Abstract. Whatever the age of a large structure (dam, viaduct, cooling tower, nuclear containment, tunnel, …) It has to be periodically monitored. It is a challenge to realise these services when the access is limited and difficult for Man. This paper introduces a global approach, developed by SITES, through examples of application on different concrete dams or cooling towers, and their results. This global method involves three techniques: the SCANSITES® (a visual inspection system), the LIDAR (3D laser scanning) and high resolution photogrammetry.
