Procurement for the Varberg tunnel, West Coast Line, Varberg-Hamra

The project´s mission is to ensure an expansion to double track in a tunnel underneath Varberg which is part of the expansion of the entire West Coast Line between Gothenburg and Lund.

The project will be realised in one contract for the planning phase with and an option for the implementation phase. The planning phase is scheduled to approximately 15 months between 2018 and 2019. The implementation period for phase 2, including restoration and demolition of the existing railway, is scheduled to take seven years between 2019 and 2025.

The contract covers approximately nine kilometres and involves the construction of tracks, bridges and other civil engineering works for both passenger and freight trains as part of a complex track traffic structure. The railway will go underneath Varberg through a tunnel roughly three kilometres in length. All passenger and freight traffic on the existing West Coast Line must be able to continue throughout the duration of the contract. Being able to maintain traffic during construction will require extensive temporary diversions.

The contract will take the form of a design and build contract with a high level of co-operation through the application of the Swedish Transport Administration's guidelines for ECI-contract (Early Contractor Involvement). The procurement process is in accordance with the provisions in the act that apply above the threshold. The procurement process takes place through a negotiated procedure by way of a two-stage process – pre-qualification and tendering.

The client estimates the total cost of the project at SEK 3,990 million as priced on 1 April 2009.
