In your opinion, what's the best way to address sprinkler design when there are open breezeways separating units in the same building?
Do you somehow provide a heated chase under a deck? Convert from CPVC to steel and heat-trace a run? Go back underground and potentially "under" the building? Use separate risers for each grouping, bumping up the price significantly?
Residential multi-unit apartment complexes are frequently built with open breezeways in-between blocks of units. These usually have paved concrete at the bottom, only wood joists and decking for stairways and walking areas, and a covered roof at the top.
