The renewal of the power plant, which was built in 1920, will last until spring 2022.
In January 2019, our team started the D15 Lovstakkentunnelen project in Bergen, Norway. The 90 million project includes the construction of two tunnels and two caverns as underground tram depots. The project will continue until February 2022.
The teams at CERN have finished excavating the
60-metre-deep shaft for the extension of the particle accelerator Large Hadron
Collider. The specially designed electric excavator could be used for this work
as planned. The cavern and the 300-metre-long tunnel will now be excavated until
The 8 km long Solbakktunnel was handed over on 01 February 2019. The team in Norway completed the two parallel tubes on schedule and handed them over to the satisfied client, Statens Vegvesen (Norwegian Road Authority).

The driving operations on the Vadlaheidi
tunnel in Iceland have been completed by the consortium Marti
Contractors and IAV.
Around 80% of the three 3'200m long tunnel tubes have been excavated.
The excavation works are half-way to completion. 880 meters are excavated from the east while over 560 meters are excavated from the west.
The traffic situation will be relieved by construction the third tube between Weinigen and Zurich-Affoltern.
In bright sunshine, the groundbreaking ceremony for the project took place on the local bypass Oberau on 01 September 2015 in Garmisch-Partenkirchen (Germany). The Federal Minister of Transport and digital infrastructure, Mr Alexander Dobrindt, was one of the party.
