The Conco Companies are providing concrete services for a new 20-story high-rise office building in downtown San Francisco. The 469,000 square foot project includes 18 floors of office space, one lobby level, and a roof terrace along with a two-level subgrade parking structure. Additionally, as the office tower will incorporate the San Francisco Mining Exchange, a historic landmark, as its primary entrance, the project also includes the “Historic Renovation of San Francisco Mining Exchange Building.”

The client on the project is the Lincoln Property Company and Hathaway Dinwiddie is serving as the general contractor. The project was designed by the architectural firm of Heller Manus Architects and integrates the terra cotta façade and the columns of the landmark building with the office tower. The building is seeking LEED Platinum certification and will feature a number of environmentally advanced technologies.
