The fire flow estimates the amount of water needed (or in other words, the 
amount of water that will be provided) at the hydrant for fire protection 
purposes which will include manual firefighting and/or automatic fire 
protection (sprinkler/standpipe). While the sprinkler calcs (typically) start 
at the available hydrant and size the pipes internally for the automatic 
sprinkler system.

Definitely out of our control but I was looking for the differences between the 
(2) calculations. I know the fire flow takes into account the building 
construction, adjacent structures, etc. etc. etc.

Check the IBC/IFC (index... not sure what section). Fire Flow is the amount of 
water required to be delivered by the fire hydrants for the FD to spray on  a 
burning building. The amount required is dictated by the code, but the actual 
water available is determined entirely by the underground piping. Unless you 
are providing or designing the underground loops around the building, it is 
probably out of  your control.

Subject: Fire Flow vs Hydraulic calc's

Can someone please put into laymen's terms the difference between doing a fire 
flow demand calc for the underground and the hydraulic calc's for the sprinkler 
system? We have been running into some projects lately where the civil engineer 
tries to pawn sizing the underground off onto the sprinkler contractor. I try 
telling them that's their responsibility not ours but I'd like something more 
definitive to have on hand.
