The South Ramp Expansion Program for Charlotte Douglas International Airport (also referred to as “CLT,” “Airport,” or “Owner”) consists of the design and construction of a three-phase program targeted to enhance capacity and improve efficiency of the terminal ramp by addressing ramp congestion, improving taxi times and enhancing safety. South Ramp Expansion Phase I will provide unimpeded dual Airplane Design Group (ADG) III and V taxilanes for the southeast area. Phase II will provide continuity of the unimpeded dual ADG III and V taxilanes for the center area of the ramp. The program also provides for the relocations of the Airport Surveillance Radar (ASR) and of the Center Lighting Vault, the two projects that are the subject of this RFQ. Finally, Phase III will complete the linear and unimpeded taxilane connectivity for the southwest corner of the terminal ramp.
