sprinklers only in the dwelling units and adjacent corridors. There was a
time when the code permitted the use of residential sprinklers only in

A few notes (please feel free to agree or disagree):
1. No new flow test is required since you're merely calculating system
demand to the BOR.
2. Some older pipe scheduled systems get flagged as deficient for missing
the data plate. However, these systems were never hydraulically calculated

That’s funny as I have in design right now an exterior standpipe that has a
wrap-around stairway so that the landings are separated both horizontally and

available...the only way to reproduce a Hydraulic Plate is to survey the
existing system, produce a set of plans and perform a new set of demand or
