The Order with reference 1-D-08011-23 is about carrying out various surveying projects on demand and as required within the entire territory of the municipality of Rotterdam.

Deformation measurements take place, among other things, to monitor horizontal and vertical shifting of quay walls, bridges, tunnels or buildings, etc. Through repeated measurement, it becomes visible over time whether the object is subject to deformation. Deformation measurements help to detect risks at an early stage and allow appropriate measures to be taken.

For large and small infrastructural work, the Basic Information Department carries out surveying measurements on request. These measurements serve as a basis for creating a new design. An up-to-date situation measurement prevents errors and problems in the implementation. For large and small infrastructural work, the Basic Information Department carries out surveying measurements on request.

The surveying of cables and pipes concerns the registration of all licensed cables, pipes, above-ground cabinets and underground objects in the publicly accessible outdoor space in the municipality of Rotterdam. The work is to perform measurements with which the pipe collection card is kept up-to-date. This is in order to be able to accurately determine future routes, and not to delay their execution by encountering unknown cables, pipes and underground objects, in the subsurface of the Contracting Authority.
