When determining the available ceiling space for a duct run, what should you consult?

Consulting the structural drawing for the floor above is crucial when determining the available ceiling space for a duct run. These drawings provide detailed information about the building’s framework, including the locations of beams, columns, and other structural elements that can affect the routing of ductwork. By understanding the structural components and their dimensions, you can identify feasible pathways for the duct run while ensuring compliance with building codes and regulations.

Other sources, like architectural layout plans, offer insights into design intent and aesthetic considerations, while electrical drawings focus on wiring and electrical systems. HVAC specifications, on the other hand, outline requirements for heating, ventilation, and air conditioning systems but do not detail physical constraints like structural drawings do. Therefore, the structural drawing becomes the most relevant resource for assessing available ceiling space effectively.
