I think I referenced this project in a previous post, but I have now got the whole place mapped out (I think) and need some input on solutions.
The facility is a hospital. The interconnected buildings range from 1 to 6 stories on a side hill. On the south side, you enter at floor 1; the north side floor 3. Three separate lead-ins, two non-interconnected connections to the public supply. The building is only partially sprinklered. Static pressure is approximately 60 psi There are multiple standpipe/hose valve connections. Some, but not all, are fed from dedicated standpipe lines. Hose valves in cabinets in hallways. 6th Floor - no hose connections (mechanical and support areas only) 5th Floor - one 2-1/2" valve, one 1-1/2" valve 4th floor - three 2-1/2" valves, one 1-1/2" valve 3rd Floor - four 2-1/2" valves, one 1-1/2" valve 2nd Floor - four 2-1/2" valves, three 1-1/2" valves 1st Floor - five 2-1/2" valves, two 1-1/2" valves. Some 2-1/2" valves have 1-1/2" reducers, some do not. Most all riser piping is buried behind the walls and not in stairways. Not easily accessible for replacement One riser goes 5 floors, some go three, some valves a fed from horizontal mains on floors where the service enters. They are being required by the State to test the standpipes. My task is to figure out the standpipe criteria and design a system so that the criteria can be met. Any thoughts on what the design criteria would be for this system? Todd G.
