Hello to All. Doing a plan review of a new construction college residence hall, [R-2]. Designer has used the exception in the FCNYS D105.1 to avoid having to have aerial fire apparatus access road. The exception states in part ...
and having fire fighter access through an enclosed stairway with a Class I Standpipe, in conformance with NFPA 14, from the lowest level of fire department vehicle access to all roof surfaces.
Designer shows access to the roof via an enclosed 2-hour rated stairway that opens to a 1-hour rated corridor that leads to another door that leads to the roof. Is this acceptable or does the roof access has to be from the enclosed stairway directly to the roof?
Also there is a lower roof that shows access via the same 2-hour rated stairway to the 1-hour rated corridor to a window. Is this acceptable and compliant with FCNYS §D105.1 exception?
