The project consists of a new 25,000sf sanctuary and links to two existing church buildings. The main roof structure over the octagonal nave is a combination of glu-lam wood and steel framing. Project requirements and aesthetics, required that three sides of the octagon be truncated. This changed a simple, symmetrical system, into a complex system with asymmetrical loading. The solution to this complex structure was a combination of a dome and folded plate design. There is a center compression ring at the top, and a partial tension ring at the perimeter base of the roof. Framing between the compression and tension rings consists of radial glu-lam girders, purlins, and tongue and groove roof deck.
