San Diego International Airport Terminal 1 Expansion

under construction

The project involves the expansion of Terminal 1 at San Diego International Airport, including a new terminal structure with 30 gates, an expansive parking garage, and a comprehensive network of new access roads with nine new bridges, multiple retaining walls, and on-grade and elevated roadways. The project addresses seismic challenges due to its location near the Rose Canyon Fault Zone and on hydraulically filled reclaimed land, implementing deep foundations, ground improvement techniques, and site-specific seismic response analyses to mitigate earthquake risks.
