Custom Fastening Solution: A Milestone for the Visionary Children's Hospital Zurich
An innovative and forward-looking wood façade was developed for the new Zurich Children's Hospital building—a perfect combination of architectural aesthetics and functional technology.
In the dynamic world of construction, companies often face unique challenges that require innovative solutions. DF2 Fastening Technology AG was confronted with the demanding task of securing the wooden façade of a unique children's hospital in Zurich.
This project, realized by the renowned architectural firm Herzog & de Meuron, is a flagship architectural project considered a pioneer in medical care. In the course of this challenging construction task, Bossard was able to make a decisive contribution to the solution with our expertise in modern fastening technology and our comprehensive product portfolio.
The Challenge: Efficient Screwing for High Demands
The central challenge was to find a suitable solution for fastening the wooden façade to the new children's hospital. The high demands for efficiency and stability required a solution that enabled quick and precise assembly.
A classic assembly, where screws would have to be individually removed from the package, would have significantly slowed down the process and was therefore not an option. Belted screws offered the ideal solution here, as they allow for rational screwing and significantly speed up the assembly process. Together with DF2, we were able to develop an innovative screwing technology perfectly tailored to the project requirements.
The Solution: Efficiency Through Customized Screw Technology
With the extensive Spax product portfolio, we were able to find a screw that met both technical requirements and short-term availability. We offered the chosen solution – the BN 20948 façade screw – in the form of magazine long-strip screw, which greatly facilitated assembly.
The entire conversion process of the solution took about two years, during which the façade was prefabricated in the Davos plant and delivered to Zurich. The entire construction project spanned from 2018 to 2024.
Summary: Sustainable Success Thanks to Automation and Efficiency
The implementation of this innovative solution led to significant improvements in the construction process. By using magazine screws, significant time savings could be achieved, as they were immediately available and no longer needed to be sorted individually. This automation of the assembly system increased the efficiency of the entire assembly process during the pre-assembly of the outer cladding.
The customer, DF2 Fastening Technology AG, continues to benefit from this solution. Using magazine long-strip screws for the façade quickly paid off and has proven to be reliable and efficient for future projects as well.
