For the supply of all special formwork (such as formwork for the widening, connecting structures, cross-passages and the access of the Prague intermediate access), the JV Tunnel Feuerbach (Baresel Tunnelbau GmbH, Kunz Untertagebau GmbH and Bertschinger Bau GmbH under the project management of Johann Bachsleitner) selected the specialist Huber & Sohn, Germany. The systems, manufactured in carpentry-style timber construction, were delivered in ready-to-use modular units. Alkus GM6 formwork panels were used as formwork facing. A technical article on this project will be published in tunnel 4/2022.
