Building big and strong with precast concrete

The largest Bilhuset (Norwegian for a house of cars) in the whole of Scandinavia has risen to Sandnes, in the Southern Norway. This spectacular 29,000 square meters building was designed to meet the demands of the car selling industry. One of the goals was to reach high level of sustainability, where precast came to rescue.

Precast concrete was an optimal choice for the project, because of its high load-bearing capacity, robust surfaces and minimal maintenance requirements. The decision to use concrete as the main construction material enabled maximum utilization of the plot. Concrete elements and cast-in-situ were used for the ground floor, which required sturdy construction. The upper floors were built with lightweight constructions.

Because of the experience in manufacturing precast concrete elements and building car parks, Block Berge Bygg was chosen as the contractor for the project. They run one of Norway’s largest and most modern precast factories with high production capacity so the project could proceed as planned. Moreover, the company had expertise and experience for carrying out a project of that size.

The finished building portraits excellent design as the users’ needs of the building were taken into account throughout the project – from design to construction and beyond. The façades give the building a sophisticated look, suitable for the car market. Hence, using precast in a larger-scale construction serves the purpose, as the construction time is fast, high load-bearing capacity exists and the design of the building can be architecturally interesting.
