Precast concrete offers considerable scope for improving structural efficiency. Longer spans and shallower construction depths can be obtained by using prestressed concrete for beams and floors. For industrial and commercial halls, roof spans can be made up to 50 m. For parking garages, precast concrete enables occupiers to put more cars on the same space, because of the large span possibilities and more slender column sections. In office buildings, the trend is to construct large open spaces, to be filled in with partitions. It offers not only flexibility in the building but extends its lifetime, because of the easier adaptability. In this way, the building retains its commercial value over a longer period.
Precast prestressed hollow core floors offer maximum efficiency to the user. Due to the slenderness of the products and long span capacities, they create maximum exploitation capacity to the available building space.
