What should the working drawing record?
Illustrative example. Replace the prompts with approved project data and identify unresolved items for the responsible discipline.
| Topic | Input or evidence | Review owner |
|---|---|---|
| Joint | Panel overlap and seal | Fabrication detail |
| Door | Seal, latch and frame | Access detail |
| Penetration | Sleeve, seal and treatment | Interface drawing |
| Removal | Temporary or permanent section | Maintenance plan |
What does the source support?
ISO 8528-10:2022 and ISO 3744:2025 describe measurement methods, not a universal panel construction. The project acoustic specialist selects the applicable performance basis.

What remains an engineering decision?
Cooling, acoustic, structural, fire, fuel and electrical compliance require qualified project review. Only the registered engineer responsible for the job performs engineering sign-off.
Common questions
What else should the bid team know?
Does this guide approve an enclosure design?
No. It is a coordination framework for approved inputs and specialist review.
Can a value be copied from another generator?
No. Use the selected equipment and project design basis.
Who signs off the engineering?
Only the registered engineer responsible for the job.
