We have an application for an indoor soccer facility that the applicant is proposing in an existing 14,000 sf building. The field alone is approx 11,000sf. Using the factor of 50 ("exercise" from T1004.1.1) that gives us an occupant load of 220. While I understand that in reality 220 people will not be on the field at the same time I would like to see a higher occupant load then the 14 that the applicant is proposing (6 on ea team with two refs). I know that indoor soccer facilities typically host b-day party's, end of the season party's etc which usually ends up with full teams and parents out there running around. In addition, you have the spectator seating which in this configuration I calculate at approx 120. My question is per the Exc of IBC 1004.1.1 what is a reasonable way to determine the occupant load for the field? Our zoning code requires the number of parking per the occupant load determined by the building code - they would have to add a lot of parking... On the plus side the building was constructed in 2008, sprinklered, panic hardware, exit signs, emergency lighting, 4 exits, etc.
