Stair Vignette - Sajjad Alternate Attempt - Testing Tomorrow

Postby jennifer7308 » Mon Mar 05, 2018 11:55 am

Sajjad alternate (program below)- testing tomorrow so any comments would be very helpful. While tight, I think this went ok...minus the doors reducing the stair landings by more than half. If it's a 3'-0" door, and the program requires a 5'-6" stair (based on occupant load of storage level:440/2 X .3 = 66" or 5'-6"), then that means I need 2'-9" further past the extent of the door swing in the landing...which I definitely don't have on the top landing. Am I interpreting that correctly? Is that an automatic fail? I was able to adjust the one to the storage room within the allotted time, but I ran out of time for the top.

Also what's the verdict on L-shape landings? It would mean drawing (2) separate landings side by side, but if I note them as the same elevation is that ok? Or would that negatively impact my score?

Thanks!

--------
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.
