Rhätische Bahn has awarded the tender to build the 5.86km Albula Tunnel II to a consortium led by Porr Suisse and also including Walo Bertschinger and Società Italiana per Condotte d’acqua.
The tender value of is CHF125m (£85m) and construction is set to begin in April 2015, with the tunnelling due to be finished by December 2017 and the entire project projected for completion in August 2019.
The current Albula Tunnel I is over 100 years old and overhauling it would be too expensive, as the rail services need to be maintained. Albula Tunnel I will then be converted into a safety tunnel.
“Albula Tunnel II will be built at 1,800m above sea level and is technically demanding because of the geology of the area,” said Porr CEO Karl-Heinz Strauss. “We are delighted that the Rhaetian Railway has decided to rely on the comprehensive expertise of Porr Suisse and its consortium partners.”
