How should the checklist be retained?
Attach the completed check to the issue record and keep the source register with it. Any unchecked item should be assigned before the drawing is issued.
| Control | Evidence | Owner |
|---|---|---|
| Source | Markup and schedule register | Drafter |
| Coordination | Tag and interface check | Drafter |
| Engineering | Review status | Responsible engineer |
| Issue | Transmittal or record | Document control |
What does the tool not approve?
It does not approve protection logic, clearances, ratings, safety controls or construction suitability. Those decisions remain with the responsible project team.
Common questions
What else should the bid team know?
Does drafting decide the substation design?
No. Drafting turns approved engineering inputs into controlled drawings. The responsible registered engineer makes design decisions and performs sign-off.
Can a drawing set use any symbol library?
Use the project drawing standard and approved symbol convention. Where a standard is specified, the project team confirms the applicable edition and licensed access.
What happens when a dimension is missing?
Show it as an open input or request the approved source. Do not invent a clearance, rating or equipment outline.
