Abstract: A multi-level precast composite concrete framing system includes a plurality of sets of precast composite concrete columns, with each set forming the vertical supports for the framing system between levels. The columns of the different sets are vertically aligned. The framing system includes at least one set of plurality of precast composite concrete beams forming the horizontal supports for one level. Each concrete beam includes at least one tie rod opening extending vertically through each beam at a location of each concrete column Each concrete beam further includes an access opening, which may be grouted after installation, providing access to each tie rod opening during installation. The framing system includes a plurality of tie rods each having a sleeve and opposed threaded pin ends threadingly received within each concrete column, wherein each column includes tie rods extending through the tie rod openings of at least two separate and adjacent beams.

Abstract: A method of constructing a shallow pier foundation building that includes a) placing a plurality of insulating pier forms along a perimeter of the building; b) placing a plurality of insulating concrete forms between the insulating piers to form a continuous insulating surface to the surrounding soil and a continuous forming surface to provide a slab form; c) placing a concrete composition in the insulating piers and insulating concrete forms and allowing the concrete composition to cure and harden; and d) placing a concrete slab composition in the slab form and allowing the concrete composition to cure and harden.
