Sponsored by the Architecture Foundation of Oregon, the Portland chapter of the American Institute of Architects, and Portland Spaces magazine, a reception this evening will include not only the scale model's unveiling, but a lecture at 7PM by the bridge's designer, architect Miguel Rosales of Boston-based Rosales + Partners.
But many of the costs and challenges have been unfairly exaggerated. The wave has been said to require high-performance steel produced by only one company in the United States, for example, which was a major strike against the concept. But according to Wenger, those details could easily have been overcome to make the wave competitive on price and with more common types of steel.
"It was stated by the client that only one source in the US could supply high performance steel with 4-inch plate thickness," Wenger explains. "High performance steel is available in Portland rolled up to approximately 3.5" thickness. The plate thickness could easily been overcome during the ongoing design phase, in order to comply with local supply and a wider choice of sources."
We're at a stage where all the bridge prototypes would need a lot of these details worked out. So to say the wave would cost vastly more is misleading.
