Located on the San Francisco Embarcadero Promenade between Pier 30-32 and Pier 38, and replacing Piers 34 and 36, the Brannan Street Wharf will be a large new public park jetting out over the water.
Located in the center of the emerging South Beach waterfront, it will provide a lawn area, a waterside walkway with seating, a shade structure and a small-craft floating dock for kayaks and recreational water vessels. The wharf will be mostly flat, with the lawn contained in a raised planter about 18 inches in height and surrounded by a seat wall. The open site orients the wharf toward both the Bay and the adjacent neighborhood. To memorialize San Francisco’s waterfront history, the Brannan Street Wharf will display a restored version of Pier 36’s original signage. Also, interpretive displays will be added to highlight the location’s maritime and neighborhood cultural history.
The park will be wedge-shaped—40 feet wide at the short end and 140 feet wide on the long end, measuring 830 feet in length. The wharf is supported by 146 octagonal precast piles and 116 steel pipe piles. A 16-inch thick deck containing over 3,300 cubic yards of reinforced concrete will make up the structural deck. Additionally 2,700 tons of large rip rap will be put in place to protect the shoreline.
To date, Dutra Construction has driven the majority of the octagonal concrete piles (up to 99 feet long) and steel pipe piles (up to 105 feet long). The remaining piles will be driven by the middle of November. The false work and formwork has been installed for the first two pours (half the deck) and the rebar installation is ongoing. After the first of the year, Dutra will begin all of the topside work to turn the concrete deck into a park and tie the existing sidewalk into the new wharf. The majority of this topside work will be done by Bauman Landscape, a local business in San Francisco.
San Francisco has been one of the world leaders in implementing sustainable building practices, and this project has adhered to those goals. Among many other things, vibratory hammers were used to minimize impact to the Bay floor and marine animals while cushion blocks and jetting were used for driving the concrete piles. In addition, special truck haul routes were established to minimize intrusion and emissions of delivery trucks in residential areas.
The new 57,000-square-foot waterfront park will be 830 feet in length with a width of 40 and 140 feet on opposing ends.
