I was asked to evaluate a warehouse that was built in 1996 for a new racking permit.
The original fire sprinkler system was designed with ESFR sprinklers with a K factor of 14.0. During the evaluation I found that the building peak was 40'-0" tall. Knowing that NFPA 13 no longer allows K-14 ESFR sprinklers in a building over 32'-0", I informed the building owner that the existing sprinklers need to be replaced with a larger-orifice ESFR sprinkler.
The building tenant has tried everything they can to find away around this and does not understand why the building is not grandfathered.
I am just curious if anyone else has encountered this situation and what the outcome was.
