The VARIOKIT tunnel formwork solution accelerated construction of the 228 m long Marchlehner gallery situated at a height of 1,800 m above sea level. The competent planning process took into account al possible project requirements which ensured on-schedule completion before the onset of winter.
The PERI formwork concept consisted of a 13.50 m long slab formwork carriage with a 3.00 m width – the 4.50 m high drive-through height provided easy access for construction site vehicles as well as transit traffic.
A transverse launching unit integrated in the lifting unit ensured problem-free alignment of the formwork carriage to match the changing radii.
The four formwork units for the valley-side 1.50 m cantilevered tunnel slab were likewise based on VARIOKIT system components and could easily be moved by crane using designated lifting points on the gallows construction.
Two standard cycles each 12 m long were formed, reinforced and concreted per week.

Together with the PERI engineers, we designed a customized formwork carriage solution. This allowed us to concrete two sections per week – and, in spite of the ever-present passage of transit vehicles and steep longitudinal inclination, on-time completion was guaranteed. Due to the lightweight construction and hydraulic operations, the carriage could be lowered, moved forward and set up for the next cycle in less than 60 minutes.
