Max Common Path of Egress Question for Structures connected by a Exterior Covered Walkway

[apas62772]

I am a young architect trying to understand the path of egress and applicable codes for a building arrangement I have not yet encountered. See below, the stand alone structures that are connected via by exterior covered walkways. Each structure is divided up by individual rooms and the only egress for these rooms are out to the outdoor walkways, where the occupancy is more than 49 there are two exits out of the respective room.
The attached diagram assumes an occupancy of 500 for each floor.

1. I am only familiar with 1004.7 IBC 2021 are the exterior covered walkways considered an outdoor area.
2. How is the path of egress and applicable egress codes considered because we are exiting to the outside from each room? Are the covered walkways part of the path of egress in this case?



What happens when we have a lower level, and there is a dead end. The yellow boxes represent stairs,
3. I assume the path of egress distance between stairs 1 & 2 has to be less than what is shown in table 1006.2.1 of IBC 2021, the Max. Common path of egress, even though occupants are exiting to the outside?
4. The distance between stair 2 and A has to also conform to the Max. common path of egress correct?
5. Can they use stair one to go up for egress in a panic situation, assuming stair 1 is wide enough?

The first thing you need to understand as a new architect is where it is appropriate to post a question like this. I am moving this thread to the correct location.

Please revise your key plans to show where the street and/or public ways are.

Are the two stairs shown enclosed exit stairs, or are they exit access stairs? Why are the stairs shown on the lower level but NOT shown on the upper level? Why are there two stairs on the lower level even though one end is open? And how can the right end be open on the lower level AND open on the upper level? That would appear to be impossible.
