TP26-07 Lidar and High-Resolution Imaging for Evaluating Agng Cooling Towers

Aging cooling towers present unique challenges for inspection and maintenance, often due to limited access, outdated documentation, and structural degradation. This presentation highlights the use of laser scanning (LiDAR) and high-resolution 360-degree imaging as powerful tools for non-invasive evaluation. LiDAR enables precise capture of as-built conditions, including structural and mechanical systems, while supporting the detection of tower movement or settlement through comparative point cloud analysis. Combined with 360° imaging, these technologies allow for remote identification of surface defects in concrete—such as cracking, spalling, and delamination—without the need for scaffolding or shutdowns. This approach enhances safety, reduces inspection time, and provides a digital baseline for ongoing monitoring. Case studies will demonstrate how these tools support proactive maintenance and extend the service life of critical infrastructure.
