The bandshell was constructed and assembled by our team in a warehouse in San Francisco's Potrero Flats. It was then disassembled, loaded onto a 50' flatbed truck, and brought to the Panhandle Park, where it was reassembled on site (see the project construction photo gallery).

The bandshell is comprised of four main parts: a structural skeleton, the skin, the stage, and a back wall. The structural integrity has been approved by a certified structural engineer, and received a City of San Francisco Building Permit prior to construction. Here are some of the technical details about how this structure is built.

Structural Skeleton

• Four cross-braced 4”x4” HSS structural steel arches, 16'8" high at their apex
• Arches are bolted into trapezoidal foundation of 7 I-Beams, shimmed level with lumber
• Rear-most I-Beam section acts as "kickstand" uplift and lateral shift protection

Skin

• 65 mid-size sedan car hoods, bolted to each other, and to structural skeleton arches
• Car hoods undersides are painted with custom-color grey primer, outsides treated with anti-graffiti acrylic coating
• Arches covered by computer circuit boards attached to reclaimed plywood, painted with "International Orange" latext paint (the color of the Golden Gate Bridge)

Stage

• 45'x20'x18" raised stage
• 60 hollowed-out French doors, inlaid with reclaimed 2"x6" and 2"x4" lumber, atop reclaimed lumber frame system
• Includes 30'-long ADA compliant ramp
• Stage is stained and waterproofed
• Plinth (stagefront) is reclaimed plywood decorated with reclaimed streetlight lenses and hand-drawn stencil design

Back Wall

• 3,000 16.9oz. (500ml) plastic water bottles glued with clear silicone caulk, reinforced by turnbuckled steel cable braces
• Wall divided into 3 separate panels, and nestled underneath rear arch
