Re: NFPA 101
a 21 Level High Rise Apartment building has a 1 hour roof slab. On top of the roof is a fixed dome. The building is a class 2, 222 type
Does the dome have to be fire rated?, The Dome structure frame is steel framed with a hard cladding and has openings to the elements. the floor of the dome is the roof of the building and at roof level has a number of arches which allows personnel (maintenance staff) to pass through the dome. the Dome height is around 8 meters high from the roof level at the base.
The building is 26 floors.
