Which markup fields should be recorded?
Number the markup, identify the sheet and location, cite the source, describe the change, assign an owner and record the disposition.
| Field | Question | Disposition |
|---|---|---|
| Sheet | Which drawing changes? | Affected file |
| Source | What authorises it? | Document reference |
| Change | What should be different? | Drafting action |
| Design | Does it alter engineering? | Engineer review |
| Close | Was it applied and checked? | Review status |
Which markups need an engineer?
Route any change to rating, protection, topology, clearance, equipment selection or design responsibility to the responsible engineer. A drafter should not resolve it silently.
- Source revision
- Design effect
- Cross-references
- Reviewer
- Closure evidence
What is the final markup check?
Compare the marked-up sheet, revised native file, review PDF and register. Keep any rejected or deferred markup visible in the history.
Common questions
What else should the bid team know?
What should a drafting markup review include?
It should record sheet, source, change, design effect, owner, disposition and evidence.
Who reviews a drafting markup review?
The drafter applies controlled changes and the engineer reviews any design effect.
Does drafting approve the engineering design?
No. The responsible registered engineer makes design decisions and performs engineering sign-off.
