Designed, fabricated and installed by Portland’s rhiza A+D (with support from PDC and Summit Group), this sculptural paean to the Port of Portland is composed of brushed aluminum and stainless steel. Part aeronautic wing, part voluminous cloud, “Cloud Cavu” is formed around the experience of arriving and departing by plane through Portland’s winter cloud-filled sky. Riding MAX to the airport one passes the sculpture with its allusion to takeoff and descent – touching down with a cluster of tilted stainless-steel rain-columns. The smooth metallic belly echoes the shape of a polished upturned wing or fish belly and an opening provides a glimpse of luminous blue beyond. The top and sides are matte, brushed, bolted patterns of turbulence, wind shear and laminar flow.
