Qatar Launches World's Largest 3D-Printed Construction Project
In a global first for large-scale digital construction, UCC Holding, in collaboration with Qatar's Public Works Authority (Ashghal), has officially begun the printing phase of the world's largest 3D-printed building project.
The initiative marks a significant leap in sustainable infrastructure development and positions Qatar as a regional pioneer in advanced construction technology, a media report on UCC Holding website said.
The project involves the construction of 14 new public schools, including two to be built entirely using 3D printing technology. Each of the 3D-printed schools will span 20,000 square meters—making a combined 40,000 square meters—40 times larger than any previously completed 3D-printed building worldwide.
Designed as two-storey buildings on plots measuring 100 by 100 meters, the schools represent a landmark in educational architecture and scalable, future-ready infrastructure in the region.
To execute this unprecedented build, UCC Holding partnered with COBOD, a Danish company recognised as a global leader in 3D construction printing. COBOD has supplied two custom BODXL printers, each measuring 50 meters long, 30 meters wide, and 15 meters high—comparable in size to a Boeing 737 hangar. These are currently the largest construction printers in the world.
Following months of site development, equipment assembly, and simulation testing, the printers are now fully operational.
UCC Holding has formed a dedicated team of architects, civil engineers, material scientists, and printer technicians to lead the operation.
Over the past eight months, the team conducted more than 100 full-scale test prints using a BOD2 printer at a trial site in Doha. These trials helped develop optimized concrete mixes suited to Qatar's climate and refine a custom nozzle for high-precision printing.
In May 2025, the team completed intensive training with COBOD engineers, covering everything from printer operation and structural layering to live quality control—strengthening Qatar's local capacity for high-tech construction methods.
3D printing offers significant environmental, social, and economic advantages over traditional construction. The process reduces raw material waste, minimizes concrete use, and cuts carbon emissions. On-site printing also reduces transportation needs and supply chain dependency, while dramatically speeding up project timelines.
Printing is scheduled to take place at night to improve concrete performance and mitigate heat-related challenges—while also reducing dust, noise, and community disruption.
Architecturally, the schools feature flowing, curved walls inspired by Qatar's desert landscapes and sand dunes. These complex, organic shapes are made possible by the design freedom 3D printing allows—achievements that would be prohibitively difficult or expensive with conventional methods.
The two 3D-printed schools are expected to be completed by the end of 2025. The project not only signals Qatar's growing leadership in innovation and sustainability but also sets a new benchmark for educational infrastructure development globally.

Danish brewer adds AI ‘colleagues' to human team
AFP | Fakse They have names, faces and email addresses, but the five new colleagues at Denmark's Royal Unibrew only exist in the virtual realm, which the brewer hails as a milestone to unleash the full potential of its staff. 'What we as humans are good at is our creativity, our empathy, our knowledge of our customers,' marketing director Michala Svane told AFP. Svane explained that working together with their digital colleagues, their human employees 'get help for more routine-based work and finding information'. With the help of Danish company Manifold AI, she has enriched her team with five AI 'colleagues': brand specialist KondiKai, market analyst Athena, Prometheus, who gathers all sales data, Moller, a sommelier specialising in pairing food and beer, and trade specialist Ella. Initially, the assistants operated without names, but the five 'colleagues' now all have a backstory, can swap outfits, and interact daily with other employees. The company has made photos of the 'colleagues' -- three men and two women, all attractive and fit -- and human employees interact with them via chats and emails. 'When we put a picture on the AI agent, the use and the engagement went up times four,' Svane said. According to Svane, she hasn't sensed any apprehension from the human staff in accepting their virtual co-workers. Jan Damsgaard, a professor specialising in digital transformations at Copenhagen Business School, explained that AI employees are often designed as 'personas' for a better user experience for those interacting with them. 'They are created to attend to special issues,' Damsgaard told AFP. At Royal Unibrew, Denmark's second-largest brewer, Karin Jorgensen, who heads the team responsible for data collection and analysis and converses daily with Athena, her 'sparring partner.' At the moment, she is interested in the non-alcoholic beer market, and conversing via the instant messaging service Teams Athena guides her through already completed reports and an overview of the market. 'Before, there were a lot of emails coming in. And we had to look up old reports and do a lot of connecting things and so on. We have definitely moved to more agility, more speed,' Jorgensen told AFP. Another advantage, she said, is that analysis and collating information can be kept in-house. 'We are getting much more value and getting much more effective as we work,' the analyst said. Jorgensen is also anticipating further developments, such as Athena being able to participate in meetings. Critical thinking While this new relationship can make employees more productive, they need to be mindful that they maintain their critical thinking skills, one of the managers Lise Knuppert Hordam warned. 'You need to be critical of everything that comes from KondiKai because he is a machine,' she said. 'What he says is based on all the data we gave him. So it is valid what he says, but it needs a human touch and creative thinking,' she said. The development of these new tools, or 'colleagues,' is not only a technological feat for Michala Svane, but it is also laying the foundation for a hybrid team of humans and AI co-workers that work together effortlessly. But every new technology also carries risk, according to Damsgaard. In this case, what raises questions are the interactions between employees and their AI colleagues: what happens when your closest colleague is an AI collaborator and not a real person? What do you do if a human colleague conflicts with an AI co-worker? 'It 's something we know little about,' the researcher said, adding that he hoped such questions will get answered as the technology developed.
