During the construction of the 2nd Coentunnel, Tunnel Safety Consults has been active in the construction plan and the compilation and organization of the design team. Furthermore, we analyzed contract requirements to create a good starting point. We designed the ventilation and lighting systems (street lighting and tunnel lighting). We also designed the exhaust emission (see picture). We will often think back on this when we breathe the fresh air and see the beautiful lighting of this underground work of art.
