BKF Engineers provided civil engineering services for the residential conversion of San Francisco’s historic Chronicle Building at 690 Market Street. The project transformed the former commercial structure into modern urban housing while preserving its architectural presence in the city’s core. BKF’s work included designing new storm drain, sanitary sewer, and water connections to support the building’s updated residential use, as well as implementing public frontage improvements that enhanced pedestrian access and complemented the surrounding streetscape. These upgrades helped integrate the renovated building seamlessly into the neighborhood, supporting its new function as a vibrant residential landmark.
