I have a healthcare building owner (five story building) who is doing a small remodel to about a third of a single floor. The existing sprinkler system is being modified (relocated and demo/new sprinklers) to accommodate the wall and ceiling changes.
The existing building is Seismic Design Category D, requiring seismic bracing, but the existing system has none. My recommendation to the owner (which aligns with their insurer's recommendation) is for retrofit of the whole floor if not the whole building.
The owner is looking to provide seismic bracing on only the system being modified.
Does this provide any benefit at all?
My concern is that without adequate bracing what is provided could possibly provide zero benefit or even make the system worse if part is fixed and another is not.
