Trying to figure out a three level , fully sprinklered underground parking garage under a mercantile/ business occupancy. The lowest level will be some 40 ft below the LED.
Such a parking garage would meet the definition of enclosed parking , so the provisions of IBC 405.4 do not apply.
Following the IBC flipper ball up and down, it seems that for S-2 occupancies, if the construction type is type II-A we can have 117.000 sq. ft each level and if the construction type is I-A we have no limits on the allowable area factor, am I reading the Code correct?
If this is the case, how do we approach the ramps leading from one level to the other? Do we need to install something like fire rated curtains? What happens to drivers trying to drive to the next level after fire curtain activation?
