Project report Erste Campus Vienna

A curvy challenge


The Erste Campus, the Erste Group’s new head office in Vienna, is a real eye-catcher. The curvy building complex in the Belvedere quarter is organically shaped with smooth edges – a sophisticated natural design. Roof gardens on different levels add to the natural building concept. Furthermore, the Erste Campus is extremely sustainable, which is also followed through when it comes to the interior.

However, there’s more to the complex than its looks. Its development was a real challenge for the architects Henke Schreieck, who were responsible for the planning and the construction. As an example, they had to install drainage channels with grates all around the curve-shaped building and the terraces. After all, regular channel bodies are straight, not curved, and so are the grates...

Sketch of the Erste Campus, the Erste Group’s new headquarters in Vienna. It was the architects Henke Schreieck’s goal to create a building with an organic, natural design.

A curve-shaped building poses a lot of problems – for example: what about drainage channels?

In order to meet this challenge, the project was put out for tender. Who can provide individual channel bodies and grates for our organically shaped building that also meet the claim of sustainability? These were the architects’ requirements. Three manufacturers applied – and BG was awarded the contract.

Their concept combined the excellent characteristics of the BG channel systems with our competent and comprehensive support.

Different channels made from our outstanding FILCOTEN® materials were installed, combining maximum eco-friendliness with excellent performance. This is particularly important with regard to compressive strength as well as temperature resistance and fire protection. In addition, our high-quality steel channels were also installed – their clever design offers a powerful solution for terrace and window areas.

The construction company in charge of the project started by mitering the channel bodies to prepare for the curve-shaped installation. Then the galvanized – and therefore rust-proof – grates were fitted. Simply cutting the grates to fit would damage the galvanizing, causing them to rust within the shortest time.

BG-Support at its best: 200 individually shaped and fully galvanized, tailor-made grates.

This is where BG’s support and engineering stepped in. Our technicians created individual layout plans for all grates and angles. These were used as a basis for technical drawings. In a number of steps, individually fitted grates were handcrafted and galvanized – for a total of 200 channel bodies. Thanks to a detailed plan, the installation was flawless. The result: Highly efficient channel bodies with corrosion-resistant, tailor-made grates.

Ready for the next challenge.

An extremely efficient drainage system perfectly adjusted to the building’s curved shape was created. Elegance and functionality in perfect harmony.

In the end, there is only one thing left to say: The BG-Group would like to thank the architects Henke Schreieck for their trust and for creating this fabulous complex. Whenever you face another challenge, you know where to find us.
