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”.

An extensive subway network is being built in Doha, Qatar. Part of this network is the so-called Green Line, for which also a number of underground street crossings had to be constructed. Originally, it was planned to carry out construction of these underpasses by means of the cut and cover method. Following a proposal of the contractors, three underpasses were, however, constructed by the mining method. Design and construction were executed on the basis of the AJRM-Method.
