ABT's ultra-slim hybrid staircase wins Dutch Concrete Award 2017

The ultra-slim hybrid staircase in ABT's head office in Velp has won the Dutch Concrete Award 2017 (Betonprijs 2017) in the category of concrete technology.

From the 83 submissions, including 25 projects / innovations in the concrete technology category, the 3D bicycle bridge in Gemert and the unique use of thin concrete slabs at the Zeelsterbrug in Eindhoven were also nominated. ABT is not only glass constructor and concrete consultant in this project, but also the client. Together with JHK Architecten, Si-X glas, Romein beton and Cornelissen, they pushed their limits.

“The need for beauty grows in confusing times. Beauty gives comfort. If concrete technology can be used for this, it serves an unexpected social interest. This ultra-thin staircase is beautiful. The combination with the glass balustrade in the structure is a true novelty”, according to the jury.

Way beyond the everyday limits
This graceful staircase goes way beyond everyday limits, both in the production techniques and in the calculations. The revolutionary design is a demonstration of the possibilities when UHPC and glass are combined: UHPC has proved to be a material that is versatile in its applications, even in thin slabs, and it needs virtually zero maintenance. Glass provides inspiration as a load-bearing structural material that can now even be bonded at its ends to all kinds of other materials, such as UHPC.

Honorable mention
There was one particular project for which the jury had special attention. Although the amount of concrete used was not enough to qualify for an award, the jury felt that the project deserved to be mentioned. It’s the project that has been submitted under the title: Dafne Schippersbrug. The Dafne Schippersbrug is a unique project, especially in the social field. The Dafne Schippersbrug is a key project that is part of the new bicycle route, which connects the old city center of Utrecht with the new extension Leidsche Rijn. What’s so special about this project and – in particular – the node at the bridge? It’s the focus on urban planning: the route solves the height difference between road and bridge with an elegant curl. The elegant shape of the bike path encloses the public space with park and basketball court and automatically embraces the new Montessori school at the Victor Hugoplantsoen. You can not wish for a better invitation to go to school by bike. The jury has rightly decided to give this project an Honorable Mention.

Concrete Award
The Dutch Concrete Award 2017 is an initiative of the Betonvereniging (Concrete Association) and is supported by the Cement & Beton Centrum (Cement & Concrete Centre), the BFBN, Rijkswaterstaat (Department of Waterways and Public Works), the ministerie van Infrastructuur en Milieu (Ministry of Infrastructure and Environment) and Platform Betononderhoud (Platform Concrete Maintenance).
