Tunnel bypass Flüelen, Switzerland - The special support und moving construction comprised of elements from the PERI tunnel waler system which adapted exactly to each cross-section. The complete formwork unit could be moved on rails from section to section using pulling equipment supplied by the contractors. Due to economic reasons, setting and stripping were done mechanically.
