Barnhart Balfour Beatty is currently providing construction management services for the new Improvement Program (IP) at John Wayne Airport (JWA)to include extensive renovations and new construction. The scope of work includes managing the design and construction of the new $44 million 2,040-space Parking Structure B1, a $26 million new Central Plant/Cogen Facility and an Airside Dock Access (ADA) and trash facility.
The Improvement Program represents the first major renovation to the airport in nearly 20 years and it is expected to be completed and in full operation by late 2011.
Parking Structure B1
The existing parking structure will be demolished to make room for the new construction of Parking Structure B1. The structure will include approximately 2,040 new parking spaces on five levels to help meet the current and future capacity needs of the airport. The structure consists of approximately 740,000 SF of post-tension concrete and buckling-restrained bracings (BRBs). The steel beams have a core plate covered with restraints to keep them from buckling. The material will allow the structure to withstand greater forces, such as earthquakes, than a typical concrete beam structure.
There will also be a pedestrian bridge on the third level of the parking structure, which will provide pedestrian access to the terminal.
Central Plant/Cogen Facility
Barnhart is also managing the design and construction of the new $26-million, 10,800 SF Central Plan/Cogen Facility that will furnish power to the existing Terminal A and new Terminal B when completed. The project consists of a single-story building that includes a mezzanine around four gas-powered electrical generators pumping out about 1.75 megawatts each. There will also be three 750-ton centrifugal water chillers, two 470-ton absorption water chillers, and one 125-ton air-cooled water chiller housed in the facility. The Central Plant will have a cogeneration capacity of 7.0 megawatts, which will provide the Airport with the ability to generate enough electricity to supply its facilities at a lower dollar rate than the local Southern California Edison (SCE) utility plant.
Airside Dock Access/North Trash Facility
The $2.5-million Airside Dock Access project consists of modifying the existing terminal gate in order to accommodate the new passenger boarding bridge that is being constructed. Barnhart will also oversee the construction of a new curtain wall, truck access ramp, and a large canopy that extends from the aircraft-parking apron into the existing loading docks, which are located below the existing concourse.
Barnhart will also manage the removal and new construction of the North Trash Facility (Facility). The existing facility is currently located underneath the Airport building, which is the location for the construction of the new Terminal C.
