3. The site
Early 2012 the construction of the bridge infrastructure began. The piles, the foundation slabs
and the elevations were built.
An indirect foundation made of bored piles, with the concrete class C25/30 was adopt-
ed, suitable for integral bridges. One pile beneath each foundation plate includes 3 tubes for
the sonic tests (“Fig. 13”). The piles are 8 m, 10 m and 12 m long according to the geological
necessities.

In spring 2012 the concrete foundations of class C30/37 were poured. The outgoing
reinforcement ensures the connection to the infrastructure elevations (“Fig. 14”).

As a next step the elevations, abutments and piers were built (“Fig. 15”, “Fig. 16”,
“Fig. 17”). To ensure the connection to the superstructure, thus underlining the integral
character of the structure, reinforcement bars reach out from the concrete joints.
