The Stockholm Region, through the designated entity for the extension of the metro, Förvaltning för utbyggd tunnelbana (FUT), has selected TYPSA, to provide construction supervision and coordination, together with expert support services for the Stockholm Metro Blue Line extension from Kungsträdgården to the municipality of Nacka, its branch line to Gullmarsplan intermodal station and connection to Sockenplan station. This stretch is 11 km long and affects 5 islands with a tunnel under the Bay of the Baltic Sea, with 6 new stations and a new platform under an existing station.
The work will be carried out in collaboration with the Swedish engineering consultancy Sweco. Over the last eight years, both companies have successfully developed the planning and design of the new line, providing architecture, civil works and MEP, and railway systems services, as well as the visualisation of images and dissemination of information about the new stations to be built. Under this new contract, TYPSA and Sweco will provide construction supervision and coordination, together with expert support services for stations, all mechanical and electrical installations and the metro rail systems.
“TYPSA has been working on projects in Sweden since 2014 and the award of this contract is an important milestone, as it is the first major project supervision contract for TYPSA in the country. We look forward to continuing to provide services to the Stockholm Region, contributing to the improvement of public transport in and around the city,” says Miriam Ruiz, Executive Director for Europe at TYPSA.
“We are proud to keep contributing to Stockholm’s growth and sustainable development by increasing public transport capacity. Our collective experience and our team of experts will continue to provide solutions and guidance for the expansion of the metro,” says Fredrik Lilliesköld, Regional Director at TYPSA in Sweden.
The new metro line is a technical challenge, running through a bed of rock and underwater, at an inlet of the Baltic Sea, with one of its stations located 100 m below ground level. Work began in November 2023 and is scheduled to be completed in 2030.
