IGA Boundary at Public pedestrian thoroughfare and colonnade

Peter Ducas
OTJ Architects
March 26, 2015

I have a building that has a ground floor level that is set back 10' from the rest of the building (floors 2-10). The 2nd floor is supported by columns extending from the 2nd floor exterior face and there is a public pedestrian thoroughfare that runs between the 2nd floor support columns and the 1st floor glass exterior window wall (very similar to illustrations 10.3 and 11.3). This PPT does not meet the requirement for external circulation since there is access to the 1st floor spaces from within the building as well. Can this area between the columns and the 1st floor building window wall be included in the IGA boundary (and therefore be calculated as part of the tenant area)? The landlord's consultant is convinced that it can be included.

Hi Peter,

No, you cannot include the unenclosed area between the columns and the window as part of the IGA. However, the IGA boundary should be to outside surface on the side of the building with the Public Pedestrian Thoroughfare as per illustration 10.3.

The only unenclosed areas that may be included in the BOMA 2010 Office Standard are External Circulation, Exterior Door Setbacks and Unprotected Exterior Opening.
