Mandatory notice of mechanical excavations

Are you planning to carry out mechanical excavations? If so, first submit an orientation request on time. This will inform you about pipelines and cables that may be in the ground at your intended excavation site. However, the orientation request does not allow you to start excavations. For that, an excavation notice (a so-called KLIC notice) is required from the Kadaster (the Netherlands Cadastre, Land Registry and Mapping Agency).

Under the WIBON (the Netherlands act for information exchange regarding overground and underground grids and networks), it is mandatory to report mechanical excavations beforehand to the Dutch Cadastre's Cable and Pipeline Information Centre (KLIC).

Mechanical excavations? Follow the steps set out below

1. Submit an orientation request (not mandatory)

You want to be well prepared but you haven’t yet decided on the exact location? Submit an orientation request to the Netherlands Cadastre, Land Registry and Mapping Agency (Dutch website Kadaster). The information that you receive contains information on the location of underground cables and pipelines, as well as on the contact details of network managers. They are the owners of cables and pipelines in the terrain where you want to carry out excavation work. Please send your questions about the location of a DPO pipeline to vgi@dpo.mindef.nl.

2. Report excavation work to the Kadaster (mandatory)

You must always report excavation work beforehand to the the Cadastre’s Cable and Pipeline Information Centre (Dutch website Kadaster/ Kabel en Leidingen Informatie Centrum/KLIC), even if you have first submitted an orientation request.

3. Report the excavation work to the Kadaster's Cable and Pipeline Information Centre no earlier than 20 working days prior to the start of the excavation work

You will receive up-to-date cable and pipeline information (area information) from the Kadaster within 2 working days. This area information must be available at the excavation site at all times. Submit your notification no later than 3 days prior to the start of the excavation work.

If there is a DPO pipeline in the ground at your intended excavation site, the excavation notice (KLIC notice) is sent to the DPO. You will automatically receive a letter from the DPO stating that the pipeline supervisor will contact you to discuss your excavation activities. Together with the supervisor, you then make arrangements on how to carry out the excavation work near the DPO pipeline.

The Kadaster will always provide you with an overview of network managers of networks in the excavation area. Depending on the location where you have planned your excavation work, you will receive information on DPO pipelines and cables, and on other network managers.

4. Check whether a precautionary measure requirement applies

It is possible that the area information includes a precautionary measure requirement. This is an additional warning about an important cable or pipeline in the ground. Is it a DPO pipeline? If so, please contact the DPO to discuss the measures to be taken.
