Abstract: A building system with modular precast concrete components uses bulb tee beams to span between walls that are distributed within the building footprint to open up the structure. Shallow corrugated slabs span between the bulb tee beams to form the floor deck. Optionally, double tee beams can be used at the periphery of the structure for longer spans.

Abstract: A reinforcing bracket has a planar central portion extending parallel to the reinforcing members with at least one central opening to receive a lifting anchor. Two V-shaped wings extend out of the plane of the central portion from the opposing ends of the central portion. Sets of aligned openings pass through these wings to receive reinforcing members.
Abstract: A mesh spacer has vertical members extending outward with an X-shaped cross-section and horizontal dimensions that allow insertion of the spacer into an opening in a lower layer of reinforcing mesh in a first orientation. Notches in the lateral edges of the vertical members engage the reinforcing strands of the lower layer of mesh in a second rotational orientation of the spacer. An upper layer of mesh can be placed on the top surfaces of the vertical members and secured with ties that pass through openings in the vertical members.
