A plan offset is not proof the offset fits in the ceiling. Verify real space, elevation, and the working length before layout.

Field checklist

Find the offset on plan and section.
Check available length in the field.
Compare with ceiling, beams, sprinkler, cable tray, lights, and insulation.
Use the offset calculator if needed.
Ask if the offset would be too tight or ugly.

Ask foreman

This offset is shown on plan, but the real space is tight. Do you want a revised route/detail?

Do not

Do not build the drawn offset blindly when the ceiling space is different.

Why it matters

Offsets are 3D problems even when the drawing looks flat.
