Specifications include, but are not limited to: The proposed CAT expansion project is intended to accommodate parking for carriers that serve DAFB as well as to accommodate the parking needs of the occasional civilian charter aircraft as well as the NASCAR race related aircraft for two race weekends (approximately 8 total days) annually. The expanded CAT ramp would be reserved for exclusive NASCAR use on those eight days unless DAFB needs the ramp space and is willing to park NASCAR aircraft on base property. Other than during Race weekends, the facility must be open to provide available services at prevailing cost to any and all non-military aircraft utilizing the airfield. The project would ideally provide parking space for up to four fully loaded Boeing 747 or equivalent size cargo aircraft simultaneously. Figure 1 is a conceptual layout of the proposed project. Proposals for more or less than four carrier spaces will be considered as would the addition of maintenance or similar aircraft related facilities.
