European cities are facing growing challenges caused by aging underground infrastructure, limited space for new development, and the increasing impacts of climate change. Construction and maintenance projects often suffer from delays, safety risks, and extra costs due to a lack of reliable information about subsurface conditions. Existing underground maps are typically outdated, incomplete, or inconsistent across sectors.
The Widmo Cities project aimed to address this gap by adapting advanced Spectral Ground Penetrating Radar (SGPR) technology for use in complex urban environments. The project’s goal was to demonstrate how non-invasive, high-resolution subsurface imaging can support safer construction, better infrastructure management, and improved urban resilience.
Through technology adaptation, pilot testing, and preparation for commercial deployment, the project enabled cities and infrastructure operators to access detailed underground information more efficiently. The results contribute to reducing excavation risks, improving planning accuracy, and supporting sustainable, data-driven urban development across Europe.
