Frequent Travelers Unite: Making room for a branded hotel in downtown SFO

The Virgin Hotel in San Francisco – Sir Richard Branson’s second U.S. branded boutique hotel location – is a newly constructed 12-story, 78,000-sf hotel located near Yerba Buena Gardens, Moscone Center, and a future municipal subway station. The 196-key boutique hotel includes two penthouse suites, a rooftop bar, fitness center, and 7,000-sf of flexible meeting rooms/event space. There is one basement level for mechanical equipment. 

DCI Engineers was the structural engineer of record for the demolition of the previous structure, shoring for future basement expansion, and the newly concrete framed hotel. Virgin Hotel is situated on a small building footprint given the large number of building services, so much of the programming was placed in the basement.

Project Highlights

  • Virgin Hotel is the first PT concrete high-rise in San Francisco to feature a 6 ½” thick floor system, compared to the industry standard of 8” thick slab depths. The thinner slabs reduced the seismic mass, as well as the shear wall and foundation demands.
  • When the project team could not acquire easements from neighboring properties, the team cantilevered the shoring to stay fully within the property lines.
  • The building is in close proximity to a future MUNI tunnel currently under construction. DCI Engineers supported the mat foundation with cast-in-place auger piles to transmit building loads below the future adjacent tunnel.
