I would surmise that the 8 foot minimum distance is to prevent 'cold soldering'. The I-beam pockets preclude this from happening, therefore this restriction is non applicable to the design problem.

This building may not be suitable for ESFR.

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?
