Big picture question here - I am working on an airport project. We have a Passenger Terminal Building and Aircraft Stands adjacent to the building.
I need to provide sprinkler protection with fire hose cabinets in the Passenger Terminal Building (1,000 gpm at 8 bar / 100 psi), AND fire hydrants to resupply the aircraft rescue and firefighting trucks (1,500 gpm at 6 bar / 87 psi). Do both of these demands need to be considered together to size the fire pump (both flows combined)? We are considering one duty pump and one standby pump. Thanks in advance.

Typically hose demand for standpipes/hoses does not get added to fire flow demand for fire hydrants. That being said, this sounds like it might be a unique situation. What version of IFC and NFPA 14 are applicable? 3/3/2020 11:51:48 am
Most codes consider one fire scenario at a time. Therefore, select the pump for the scenario with the highest flow requirement.

As usual, the answer is « it depends ».

I've done a few projects like this in MENA. These didn't have any public water infrastructure so we ALWAYS combined the flows.

You can add both together as long as if you can hydraulically prove the pressure requirement in the system does not exceed the hydrostatic test pressure of components, fixtures,fittings, material where test pressure shall be well within 200 psi or 350 psi as allowed and corresponding working pressure of 175 psi and 300 psi respectively.
