Boarding  Area G handles international flights for multiple airlines operating in a  common-use configuration — a concourse that cannot go quiet and cannot lose capacity. The existing passenger boarding bridges had reached the end of  their design lives, but replacing them meant working inside one of SFO's most operationally sensitive environments, where a single misstep in sequencing  could cascade into airline schedule disruptions and federal compliance issues.

The technical scope spans every layer of the airside infrastructure: new  pile foundations, Advanced Visual Docking Guidance Systems (A-VDGS) at all 12  gates, telecom and electrical upgrades, exterior apron concrete panel  replacement, and a full underground utility and above-grade fire line reroute. Construction is non-sequential by design — phasing moves between non-adjacent gates rather than progressing gate-to-gate — to preserve maximum scheduling flexibility for airline tenants. All work is performed 24/7 within an active Air Operations Area, requiring continuous coordination with SFO, airline tenants, TSA, CBP, and FAA.

Webcor is delivering the project as progressive design-build alongside architect Corgan and key partners AERO Systems Engineering and Burns &  McDonnell. Badging through CBP — a process that takes one to two months per person — is the project's top access risk. To keep design coordination and trade procurement moving without waiting for physical site access, the team implemented Matterport 3D scanning of the terminal, enabling full virtual site walks for unbadged team members. Webcor also issued early notices to proceed to select trade partners ahead of final award confirmation, accelerating onboarding and protecting the schedule from day one.

This is Webcor's 12th project at SFO since 2014, and the first at the airport to install AI-enabled PBBs that autonomously dock to aircraft — a technical milestone that positions Boarding Area G as a model for future gate  modernization across the terminal complex.
