How do I run restraints for ductwork in fire rated hallways?
ANSWER:
This is a great example of the need for good phasing on a project. It may be that the restraints have to be installed crossed over the top of the ductwork and before the walls are put in place. It may mean that rigid supports will need to be used in lieu of a cable restraint system. The options should be considered and a method chosen with the assistance of a qualified seismic design engineer.This is a great example of the need for good phasing on a project.
