Greg- What Cliff said. 500 for the first and 250 for each other for your standpipe hydraulics up to 1000 or 1250, depending on sprinklers. Tom
Greg, If have understood your description, these are called 'scissor stairs' and are fairly common in condos in south Florida. As far as I am aware, there is no way to get rid of one of them. They are required in each stairwell. As far as the calcs go, you would calc this the same way you would if they were separated by 100 ft. It is a completely different standpipe as far as the code is concerned. Cliff Whitfield, SET Does anyone have experience with standpipes serving a building where there is an "up" stair and a separate "down" stair adjacent to each other. Both serving the same floor area or fire zone. The EOR is asking for a s/p in each stairwell. Do you have to calc 2 valves on the same floor? Or can you calc one valve per FLOOR? Is there a legit way to eliminate one of the s/p's?
