Skanska wins Norway water tunnel contract

5 July 2021

Infrastructure firm Skanska has won a contract worth US$397m from the Agency for Water and Sewage in Oslo Municipality for the construction of a raw water tunnel between Hole municipality and Oslo, Norway.

The E5 contract comprises a 19km tunnel to be excavated mainly by two tunnel boring machines. It will stretch from a new water source at Holsfjorden, in Hole municipality to a new underground water treatment plant located at Huseby in western Oslo.

The contract is the second sub-contract in a major development project whose main goal is to ensure that Oslo's water supply can provide enough quantities of drinking water even in the event of failure in vital parts of the supply system. Skanska won the first sub-contract, for preparatory work, in August 2020.

Construction will start in August 2021 and is scheduled to be completed by 2027.

Skanska is a prominent construction and project development company globally, including operations in civil engineering and building construction in Sweden, Norway and Finland. It also develops residential and commercial property projects in home markets. During 2020, the firm had around 14,800 employees working in its Nordic operations.
