For the five piers of the bridge in a horizontal position, 30 drilled piles with depths of over 30 meters were required, for which the largest rotary drilling rig in Austria with a weight of 180 tons was used in 2022. In the autumn, the five foundations were then concreted, upon which the heavy piers were subsequently erected. For the construction of these piers, which can reach heights of up to 40 meters, the Framed formwork Framax Xlife the Climbing formwork MF240 were used, each of which was set up using cranes.
After the completion of the piers, the so-called hammerheads, which serve as starting points for the cantilever construction method, were concreted on top of them. In this construction method, Doka cantilever forming travellers are used, combining planning and cost certainty with an optimal construction process. The perfect coordination between support structures and formwork, the high safety standards, and the optimized ergonomics ensured swift and secure progress in construction. This allows the subsequent construction sections to be added in parallel to the freely protruding ends of the hammerheads.
"The limited length of the hammerheads present a challenge, as a result of which the two cantilever forming travellers could not be placed one after another or side by side," explains Markus Stastny, Technical Manager at Doka Austria. His team had the so-called "fork solution" ready as a response. "This made it possible to place the traveller interlaced inside each other at the same time and very few conversion work of the Cantilever forming traveller planned via DokaCAD for Revit was required," says Stastny. Starting in March 2023, the bridge structure was constructed horizontally, starting from the hammerheads, in symmetrical 5-meter sections.
