Logistically challenging, the “One Kearny” project, completed in January 2009 and located at the heart of downtown San Francisco, is short on lay down area but long on opportunities to prove technical expertise. Situated at the corner of Market and Kearny streets in San Francisco's Financial District, One Kearny is a Class A redevelopment combining three buildings that represent three distinct architectural periods dating back to 1900.
DPR's project manager for the $30 million, 60,000-sq.-ft. new addition to the project. One Kearny includes the demolition of an existing three-story building, ground-up seismic construction of an 11-story high rise on one of the most logistically challenging sites in the city, the historical and seismic renovation of an existing 12-story building constructed in 1902, and the modernization of a building designed by famous architect Charles W. Moore. The three adjoining buildings—the new 60,000-sq.-ft. building, the historic 1902 64,000-sq.-ft. building and the Charles W. Moore “annex,” which was added to the 1902 Building in 1956—will become one, with a shared opening between the three different addresses, and offer boutique office space and retail space on the ground floor.
Demolition of the existing three-story building began in August 2007 and construction started on the new 11-story addition in November 2007. With zero lay down area and only 800 sq. ft. of parking lane to deliver materials, the project team has had to employ a tower crane, set 240 ft. above one of San Francisco's busiest intersections, to immediately pick up materials and place them into the building.
Along with the tight Market Street location, the construction team is challenged with maintaining the integrity of the two historic buildings, while constructing the attached contemporary steel-framed addition designed by San Francisco architect and structural engineer Charles Bloszies. The project also includes a complete state-of-the-art seismic renovation, ADA compliant upgrades throughout the development, and installation of the latest telecommunications and security systems. In addition, new elevators and a new, energy-efficient curtain wall, which must look exactly the same as the old curtain wall to maintain the structure's historical building status, will be installed for the annex project.
