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."
