1. A method of modular construction comprising:
constructing a first concrete void form, the first concrete void form comprising a vertically extending first bent steel plate and a first steel frame having a top face, bottom face and four side faces, wherein a first side face of the four side faces and the top face of the first steel frame are covered with a first sheet of corrugated steel decking, the vertically extending first bent steel plate extending inwardly with respect to the first side face of the first concrete void form;
installing the first concrete void form at a construction site;
constructing a second concrete void form, the second concrete void form comprising a vertically extending second bent steel plate and a second steel frame having a top face, bottom face and four side faces, wherein a first side face of the four side faces and the top face of the second steel frame are covered with a second sheet of corrugated steel decking, the vertically extending second bent steel plate extending inwardly with respect to the first side face of the second concrete void form;
installing the second concrete void form at the construction site adjacent to the first side face of the first steel frame and aligning the first bent steel plate with the second bent steel plate to form a rectangular columnar gap, the first side face of the second steel frame being on a proximal side of the second concrete void form with respect to the first side face of the first steel frame;
providing a rebar mat between the first concrete void form and the second concrete void form such that the rebar mat is positioned immediately between the first sheet of corrugated steel decking on the first side face of the first steel frame and the second sheet of corrugated steel decking on the first side face of the second steel frame; and
pouring concrete between the first concrete void form and the second concrete void form to allow the concrete to fill a gap between the first sheet of corrugated steel decking and the second sheet of corrugated steel decking enveloping the rebar mat and forming a rectangular concrete column between the first concrete void form and the second concrete void form with a thickness greater than a thickness of a cast-in-place concrete wall formed by pouring concrete between the first concrete void form and the second concrete void form.
