Abstract
Abstract A method for constructing a building from a plurality of building elements comprising elongated column members with spaced rectangular notches cut therein, elongated spandrel members having spaced notched portions for interlocking with the notches on the column members and having a horizontal support surface for mounting and supporting floor members thereon. The columns and spandrel members interlock to form a rigid multi-story structure which enables the building to be constructed in sections.
