An exciting day for our Robeton II project team and our students within the M1 Prototyping Project, RWTH Aachen University to Heinrich-Heine-Universität Düsseldorf (HHU) During the fieldtrip, the students have pitched their projects to the Bau- und Liegenschaftsbetrieb NRW (BLB NRW) representatives, Kevin Reschke and Christian Oelke, who are directly involved in the renovation and deconstruction of the HHU buildings. This was an excellent opportunity to receive realistic and relevant feedback from a real-life setting.

Together, we discussed what we can combine to actively contribute to circular economy and how to provide solutions for challenges in the building industry. The students then visited the HHU buildings and gathered information on precast reinforced concrete structures for potential reuse within the research framework of the Cluster of Excellence CARE - Climate-Neutral and Resource-Efficient Construction.

Furthermore, we had the chance to test on an existing building the semiautomated robotic concrete cutting process developed in the Robeton and Robeton II research projects. In the Robeton project series, we are investigating how safer conditions for workers, automated deconstruction and sustainability through reusability of concrete elements can be realized in future. The Robeton project is funded within Zukunftbau, Bundesinstitut für Bau-, Stadt- und Raumforschung (BBSR) and Bundesministerium für Wohnen, Stadtentwicklung und Bauwesen (BMWSB) (project number 10.08.18.7-22.15, project number 10.08.18.7-21.11).

The Robeton II project is a collaborative effort between, led by Prof. Sigrid Brell-Cokcan and her team Carsten Kamp, Emre Ergin, Martin von Hilchen and Nico and the Institute for Building Materials Research at RWTH Aachen University (ibac) led by Prof. Anya Vollpracht and her team Christian Helm and Christian Felten.

The M1 Prototyping Project is a collaboration between the Chair of Individualized Production in Architecture, and the involved researchers Iremnur Tokac Celikyay, Pranav Shevkar, Chu Han Wu, Prof. Sigrid Brell-Cokcan and Prof. Martin Claßen, Jan Hendricks from the Lehrstuhl und Institut für Massivbau as a future collaborators in the Cluster of Excellence CARE.

We are excited to share the final video of CLOUD56 – Scalable Cloud Architecture for 5G/6G RAN in Industrial Applications. The demonstrator showcases our integration of scalable cloud architectures with robot-assisted steel construction. It highlights how adaptive production workflows, skill-based robotic systems, and modular 5G IoT-enabled assets can be seamlessly connected through cloud-based technologies, enabling higher levels of automation in steel pre-assembly while being continuously monitored and optimized with linked-data approaches.

We gratefully acknowledge the commitment and contributions of our research team: Emre Ergin, Heinrich Knitt, Dr. Sven Stumm, and Prof. Dr. Sigrid Brell-Cokcan.

The “CLOUD56” project is funded by the Federal Ministry for Digital and Transport of Germany (BMDV) within the initiative InnoNT (funding number 19Ol22018C).

We’re excited to share the final closing video of our Construction Use Case within TARGET-X – the last milestone at the end of an exciting project journey on the 5G Reference Construction Site.

A huge thank you to all our CCR and RWTH-IP team-members and partners whose expertise and collaboration made this achievement possible.

The TARGET-X project is funded by the Smart Networks and Services Joint Undertaking (SNS JU) within Horizon Europe (funding number 101096614).

At the Campus Melaten of RWTH Aachen University, the Reference Construction Site opened its doors for the Open-Campus-Week 2025. Together, we celebrated the new Excellence Cluster CARE, the demonstrations of our industry partners within TARGET-X, and provided insights into cutting-edge research on 5G, robotics, and digital construction processes.

The event created a platform for networking and exchange between industry, politics, and academia – with inspiring discussions about the construction site of the future: from new design principles for deconstruction and circularity to safe human-machine collaboration.

The Open Campus Week impressively demonstrated how innovation, practice, and vision come together to make the construction industry more sustainable, efficient, and future-ready. Special guests Minister Ina Brandes MDL, Ministry of Culture and Science of the German state of North Rhine-Westphalia, Aachen Mayor Sibylle Keupen and the chancellor of the RWTH Aachen University Thomas Trännapp opened the special event, during which they had the opportunity to personally test the demonstrations.

As part of the TARGET-X collaboration with Concular and the StadtHürth we’ve taken a big step towards a more sustainable construction industry:

Building components from a building in Hürth have been carefully deconstructed and are now being reused at our ReStage demonstrator on the ReferenceConstructionSite of the CenterConstructionRobotics – giving materials a second life and proving that sustainability and innvoation go hand in hand. A digital and on-site Pre-Deconstruction-Audit (PDA) proved several materials to be good for another round. So together with our partner we decided to carefully dismantle these parts and now they are off to the project in Aachen. This project is a true example of how strong partnerships can drive circulareconomy in construction and set new standards for the future.

A huge thank you to everyone involved – together we’re reshaping the way we build! Prof. Sigrid Brell-Cokcan, Nicklas Spiegel, Ida Wetzel, Marit Zöcklein, Victoria Jung

The TARGET-X project is funded by the Smart Networks and Services Joint Undertaking (SNS JU) within Horizon Europe (funding number 101096614) to secure Europe’s leadership in 5G and 6G.
