PLASTIEK KOEPEL Palace Hotel, Lost City 1992 Die koepel oor die rotonde van die Palace Hotel is met 56 liggewig dekoratiewe glasveselversterkte plastiek panele bedek. Die panele is op poliuretaanskuim vorms tot 'n minimum dikte van 6 mm gemaak. Hulle weeg 60 kg elk. Koperpoeier is in die buitenste laag geïmpregneer om dit na koper te laat lyk. Die koperpoeier is met suur ge-ets om die verouderingsproses daarvan te verhaas Die panele is langs die rande versterk en op gegalvaniseerde staal latte met dakboute bevestig. Die koppe van die boute is met hoëdigtheid poliëtileen doppe bedek wat die voorkoms gee van 'n klinknael. Voeë tussen panele is oopgelaat om toe te laat vir beweging. Die koepel onder die panele moes derhalwe waterdig wees. Dit is bereik met patente waterdigting op ‘n soliede houtplank basis met skeepslaaghout radiale ribbe. Die koepel is binne met gepleisterde gipsbord en kunsskilderwerk afgewerk. Argitek: Wimberly Allison Tong & Goo, California, USA.

The panels were made on polyurethane forms to a minimum thickness of 6 mm. They weigh 60 kg each. Copper powder was impregnated in the outer layer to resemble a copper finish. The powder was etched with acid to accelerate the ageing process. Panels are reinforced along the edges and fixed on galvanized steel battens with roof bolts. The bolt heads were covered with high-density polyethylene caps to resemble rivets. The top of the dome was covered with a decorative cap of the same material. Joints between panels were left open to allow for movement. This required a waterproof finish below the panels, achieved by means of patent waterproofing on a solid timber board base with marine plywood radial ribs. The interior of the dome is finished in plastered gypsum board and artistic painting. Architect: Wimberly Allison Tong & Goo, California, USA.
