In 2012, after the foundation had acquired the school property, the course of the property boundaries and the terrain morphology were measured by a geodesy student of the University of Hannover. Local help was welcome when adjusting the reflector. The tachymeter was kindly provided by the University of Hannover for the duration of the survey of the property.
With the donation of a civil engineer / architect, the foundation now has a theodolite permanently available for measuring the buildings. An aspiring engineer familiarizes himself with the device.
