DBD Structures provided design/build construction and project management services to SFAI for the removal and replacement of 26,000 sf of encapsulated waterproofing membrane and concrete topping, 25,000 sf of selected clay tile and felt roofing and 5,000 sf of selected modified roofing.

The main campus of the San Francisco Art Institute (SFAI) consists primarily of two historical buildings. The oldest of the two buildings is a Mediterranean style, cast in place concrete, timber frame and clay tile roof structure which was completed in 1935. The second building is a modern, cubist style, cast in place concrete building with its roofs functioning as pedestrian plazas. This second building was completed in 1965.

The existing encapsulated system at the new building was replaced entirely with a Sarnafil single ply, welded system covered with high strength concrete pavers on pedestals. In the older building, the original clay tiles were carefully preserved and reused with new felt and copper flashings.

The Project had a highly accelerated schedule with a mandatory completion date based on commencing the work at the end of the spring semester and completing the Project prior to the beginning the fall semester at the school. Additionally, the Project was funded by a bond issue. Project costs in excess of the bond issue were not allowable.

DBD Structures? planning, design and construction of this Project was successfully completed within the required schedule and Project budget.
