Existing 5A building with load bearing exterior CMU walls. A proposed addition turns the existing load bearing exterior wall into an interior load bearing wall, which requires a 1 hour fire rating (due to building type.) The addition will be comprised of three rooms, each accessed from existing individual rooms: proposed 180 sf office storage via an existing office, proposed 180 sf storage room via an existing police station interview room, and a proposed 180 sf office via an existing room (with existing exterior egress door).
What type of wall assembly is this CMU load bearing wall supposed to be - a fire barrier or a fire partition? At the moment, the existing CMU wall extends above the existing rated ceiling and the trusses sit on top of the wall. The existing CMU will extend above the proposed rated ceiling / roof assembly.
Thanks
