Implenia wins contract for connecting tunnel to metro depot in Stockholm | large, complex and sustainable infrastructure project | expertise in tunnelling and concrete works | total contract volume of around CHF 98 Mio.

Glattpark (Opfikon), 3 June 2022 – Region Stockholm, Förvaltning för utbyggd tunnelbana – the state-owned company responsible for Stockholm’s subway infrastructure, awarded Implenia the contract to build the connecting tunnel to the expanded metro depot in Stockholm, Högdalen. The total contract volume amounts to SEK 1 billion, around CHF 98 Mio.

Connecting tracks to Farstagrenen and parking area
The project consists of building the required infrastructure to connect the expanded depot to the existing metro track Farstagrenen. A new concrete tunnel and trough will be planned and built at the connection point to Farstagrenen. The rock tunnel consists of approximately 2’000 m of track tunnel and a 500 m long underground parking area for trains. The tunnel is being built in a densely populated urban area and close to other railway tracks using blasting technology. Implenia will also equip the tunnel with the required installations for electrical and telecommunication systems, control systems, ventilation and fire sprinklers.

Large, complex and sustainable infrastructure project in line with Implenia’s strategy
“We are very proud of being chosen for this large, complex and multidisciplinary infrastructure project, fully in line with our strategy, and thank our client Region Stockholm, Förvaltning för utbyggd tunnelbana for their trust in Implenia. We are looking forward to a fruitful collaboration on the project and are glad to bring in our longstanding tunnelling expertise as well as our skills in project management and sustainability,” says Christian Späth, Head Division Civil Engineering and member of the Implenia Executive Committee.

Implenia will plan and build the tunnel according to CEEQUAL sustainability standards, one of the client’s requirements. Planning and realization will be based on a BIM model (building information modeling) and delivered using the Lean Construction method.
