High-rise office building, predominantly light hazard occupancy. Water supply is designed for a 30 minute duration (roof mounted gravity water storage tanks).
We need a 1-hour separation between two tenant spaces. The architect has specified a glass partition. As such closely spaced heads are being proposed to achieve an equivalent rating.
Does the water supply now need to be upgraded to provide a 1 hour supply of water?
Similarly, if sprinklers are being used to provide an equivalency rating on a required 2-hour rated partition, does the water supply need to be able to supply 2-hours of demand?
