Prefabricated sanitary walls save time on large construction sites
The Berswordt Carree is currently the largest construction site and single project in new residential construction in Dortmund. 365 micro apartments for students and 222 high-quality rental flats are being built on the approximately 10,900 square metre site. In order to save time and avoid delays, industrially prefabricated TECEsystem sanitary walls were used in sections during the construction of this major project.
Dortmund's Kreuzviertel is popular and as a result, living space is in scarce supply. Many students from the nearby Technical College and the Dortmund Technical University seek temporary living accommodation here. The Berswordt Carree will make a significant contribution to meeting the demand for housing in the future. In addition to 45 to 125 square metres of rental flats, the new building includes 365 fully furnished micro apartments for students and professors with living space between 22 and 49 square metres.
Because the floor plans of the flats are individually designed, the bathrooms have been manufactured using conventional pre-wall technology. A total of 311 toilet and washstand modules have been used here. TECEflex plastic pipes were used for the entire potable water installation. The reliable TECEflex sleeve system works without O-rings, which makes it particularly safe to use and is also easy to process.
Unlike the flats, the micro apartments are all uniformly designed. For this reason, the Daume planning agency decided to equip this section with industrially prefabricated TECEsystem sanitary walls, whereas the bathrooms in the flats were built conventionally.
The dimensions of the sanitary walls are specially adapted to the bathrooms of the apartments and are prefabricated ex works for the potable water, heating, sewage and ventilation areas. Accompanying the project from the planning phase onwards, Anton Delorme from the TECE application engineering division worked alongside Daume as part of the TECEsystem package: “In a large project with many identical bathrooms, industrial prefabrication provides security in terms of time and costs. And the production quality is of a consistently high industrial standard. "
Close project support from TECE
The close cooperation between TECE and Daume started with the exploratory phase of the TECEsystem process, in which the individual requirements for the sanitary walls were specified. The current fire and noise protection standards as well as compliance with potable water hygiene were taken into account during this phase, which also increased planning certainty.
Once the pipe network plans and the production drawings of all sanitary walls for each bathroom had been drawn up, an exact delivery plan was created. This contains the various quantities requested for just-in-time delivery of the sanitary walls to the construction site. It was only after this detailed planning was completed that TECE began industrial production in the factory.
Just-in-time at the construction site
The prefabricated TECEsystem sanitary walls were delivered fully piped to the Berswordt Carree over a total of 25 deliveries. First, the installers performing the assembly were instructed on site by the TECE project support team. The prefabricated sanitary walls were then set up according to their labeling at their designated locations and attached to the building structure with sound-proofing elements and the pipelines connected. Step by step, the individual sections of the student apartments were installed quickly and on time.
Kim-Nils Lichtenberg, Daume site manager comments on TECEsystem: “We had previously experienced the benefits of industrial prefabrication in the construction process. A project like the micro apartments in Berswordt Carree is ideally suited for this. Thanks to the time saved building the bathroom, we were even able to make up for a delay incurred during the shell construction.”
