The contract for constructing the 2.2-kilometer-long Altona noise protection tunnel on the A7 motorway in Hamburg, has been granted to Implenia and HOCHTIEF. The awarded budget for this contract is about EUR 580 million. While, the commercial part of this project is up to Implenia, HOCHTIEF leads the technical part of the project as part of a joint venture.
The development of the motorway to eight lanes between the Hamburg-Othmarschen and Hamburg-Volkspark connections, will cause blocking the gap between the current A7 expansion projects north and south of the Elbtunnel. The near areas of Othmarschen and Bahrenfeld will be reconnected by the top of the 2,230-meter Altona noise protection tunnel, which will be covered with allotments, greenery and parks.
The commencement date of this eight-year project is April 2021. The client is, DEGES (Deutsche Einheit Fernstrassenplanungs und -bau GmbH), the project management company that plans and builds highways for its owners – the federal government and twelve federal states. The considered value, for the commercial lead of the project, which is Implenia’s duty, is a net total of around EUR 580 million. Moreover, 35% of the total contract volume belongs to Implenia.
Cooperation for progressing the urban transport foundation
The project will cause a significant effect on the renewal and improvement of infrastructure on one of Germany’s major traffic arteries. In addition, due to general noise protection measures, inhabitant’s life quality will be boosted, as well as everyone in Hamburg who can enjoy the new green space in future.
Christian Späth, Head Division Civil Engineering at Implenia states: “We were able to identify numerous optimization opportunities during the tendering process, which began in November 2019. This allowed us, among other things, to bring forward parts of the detailed design work and systematically incorporate the results of more than 30 coordination meetings into the project calculations. This meant we could significantly reduce the project risks for everyone involved and create a good basis for working together for the next eight years until the project reaches a successful conclusion.”
