My reply would be to do one of two things. 1) install a flat non-comb. Drop ceiling at the 34'height 2) Pay for a FPE to spec./design and seal the drawings for the building as built.

There is also a 20 ft maximum limit for distance from the top of storage to the roof sprinklers but I don't know if applies when there are in-rack sprinklers.
