This was covered in a recent thread. There are several standards to design to, several in addition to what you noted. Methods consider sprinklered and unsprinklered buildings, on a case-by-case basis. For sprinklered buildings, water demand can be estimated from the sprinkler system bid drawings, which in your case, I doubt were generated. Even with such a sprinkler system demand (including hose streams), most methodologies include a minimum prescriptive demand that considers the building area, occupancy, etc. For large buildings, such as Passenger Terminal Buildings, this minimum will exceed your largest demand area.
I have some of the prescriptive methodologies available, including ISO (not the International Standards Organization). Ultimately, the AHJ makes the call. In your case, they may not want to make the call, but instead want you to defend your decision.
