor revision |
| Room | Boundary and doors | Approved background |
| Access | Maintenance path | Project requirement |
| Cables | Entry and route | Interface register |
| Sections | Elevation and reference | Drawing list |

How should a room conflict be shown?
Mark the affected equipment, source, missing decision and reviewer. Do not use a generic clearance or room dimension as a substitute for project coordination.
- Equipment geometry
- Room boundary
- Access
- Cable interface
- Open dimension
What does the GA check cover?
It covers consistency of supplied inputs, tags, references, dimensions and revision. Engineering approval remains separate.
Common questions
What else should the bid team know?
What should a data center electrical room GA include?
It should show equipment, room, access, cables, elevations, tags and source status.
Who reviews a data center electrical room GA?
The drafter coordinates the drawing and the responsible engineer approves the design basis.
Does drafting approve the critical power design?
No. The responsible registered engineer makes design decisions and performs engineering sign-off.
