Mapping corrosion, spalling and cracks on a water tower

Structure and inspection scope

Built in 1966, the Collex-Bossy water tower combines a hyperboloid lower section with a truncated cone above. Its geometry required a carefully adapted inspection flight plan.

Inspection methodology

SwissInspect planned image acquisition following the tower’s shape. The trained AI models detected exposed rebars, corrosion, spalling and cracking.

Inspection results

The 3D mapping of detected damage, together with the quantified measurements of cracks, exposed reinforcement, corrosion, and spalling, helped engineers plan the required retrofitting work.
