PHASE ONE - Pour Ring Beam Footing. Continuous reinforcing bars are embedded in the ring beam foundation. These rebar dowels securely connect the dome to its footing. Ring beam can be placed on a stem wall.
	PHASE TWO - Attach and inflate air form. air form airform is attached to the ring beam footing and inflated with dual inflator fans, each powered by an independent power source. An airlock entrance allows free access to the interior. The air form is a thin, tough membrane that becomes the dome's outer covering when construction is complete.
PHASE THREE - Apply polyurethane foam. Polyurethane foam is spray-applied from the interior to stiffen the air form and provide a secure surface to which reinforcement bar is affixed. The foam hardens and creates a superior insulating layer in the final structure. Note the hydraulic crane with a basket fixed to the end of the boom.
	PHASE FOUR - Reinforced Concrete. After the polyurethane foam is applied and allowed to harden, a framework of reinforcement bar is placed and attached to the interior surface of the foam. This will serve as a skeleton to which concrete is applied. Application of shotcrete to the reinforcement bar framework comprises the final step in construction of the dome. The rebar framework is embedded by the shotcrete, creating an extremely strong, fire resistant and energy efficient structure.
