You won't find your traditional horizontal and vertical construction with this project, nearly every elevation incorporates sloping compound geometry. The unique shape of this structure meant that traditional means-and-methods of layout and measuring were out the window. Mission Glass relied solely on 3D layout points using latitude, longitude and elevation markers to pre-fabricate and install the sloped glazing system. This required tremendous coordination up-front to ensure all of the geometry fit together seamlessly at each elevation and was carefully integrated with the surrounding structure and metal wall panel system. Beyond the unique sight-lines, nearly the entire project is wrapped with glass guardrails, allowing the public to flow through the complete footprint of the structure. While challenging, this project highlights the strength that 3D modeling and construction has in all of Mission Glass' processes. The Denny Substation is now a key feature and landmark in the City of Seattle and redefines the limits of what a power substation can be.
