Safer field move

Any time a field deviation occurs — duct rerouted, fitting substituted, elevation changed — mark it on the red-line set immediately. As-builts that don't reflect reality cause commissioning failures and expensive investigations.

Ask Foreman

Can you verify this before I keep going? I’m looking at: Failing to mark up as-built changes on the job drawings. 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.
