Field checklist

Check wall/ceiling opening dimension and location.
Compare with drawing/detail and sleeve/firestop requirement.
Verify finished wall/ceiling thickness.
Confirm whether the opening is ready.
Ask before cutting, forcing, or changing duct.

Ask foreman

Is this wall/ceiling opening verified and ready for this duct size and detail?

Do not

Do not hang duct assuming the opening will be corrected later.

Why it matters

Wrong openings turn into rework, finish damage, sleeve/firestop issues, and schedule fights.
