Company wins second contract for Rogfast tunnel project

Opfikon ZH, June 2024

The construction company Implenia, together with its partner Stangeland Maskin, has won a second contract in the Rogfast tunnel project. The 8.8-kilometer-long E02 Kvitsøy tunnel will be built under the sea surface in southern Norway and includes a contract volume of 420 million Swiss francs for Implenia.

Construction company Implenia has won a second sub-project in the Rogfast tunnel project with its Norwegian partner Stangeland Mask in. E02 Kvitsøy is even more complex than the E03 Boknafjord Tunnel, which Implenia is already building together with Stangeland Maskin as a joint venture, and is worth CHF 420 million to Implenia. The order value for the entire project is CHF 540 million

“We are proud to have been selected for this important project together with our joint venture partner Stangeland Maskin,” said Erwin Scherer, Head of Tunnelling at Implenia, in a press release. “E02 Kvitsøy is another complex tunnel project and therefore fits perfectly with our strategy, and we will contribute our extensive expertise in tunnelling, concrete and water and frost protection.” The contract with the Norwegian Public Roads Administration is scheduled to be signed on 7 June.

E02 Kvitsøy is an 8.8 kilometre long two-way tunnel with a cross-section of 10.5 metres. It is to be built south and north of Kvitsøy in Fylke Rogaland in southern Norway at a depth of around 230 metres below the sea surface. The tunnel includes two ventilation shafts, a junction with ramps and a roundabout as well as 1.6 kilometres of road in the daytime area, two bridges and a large sea embankment. An industrial estate is to be built on this. Work is scheduled to start in late summer 2024 and be completed in 2030, with Implenia holding a 77 per cent stake and Stangeland Maskin 23 per cent in the joint venture. Implenia is responsible for tunnelling and lining the tunnel in the upcoming construction project, while Stangeland Maskin is responsible for material transport, including backfilling, earthworks and road construction in the tunnel and surface areas.
