The safety of athletes was compromised when dangerous bulges began to deform the surface of an Olympic ice rink. The incident, which threatened to disrupt high-level competitions, required an immediate forensic investigation. Thanks to thermal 3D reconstruction and subsurface point cloud analysis, engineers were able to identify the root cause: a rupture in the vapor barrier that triggered moisture migration and the formation of ice lenses in the thermal insulation.
Forensic methodology: WUFI, Revit, and Leica Infinity in action 🛠️
The diagnostic process combined three key tools for a comprehensive analysis. First, Leica Infinity was used to process the point cloud obtained through subsurface laser scanning, generating a precise geometric model of the construction layers. This model was imported into Revit to visualize the damage distribution and plan the intervention. Subsequently, the WUFI software performed a detailed hygrothermal simulation, reproducing temperature and humidity conditions over time. The results confirmed that the vapor barrier rupture allowed water vapor from the ground to rise, condensing within the insulation and freezing. This cyclic freezing and thawing process generated the ice lenses which, upon expanding, lifted the rink surface, creating dangerous bulges for skaters.
Lessons for catastrophe prevention in critical infrastructure ⚠️
This case demonstrates that an apparently minor defect in a sealing layer can escalate into a serious safety risk. The methodology applied here, combining 3D scanning, BIM modeling, and physical simulation, should become a standard for periodic inspection of ice rinks and other climate-controlled infrastructure. Detecting abnormal moisture in the insulation in time allows action to be taken before ice lenses compromise structural integrity and user safety, preventing catastrophes that could cost athletic careers or even lives.
What 3D scanning methodologies allowed the detection of bulges in the ice rink before they compromised athlete safety during the Olympic competition?
(PS: Simulating catastrophes is fun until the computer crashes and you are the catastrophe.)
