Demands are growing constantly in the manufacture of precast concrete elements: walls and floors are becoming more complex, delivery times shorter and changes ‘at the last minute' more frequent. Nevertheless, the customers of precast factories have a right to expect that quality and dimensional accuracy will still be maintained. In the Bürkle concrete works, laser projectors simplify many of the work processes involved in the manual placement of formwork elements and built-in components on the circulating pallets. They create ‘visual templates’ on the working surface that make fast, exact positioning of the parts possible and ensure the dimensional accuracy of the finished elements.
