“Stake out” means the transfer of planned geometry into the nature - mostly the building site. Its result contains of a topological sketch and of the nails on the profile board. These nails give the user a picture of an accuracy of about 2 to 3 [mm]. The DIN 18202 Norm mentions a threshold of 20 to 30 [mm] for upcoming discrepancies at the raw building. So nothing can go wrong!? Far wrong! If such discrepancies shall go below this limit, the survey result is not allowed to be bigger than 7 to 10 [mm]. This again means that a shortfall of an accuracy of ± 5 [mm], the most of which is normally needed for the identification accuracy of the points of origin. The “GEOHAUS Stake Out” consists of 22 single steps with a lot of measures to hold off the different risks.
