The main point is that for standard high rises, the codes and standards only require a single riser.
Very Tall High Rises (>420 ft) are a unique beast. The IFC requires these tall buildings to have 2 risers per zone. Not 100% sure but I don’t think they mean each floor is a zone. The same section says “Each riser shall supply sprinklers on alternate floors”. A lot of these building going up in parts of the Middle East but not hearing about any here in the USA. Any one involved with one?
