Multi-Occupant Corridor

Leslie Kiriakos
February 4, 2016

On page 25, multi-occupant corridors are defined as a portion of the floor service area in Method A. However, it may also be included in extended circulation in certain circumstances. What is an example of a circumstance where it would be classified as extended circulation and thus occupant space?

Also - if a corridor may not be exclusively controlled by a full floor occupant - am I correct in categorizing the corridor as a floor service area?

At NOAA we have multi occupant floors. The corridors on each floor are not exclusively controlled by a single occupant as we encourage collaboration between the different organizations. Should we, then, classify all corridors as Service?

Thank you for your assistance.

Hi Leslie,

We utilize Extended Circulation when a portion of a corridor system extends beyond the required corridor that normally serves all the occupants on the floor. Most of the time, this is a corridor that is specifically built for a specific tenant or to specific tenants.

If a corridor is not exclusively controlled by a full floor occupant, it should normally be Floor Service Area or perhaps Building Service Area if it happens to provide some sort of building egress.

Your multi-occupant floors should be Floor Service Area or perhaps Building Service Area if it happens to provide some sort of building egress.

Thanks and sorry for the delay responding.
