CONRAC & QTA BUILDINGS

[SRK_Mech]

I'm looking for feedback related to Consolidated Rental Car Facilities (CONRAC) and Quick Turnaround Buildings (QTA): Anything and everything related to codes and standards that are applicable. I'm more interested in the QTA than the CONRAC building because of the nature of having fuel dispensing on multiple levels of essentially a "multi-level, unenclosed parking garage" type building. The QTA I'm interested in proposes multiple floors. The gasoline, now I'm guessing here, is stored in underground storage tanks, one per rental car company. The fuel is pumped to the rental car company depending on which floor they are located on. I'm assuming the building will be set up with fire sprinklers, too.
