Abstract:
1. A modular pre-cast concrete construction system comprising: a plurality of pre-cast concrete floor caissons, the plurality of caissons placed adjacent one another to define a cavity between each adjacent caisson, the upper lips of adjacent caissons define an upper width of the cavity and the lower lips of adjacent caissons define a lower width of the cavity, the lower width wider than the upper width, a plurality of concrete beams located in the cavities and spaces formed by adjacent caissons, the concrete beams defining an upper surface and a lower surface, the top surfaces of the caissons and the upper surfaces of the concrete beams forming a planar floor, a plurality of pre-cast concrete wall panels, rebar located in each of the caissons, wall panels, and concrete beams, rebar extending between and within adjacent concrete beams, concrete wall columns formed between adjacent wall panels, the wall panels and wall columns supporting the planar floor, and rebar extending between and within the adjacent wall columns and concrete beams.
