HOK is collaborating with San Diego International Airport and Sundt Construction to design a new post-security connector building that will link the airport’s new Terminal 1 with the Terminal 2 East Headhouse, while also modernizing the adjacent curbside environment.
The new 40,000-sq.-ft. connector will replace the old Gates 20 and 21 walkways with new hold rooms and passenger boarding bridges, improving the passenger experience and enhancing operational flexibility. The project will also provide a post-security terminal connection for the first time, creating a more cohesive campus for travelers, airline staff and airport employees.
The connector will accommodate two narrow-body aircraft gates, curated artwork, concessions and restrooms. The design will celebrate San Diego and feature clear circulation paths and minimal columns to reduce congestion and create clear sightlines that guide travelers through the space.
On the curbside, HOK will improve the pedestrian experience through a plaza with hardscape elements, native plantings and signage, while preserving space for a future transit station. The connector will also include a curbside employee screening checkpoint and a convenience store accessible to both employees and travelers. An overhang along the building will protect pedestrians from the elements.
The project is targeting LEED v4 Gold certification. HOK is working with the airport on design strategies to improve the building’s energy efficiency and reduce heat gain.
The project builds on HOK’s longstanding design-build partnership with Sundt Construction at the San Diego International Airport. Together, the team has delivered five buildings at the airport, including the airport administration building, the facilities management department administration building, the facilities management department shops and warehouse building, the airline support building, and the airport fueling operations building.
“We are excited to partner with San Diego International Airport and Sundt Construction on this project, building on a strong history of successful collaboration,” said Hoang Nguyen, regional leader of Aviation + Transportation at HOK. “The design will establish a clear sense of place that reflects San Diego’s character while creating a calm, intuitive experience for travelers and employees alike.”
The Terminal 2 East Connector Building is scheduled to open in early 2029.
