Norway's Birdsview raises €3.7 million to scale its "MRI for concrete" technology and protect infrastructure.

Norway's Birdsview raises €3.7 million to scale its "MRI for concrete" technology and protect infrastructure. August 17, 2026 Birdsview, a Bergen-based startup specialising in concrete inspection technology that helps preserve infrastructure, has raised €3.7 million to strengthen its commercial, industrial, and international scaling. The round was backed by Sarsia, Butterfly Ventures, Proptechfonden, Kiilto Ventures, Nordic Makers and Momentum. Existing investors Eviny Ventures, Farvatn Venture, Erik Bakstad (Ardoq), Gunnar Hvammen (serial founder) and Herman Flinder (founder of Norse Partners) also participated in the round. "This funding round is an important milestone for Birdsview. With €3.7 million (NOK 40.5 million) secured, and a Nordic investor consortium that understands both our technology and our market, we now have the resources to scale commercially and industrially across multiple countries. The fact that customers in eight countries have already chosen Birdsview Concrete just weeks after launch shows that we are solving a real problem for the industry," said Olav Skogen, CEO, Birdsview. Founded in 2017 by Skogen and Simen Husøy in Trondheim, Birdsview offers "MRI for concrete" technology to protect infrastructure. The company has developed a platform that enables users to see inside concrete without breaking it. The company states that it combines sensors with proprietary algorithms that automatically process and analyse data into detailed 3D models of concrete structures, without the need to drill into or damage the structure being inspected. This makes it easier to preserve existing concrete structures, with lower risk, reduced costs, higher efficiency and substantially less environmental impact. The Nordic startup states that it utilises Ground Penetrating Radar (GPR) to apply radar pulses to image objects. It further notes that, although GPR technology is powerful, there are traditionally some limitations that prevent its full potential from being utilised. Birdsview claims that its technology solves these challenges. According to the company, expertise in radar analysis and signal interpretation is often required to interpret raw GPR data. Complex data plots must be interpreted to image what one is looking at, and this is often difficult and time-consuming. The startup solves this by automating data interpretation with its algorithms, so anyone can create images of the data. Once the raw data is processed and successful imaging is available, the next step involves understanding what the image implies. Materials must be classified, and the effects of anomalies must be understood to assess the integrity of the object under evaluation. Birdsview states that its software automates this process, making the results easy to read and understand. In 2025, the company launched its first concrete product and developed a technology platform powered by Full Waveform Inversion, ready-made sensors, and AI-driven analysis. Birdsview reports that since then, more than 100 different concrete structures, ranging from buildings to bridges, have been scanned using this technology. In March 2026, Birdsview took the next step by beginning to pre-sell the product, allowing customers to start using the technology themselves. Since then, customers in nine countries have purchased the product. Over the past two years, Birdsview has worked with major Nordic and global companies on its customer and partner list, including Vinci, Bouygues Construction, The Trust for Governors Island, EllisDon, Sweco, Asplan Viak, and Rambøll. The company has offices at Startup Lab in Bergen and Oslo and employs 14 people.

Mississauga hospital project named ijglobalppp deal of the year. Posted on March 24, 2026 The project to build The Peter Gilgan Mississauga Hospital and Shah Family Hospital for Women and Children has been named the 2025 IJGlobal PPP Deal of the Year - North America. The consortium behind the project, which includes EllisDon, PCL, Fengate Asset Management and Plenary Americas, accepted the award earlier this month. Although the IJGlobal Awards ceremony is primarily geared toward equity investors and developers, EllisDon says the success of the transaction reflects the efforts of hundreds of individuals across design, construction, facilities services, and other teams. "This recognition highlights the strength of the public-private partnership model and the close collaboration between development partner PCL, clients Trillium Health Partners and Infrastructure Ontario, and equity partners Fengate Asset Management and Plenary Americas," said Jeff Brace, Head of Infrastructure, EllisDon Capital. "It also reflects the important contributions of lenders and advisors who helped establish a new benchmark for megaproject financing in Canada. While the full list of contributors is extensive, this award belongs to everyone who played a role." The IJGlobal Awards celebrate outstanding greenfield and refinancing projects across the global energy and infrastructure sectors, recognizing teams that successfully deliver complex deals with lasting value.

Case Study: Hospital Implements Gas Monitoring with DOD64 FTIR Technology

Case study: hospital implements gas monitoring with DOD64 FTIR technology. A leading healthcare facility in Ontario, known for its commitment to maintaining the highest safety and compliance standards for patient care and the workplace environment, chose DOD Technologies for their gas monitoring needs. Under national guidelines, hospitals in Canada are required to perform annual spot and leak checks for anesthesia gases, including sevoflurane, desflurane, halothane, nitrous oxide, and formaldehyde. Traditionally, these inspections were conducted bi-annually by government agencies - an approach that proved costly, time-consuming, and disruptive to hospital operations. With rising costs associated with mandated gas leak inspections and the logistical challenges of coordinating agency testing, the hospital needed a more efficient and affordable solution to maintain compliance without compromising accuracy or safety. EllisDon Facilities Services, responsible for the hospital's equipment maintenance, recognized the need for a permanent, automated gas monitoring system that could provide real-time data and reduce dependence on external testing services. Additionally, multiple facility staff members were relying on handheld leak detectors to manually sample for anesthesia gases - a labor-dependent process that also lacked consistent coverage. DOD Technologies partnered with EllisDon to implement the DOD64 FTIR Gas Detector, a state-of-the-art gas monitoring system capable of simultaneously detecting multiple anesthesia gases in real time. The DOD64's Fourier Transform Infrared (FTIR) technology provides high sensitivity and specificity across a wide range of target gases, making it ideal for healthcare environments where accuracy and safety are paramount. By deploying the DOD64, EllisDon and the hospital gained: * Sequential, automated gas monitoring for all required anesthesia gases * Reduced operational costs by eliminating the need for frequent agency inspections * Enhanced safety through constant leak detection and alerting * Improved efficiency by replacing multiple handheld detectors with a single, centralized system Since the installation of the DOD64, the hospital has achieved: * Significant cost savings compared to bi-annual government testing * 24/7 real-time monitoring that ensures constant compliance with national standards * Increased staff productivity, freeing personnel from manual leak testing * Confidence and peace of mind knowing anesthesia gas levels are routinely tracked and reported DOD Technologies is proud to support EllisDon Facilities Services, hospitals and other commercial/industrial facilities with comprehensive, cost-effective, and reliable gas detection solutions. The DOD64 FTIR system not only meets stringent compliance requirements but also delivers long-term value through sequential monitoring, enhanced safety, and reduced maintenance costs. DOD Technologies - The Leader In Low-Level Gas Detection - continues to set the standard for innovative gas detection solutions in healthcare and beyond. Contact DOD Technologies, Inc. today to discuss your gas detection challenge and to customize a solution that meets your needs.
