Ok. I'll try not to embarrass myself again. This vignette corresponds to the program below. Please comment.

Sorry about the poor quality (Vignette software won't let me get to the snip tool, don't have a graphics software to past prnt screen to)

Thanks.

Sajjad’s Stair Alt. Program
SUGGESTED TIME: 1 HOUR

In order to meet new accessibility standards and increased occupant loads, schematic 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.


CODE
Use the written stair code provided with the NCARB problem.
