21 Dec 2022 First underground sprint excavation of new Stockholm metro section
Works on the construction of the new “Arenastaden – Södra Hagalund” section of the Stockholm subway has entered in full activity. The project will lead to the extension of the underground transport network serving the Swedish capital city by an additional 2.5 kilometers.
As part of the ongoing collaboration between Italy and Sweden, the first underground “sprint excavation” was recently carried out at Södra Hagalund, the first of two planned stations of the new section. The operation, consisted of breaking down portions of rock through the targeted use of explosives, was completed successfully and with satisfaction of the entire team involved, because of its complexity. Meantime, the preliminary works are also underway to start excavation at the approaches to the second future station, Arenastaden.
The overall project, entirety managed by Itinera Scandinavia Filial, will see the construction of a 2.5-kilometer main tunnel, which will extend the existing Green Line of the Stockholm Metro, the associated service tunnel, two stop stations, and four descents from the surface. The works will be carried out with traditional excavation and the aid of raise boring system for ventilation shafts. They will last 53 months and have a total value of about 135 million euros.
Particular attention is being paid to reducing emissions through the use of electrical equipment, with the aim of minimizing impacts and pursuing the sustainability goals of the ASTM Group – of which Itinera is a part – in line also with the requirements.
