The stairways and landings in the Type I portion of the building should be constructed of non-combustible construction.Section 1011.7 Response: We propose that Stair A remains wood as it extends through the IA portion of the building. We feel that the purpose of a shaft is to confine a fire to the floor of origin and to prevent the fire or the products of fire from spreading to other levels. It is our understanding that the code is moving in this direction and the next round of code revisions will incorporate this opinion into the base code. Graphics have been improved and notes added to indicate that the remaining stairs in type IA construction are to be pre-engineered metal stairs or cast concrete. See revised details sheet A-7.2. 10.The exit passageway portion of Stair B should be shown with 90-minute doors (101, 102 & 114) and minimum two-hour walls(wall type C-2-2 is not a two-hour rated wall due to the one-hour partition on top of the CMU).Section 1023.3 Response: See the revised Sheet Door Schedule sheet A-2.7.
