Platform tunnel below Slagelse Station

The project includes rehabilitation of approximately 80 m of tunnel below Slagelse Station. The tunnel is located below 7 railroad tracks that operate one of the main railway passages in Denmark.
The project includes upgrading of the structure in regard to new regulations of load-carrying capacity. At the same time the tunnel was protected against penetration of moisture in forms of a new waterproofing and draining system. Inside the tunnel the pavement and lighting has also been renewed in a way that makes the tunnel appear as a friendly and safe passage.
Especially the work on the upper side of the tunnel demanded great caution and timing in regard to maintain the running of the railway tracks. The project is an example that NIRAS can manage cases that involves multi disciplinary assignments. Besides knowledge of concrete and material technology, knowledge of railway technology, draining and environment was included.
