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.

Stop if

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

Watch out

• Do not install duct from the ceiling plan alone.

Check

• 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.
