Technical tours on Thursday 8 September

1. The Fehmarnbelt tunnel - FULLY BOOKED


From 11:00 to 15:00 (in Rødbyhavn, Lolland). The transfer bus will leave from Bella Center at 9:00. The return is programmed to be approx. 17:00. Water, coffee/tea and lunch included - max. 80 guests.

The visit consists of general presentation of the Project on the construction site including a visit to the exhibition center, visit to the production facility, portal area construction site and work harbour.

Together with the Employer Femern A/S, the selected Contractors (Fehmarnbelt Contractors and Femern Link Contractors) are constructing an immersed tunnel between Denmark and Germany. The Fehmarnbelt tunnel consists of:

  • 18 km of immersed tunnel
  • Two tunnel portals built in both Denmark near Rødbyhavn and in Germany near Puttgarden
  • 89 elements, which will be produced at the factory in Rødbyhavn immersed one by one and assembled underwater connecting the Danish and German sides
  • Budget of approx. DKK 52.6 billion

Construction works started (on the Danish side) in 2020 and on the German side the following year.

With this new connection, the journey between Rødbyhavn and Puttgarden will take seven minutes by train and 10 minutes by car.

WTC would like to invite you to visit one of the most exciting tunneling projects taking place in Denmark right now.

Short description of the construction phases:

In order to construct the tunnel elements a large production facility is being erected on Lolland. Construction of the production facility takes 2 years in itself.

When the factory is in operation, a standard element will be produced approximately every second week for some three and a half years. Production of 79 standard and 10 special elements will be required in total.

An 18 km long trench from Denmark to Germany will be dredged to accommodate the tunnel elements. The tunnel elements will be immersed into the trench, joined together and covered with gravel, sand and stone.

A portal building will be constructed around the descent into the tunnel on the Danish and German sides. The portal facilities will connect the tunnel railway and motorway with the upgraded and partly newly built roads and railways in the hinterland. 

The tunnel tubes will be equipped with the technical installations, which include ventilation, communication facilities, lighting, signage and the motorway and railway installations.

2. M4 Sydhavn - the new metro line in Copenhagen: - FULLY BOOKED

The visit consists of general presentation of the Project on the construction site focusing on tunnelling technology.

The Employer Metroselskabet together with the Contractor “TUNN3L” are constructing a new metro line in the city of Copenhagen. The new line, called M4, is an extension to the existing metro system going from the inner city to the Southern part of Copenhagen (Sydhavn).

The Project in numbers:

  • 4.5 km of twin tunnel
  • 5 underground stations + 2 cross over+ 1cross passage
  • Transfer tunnel to S-train station
  • Connection to the Cityringen metro lines
  • Budget of approx. DKK 9 billion

Currently the metro tracks are being installed and the civil works are progressing at the stations. The Project is expected to be finalized in 2024.

All five underground stations in Sydhavnen have been specially designed to have art in the station room itself and thus becoming an integral part of the architecture.

It is the first time that art will be incorporated into the construction of the stations from the very beginning, and the Danish Arts Foundation has selected five renowned artists to create works for the metro stations.

When the project has been completed, the southern part of Copenhagen will be connected to Cityringen and the branch off to Nordhavn. The new metro system will contribute to an even stronger public transport network in the metropolitan area of Copenhagen.

9:00 to 11:00 or 13:00 to 15.00. Water and coffee/tea included. Max. 20 guests per visit.
The visit consists of general presentation of the Project on the construction site with focus on use of underground space and their architectural design.

Denmark is currently building one of the largest museum constructions in recent times with a large underground extension. The new building of the Natural History Museum of Denmark is conceptualised as a congregation of the natural sciences, by bringing together the Geological, Zoological and Botanical Museums in the heart of Copenhagen.

The Danish Road Directorate is the Employer, and Per Aarsleff is the Contractor assigned for the job. The Budget is approx. DKK 1.2 billion and expected to be finalised in 2023.

The new museum is built within an area of approximately 30,000 m2, where approximately 15,000 m2 consists of total refurbishment of existing buildings, which were part of “Polyteknisk Læreanstalt” (the technical university), where engineers was educated in physics, chemistry and mathematics in 1890 until it was moved to another area away from the city centre (Lyngby/Lundtofte).

The future new buildings are approx. 15,000 m2 and the construction works is unusually complicated with curved walls, stairs and decks made of casted concrete. The new buildings are partial constructed underground.

In the center of the area, a dome-like structure combining the underground facilities with the surface is going to house the museum's unique collection of large mammal endoskeletons. It is called Ocean Hall and it gives the visitors an opportunity to experience 'beautiful scenery' and 'unique architectural’ in the heart of Copenhagen. Whale skeletons will be hanging from the ceiling in the future museum exhibit.

Come and join WTC for a unique architectural experience underground!

Use your travel pass to get there. Nørreport station is just next to the museum.

Price: all visits 10€ (DKK 75).
