Which controls belong in the process?
Use a drawing register, controlled issue folder, revision record, review comments and transmittal. Keep the native file and review PDF linked.
| Control | Purpose | Evidence |
|---|---|---|
| Register | Current set | Sheet list |
| Revision | Change history | Revision note |
| Source | Input trace | Markup or schedule |
| Review | Comment closure | Response record |
| Issue | Released status | Transmittal |
What should happen when a source changes?
Identify affected sheets and schedules, update the change action and route the set for the required review. Do not overwrite an issued file without a new controlled revision.
- Impact scan
- Affected sheets
- Updated source list
- Comment response
- New issue record
What remains with the project team?
The project team defines issue status, approval and retention. Drafting supports the record but does not grant engineering approval.
Common questions
What else should the bid team know?
What should a HV document control include?
It should control identity, revision, source, review, issue, transmittal and superseded history.
Who reviews a HV document control?
Document control owns the system and the responsible engineer owns technical approval.
Does drafting approve the engineering design?
No. The responsible registered engineer makes design decisions and performs engineering sign-off.
