The total contract value of the new project E02 Kvitsøy amounts to more than CHF 540 million.
The E02 Kvitsøy contract is deemed to be one of the most complex parts of the Rogfast project including a two-way tunnel approximately 8.8 km long with a 10.5 m cross-section. It will extend south and north of Kvitsøy at approximately 230 m below sea surface.
The JV will also provide the complete interior finishing, technical buildings, pumping stations and further installations.
Additionally, the project includes two ventilation shafts, an interchange in the tunnel with ramps and roundabouts, 1.6 km of road in the day zone, along with two bridges and a large marine fill that will be used to create a commercial area.
Implenia is already building the E03 Boknafjord tunnel together with Stangeland Maskin, which means that the JV builds around 70 percent of the entire Rogfast project.
On project E02 Kvitsøy Implenia will be responsible for the tunnelling and the interior finishing of the tunnel, while Stangeland Maskin will be in charge of the transportation of materials, including sea fill, ground works as well as road construction in the tunnel and day zone.
Erwin Scherer, Global Head Tunnelling at Implenia said: “We are proud to be chosen for this important project together with our JV partner Stangeland Maskin. E02 Kvitsøy is another complex tunnelling project and therefore fits perfectly with our strategy. We will contribute our vast expertise in tunnelling, concrete as well as water and frost proofing,”
The contract between Implenia, Stangeland Maskin and the Norwegian Public Roads Administration is scheduled to be signed after the objection period ends on June 7, 2024.
The work starts in late summer of this year and is planned to be completed in 2030.
