Fehmarn link prequalifiers unveiled 27 May 2013
Patrick Reynolds for TunnelTalk
Five consortia of contractors have prequalified to face off in a race to win the two main design-build packages for the 17.6km long immersed tube Fehmarn Link between Denmark and Germany. Confirmed today by project client Femern A/S, most will also compete on further packages for the mega-project. Subcontractors and consulting engineers associated with each group have also been named.

The prequalification process for the main civil works received submissions in January 2013, and preliminary bids for the two equal-sized contracts are to be made in 2014. A two-stage assessment process is planned and contracts are due to be finalised in 2015. The exact timing is subject to government approvals, which are expected in the early 2020s.

Two further contract packages went through the prequalification process with the results revealing that most of the same groups, or parts, are prequalified to bid for those works in different ways.

Three parties are prequalified to bid
Fehmarn Belt Contractors: bidding team, sub-contractors and consultants all the same as for the main tunnel packages under leaders Boskalis and Van Oord;
Femern Link Contractors: Dredging International (Lead) with Per Aarsleff, which is part of bid teams on the three other packages;

Jan De Nul: bidding alone and as part of the Immersia consortium for the main tunnel packages.
Femern A/S prequalified all JVs that applied for the four lots, and said they "proved strong enough to be allowed to bid for the project." In a statement, Femern A/S Technical Director, Steen Lykke, said he was "very satisfied" with the outcome, and added: "We anticipate healthy competition with regard to methods, innovation and price."
The project budget is cited as €5.5 billion (2008 prices). Later stages of procurement will see further prequalification steps for fit-out works.
