Field checklist

Ask Foreman

Hey boss, I’m checking advanced problem solving: The engineer specified a VAV that is physically larger than the ceiling space provided. What are my redesign options? I found the likely issue and want to verify the next step before I lock it in. Do you want me to adjust it now or check the drawing/detail first?
