Architectural Duct Mockup and Installed Work Do Not Match

The installed exposed duct uses a different screw pattern and hanger finish than the approved mockup. I documented both. Which condition controls before the crew continues this area?

Stop if

Stop before changing structural support, rated construction, equipment handling, specialty materials, weatherproofing, engineered movement details, or manufacturer-specific requirements without the responsible direction.

Watch out

Do not continue hundreds of feet based on “close enough” or alter the approved mockup without documented direction.

Check

current drawings and approved details
grid/floor/location and measured conditions
photos showing the installation condition
relevant manufacturer, structural, architectural, or finish information
what has already been checked
