One Rincon Hill, San Francisco
Client: Solomon Cordwell Buenz (SCB)
Containing two slender towers rising 741 feet with a “footprint” of only 9,800-square feet, One Rincon Hill is the first building in the US to have a liquid tuned mass damper. It is designed to reduce sway from earthquakes and powerful Pacific winds. As the wind moves the building one way, water in two tanks atop the building rolls in the opposite direction, reducing the building’s motion.
Together, the towers have a total of 731,000-square feet The West Tower is 55 stories high and contains 368 units, and the East Tower is 45 stories high and contains 327 condominiums. The podium hosts 14 town homes.
Common area features include a swimming pool, sun deck, health club, hospitality room, and a parking garage hosting 455 spaces. The interior of the building is built around a concrete and reinforced steel core anchored in a twelve-foot-thick foundation.
