Within the municipal boundaries of the municipality of Veenendaal, construction/development is regularly carried out and civil engineering work takes place.

In preparation for this, the following preparatory work is regularly necessary:

- Measurements for BGT/BAG: performing (flat-oriented) above-ground measurements for the Basic Registration large-scale Topography (BGT) and Basic Registration of Addresses and Buildings (BAG) partly on the basis of the client's object manual (IMGEO).

- Other surveying services: carrying out surveying work for preparatory civil engineering work or new construction projects, such as:

• Measuring the existing infrastructure (and the various objects);

• Performing various height measurements aimed at the GWW;

• Plotting of lots and plots.

It is estimated that an average of about 250 buildings and 20 infrastructure changes annually, spread over 4 measurement rounds on an annual basis.

It is estimated on an annual basis that about 20 lots and 10 other height measurements are being plotted.
