The Filder Tunnel (Plan Approval Section/PFA 1.2) and the tunnels running to Ober-/Untertürkheim (PFA 1.6a) for the Stuttgart–Ulm rail project are being built by the ATCOST21 JV on behalf of the DB Stuttgart–Ulm GmbH. The Filder Tunnel’s two tubes will link Stuttgart’s new Central Station with the Filder Plain to the south of Stuttgart. The tunnels leading to Ober-/Untertürkheim connect the Central Station with the existing rail line in the Neckar Valley and the new railway yard at Untertürkheim. The article in tunnel 5/2018 provides an overview of the status of the works as well a preview of forthcoming construction measures.
In the border region between Switzerland and Austria, the largest hydroelectric run off river power station in the Alps, is being built in Engadine and in Tyrol on the upper reaches of the river Inn.

This article from tunnel 5/2018 was part of the conference programme at the Swiss Tunnel Congress 2018.

Interview with Dr.-Ing. E.h. Martin and Martin-Devid Herrenknecht
Herrenknecht AG is a globally successful family business with 5000 employees and the market leader, not only for tunnel boring machines. Since the founding of Herrenknecht GmbH in 1977 by – as described aptly in the company chronicle – “namesake, driving force and CEO” Dr.-Ing. E. h. Martin Herrenknecht, the company has developed dynamically and convinced again and again with technically sophisticated solutions to problems in underground construction. Meanwhile, Martin-Devid Herrenknecht, engineer and one of three children, has joined the company. Rarely does one have the opportunity to meet both father and son for a very personal interview with fascinating statements on the market, technologies and the future of tunnel construction.
