Digital tools drive efficient railway renovation in Amsterdam

At Amsterdam Central Station, advanced geospatial technologies played a crucial role in the recently completed renovation of the IJ Viaduct. Dutch infrastructure specialist BAM, working on behalf of ProRail – the organization responsible for railway infrastructure in the Netherlands – used 3D modelling, Lidar scanning and point cloud analysis to inspect, plan and execute the complex works beneath tracks 14 and 15 and platforms 5 and 6. The result: a fully restored steel viaduct that can now support the rail network for another 50 years.

The renovation was carried out in one of the busiest and most logistically challenging locations in the country, with trains continuing to run and the station remaining open throughout. Digital technologies ensured minimal disruption and maximum efficiency. Lidar scans generated highly detailed point clouds of the structure, providing accurate input for a digital twin that guided the renovation process from planning to execution.

After 100 years in service, the IJ Viaduct had reached the end of its technical lifespan. BAM Infra, a division of Royal BAM Group, removed the concrete from the track trough to assess and preserve the steel supporting structure. New concrete was poured and the platform walls were rebuilt to meet modern standards.

Part of a wider modernization effort

This project is one element in ProRail’s larger strategy to modernize Amsterdam Central Station, increase capacity and improve connectivity with the rest of the Netherlands and Europe. “Thanks to the dedication of our team, smart digital technologies, and close collaboration with ProRail and other partners, we have delivered a future-proof solution within the planned timeframe,” said Alfred Siemes, director at BAM Infra Nederland. “This project shows how we can carry out complex renovations efficiently, with minimal disruption and maximum quality.”

The renovation of the IJ Viaduct was strategically combined with the replacement of the first Oostertoegang rail bridge – also known as the Eastern Passage, a key rail connection located on the eastern side of Amsterdam Central Station. By coordinating these efforts during the same track closure window, ProRail minimized disruption and accelerated overall progress. Meanwhile, BAM is also working on the renovation of the entrance to the western passenger tunnel, located on the city side of the station.
