The design produced by Vernon L. Dunagin, AIA for the roof replacement at the art deco Seaholm Power Plant proved challenging. The building was constructed in 1950, and operated until 1989, supplying power for the City of Austin. Challenges involved working on a “brown field” site where hazardous materials were being removed on a daily basis. The roof had to be especially durable to hold up under a fireworks bombardment which was set off twice each year on the plant grounds. Falling shell casings had created significant problems with the previous roof. An aluminum clad membrane was selected and proved to be durable enough to prevent damage, but also more cost-effective than any other system available on the market.
