    Implenia starts work on the tunnel in Hamburg

    Construction work on Hamburg's district heating tunnel began on August 5, Implenia announced in a statement . The construction and real estate company from Opfikon is realizing the project on behalf of Wärme Hamburg . The 1.16 kilometer long tunnel will cross the Elbe about 2 kilometers west of the Elbe tunnel for the autobahn.

    From the winter of 2024/25, this will be used to transport waste heat from industrial processes in the south to the north of the Hanseatic city. This is a requirement so that the coal-fired power plant in Wedel can be replaced by energy from the future Hafen Energy Park of Hamburger Energiewerke GmbH . "We are pleased that we can plan and implement this large and complex infrastructure project for the Hamburger Energiewerke and thus contribute to a sustainable energy supply in Hamburg," said Thomas Fiest, Head of Tunneling Germany at Implenia.

    In the first construction phase, Implenia is constructing the start and target shaft with diaphragm walls 1.5 meters thick and 30 meters deep. Then a tunnel boring machine will bore the actual tunnel with a diameter of 4.55 meters. Access and operating equipment for the operation should be accommodated in the shafts.

    Implenia will build a 1.2 kilometer long tunnel for Wärme Hamburg , the construction and real estate company from Opfikon informs in a press release . The tunnel is to connect the north of Hamburg to a new heating network. To do this, it will cross under the Elbe around 2 kilometers west of the Elbe tunnel for the motorway.

    The work is divided into two phases, with the planning phase starting in October. Implenia has now received the order for further planning and construction work from the beginning of 2022, according to the announcement. The total order volume there is estimated at around 75 million francs.

    The work should be completed by the first quarter of 2025. To this end, Implenia will first create diaphragm walls for the start and finish shafts with a depth of up to 42 meters. A tunnel measuring 1.16 kilometers long and around 4.5 meters in diameter is then to be drilled between them and lined with precast concrete elements. Implenia is also responsible for planning and installing the operating technology for the district heating pipeline.

    "We are very pleased that we are able to create this large and complex infrastructure project for our customer Wärme Hamburg", Erwin Scherer, Head of Tunneling at Implenia, is quoted in the press release. "The fact that we are making a contribution to improving the sustainability of heat generation gives us additional motivation, because sustainability is an Implenia corporate value that we will also live by in this project."
