Coordinating construction within an active terminal at San Francisco International, which sees 47 million passengers annually, made logistics particularly demanding on this $12.25-million project.
The 11,000-sq-ft build-out relocated Alaska Airlines’ lounge from Terminal 2 to Harvey Milk Terminal 1, expanded amenities and upgraded finishes. Delivered on time and within budget in July 2024, the lounge features include a bespoke Fireclay tile mural in Alaska Airlines’ color palette and a custom 40-ft laser-cut acoustic wall of the Golden Gate Bridge that serves both a symbolic and acoustic function. Custom metal twists combined with integrated millwork and acoustical ceiling systems deliver a layered approach to sound mitigation.

To accelerate the schedule, the contractor leaned on lessons learned from previous SFO projects, particularly when it came to minimizing airport-specific protocols. Badging processes and operation requirements were coordinated months in advance, ensuring the on-time mobilization of trade partners to access the airfield and terminal. The team strategically integrated daily operations to meet noise and security requirements by phasing and limiting off-hour work while minimizing operational disruption to the airport and passengers. Strategically dividing submittal packages by zone and scope allowed construction activities to proceed on some areas while design refinements were finalized on others in parallel. For this portion of work, virtual design and construction tools were critical, such as a preconstruction heat map that identified floor low spots and benchmark variances. This ensured constructibility alignment and helped the team sequence framing and finish details more accurately ahead of materials arriving on site.
The LEED Gold certified space features a biophilic design approach, incorporating natural wood, daylight and plantings. Sustainability strategies included diverting 80% of construction and demolition waste—despite the logistical challenges of removing debris through an active airfield—and cutting indoor water use by 35.74% with high-efficiency low-flow fixtures and water-saving design strategies.
