Focus on the actual issue: VAV box installed without access clearance.
Photograph or mark the condition if someone else needs to approve it.
Ask foreman
In Equipment Connections: RTU, AHU, VAV, Fans & Louvers, I’m looking at: What do I do when VAV box installed without access clearance? What should I verify before I cut, drill, seal, cover, move, or install?
Do not
Do not bury the controller, coil, damper, or access side behind duct, flex, insulation, or hangers.
