Hochtief has been awarded the a €132m (£105m) contract to construct a 22km tunnel for the Gemeinschaftskraftwerk Inn hydroelectric power station on the River Inn in Austria.
The Triebwasserweg Maria Stein tunnel is scheduled for completion in mid-2018. The construction lot comprises driving of a more than 22-kilometer-long pressure tunnel and is the biggest and most significant one of the three construction lots of the hydroelectric power station on the River Inn.
Wilfried Rammler, General Manager of HOCHTIEF Infrastructure commented:
"We are happy to have won another large-scale contract in the Austrian market. This underscores our competence in the construction of sustainable energy infrastructure in Europe."
The 22.6 kilometer, 6.5 meters diameter pressure tunnel will run underground from the reservoir in Ovella to the powerhouse in Prutz.
Hochtief will drive the pressure tunnel with two hard rock double-shield tunnel boring machines.
In future, the water will be channeled through the tunnel to the powerhouse in Prutz where, once the structure is completed, environmentally friendly electrical power will be generated for more than 100,000 households.
The German Group's UK subsidiary Hochtief (UK) Construction Ltd is based in Swindon.
