Lập kế hoạch & Dự toánCâu 291 / 360
You must coordinate a 4-inch sanitary line and an HVAC duct that cross in a tight ceiling. What is the best planning step to resolve the conflict before installation?
a.Install whichever trade arrives first and let the other adjust
b.Cut the duct on site without telling anyone
c.Ignore it since pipes always win
d.Compare the trades' drawings (or a coordination/BIM model) to reroute one system and preserve required clearances and drain slope
Giải thích
Overlaying the plumbing, mechanical, and structural drawings, or a coordination model, reveals clashes so one system can be rerouted on paper. The drain must keep its required slope, so it usually sets the elevation and the flexible duct moves. Resolving clashes before installation avoids demolition and schedule delays.
