San Francisco, CA
An extraordinary effort by the City of San Francisco and the San Francisco Tourism Improvement District to expand existing convention space.
A three-phase expansion involving a limited portion of Moscone North and Moscone South, with approximately half of the work being done underground in order to better connect the two buildings and increase usable space.
Phase 1: Reconfigured truck routes, ramps, and entry points into the underground exhibit facilities while allowing for the continued operation of the convention center.
Phase 2: Reconfigured and expanded underground exhibit space by roughly 305,000 sf. Additionally, constructed new foundations for Phase 3 work.
Phase 3: Connecting the North and South facilities by creating a 240-foot, enclosed multispan concrete box-girder bridge at grade to maintain full-time elevated public access across Howard Street from Yerba Buena Gardens to the cultural facilities. Includes the creation of additional exhibit space below.
