An engineered 2''x8'' equivalent board is formed from a standard wood 2''x4'' board. The 2''x4'' board is bifurcated longitudinally to form opposed rails, and a longitudinal ½''x½'' groove is formed centrally of the cut face of each rail. Three ½'' thick OSB web pieces of predetermined length and width are cut and glued and stapled into the rail grooves. This produces a finished board dimensionally equivalent to a standard 2''x8'' board that has gaps between the rails that enable conventional plumbing pipes, electrical wiring, HVAC ducting, and insulation to pass laterally through the board when used as a stud.
