Moscone Center Expansion

Location: San Francisco, California
Anticipated Completion: 2018
Project Area: 800,000 ft2
Projected Cost: $551 million
Contractor: Webcor Construction, LP

The expanded convention center will keep San Francisco’s number one industry competitive, create thousands of new jobs, and enhance the neighborhood. Moscone Center currently generates more than 20 percent of the 16.9 million visitors to San Francisco, making it a main driver of business. As the city and the convention landscape continue to grow, this vital facility is expanding to meet future needs.

The above-grade additions and improvements will take place within the current building footprint, allowing for improvements to surrounding open spaces and the introduction of new retail opportunities. Pedestrian-friendly space will replace 25,000 square feet of surface parking and vehicular circulation, exit ways, and ramps. The project will add more than 8,000 square feet of new public open space, including a play area for younger children. Multiple outdoor terraces will provide dramatic city views and can be used for receptions and other events.

The $226 million expansion, which will include multiple dining venues and space dedicated for concerts showcasing A-list performers, marks the revival of a project that had been conceived a decade ago but was sidelined by the deep recession of 2008. It is expected to be completed by 2019.

As part of the expansion, the casino floor will grow to accommodate a total of 2,800 machines from the current 2,000, plus 38 more gaming tables.
