I have a scenario where there are multiple conduit penetrations through a 2 hour assembly (not shaft wall - 2 layers rock both sides of wall) and I cannot access one side due to the conduit already being tied into an electrical panel with wire pulled through them. Is there a detail that shows how to fire rate these conduits from one side of the wall???
Good afternoon Andrew,
We do not have a tested system for a one side install of multiple conduits installed in a gypsum board wall assembly. We can however create an Engineering Judgment for this condition depending on the other details of the condition. Below are links and instructions for how to request an Engineering Judgment through the Hilti Construction Platform:
We are proud to announce the launch of the HILTI CONSTRUCTION PLATFORM (HCP), our company’s new engineering service website. This platform will be the home for all of your Fire Protection Design needs. Instead of emailing a PDF form for a request, the platform enables you to create new Engineering Judgment (EJ) requests, submit revisions to previously completed EJs or connect with an FPE on a question. HCP also enables you to track the status of your request.
You can find more information on how to access this new platform here: http://www.hilti.com/ej (US) or http://www.hilti.ca/ej (Canada.) If you have any questions or require assistance navigating the platform, please call Customer Service for help at 1-800-879-8000 (US) or 1-800-363-4458 (Canada.)
Along with HCP, Hilti is excited to announce our new mobile app for all your firestop needs: Hilti Firestop Selector. Using the Firestop Selector app gives you easy access to the Hilti Fire Protection Design Team from the jobsite, on the road, or in the office to request a new EJ, an EJ Revision, or a Question anytime, anywhere. You can download the app using the appropriate link below.
