535 Mission Tops Out in San Francisco

Swinerton Builders, owner Boston Properties, and architect HOK celebrated a major milestone this month with a topping-out ceremony at the 535 Mission Street high-rise. An industry tradition to mark the completion of the uppermost floor of a building, this topping out held special significance for all involved as the culmination of many years of planning and construction--with a lot of waiting in between.

Centrally located within blocks of San Francisco's Embarcadero waterfront, Yerba Buena Gardens, and the planned Transbay Transit Center (currently under construction), 535 Mission is a steel-framed structure that will house Class A offices and mixed-use retail space on its street level. The 535 Mission Street project is one of the first office towers in San Francisco to be pre-certified Gold through the LEED for Core & Shell program. Green features include storm water retention, natural day lighting, and an insulated glass curtain wall system that uses solar-reflective coating to conserve energy.

Swinerton has been involved with the project since 2007, originally contracted to build the 28-story skyscraper with a previous owner, and broke ground on the site in 2008. However, the project soon became a casualty of the economic recession, and construction was halted later that year. After several years of steady economic recovery in the Bay Area, Boston Properties purchased the project and retained Swinerton as general contractor.

The high-rise is slated for completion in October of 2014. Stay tuned for more updates as it reaches skyward.
