Which decisions belong to design and drafting?
Write the responsibility split into the drawing list and review plan.
| Topic | Design owner | Drafting output |
|---|---|---|
| Cooling | Mechanical engineer and vendor | Approved air path and openings |
| Noise | Acoustic specialist | Approved treatment details |
| Structure | Structural engineer | Connections and dimensions |
| Electrical | Electrical engineer | Cable and control interfaces |
| Issue | Registered engineer | Checked drawing files |
What should the input pack include?
The Cummins ventilation manual lists combustion air, heat removal and fume removal as ventilation purposes. The manufacturer data, selected equipment and project constraints should therefore accompany the GA inputs.

Common questions
What else should the bid team know?
Can a drafter set the ventilation rate?
No, not without an approved design basis from the responsible professional.
Can the drawing show an open item?
Yes. Mark it clearly for review and record the owner.
Who signs the engineering?
Only the registered engineer responsible for the job performs engineering sign-off.
