One additional issue to keep in mind is required ventilation, specifically testing and balancing. Its important to confirm with the mechanical engineer that said objects will not effect mechanical operation pursuant to 2003/2006 IMC 403.1(ventilation) & 403.3.4 (balancing)

Does anyone know of something in the Mechanical Code that would prohibit steel fire sprinkler pipe from passing through mechanical ductwork? Case in point, 2 1/2" fire sprinkler line passing through a +/-60" square duct. Mechanical contractor would seal the penetrations. Thanks, Gregg Fontes Cen-Cal Fire Systems, Inc.
