Harvey Milk Terminal 1 at SFO is a transformative, multi-year redevelopment of the original terminal, expanding to 25 gates and over 619,000 square feet.

Completed in three phases between 2019 and 2024, the concourse features natural light, expansive views, modern technologies, and a design that honors the legacy of Harvey Milk.

The terminal has also set a global benchmark in sustainability. It is the world’s first airport terminal to achieve LEED Platinum certification and the first to achieve full WELL Certification. Key features include a 1 MW rooftop solar array, water-efficient fixtures, and a construction process that diverted 95% of waste from landfills.

The new three-story, concrete-framed structure is supported by a pile foundation system, with below-grade spaces designed to interface with the groundwater. These spaces include a baggage and utility tunnel, elevator pits, and utility trenches.

Our team provided building enclosure consulting services from design through construction. Working closely with KYA Architects, we developed below-grade waterproofing drawings, conducted design peer reviews, and provided construction administration support—including RFI responses and submittal reviews. Our expertise contributed toward a durable, high-performance enclosure solutions for this landmark terminal.
