Precast elements have been used for decades in the building industry. Main reasons for this are reduction in price, reduction in erection time, and increase of the quality as production in factories often reduce the possibility of faults.

Since the beginning of the 70's, we have in Denmark made several attempts to change from large panel buildings into systems which allow much more flexibility in the use of the building including changes during the lifetime of the building Column/beam/slab building systems have been introduced, but the flexibility is still limited.

Column/slab building systems are preferred, but due to transportation and lift capacities on the sites, the size of the slab elements is limited.

A building system with great distance between columns, reasonable sizes of slab elements and great possibly for the architect to from the facades including use of balconies and chances in facade lines, would be a step forward for the building industry.

The Building Department of the Education Ministry has initiated such a development, and a very simple building system will be used for the next building complex at Aalborg University.

The partners who did the development for the Building Department, are Carl Bro Group, Dall & Lindhardtsen and Aalborg University.
