Stairs on the same floor level

Ewa Szczepanska-Jankowska
February 24, 2012

I have problem with classifying the stairs, that are inside the building, just in front of main entrance, and leads to the mail hall but are still on the same floor. The entrance is just a bit lower than the rest of the buildin (few steps) and there is no mezanine above. Do they belong to Building Service Area or Major Vertical Penetration? Thanks for help,

Probably these steps are Building Service Area. To qualify as a Major Vertical Penetration, there would have to be an opening in the floor/slab in excess of 1 square foot. These sound like just a few steps and not a stairwell.
