GScan has completed all preparations to begin data collection at the Binckhorst Kindergarten in The Hague.

The preparation phase included a detailed simulation study, investigations of natural muon flux, and calibration measurements of steel, concrete, and reinforced concrete to enable automated material detection.

After careful planning, we decided to carry out the measurements with six scanners instead of the initially planned two. This will allow us to cover larger areas of hidden or confined structural elements and combine the scans into one large dataset. Once completed, the data will be integrated with 3D models previously developed by the University of Vigo.

The measurements will focus on the internal elements of external walls, slabs, and the elevator shaft. Our goal is to verify whether the structures were built according to the design documents and assess whether existing elements are suitable for reuse.

Because the scanners are placed more than three metres apart, the estimated measurement period is 21 days. This should provide enough muon flux information to detect hidden elements of the elevator shaft and determine the size and condition of key structural elements.

Importantly, the kindergarten will remain fully operational during the measurements, as the natural muon flux poses no disruption to daily activities.
