Abstract: A method of assembling a two-sided wall on, through and around a preinstalled structural grid, the method including the assembly of planar wall units, each having an outer side and an inner side, the inner side opposing an inner side of at least one other planar wall unit on an opposite side of the structural grid. Interlocking features extend through a space in the structural grid and span from at least an inner side of one planar wall unit to the inner side of another planar wall unit on a same course level so as to support and gauge opposing planar wall units with respect to the structural grid. When installed in courses around the structural grid, the wall units and the interlocking elements create a continuous void between planar wall units to enable structural fill material to be poured therein filling the continuous void from the top of the wall to its base.

Abstract: A clear, permanent form, for steel reinforced concrete structures. Sections of the clear form, are to be factory extruded, from a clear polyvinyl chloride material, so as to make the assembly of the forms, the installation of the steel and utilities, and the inspections that are required, easier.

The clear form consists of two factory extruded profiles, that are totally different in shape. The sections that make up the form, can be modified, cut to any length or angle and assembled on site. It takes two sections, of one profile, to form both vertical sides of the form, and two sections, of the other profile, are horizontally inserted, between the vertical side sections, to create an elongated empty container. The assembled clear form is 7⅝ inches wide and 8 inches high, and is open on four sides.
