As far as the sprinkler system is concerned I believe the 2016 edition of NFPA13 added design criteria for two level car stackers. It is now an extra hazard group 2. If you are talking about more than two levels you could potentially use some type of sprinkler arrangement similar to in-racks.

We recently ran into this situation where we have 70+ "suites" where you can store your car(s) and most were to have some type of vehicle lift. The house "shell" sprinkler system was designed to a .20 OH2 density (based off 2013 NFPA 13). The Standard changed, and created a large group of upset owners who cannot use their lifts. We have explored designs similar to "in rack" systems, however no one can get a design to work as they go deep into a negative safety factor.
We've done recently 2 story garage with car stackers (as contractor). We didnt do the design though. Leave a Reply. |
