The architectural specifier or mechanical engineer? David G. Axt, CCS, CSI, SCIP Specifications Consultant Axt Consulting LLC Ronald L.

If there was a need for details showing the bracing of these fans it would normally be considered an additional service by the structural engineer.

Actually, they are pretty cool (pardon the pun). Our biggest concern was not the weight but the vibration and dynamics. https://www.bigassfans.com/ "Fast is good, but accurate is better." .............Wyatt Earp J.

The larger "big ass fans" affect the mechanical design of the project, and on the last several projects I have worked on, the MEP has specified them. J.

Peter Jordan says, Big Ass Fans (TM) are definitely a mechanical item. Residential ceiling fans are in Division 11, and my experience trying to get engineers to prepare sections outside of "their" divisions hasn't been great.
