The San Francisco International Airport (SFO) Terminal 1 Boarding Area B Redevelopment (BAB) was a 619,150 SF six year design-build project. The upgraded Terminal 1 features new secure connectors linking Boarding Area A through Boarding Area D, and a customs secure connector between Boarding Area B and the International Terminal. The airfield layout was reconfigured to allow for more flexibility and greater international flight capacity, serving up to 25 gates for both domestic and international travelers. BAB offers a galleria-type retail experience at the entrance to the path through the building, as well as unique artwork by local artists. It includes open gate lounges, dining halls, museums, and a children’s play area integrated into a central lounge. A mezzanine level houses airline clubs and an international connections corridor.
