The combination of photogrammetry, bridge inspection, and structural health monitoring is transforming the way we manage and safeguard our bridges. By utilizing advanced technologies, these systems not only enhance the safety and efficiency of bridge inspections but also help prolong the lifespan of these critical infrastructures. As these technologies continue to evolve, they will play an increasingly important role in developing smarter, safer, and more sustainable transportation networks globally.
HiSCS is actively involved in the prestigious “SMART BRIDGES” initiative, which involves assessing 150 road and 100 railway bridges across Greece. This project will employ state-of-the-art systems to monitor the behavior of these bridges in real-time using Structural Health Monitoring (RTSHM) methods. HiSCS is responsible for conducting all survey activities using laser scanners, high-resolution cameras, and drones to create cloud models of each bridge and produce as-built drawings. It is anticipated that over 2TB of data will be collected for analysis and evaluation.
In addition, HiSCS inspectors will assess the current condition of the bridges, documenting any deficiencies to determine the overall condition of each structure. This data will be crucial for structural analysis and classification. During the inspection phase, a National Bridge Registry will be established and delivered to the National Bridge Authority. This platform will allow all bridge operators in Greece to access a Bridge Management System designed to support maintenance and repair needs.
The project requires HiSCS to engage 4 on-site survey teams, 6 off-site draftsmen teams, 3 inspection engineering teams, and 2 installation teams, including traffic coordinators, special vehicle operators, electricians, and technicians, all working together to manage the survey, inspection, and installation processes. Supported by the Greek Ministry of Public Works and the Technical Chamber of Greece, the project aims to predict structural failures early, enabling authorities to take swift action and prioritize repairs. This approach will optimize resource allocation, especially in light of climate-related risks.
HiSCS is proud to contribute to this project, which will help transform Greece’s aging bridge infrastructure— many built between the 1950s and 1980s—into “smart” bridges capable of real-time structural and functional assessments.
