Won Door

[cda]

So have not done a new Won door in forever. Use to like them.

So say the occupant load going through the Won Door is 800.

What is the answer to item 8 below???

"""minimum required width"""


1010.1.4.3 Special Purpose Horizontal Sliding, Accordion or Folding Doors

IBC 2018 1005.3.2. Calculation is occupant load times a factor of 0.2 inch. That is not for stairway, just "other egress components." It has 3 exceptions so read those to see if they apply to your situation.

Hope this helps.

Nicely done JRice....first post and you are spot on. What industry are you joining us from? I'd say welcome, but looks like you have been a member for almost 10-years now.

1005.3.2 Other Egress Components
The capacity, in inches, of means of egress components other than stairways shall be calculated by multiplying the occupant load served by such component by a means of egress capacity factor of 0.2 inch (5.1 mm) per occupant.

Exceptions:

1. For other than Group H and I-2 occupancies, the capacity, in inches, of means of egress components other than stairways shall be calculated by multiplying the occupant load served by such component by a means of egress capacity factor of 0.15 inch (3.8 mm) per occupant in buildings equipped throughout with an automatic sprinkler system installed in accordance with Section 903.3.1.1 or 903.3.1.2 and an emergency voice/ alarm communication system in accordance with Section 907.5.2.2.
2. Facilities with smoke-protected assembly seating shall be permitted to use the capacity factors in Table 1029.6.2 indicated for level or ramped aisles for means of egress components other than stairways where the entire path for means of egress from the seating to the exit discharge is provided with a smoke control system complying with Section 909.
3. Facilities with outdoor smoke-protected assembly seating shall be permitted to the capacity factors in Section 1029.6.3 indicated for level or ramped aisles for means of egress components other than stairways where the entire path for means of egress from the seating to the exit discharge is open to the outdoors.
