What do I do when installing from architectural ceiling plan instead of mechanical plan?

Use the mechanical plan for duct routing, not the architectural ceiling plan alone. Ceiling plans help coordinate openings, not define duct install by themselves.

Field checklist

Check the mechanical sheet first.
Use reflected ceiling plan to coordinate grilles, lights, grid, and access.
Compare mechanical and architectural sheets for conflicts.
Check sections/details.
Ask which drawing controls if they disagree.

Ask foreman

Mechanical and architectural sheets disagree here. Which one controls this duct route?

Do not

Do not install duct from the ceiling plan alone.

Why it matters

Architectural drawings show finishes; mechanical drawings show the duct intent.
