In the Netherlands, utility networks in built environments are almost always located underground. For the expansion or renovation of these networks, it is essential that network operators can rely on accurate registration of the existing infrastructure in a geographic model. Although network operators usually prepare the design for network maintenance and expansion themselves, the execution is often outsourced to external contractors and subcontractors.

In practice, the completed network expansions regularly deviate from the original design, as on-site adjustments are made due to obstacles or undocumented situations. To keep the current situation transparent for all involved parties, the new network assets are registered in the field, preferably while the trench is still open. This task falls to the contractors, who use measuring rods—often supported by GPS—to accurately map the new pipes and connection points.
