Skanska Wins Tunnel Contract

Skanska has won a contract worth NOK2.88bn (£247m) to carry out tunnelling work for a new water supply system in Oslo, Norway. The contract has been signed with Oslo municipality’s agency for water and wastewater services for preparatory work on the New Water Supply Oslo project.

The project primarily involves the blasting of rock chambers and three large tunnels with a total length of 5 km. A total of 1.2 million cubic metres of solid rock masses will be taken out and, when production is at its peak, Skanska will have seven tunnel rigs active.

The project is in an area in central Oslo that has a geology that will require special preparations, for example systematic pre-injection.

Construction will start in September 2020 and is due to be completed in May 2024.
