This project will construct new taxiways that will allow the closure of the existing midfield taxiways in order to build Concourse B. The project includes demolition of existing infrastructure and construction of new airfield taxiway pavement; aircraft-rated bridge structures, service roads, utilities, reconfiguration of the south campus drainage, security improvements and, updates to the airfield lighting and signage systems. Following preliminary engineering, it was determined that additional infrastructure and detailed construction phasing is needed, as well as an additional six months of construction support services for RS&H, their sub consultants and resident project representative oversight. A previous request in December 2023 provided for additional authorization to divide the design into enabling work and airfield infrastructure work packages requiring separate development permits. This current request is for the expansion of the maintenance ramp, which will include utilities relocation and improvements needed for AEDP enabling projects. The proposed midfield taxiways connect to the existing maintenance ramp that is currently used for aircraft remain overnight (RON) parking and accommodations for diverted aircraft. The airport has determined the need to expand the maintenance ramp to relieve aircraft parking positions and operational capacity lost during the construction of Concourse B. This request also included additional pavement work, pavement repairs and additional work within the airfield. Additional Authority in the amount of $6,000,000 is requested for Design and Construction Administration services. If the proposed amendment is not approved there would be a decrease in the Airport’s ability to accommodate RON and diverted aircraft on the Maintenance Ramp. The Department of Aviation has applied for a federal grant under the Bipartisan Infrastructure Law for reimbursement of design and construction phase service fees relating to this project.
