John Wayne Airport

Experiencing growth in its passenger service, John Wayne Airport in Orange County, California, began an expansion program that included additional terminal space, a new central utility plant (CUP), the replacement of an existing parking structure and the addition of a new parking structure. Turner & Townsend Heery provided commissioning consultancy services for the new central utility plant and the new Terminal C, as well as mechanical, electrical and plumbing systems design constructability reviews for the two parking structures.

Turner & Townsend Heery also performed commissioning consultancy services for the new central utility plant which provides electrical generation and is the main chilled/hot water plant at the airport. Chilled water is provided by a hot water absorption chiller plant, using the recovered heat from the seven-megawatt power plant. The facility provides all central plant utility requirements for both the new and existing terminals. The new parking structure accommodates up to 2,500 additional parking spaces on airport property, and the replacement of the southwest parking structure.

The new multi-level, 300,000 SF terminal project, located adjacent to the existing Terminal B, provided six additional bridged aircraft gates and two new, multi-gated commuter terminal halls. The new and existing terminals had HVAC, lighting, electrical, direct digital control (DDC) system, Customs & Border Patrol (CBP) and TSA security station check points, detention cells, interrogation areas, new elevators and travellators, as well as flight and the baggage claim information display systems in the commissioning scope of work. The project team also planned and managed the operational readiness exercises which verified the facility would meet the passenger needs and operational needs of the airport and airline services, prior to acceptance of the project. Access to all gates in both the new and existing terminals is provided through a single secure concourse.

The project received an “Exceptional Project” award in the Buildings - New/Renovation category at the Western Council of Construction Consumers, 2013 Owners’ Project Excellence Awards for Terminal C.
