Abstract: A composite automated building construction system, with automated alignment of various truss and wall sections, includes a wall section having frame, an expanded wallboard, and a concrete layer. The wallboard includes an outer portion and inset portion wherein the wallboard is attached to the frame with the outer portion covering an exterior side of the frame and the inset portion is disposed within the frame. The wallboard thus provides exterior and interior insulation for the system. The concrete layer is sprayed on to the outer portion of said wallboard, forming a strong durable composite construction system. A building is constructed with these wall sections by way of a base form template delimiting the boundary of the building. The base forms are installed and then a concrete foundation slab is poured over the base forms. Pre-installed bolts extend above the concrete foundation to providing pre-determined mounting points for the frames for the wall sections.
