The bidding consortium H41 Sill Gorge-Pfons comprising the companies Implenia Österreich GmbH, Implenia Schweiz AG, Webuild S.p.A with its Swiss subsidiary, CSC costruzioni SA secured the EUR651 million contract for Lot H41 Gola del Sill-Pfons of the Brenner Base Tunnel project .   

The Lot H41 is a section of the Brenner Base Tunnel in Austria and consists of the construction of the railway from Gola del Sill near the city of Innsbruck in the north to the town of Pfons located further south. The contract includes both the traditional method of excavation for the two parallel tunnels for approximately 7.3 km, including auxiliary tunnels as well as the mechanised method of excavation for another 16.5 km, in addition to the lining of the walls of completed tunnels, an underground emergency stop at Innsbruck, access tunnels, exploratory tunnels and parts of other secondary tunnels.  

The mechanised method will deploy two TBMs (10 m diameter). The design of the project focuses on the environmental sustainability of the project during construction: the logistics of the work sites are designed to reduce travel times for the transport of materials, and measures to reduce dust and noise are foreseen.  

The Brenner Base Tunnel will be crucial for Europe. It will be a key part of the Scandinavian-Mediterranean Corridor of the Trans-European Transport Network (TEN-T) that will connect Helsinki in Finland and La Valletta in Malta. It also plays an important role in connecting Italy and Austria with a high-speed/high-capacity railway.
