New construction with 172 residential units, Hohenschönhausen Berlin
Where others are still building, tenants are already living here
The demand for living space in Berlin is enormous - and space is limited. A new construction is under way in Hohenschönhausen with 172 residential units of a varying sizes. Varying apartment and bathroom floor plans make such building sites complex. To ensure a speedy construction workflow, individually designed and industrially prefabricated registers and wall modules were implemented in the bathrooms in every apartment. The installation times of the sanitary, heating and ventilation pipes are thus
drastically reduced; the property can be let on time.
On the 8,100 m² large plot in the Berlin neighbourhood of Hohenschönhausen, a horse-shoe shape residential complex has been under construction since May 2015, comprising a coherent building structure with a total of 7 blocks and around 11,500 m2 of living space. The different apartment types, ranging from one-and-a-half to four bedroom apartments, offer room for different life plans and budgets. In addition, the apartments located on the ground floor are accessible with no barriers. The apartments should be ready to move into at the end of the year. It's an ambitious target: For the general contractor Ten Brinke, a specialist in the construction of turnkey ready residential, industrial and commercial buildings, one of the most effective measures for optimising the construction workflow was the implementation of industrially prefabricated pre-wall registers.
Industrial prefabrications not only guarantees a high quality standard. The crucial point is that costs are fixed from the start and transparent – for the trade enterprise and the builders. This provides all of the participants with additional planning security. Julian Rüsen, the responsible project manager from Ten Brinke, is satisfied: "This isn't the first project where we've used TECEsystem registers. Compared with conventionally constructed pre-walls, we save a good 50 % on installation time thanks to the prefabrication." The registers were individually designed for the four different bathroom floor plans, manufactured in the TECE factory and delivered to the construction in 14 part deliveries ready for connection.
Just-in-time delivery of the registers
Each just-in-time delivery supplies registers for half a block. This is synchronised precisely: The service package for TECEsystem also contains a model register for the different bathroom types. These models are assembled as a test to ensure that everything fits. The big advantage for the plumbers from the contracted TGS GmbH: By installing the models, the assembly time and the working capacity required for the rest of the construction process can be planned precisely. Assembly in the structural body and connection of the standpipes and down pipe took up approx. 1.5 weeks. The walls made of sturdy supporting frames contain the complete sanitary technology as well as all of the pipes for drinking water and wastewater, heating and ventilation. Rather than numerous individual products, only a single finished unit is installed on the construction site. TECEsystem also meets the requirements for fire protection, sound insulation and thermal insulation. All components are perfectly coordinated and assembled in compliance with standards. The registers contain washstand and toilet modules with the TECE universal cistern.
Service on site at the construction site
Ralf Thowesten and Michael Armeloh from TECE in-house technical support were responsible for the problem-free operation on site. Alongside consulting in the run-up, they coordinated the coordination workflows and established the demand for products: "With a project of this size every delay in the construction process represents a financial risk for the building clients. We minimise this risk thanks to the quick lead time for industrial prefabrication and the subsequent just-in-time delivery." The construction of the sanitary systems on Gärtnerstraße went perfectly according to plan. The fitters assembled most of the registers immediately following delivery.
If the construction or the capacity didn't allow for immediate assembly, the registers were stored in the TECE container supplied with the first delivery to secure them against theft. The apartments located on the ground floor are all accessible with no barriers. In order to design the shower area free of barriers too, the TECEdrainline shower channel was used here. Thanks to the channel and the tiled floor we were able to do away with partition walls, which gives a generously spacious feeling. Included in the TECEdrainline delivery package is the Seal System sealing tape, which guarantees a permanently sealed connection between the shower channel and the composite seal that has also been tested with a range of different slurry seals. The future tenant in the building complex's four bedroom apartments will be spoiled with two bathrooms: one with a bathtub, the other with a shower. As the bathrooms adjoin each other, the sanitary register also serves as a partition wall here. Thanks to the integrated sound and thermal insulation, the resident won't notice a thing here.
