The contract has an estimated value of NOK 1.2 billion (CHF 131 million) and marks the start of the tunnel work for Fornebubanen.

Implenia was chosen for best offer as well as for meeting the contract's environmental and climate protection requirements. Fornebubanen recognized Implenia's implementation plan, its expertise in using BIM, as well as the response to the environmental and climate protection requirements.

“I am happy and proud that Fornebubanen has chosen Implenia for this complex project. It is perfectly aligned with our strategy of large, complex infrastructure projects with a high focus on sustainability and the use of new technologies”, says Audun Aaland, Implenia’s Head of Tunneling and Country President Norway.

“The bidders who invest most in alternative fuel technology and contribute to the electrification of machinery and facilities, came out best in this competition. The focus on sustainability seems to trigger good solutions, not only concerning environmental and climate protection, but also for the project overall. We look forward to a good collaboration with Implenia on this large and important tunnel contract”, says Grete Tvedt, project manager at Fornebubanen.

The contract signing will take place after a ten-day appeal period. The project start is planned in May 2021. Completion of the whole Fornebubanen project is scheduled for 2027, while the tunnel construction Lysaker – Fornebu is planned to be completed by autumn 2023.
