9/28/2017

When you have a sprinkler system with a combined fire and domestic water service, at what point do you separate the plumbing contractor's scope versus the sprinkler contractor's scope, and why?

By no means a definitive answer (or code-based approach), but we typically separate the scope at the system-side flange of the backflow preventer serving the fire sprinkler system. Plumbing contractors regularly install the backflows so it is a fairly easy break-point, although the valves on the backflow still need to be of indicating type and monitored by fire alarm.

That being said, it's on a project-by-project basis if there's a better spot to split the scope. Some contractors prefer that no point is deteremined so that the GC can control and qualify it.
