The newly founded spin-off Constriq, originating from the Faculty of Civil Engineering at CTU Prague, leverages insights and expertise developed within the ROBOPROX research project. The company aims to revolutionize building digitalization by automating the conversion of 3D scans into BIM models, significantly reducing time and cost for pre-demolition audits and renovation planning.
Constriq s.r.o. is the first spin-off from CTU’s Faculty of Civil Engineering and the sixth spin-off in the entire CTU ecosystem. Its core mission is the development of software that automates the transformation of 3D point clouds from building scans into IFC-format BIM models. The company’s flagship products, Cloud2BIM and the upcoming Cloud2BIM-AI, address one of the biggest challenges in construction digitalization – the time- and labor-intensive process of creating accurate digital models. Traditionally, specialists spend days or even weeks manually processing scan data in CAD tools. Constriq aims to consolidate this workflow into a single tool, minimizing user intervention while maximizing efficiency.
The spin-off was founded by CTU academics, Doc. Václav Nežerka, Doc. Jan Valentin, Ing. Slávek Zbirovský, and Ing. Pavel Trávníček, Ph.D., with significant support from the CTU Technology Transfer Center, which guided the team through legal, licensing, and business processes.
Beyond 3D-to-BIM conversion, Constriq integrates autonomous units for in-building monitoring. These units continuously track selected parameters, displaying real-time measurements directly within the digital model. This enables not only rapid digitalization but also ongoing assessment of building conditions. The advanced algorithms and AI models behind Cloud2BIM-AI allow companies to save up to 90% of the time traditionally required for manual model creation, while improving model accuracy and consistency. This opens opportunities for smaller projects that were previously uneconomical due to high labor costs.
The open-source version of Cloud2BIM, developed under the European RECONMATIC project (Horizon Europe) and the UK Guarantee Programme, has already attracted attention from companies in the U.S. and Italy. Its development drew heavily from the ROBOPROX project, where Nežerka and Zbirovský contributed as part of CTU’s research team. Results have been published in Automation in Construction, highlighting international recognition and technological relevance. Direct engagement with potential clients confirmed strong demand for the automated solution. Existing tools on the market do not provide the same level of automation, positioning Constriq to deliver significant value in pre-demolition audits and renovation planning.
CTU has secured a 10% stake in Constriq through its subsidiary CTU Tech, demonstrating a strategic commitment to technology transfer and innovation commercialization. With the growing emphasis on building digitalization, digital twins, and mandatory pre-demolition audits, Constriq’s Cloud2BIM solution is well-positioned to scale rapidly. The spin-off exemplifies how high-level research can be successfully transferred into practical, market-ready solutions.
