The Norwegian Coastal Administration (NCA) plans to announce the tender for the Stad ship tunnel construction on December 1st 2024.

The regulatory plans were completed at the end of October. NCA has also finalized land acquisition and other preparatory work. NCA has made several changes to the competition framework since the previous market conference in 2023.

Interested contractors can find additional details in the documents available on Doffin in the last weekend of November and at the dedicated tender conference to be held on December 17 at the Radisson Blu Hotel in Gardermoen, where the the project will be presented and they will review key elements in the competition framework, including contract structure and evaluation criteria.  The tunnel construction will be announced as a turnkey contract (NS-8407) with negotiations.

The NCA envisions the following tentative timeline for the tender phase:


If all goes according to plan, construction could start in early 2026. The NCA has estimated the construction period to be just under five years. The proposal submitted by the chosen contractor must fall well within the total project budget of EUR432.75 million (NOK 5.06 billion), as approved by the Norwegian Parliament. If proposals exceed the budget, a revised cost framework may need parliamentary approval.
