Can you change to ex cov sprinklers? That may be the easiest of options and not have to fight or defend your choice.

Standard response sprinklers for any new sprinklers to match the existing to remain. Hydraulic calculations are required. There are 2 section of corridor, about 35 ft each, that are 16 ft wide and will need two rows of sprinklers. Each section has 6 sprinklers as opposed to 3 if the space was 15 ft or less. These encompasses 70 ft out of the total 760 ft of corridor being renovated. NFPA 13 (2016) gives design criteria for corridors with a single row of sprinklers. However, these two areas have 2 rows, so the calculations would now have to be the full 1500 square feet. That does seem like overkill. Has anyone run into this before? How did they/would they handle it? I have my recommendation, based on “engineering judgement” (which I will post later), but I want to see what others have done.
