Bob,
I've got a similar situation in a building with residential
sprinklers designed to NFPA 13, only with soffits. Four sprinklers in
a 60 sqft bathroom seems excessive. So far I haven't come up with
anything to let me eliminate sprinklers.

I'm working on a home (13D) that has several rooms with the ceiling broken
up by "beam pockets". These vary in width from 2'8" to 3'3" o.c. with the
beams being 6" deep. Concealed residential sprinklers are being used. In
one room, which is 224 sf, if I place a sprinkler in every pocket like I
think I should, there will be 13 sprinklers. This averages out to 17 sf per
head. Another room is 375 sf and will require 10 sprinklers. This averages
at 37.5 per head. In rooms of this size do I really need a sprinkler in
every pocket? Can a sprinkler be placed in every other pocket and be
acceptable? Has anyone else found a better way to protect rooms like this?
Any and all suggestions will help.
Thanks,
