Hochtief Infrastructure and Implenia has jointly been awarded the contract to build a 14 km power supply tunnel in Stockholm, Sweden.


The contract is about $ 102 million. Hochtief and Implenia have equal shares. Hochtief will also be the technical leader. The Anneberg-Skanstull Tunnel is part of the City Link project and is intended to improve the electricity supply in the greater Stockholm area.

Klaus Grüttner, EVP at Hochtief Infrastructure said: “We are delighted that this contract in Sweden gives us another opportunity to demonstrate our tunnel-building expertise.”

According to a statement from the company, the construction will be carried out with the help of a tunnel-driving machine which will be used to build the tunnel which has a diameter of five metres and will be located 50m to 100m below ground. The project will encompass six shafts, elevators, and the construction of technical buildings for electrotechnical equipment.

Construction is scheduled to be completed by 2024.
