I mean on the lobby level to level IC.
Adding transfers to the lobby levels are very unrealistic, unless you are meaning emergency exit hallways. As far as that is concerned I might add those to the IC level, since I plan for the south half of the IC level to be service tunnels. These exit tunnels will intersect the service tunnels, but locked doors will cordon the service tunnels off. The emergency exit will lead to a staircase that goes up to the street. The emergency exit will also serve as the service entrance/exit. I will get into more detail with this planned design of the IC level when I am working on it.
How many zones are there for the building?
There are five zones...
1. Zone 1 (Floors 42 and below)
2. Zone 2 (Floors 43 to 88)
3. Zone 3 (Floors 89 to 137)
4. Zone 4 (Floors 138 to 161)
5. Roof Section (Floors 162 and up)
Also, where and how many transfers are there?
There will be 5 stairwell transfer hallways. Two on the 42nd floor, two on the 88th floor, and there will be one on the 137th floor where the Zone 3 East and West Stairwells come together into the Zone 4 Central Stairwell.
