At Ballast Nedam, we are putting this into practice as part of three tunnel renovation projects in South Holland. Together with Rijkswaterstaat and Movares, we have built an integrated 3D BIM model by intelligently collecting and consolidating data.

This digital foundation is now supporting us in the execution of the project and will also serve as a valuable basis for the management and maintenance of the tunnels in the future.
A detailed 3D BIM model has been developed for tunnels in South Holland, including the Noordtunnel. This model integrates information from sources such as 3D scans, scanned technical drawings, and 360° images. 
This creates a single, comprehensive, and up-to-date view of the tunnel: a solid digital foundation that strengthens collaboration and helps ensure more efficient and future-oriented renovation and maintenance.

This is only possible through effective collaboration across the entire chain, from engineering firms to clients and from contractors to operators. In this way, we are working together on the data-driven renovation and future-oriented maintenance of these tunnels.

In the video, Evert Jan Pluimers, Director of Ballast Nedam Infra, explains how we’re applying this approach to the Noordtunnel:

“By intelligently combining data and knowledge from various sources into a single model, we create clarity and insight. This enables us to make better decisions during the renovation and in the subsequent management.”
