As some tunnel issues in the Netherlands may also be internationally relevant, a number of COB publications related to tunnels are available in English. This page provides an overview.

Living document Renovation tunnels 

Many tunnels in the Netherlands need to be renovated in the coming years in order to keep them safe and adapted and smartly maintained to meet changing requirements. This raises all kinds of questions. The COB network seeks to jointly develop, combine and utilize knowledge. This includes knowledge of both organizational and technical aspects. This digital living document bundles this knowledge.

Living document Cybersecurity tunnels

Tunnel professionals often have insufficient information about the cybersecurity of their tunnel. The COB network has therefore prepared a so-called living document on this subject. This online manual enables the (tunnel) manager to assess the digital resilience of his object and to optimise the processes in the field of cybersecurity.
