Tunnel construction

Railway and road tunnels not only shorten distances but also make alpine zones more attractive as a habitat for humans and animals. Shifting traffic underground conserves natural resources and prevents noise development. In growing urban areas, underground tunnels guarantee environmentally friendly and efficient mobility. As a pioneer in both road construction and railway construction, SWIETELSKY recognised the potential of tunnel construction early on. By participating in important infrastructure projects, the company was able to make its mark, becoming a leading specialist in this field as well. What distinguishes SWIETELSKY from its competitors is its decades of experience in dealing with geological specificities, its skill in applying high-tech machines and processes, and its planners’ engineering know-how.

Current lighthouse project

POWER STATION, Tauernmoos, Austria

The Tauernmoossee reservoir in the Hohe Tauern National Park has been used by ÖBB (Austrian Federal Railways) for power generation since 1929 together with the Enzingerboden power station and is now being modernised from the ground up. The new pumped storage power plant aims to utilise the existing Weißsee pre-storage reservoir as a storage basin for the flexible coverage of energy demand. SWIETELSKY tunnel construction is responsible for the implementation of this major project: more than ten kilometres of tunnels are being bored through the rock. The underground pressure tunnel between Weißsee and Tauernmoossee will be 1.6 kilometres in length, partly steel-armoured: eighty cubic metres of water per second will be carried to the actual heart of the system, a power plant hidden in a cavern. Completion is scheduled in 2025.
