SGH designed the supporting structure for two primary features of the plaza.
Alaskan yellow cedar benches. To communicate the customized geometry of the internal, galvanized steel structure, SGH created a three-dimensional model. We developed sample shop drawings from this model to present the simple detailing of different, but similar, connections allowing for accurate and cost-effective pricing of the benches.
Precast concrete components. SGH designed lighted, wayfinding structures with internal hinges and faceted bench/bikerack/end-wall structures with integrated stainless steel rails. We designed the end walls to resist the impact of rolling trucks that could be parked on the plaza.
SGH collaborated with Stoss Landscape Urbanism, the lead design firm, and Höweler+Yoon, the media architect, to design the complex site with the following features:
Corian benches and pylons. SGH tested materials in our laboratory and performed finite element analyses to evaluate Corian benches and detail a digitally fabricated, aluminum plate support structure to accommodate thermal expansion and contraction of the Corian. We also designed Corian media pylons with integrated lighting and base benches.
Planting containers. We designed delicate steel framework to contain bamboo plantings supported on reinforced concrete foundations spanning over existing buried infrastructure, including a 48 in. wide gas pipe.
Tent attachments. SGH designed precast concrete pavers with hidden attachment points for tent structures of varying sizes used during events.
