OHLA increases its presence in the Swedish rail infrastructure sector with a new contract for the expansion of the Stockholm metro network. The project, awarded by Region Stockholm for nearly 85 million euros, makes OHLA the leading contractor for the expansion of the metro in the Swedish capital with a combined contracts value of 238 million euros. This initiative will benefit more than 300.000 users who use this sustainable transport method on a daily basis.

The new contract Sockenplan stage 2 and Slakthusområdet, includes the execution of 1 200 m of a new metro line including two tracks and one service tunnel with a total length of 1 736 m, as well as the construction of a new metro station, Slakthusområdet, with a depth of 50 meters below surface and including a concourse, ventilation shafts, containment structures and a 310-meter cut and cover concrete tunnel.

With this project, OHLA has been awarded its third contract with the Region of Stockholm for the extension of the subway system within the Blue Line. The first contract in Kungsträdgården, includes the construction of two single-track tunnels and a service tunnel, as well as cross tunnels, with a total length of approximately 4,500 meters. Adjacent to the new project is Gullmarsplan, including the construction of two line tunnels and a service tunnel with a total length of 3,100 meters, as well as a 300 m long subway station at a depth of almost 70 meters below the existing Gullmarsplan transport interchange which is the third busiest station of the country.

Sustainable construction

Ceequal certification system is used, at a level that at least corresponds to “Very Good”, to be able to measure the sustainability performance of the project, being an integral part of design and production.

The project uses BIM as driving tool for general coordination and clash detection, integrating all design requirements for future installation elements such as lifts, escalators and electromechanical systems.

The new station, in close proximity to major sport and cultural venues such as Avicii Arena, Hovet and Tele 2 Arena, becoming an important connectivity point and boosting Stockholm’s sustainable transport. It will also have several access to ensure a controlled flow of travelers when major events are held in Slakthusområdet, an emerging urban district located in the former industrial area south of Gullmarsplan, Stockholm.

Present in the Swedish market since 2017

OHLA entered the Swedish market in 2017 with the award in consortium of the project to enhance the existing railway line between Lund and Arlöv (Malmö) for 295 million euros, considered the main railway communication route through which the traffic of the Scandinavian peninsula runs with the rest of the European continent. Subsequently, the company was awarded the extension of the railway section between Lund and Flackarp, in Skane, which is part of the same railroad line.
