The Challenge
Located 265 kilometers (165 miles) south of the Arctic Circle, Dawson is subject to considerable snow loads. The courthouse required a snow retention system that could restrain snow loads of 50.5 pounds per square foot—one that would not penetrate the roof and maintain a pleasing aesthetic.
The roofline geometry is uniquely complex, featuring two different slopes, dormers and a cupola with wide seam spacing, requiring two rows of snow retention. Given this was a government building and a historical site, there were more stringent requirements for the roof project, including a higher level of engineering, documentation and professionally engineered stamped drawings.
