The Naval Regional Medical Center in Bremerton, Washington is an architectural tribute to the region's native Indian heritage. Some 52 precast concrete panels which decorate the elevator towers and visitor entrance of the hospital are sculptured in bas-relief forms which recall and venerate the Haida, an Indian tribe of the Pacific Northwest. The side walls of both elevator towers are adorned with totemic symbols of the tribe. On the front wall of each tower at the top is the symbol of the dragonfly, followed by six stylized reproductions of Haida storage boxes.
The authentic Haida Indian designs, adapted to the size and shape of the panels, were formed from reverse images or "negatives." Polystyrene sheets, 2 « inches thick, were cut into the particular shapes required and then anchored to the form panels. Steel reinforcement was installed in the forms, and the concrete was placed. After the forms were stripped, the remaining polystyrene embedded in the concrete was sandblasted away, and the sculptured relief was left behind. While in this case the panels were precast off-site, this procedure can also be used to form sculptured reliefs in concrete precast on site and concrete which is cast in place.
