A construction assembly includes two frame members. A segment of one frame member contacts a surface of a contour of a first column. A segment of the other frame member contacts a surface of a contour of a second column. The surface of the contour of the second column aligns with the surface of the contour of the first column. A connector beam has a planar surface substantially perpendicular to a base surface from which the first and second columns extend. A first end portion of the connector beam couples to one frame member, and a second end portion of the connector beam couples to the other frame member. When coupled to the frame members, the connector beam substantially aligns with, and extends laterally between, the frame members. The connector beam receives blocks such that the planar surface is at a direct abutment with a planar surface of each block.
