The use of precast concrete elements in bridge construction has unquestionable advantages: As the elements are not made where the bridge is located, they can be built at the same time as other bridge parts are being constructed such as foundations, piers and abutments, thereby reducing the overall construction time. It is possible to use a larger area for precasting the elements or even various plants, which is a special advantage if there is only a small area available at the bridge site. The concretes used are stronger and have better characteristics. The fabrication tolerances, quality of the finish and quality control are better. Less struts, scaffoldings and forms are less required at the jobsite.
