Two curved walls of different radii had to be formed in the construction of St. Thomas More Worship Center in Englewood, Colorado. The outside wall of the round sanctuary was made up of two semi-circles, on 60 feet in radius and one 75 feet in radius. Normally, a separate set of forms would have been built for each radius. To cut costs and make the bid more competitive the contractor had his form supplier custom design a set of adjustable panels which could form both radii. Adjustable curved walers made it possible to create the two different wall radii with the same forms. Two threaded adjustment devices on each waler were either tightened or loosened to decrease or increase the radius of the curve.
