Abstract: An automated method of building construction utilizes a horizontal force to extrude a structural member formed from a plurality of elongate joists, upper panels, and lower panels. A framing machine includes an upper panel bay and feeder, a joist array and feeder, and a lower panel bay and feeder. The machine positions each joist and upper and lower panels into an installation position where fastening means forms the structural member, which is advanced out of the framing machine. Additional means for insulating the structural member, installing pipes and wires, and an exterior finish may also be provided.
