We need a detail for a 8" CMU block wall I.T. chase that can only realistically be accessed from the outside as all sides are built up around a column to enclose data conduits. It would be a 2-hr rated concrete block wall assembly/vertical chase, installed against a precast column, in a garage spanning between cast-in-place floors. (Reference the attached drawing)
Secondly a wall-to-wall joint detail would also be useful for the where the CMU block wall contacts the precast column (Also one-side access).
Thank you for your help in this matter,
Hello,
Hello, I've attached a few systems that I believe meet your needs based on the conditions of your request. If none of these will work for you, please submit an Engineering Judgement request and we can see what solutions we can create for you and let us know why these systems do not work in the request. I've provided the information on how to submit a request below.
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.
Hilti Firestop Selector App – Google Play Store
