  • More living space from the system

    More living space from the system

    The construction and real estate industry is under pressure. Construction costs are rising, there is a shortage of skilled workers, the population continues to grow and climate targets set clear limits for CO₂ emissions. Serial construction provides answers to these challenges.

    Thanks to industrial prefabrication and standardized processes, construction times are shortened, workflows are more predictable and projects are more economical. The construction site becomes an assembly site, with less noise, less impact on the neighborhood and higher quality workmanship.

    What serial construction is all about
    Serial construction sees the building as a product, not as a one-off prototype. A system is intensively developed, thought through and used in many projects. Elements are largely created in the factory and assembled on site. This allows for precise costs and continuous improvement based on experience. Classic problem areas such as connections, thermal and sound bridges can be specifically mitigated.

    From prefabricated buildings to the “Teslamoment
    Serial construction methods have a long history, from the early timber systems of the 1920s to the “Göhnerbauten” in Switzerland and prefabricated housing estates in the East. The efficiency was high, the design quality often not and the image still suffers today.

    The topic is currently experiencing a new wave. Hybrid systems combine room modules and 2D elements, offer more flexibility for different plots and regulations and are bringing architecture and urban planning back on board. Projects such as the student-oriented “Woodie” in Hamburg show that serial construction and architectural quality do not have to be mutually exclusive.

    Strengths: Time, costs, quality, climate
    Serial systems shorten construction times and increase cost certainty. Because components and details are standardized, budgets and deadlines can be set early and reliably.

    At the same time, industrial production opens up new scope for sustainability. Specifications for CO₂ reduction, material selection and energy efficiency can be consistently written into the system. Material passports and platforms are used to document installed components, making them visible as a resource for subsequent conversions or dismantling.

    Acceptance determines the future
    The big challenge is perception. In many people’s minds, serial construction stands for monotonous architecture and social problem districts. As long as current projects are only partially convincing in terms of design, this skepticism will persist.

    To be widely accepted, buildings need to deliver more than just efficiency. Good floor plans, a high quality of stay, differentiated outdoor spaces and careful integration into the urban space. Standardization should be seen as the basis on which diversity is created.

    Serial construction can become a central component of the building turnaround, faster, more plannable, more resource-efficient and circular. The technical prerequisites are in place, as are successful pilot projects.

    Whether the approach experiences its “Tesla moment” now depends on whether the industry and cities manage to combine industrial processes with high quality living and design and thus show that repetition does not mean uniformity, but can be the basis for sustainable, diverse neighborhoods.

  • The symbiosis of steel and drywall

    The symbiosis of steel and drywall

    Walk-in room-in-room solution
    Coop had been thinking about building a comfortable lounge for its employees for a long time. A 5-meter-high room, a kind of gallery, which is also adjacent to other rooms, was ideal for this purpose. But it would have been much too big, with its sand-lime brick walls, not comfortable and not heated. A room-in-room solution therefore offered itself, which could be implemented quickly, without a lot of dirt, but in compliance with all statics and fire protection requirements. Because the assembly took place while the high-bay warehouse was in operation, everything had to be well prepared and done quickly.

    Only half a day for the substructure
    As with all construction systems with a high degree of prefabrication, precise planning data and error-free transmission to the manufacturer were decisive. All steel profiles were cut to size and provided with the screw and punch holes to facilitate on-site assembly. The individual profiles could be efficiently screwed together using numbers and an assembly plan. Thanks to the corresponding planking, the entire construction has a fire protection rating of REI60. Plasterer entrepreneur Hansjörg Alder: “The steel structure was in the distribution center in just half a day, and within three days it was planked and ready for expansion.” You don’t notice the stylish room and its quality of stay that it was delivered as a kit and set up within a very short time.

    Like lightweight construction, simply much more stable
    RiModul® is actually nothing more than lightweight construction with stronger profiles. They achieve the best possible ratio of strength to weight, which among other things leads to dimensionally stable constructions – that is, walkable and resilient ceilings with additional usable area – and increased seismic resistance (earthquake security). And the system is based on the principle of prefabrication, which can reduce the overall construction time by up to 60%. RiModul® lightweight steel construction systems also result in significantly lower loads on the foundations than conventional construction methods. Complex objects in new construction and renovation can thus be realized safely, economically and with almost unlimited design flexibility. The RiModul® lightweight steel construction systems are particularly suitable for additions, extensions and, as in the case of Coop, room-in-room constructions. It also makes sense to use it as an external wall system for infilling in hybrid buildings.
