Lippestraße in Hamm: Digital construction from the first draft

Construction with digital support is faster, saves costs and is less error prone. The construction of a housing development in the east of Hamm, Germany, is the latest example of this: Thanks to Xella's own blue.sprint planning service and the use of mixed reality technology, Xella is once again working with beta Eigenheim on a digital construction site.

Relaxed living by the water - and on the edge of the Ruhr region in Germany: In the eastern part of the city of Hamm, Xella's long-standing customer beta Eigenheim is working on a construction development project for 21 semi-detached houses and four apartment buildings. Xella has proven itself to be an ideal partner for the large construction site on Lippestraße, not only with the reliable delivery of 3,000 cubic meters of Ytong and Silka. After projects such as the Kronprinzenviertel in Dortmund, which was also commissioned by beta Eigenheim, the construction company is also relying on comprehensive support from Xella's digital repertoire for the Lippestraße housing development.

Why digital construction saves so much time

The very first offers and drafts were exchanged with beta Eigenheim via the Xella planning service blue.sprint. Later in the construction process, the tool was used to precisely coordinate the production of components with the construction process, so that all parts were delivered to the construction site on time.

Thanks to planning based on BIM (Building Information Modeling) methods, networked and digital construction, Xella can precisely calculate both the material and the personnel on the construction site, which guarantees the customer beta Eigenheim an always up-to-date and precise overview of the costs on the project.

Thanks to Xella's consulting services, the houses were planned and optimized in advance in such a way that hardly any cutting work is required between production and installation of the materials - for example, through optimized and gridded placement of doors and windows. The components can be installed so quickly that a complete floor, including windows, can be built into the shell in one day. All in all, planning in the digital twin saved twelve days and 190 man-hours on the construction site right from the start.

Ideal testing environment for HoloLens

Xella also tested the HoloLens in this digital environment. The glasses create an image that mixes the real construction site with virtually planned components. This makes it easier to plan the next steps on the construction site - with success: "The tests on this construction project showed that, thanks to the digital twin, construction went according to plan," says Andreas Radischewski, Transformation Manager at Xella. The apartments are expected to be ready for occupancy by the beginning of 2024 at the latest.
