Stop if

Hold point on offset layout with construction calculator: I have the location, photo, drawing/detail, and what was checked. Who should verify before this gets cut, covered, lifted, sealed, energized, or signed off?

Watch out

Don't guess offset dimensions. Don't use regular calculator without understanding math. Don't fabricate before verifying all three dimensions.

Check

room/grid/area
photo of condition
drawing/detail
manufacturer/model if visible
what I already checked
