Basically, the cost of concrete, steel, equipment, wages, etc., are the same for all contractors. The difference between profit and loss lies in construction procedures. One of the few items under a contractor's direct control is his method of forming concrete. The choice of the forms, themselves, may be of little significance when compared to the choice of the ties. A comparison between low-capacity and high-capacity ties indicates that the higher cost for the structural requirements of a form to be used with high-capacity ties may result in a low breakeven point in direct costs and, more importantly, may have a decided effect upon job progress.
