Interior view prior to pour. The arch of the roof is visible, as well as the framing for the side walls. Concrete is poured on the roof and walls at the same time, making each module a single structure, with no seams. Each module uses 50-60 yards of concrete.

The black cylinder in the right of the photo is the hydraulic piston that lifts and supports the roof form in place. The roof form is made up of fiberglass panels, with the walls formed by flat aluminum forms held together with pins.
