Implenia, in a joint venture with Hochtief, has won the €90M (£81.2M) contract to build the Anneberg-Skanstull tunnel in Stockholm.
The 14km Anneberg-Skanstull tunnel will help improve electricity supply in the Greater Stockholm region, by connecting the north and the south of the city with a new electricity supply.
The 5m diameter tunnel will be bored by TBM between 50m and 100m below Stockholm and includes six ventilation shafts, elevator systems and the construction of technical buildings for electrical equipment near Anneberg and around the shafts.
“Winning this order underlines our expertise in challenging infrastructure construction and our excellent local foothold. Together with our partner Hochtief, we will soon be embarking on the realisation of this milestone in electricity infrastructure”, said Implenia head of business unit infrastructure René Kotacka
Completion is scheduled for 2024.
