The construction industry is facing enormous challenges: A shortage of skilled workers, rising material costs and the pressure to build more sustainably and efficiently are forcing companies to find innovative solutions. Two key technologies that have the potential to significantly increase productivity in the construction industry are prefabrication and the use of robotics. These methods promise not only to speed up construction times, but also to improve quality and reduce costs and resource consumption.

The prefabrication of building elements in controlled factory environments has experienced an enormous upswing in recent years. With this method, large parts of a building – from individual wall elements to complete room modules – are prefabricated under optimal conditions and then transported to the construction site. This approach offers several key advantages over traditional construction methods.

First of all, prefabrication enables a significant reduction in construction times. While the foundations are being laid on site, the walls, ceilings and even entire room modules can be produced in the factory at the same time. This leads to a significant reduction in the overall construction time, which in turn saves costs and increases the profitability of projects.

Another key advantage is the increase in quality. In a controlled factory environment, precise manufacturing techniques and high-quality materials can be used that would often not be feasible on a traditional construction site. This leads to an improvement in construction quality, a reduction in errors and an increase in the longevity of the buildings.

Prefabrication also contributes to sustainability. Thanks to optimized production in the factory, material waste can be minimized and resources used more efficiently. In addition, precision manufacturing improves the energy efficiency of buildings, as elements such as insulation and seals can be installed more precisely.

The use of robotics in the construction industry opens up new dimensions of efficiency and precision. Robots can take on repetitive and dangerous tasks, which not only increases safety on construction sites, but also boosts productivity.

One area in which robots are already being used successfully is the 3D printing of building parts or even entire houses. This technology makes it possible to create complex structures with minimal material waste. 3D printing robots can work around the clock and are able to construct buildings in a fraction of the time that conventional methods would take.

Robots are also increasingly being used in assembly and finishing. Robot-assisted systems can, for example, lay tiles with the utmost precision or carry out painting work. This not only leads to an improvement in quality, but also relieves the burden on human workers, who can concentrate on more complex tasks.

Another promising area of application for robotics is construction site logistics. Autonomous vehicles and drones can transport and distribute materials, which optimizes the flow of materials and minimizes delays. This helps to increase the efficiency of the entire construction process.

The combination of prefabrication and robotics holds enormous potential for the future of construction. Robots can be used in production halls to manufacture prefabricated elements with maximum precision and speed. These can then be assembled on site by other robotic systems, leading to a seamless integration of factory production and on-site assembly.

This synergy makes it possible to maximize the benefits of both technologies. The quality control and efficiency of prefabrication are combined with the flexibility and adaptability of robotics on the construction site. The result is construction projects that can be realized faster, more precisely and more cost-effectively.

Despite the obvious benefits, the widespread implementation of prefabrication and robotics in the construction industry still faces a number of challenges. One of these is the initial investment in technology and infrastructure, which can be a hurdle for many companies. In addition, the use of these technologies often requires workers to be retrained and work processes to be adapted.

Another challenge lies in standardization and standardization. In order to exploit the full potential of prefabrication, industry and legislators must work together on uniform standards that enable the smooth integration of prefabricated elements into various construction projects.

However, the future prospects for productive construction through prefabrication and robotics are promising. As technological development progresses and the costs of robotic systems fall, the use of these technologies is becoming increasingly attractive. Experts predict that a significant proportion of construction production will switch to prefabricated and robot-assisted methods in the coming years.

The integration of prefabrication and robotics in the construction industry marks a turning point in the way we construct buildings. These technologies promise not only to increase efficiency and productivity, but also to improve construction quality and sustainability. While the challenges of implementation should not be underestimated, the long-term benefits clearly outweigh the risks. Companies that invest in these technologies at an early stage and integrate them successfully will secure a decisive competitive advantage in the rapidly changing construction industry. The future of construction lies in the intelligent combination of prefabrication and robotics – a revolution that has the potential to transform the entire industry and make it more sustainable, efficient and productive.

