Right now we continue our work on preparing the tender document and technical support for the Environmental Impact Assessment (EIA) in Denmark and in Germany. This time though, I will follow up on the four main contracts of the Fehmarn belt tunnel project and elaborate on the competitive dialogue described in the prequalification documents.
The contracts are so-called ‘design and build contracts’ where the contractors design their own project, but within a given framework in the tender documents.
Building the coast-to-coast link is such a large-scale and complex project that Femern A/S has divided the civil works into four major construction contracts. Several large, international contracting companies are expected to join forces in consortia in order to handle the job.
- The first contract concerns dredging of the seabed and land reclamation. Here the contractor is to dredge a trench, approx. 18 km long, approx. 80m wide and approx. 12m deep, in the Fehmarnbelt, where the tunnel will be placed.
- The second contract concerns the construction of the northern section of the tunnel, i.e. on the Danish side. The contractor is to carry out half of the actual tunnel construction and consequently build half of the tunnel element at a construction facility in Rødbyhavn.
- The third contract concerns the construction of the southern section of the tunnel, i.e. the German side. The contract contains principally the same elements as the northern tunnel contract.
- Finally, the fourth contract concerns the construction of portal structures, ramps and associated land facilities. The contractor is to build the tunnel’s two portals as well as cut-and-cover tunnels on land in Germany and Denmark, respectively.
Femern A/S is tendering in accordance with the Competitive Dialogue Procedure due to the scale and complexity of the project. Several issues are identified as dialogue aspects:
- risk allocation
- work areas
- parallel works and interfaces
- labour related topics and technical topics.
The dialogue will take place as a series of meetings between the owner and each bidder with the purpose of finding creative solutions, eliminating uncertainties and improving the quality of bids with respect to dialogue aspects.
As the technical consultant to Femern A/S we expect to be greatly involved in the technical part of the dialogue, to comment and analyse various design solutions and assess their consequences.
After the dialogue phase, the contractors are to submit binding bids including specified prices. This is expected to take place in Autumn 2014. The prices from this bidding round will form the basis of the updated information on the project’s construction finances which will be submitted to the Danish Parliament in connection with drafting the Construction Act.
Contracts will not be entered into until approval has been obtained in both Denmark and Germany.
