Pour a simple floating concrete perimeter with a channel to receive the arches. (If you will be using a flat foundation, base connectors are recommended.) 

Assemble arches on the ground. The precision-made arch panels bolt together quickly and easily with only one-size bolt and fastener. Caulking and neoprene washers ensure a weather-tight seal.

Slide arches into foundation channels and raise upright. If only assembling and erecting half-arches, use basic supports or scaffolding to hold them in place and speed-up erection process.

Arches are raised and progressively joined together. Precision engineering ensures a snug fit. Half-arches can be lapped and bolted together to make a full arch.

Seal the arches at their base with concrete for foundations with channels or bolt them to the optional base connectors (for flat foundations)

Any number of accessories or components can now be added to finish off your building: endwalls, insulation, man or garage doors, windows, ventilators, and translucent fiberglass panels (skylights).
