Masonry and metal buildings dominate the industrial/ commercial construction business in most areas. Tilt-up has been the concrete industry's alternative to metal/ masonry buildings but its successful use to date has been confined to parts of California, Texas and several other scattered locales. Although it offers the potential of a superior structure at reduced cost, tilt-up construction suffers form a shortage of contractors with sufficient experience. In actual fact, a good tilt-up system can expand a concrete contractor's market considerably, as evidenced by the success story of Miller-Valentine Corporation of Dayton, Ohio. The first step was to develop efficient construction methods. Applying techniques form the company's paving experience, Gerry Miller, confounder of Miller-Valentine, discovered that it is feasible to cast a continuous wall section a hundred feet or more in length face down on the lower slab, a method similar to casting a strip of pavement. The continuous-slab approach minimizes the amount of edge forming required and speeds the placement of reinforcing steel. The stirkeoff is accomplished by a paving machine or large vibrator screed- preceded by one laborer operating an internal vibrator and followed by one concrete finisher working a bull float. The savings in labor costs are obvious. A frequent misconception of many architects, engineers and owners is that a tilt-up building cannot be efficiently insulated. Miller-Valentine Corporation has developed several methods of insulating both the walls and roofs of their buildings, producing a U factor of .10 for a typical building. However, lower U values are also possible at costs equal to or less than those for metal buildings.
