Interesting how a design issue has now turned into an unreasonable AHJ issue with demands for citations and suggestions for sprinkler locations. Looks like big $ to reconfigure all these mechanical spaces to be able to add sprinklers per their listings and avoid obstructions. Why is the AHJ under the gun to justify and negotiate at this point?
