ABSTRACT A concrete building formed of precast cored wall slabs (12), floor slabs (14) and precast cored bond beams (36) The precast cored members (12, 14, 36) are manufactured at a remote factory location and transported to the building side where the wall slabs (12) are erected side by side and the bond beams (36) placed along the tops of the wall slabs (12) with a downwardly opening groove in the lower face of the bond beams (36) seating the upper edges of the wall slabs (12) and the cores (44) in the bond beams (36) vertically aligned with the cores (16) in the wall slabs (12). The ends of the floor slabs (14) are then placed on the bond beams (36) in a position spaced from the inner face of an outer flange portion (50) of the bond beams (36) and clear of the aligned cores (16,44) to form an upwardly opening trough (52). Vertical reinforcing rods (46) are positioned in the vertically aligned cores (16,44) of the bond beams 538) and wall slabs (12), a horizontal reinforcing rod (54) is placed in the upwardly opening trough (52), auxiliary rods (66) are placed in the spaces (68) between the adjacent floor slabs (14) and extend into the trough (52), and cement is poured into the aligned cores (16,44), the trough (52), and the floor slab spaces (68) to embed the various rods (46,54,66) in the poured cement and form a rigid unitary building structure. Insulating panels (18) are secured to at least certain of the wall slabs (12) at the remote factory location so that the wall slabs (12) may be placed side by side with the insulating panels (18) on the exterior of the slabs (12) providing a preformed exterior insulation layer.
