2016's Harry H. Edwards Industry Advancement Award winner proves that precast concrete enables the most innovative architectural designs while providing a highly energy-efficient and durable envelope. One of the most prominent features of the building is the white precast concrete façade, which dips dramatically away from the walkway along the eastern edge, then tips back out again, much like the buildings in a Dr. Seuss story. “One of the key design challenges was to create that curved façade from precast panels,” says David Bosch, engineering team leader for High Concrete Group. The curved load-bearing design was achieved by assembling flat, traditional precast concrete panels to form a complex faceted geometry. An interlocking structural system was embedded within the panels to eliminate the need for traditional precast concrete spandrel panels. “The resulting façade creates an aesthetic versatility that is unique to the project,” Bosch says.
