Sajjad’s Stair Alt. Program

plans are being developed for a new exit located within an existing stairwell in a two-story Administration Building. The design for the other building exits -- a second stairway and the building’s main entrance -- has been completed.

1. Design the stairway to serve as a means of egress from all three building levels leading into the stairwell and through the exit discharge door to the sidewalk at grade (a public way).
 The stairway must provide a continuous path from Second floor to Ground floor exit that includes a landing at the Intermediate level.

2. The total occupant load and number of exits for each level of the building are as follows:

Building Level Total Occupant Load Number of Exits
Ground Floor Level 5 1
Storage Room 440 2
Second Floor 320 2

3. The stairs will be constructed from precast concrete components with the following dimensions:
 Landings: 9 inches deep between the landing soffit and the surface.
 Stair flights/stringers: 12 inches deep between the stair nosings and the stringer soffit measured along a line perpendicular to the soffit.
