Base Building Circulation or Building Service Area - basement circulation

Modern Out West
March 15, 2022

I'm using Method B on the Basement Level of a multi-story building. The level consists of a Building Amenity Area, Occupant Storage Areas, Floor Service Areas, Tenant Areas and Building Service Areas. Would the main circulation areas be considered Base Building Circulation or Building Service Area? The main entrance and lobby are located on the floor above.

Hi Candice,

It's difficult to say exactly without seeing the floor plan, but in general, Base Building Circulation should be drawn on every tenanted floor. The standard does state an exception:

On some Occupant Floors (especially Publicly Accessible Floors), BBC will not be
applicable if access to Tenant Areas is provided via Building Service Area and the
extents of Tenant Areas are unlikely to change over time.

Base Building Circulation (BBC) should only be drawn in areas that are not permanent, so consider including BBC within any existing non-permanent multi-occupant corridors and other non-permanent areas that could provide multi-occupant circulation where there are no corridors currently.
