With a 36' high building, the max spacing would be 10' apart and the esfr is 6' apart due to the beams. This is a 60 sq. ft. coverage area. The esfr cut sheet state a minimum area of 64 sq. ft., 64 sq. ft. x (12) esfr is 768 sq. ft. minimum design area, would you have to add an esfr fire sprinkle in the calc to meet the 768 sq. ft. area or esfr are not allowed due to not meeting the 64 sq. ft. minimum per esfr sprinkler?

The sprinkler design is asking for ESFR but I am not sure if this will work, I know we can use ESFR in obstructed construction but my understanding is the heads location still needs to comply with the listing. So based on this I would need a head in every bay created by the beams and the head would need to be 14" or 18" max from the deck. Am I missing something?
