In a school restroom remodel, we're going to demo through an existing 2hr rated concrete filled metal deck to install a Zurn Z415N floor drain, see attachment. DSA will require us to provide a firestop solution.
Hi Michael - the closest system we would have is F-A-1137, but for your drain we would recommend requesting for an engineering judgment. You can submit this request following the instructions below.
Hilti is proud to announce the launch of our engineering website, the HILTI CONSTRUCTION PLATFORM (HCP). This platform will be the home for all of your Fire Protection Engineering needs, including Engineering Judgment requests. You can find more information on how to access this new platform here: https://www.hilti.com/ej (US) or https://www.hilti.ca/ej (Canada.)
Regards,
Nate Crawford - Lead FPE
