Abstract: A process for fabricating a columnar assembly of spaced reinforcing bars comprising the steps of suspending a first plurality of reinforcing bars in parallel, spaced relationship; positioning a first constraining hoop in a plane generally perpendicular to said first plurality of reinforcing bars and in contact therewith; attaching said first plurality of reinforcing bars to said first constraining hoop; positioning a second plurality of reinforcing bars in spaced relationship to each other, parallel to said first plurality of reinforcing bars, and in contact with said first constraining hoop; and attaching said second plurality of reinforcing bars to said first constraining hoop. A variety of additional reinforcing bars and constraining hoops may be added in various ways to the basic unit.
