All over the world, private and freight traffic will continue to increase. According to the German Federal Statistical Office, even now more than half of all people live in cities and the surrounding areas. Globalisation and urbanisation are causing these infrastructure developments. As a result, people, raw materials and goods are being moved around more than ever before. Civil engineering is confronted with increasing demands; this includes structures for transport and utility networks. Tunnels and bridges are key elements. Such projects are normally tendered internationally. For business reasons, the bidding companies must be able to use reliable and exactly definable construction machines or formwork and scaffolding systems.
After about 9 km each through tough gneiss, on September 11, 2018 the tunnel boring machines “Queen Eufemia” and “Queen Ellisiv” achieved a double breakthrough near the city center of Oslo. The Follo Line Project is currently Norway‘s largest infrastructure project and involves the construction of the country‘s longest railway tunnel. The two 20 km long tunnels connect Oslo with Ski further to the south. From 2021 they will shorten travel time for commuters by half.
The 100-year old, two-track Rudersdorf Tunnel between Siegen and Haiger restricts the route’s capacity owing to its small cross-section. Furthermore, the rail tunnel is requiring ever increasing maintenance. In a process lasting only seven months, a feasibility study was produced for the project, featuring six alternatives involving a more fundamental pre-planning process for the preferred option 3b “Construction of two new single-track tunnel tubes to the west of the existing tunnel including its decomissioning”. It has since passed the DB Netz AG’s “stress test”.
