I am working on a project where an old mill is being converted to
condos. The building is 500 feet long and there is a central corridor
with units on either side. We have been asked to install hose
stations at three locations in the main corridor, fed from a separate
standpipe from the basement. These will be no where near the stairtowers.
Due to the location of the hose connections, there is no way that a
hose connection on level 2 could ever be used for a fire on level 3.
In the hydraulic calculations, do you still need to include 250 gpm
from each of the top two outlets on the first standpipe?
Also, each standpipe is to be fed from a different riser, so the
connection of the three would occur in the underground. Do you still
need to calculate the demand that includes all three?
