Stop work on that room segment. Do not install your deep duct runs if they will stick out below the level of the new architectural drywall layout tracks.

Plain-English answer

Stop work on that room segment. Do not install your deep duct runs if they will stick out below the level of the new architectural drywall layout tracks.

Measure the real clear vertical space remaining from the bottom of the structure to the new low-ceiling track. Inform your foreman immediately so they can coordinate a system redesign with the mechanical engineer to split or flatten the duct profile to fit the new ceiling height restriction.

Ask Foreman

Hey boss, I’m checking trade coordination: What do I do if the architectural ceiling is dropped lower than the plans state? I found the likely issue and want to verify the next step before I lock it in. Do you want me to adjust it now or check the drawing/detail first?

Verify before acting

Use this as training guidance. The foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, and AHJ/code requirements always control the final answer.
