Fire Rated Party Walls

tdmyturn

help, We have framed several units with standard concrete to roof fire walls by gapping floor sheathing to accomodate a continuous wall/insul/dbl 5/8 gyp- we now have been asked to seperate the crawl area from the rest of the party wall. ie triplex-dropped floor system on concrete stem walls w/concrete strip dividers needing ponywalls, or post supporting the beam at the party wall- then they specify one continuous run of floor sheathing(all 3 units), then fire wall/party walls. How can you meet fire code at the subfloor and in the crawl space?

Who is the "they" as in "they specify"? The architect? How him/her give you a detail on how you are supposed to accomplish the fire rating.
Seems to me you should be using fire rated plywood at the common floor and roof areas.

the building inspector will help you with what counts as fire rating.

I'm thinking 3/4" gypscrete.
