• Egress: 5. The common path of egress travel to the exterior exits exceeds 75 feet for Room 11 and the adjacent rooms, with the longest paths occurring for Rooms 13 and 16. Two exits are required. The maximum exit access travel distance for an unsprinklered 8-occupancy building is 200 feet. The second route for both Rooms 13 and 16 exceeds the travel distance. Note that the route through the Reception Room 01 is not valid as a second path where the first path travels through Door 11A. The egress paths shall be revised. See IBC Tables 1006.2.1 and 1017.2,and IEBC Section 801.3. Response: Our understanding of the code is that the common path of egress is the maximum distance an occupant can travel before having two different exit path options,this is true for the exit path from both Room 13 and Room 16.According to the 2015 International Code Commentary the "common path of travel stops when the occupant has a choice of at least two exits, and overall travel distance stops when an occupant gets to the closest exit"(see attached page). Our understanding of the maximum travel distance is that it is only applied to the nearest exit. In our case both Room 13 and 16 are within 200'from their nearest exit. In the case of the travel path exiting to the south the side lobby is a rated exit enclosure, so the travel distance stops the doors leading to it.The diagram has been revised to more clearly show our interpretation of the code sections. We have also included the relevant section from the 2015 ICC Code Commentary with highlighted excerpts to support our methods attached to this letter. 6.
