Perforated metal sheet facade cladding
POWER & LIGHT BRIDGE
The zinc cladding's bumped and perforated surface interplays with light as a metaphor for the bridge’s functional purpose, transporting electricity. The architects at Helix were inspired by the physics of three-phase electrical power whose sine waves are represented by the emitting light through perforations on the cladding. The form of the bridge itself becomes a third sine wave, giving the skin undulations and shadows. The cladding was bumped and punched with small bumps of varying depths, representing a field of electrons through which electricity moves. This project won the 2009 AIA Craftsmanship Honor Award.
The exterior system uses the Inverted Seam™ techonology to smoothly connect the 375 unique panels with minimal visible horizontal and vertical joints between the panels. The scalloped metal shapes add further visual interest to the solution and the overall composition is further enhanced by it's illumination at night.
Zahner was responsible to the owner, the architect, and the general contractor to design, fabricate, and install an enclosure based upon the drawings, documents, and patterns provided by the architects.