36 cities and municipalities in Lower Saxony are authorized

As part of the “Resilient inner cities” funding program, the state government of Lower Saxony is awarding 61.5 million EU funds for sustainable urban development. The city of Hamelin is one of the cities planning to apply.

As part of the “Resilient inner cities” funding program, the state government of Lower Saxony is awarding 61.5 million euros in EU funding for sustainable urban development. The city of Hamelin is one of the cities planning to apply.

36 cities and municipalities in Lower Saxony are eligible to apply for part of the 61.5 million euro funding pot. This was awarded by the European Regional Development Fund (ERDF) for the period 2021 to 2027. The 15 that submit the most convincing concepts on the topic of “resilient inner cities” will ultimately receive the funding. These range from 4.2 million euros in more developed regions (SER) to 3.95 million euros in transition regions (ÜR) per city or municipality.

“The ‘Resilient City Centers’ are a building block with which we support cities in Lower Saxony in making their city centers future-proof. Especially in our large state of Lower Saxony, cities have a very important function for the areas surrounding them. However, they are also facing major challenges – exacerbated by the coronavirus pandemic,” says Regional Minister Birgit Honé about the funding program.

Projects that are eligible for funding include the revitalization of inner cities, environmentally friendly land design, climate-friendly mobility and participatory processes for citizens. Among other things, the application requires the development of a strategy, which is divided into the chapters programme area, need for action and concept, cross-sectional objectives, participation processes, steering group and organizational structure as well as lead projects.

Applications from eligible cities and municipalities can be submitted by the deadline of 21.04.2022. These will then be formally reviewed by the Offices for Regional Development on the one hand and prepared for presentation to a jury of around ten people on the other. This jury evaluates the submitted plans on the basis of eight main criteria. On the basis of the jury’s assessment, the ESRE also selects 15 cities (nine in SER and six in ÜR) to benefit from the funding budgets. The Investitions- und Förderbank Niedersachsen NBank also advises on questions of eligibility for funding.

More information on the ERDF funding program “Resilient Inner Cities” in Lower Saxony can be found here.

Silently lost in haste

“Still lost in haste”. This is the title of Simon Ledergerber’s artwork, with which he won the Lucerne Art Society’s exhibition prize last week. “For me, the work is an exploration of the different stages of age that one goes through.

“Still lost in haste”. This is the title of Simon Ledergerber’s artwork, with which he won the Lucerne Art Society ‘s exhibition prize last week. “For me, the work is an exploration of the different stages of age that one goes through. The inner resilience changes,” explains the artist. A rusty steel plate with a rectangular Bernese sandstone at the end serves as a material analogy.

This is the second award in a row – only at the beginning of the month he won one of the grants from the Art and Culture Foundation of the Canton of Uri. And 2018 looks set to be another exciting year for Simon Ledergerber: For the Kunsthalle Arbon, he will be staging an exhibition covering 600 square meters in June. He will also be given his own space for his art as part of the exhibition prize in Lucerne: “This is an important platform for me,” explains Ledergerber. It is not yet clear what the artwork will look like. But it is certain that it will be a single work: “I would like to make a work that takes up the whole room.”

The project “Gigantisches Kleinod”, which was shown in 2016 in the exhibition Dall altra parte by Haus für Kunst Uri, was also an intensive exploration of space. It is a 300-kilogram cuboid attached to the ceiling of the Gotthard Fortress. “A hundred years ago, blasting and hand-picking took place here. I wanted to create a hand-chiseled counterpart.”

The material also played an important role – Ledergerber chose white marble as a contrast to the granite of the fortress.

Workshop or laboratory

The artist is also very interested in technique, as the material reacts differently to structures and external conditions. In this respect, he does not simply design a work and complete it – on the contrary: the process of working with the material is an essential part of the work.

According to Ledergerber, the results are not necessarily works that can be placed in the living room. But he is also not interested in making sellable art: “I want to dedicate myself to the cause. You owe something to the work.”
