Safer field move

Never release a prefab package to the shop without a field-verified dimension sheet signed by the person who physically measured it. One wrong field dimension that goes unverified can make an entire day of shop production into scrap.

Ask Foreman

Can you verify this before I keep going? I’m looking at: Cutting an entire prefab duct run to the wrong length because field dimensions were never verified. What’s the approved correction for this job?

Do not

Do not hide, force, cover, or “make it work” if this affects safety, access, airflow, rated assemblies, supports, equipment, or inspection. Stop and verify the approved correction.
