Customised processes support bridge renovation in Chur
The AS Chur Süd consortium has commissioned STRABAG to replace the bridge edge beams of the Sommerau subway in Chur. The timber construction team from the Schlieren-based construction company developed a customised solution for the tight space conditions.
The AS Chur Süd consortium, consisting of METTLER PRADER AG and Cellere Bau AG, has commissioned STRABAG to replace the bridge edge beams as part of the renovation of the Sommerau subway in Chur. The timber construction department of the Schlieren-based construction company was tasked with developing a customised method for the formwork, explained STRABAG in a press release. “With our experience, we found the right solution,” Dominic Graf, timber construction foreman at STRABAG AG, is quoted as saying.
Specifically, the work was made more difficult by the limited space available, which, among other things, did not allow for a conventional substructure for the formwork. The STRABAG timber construction team solved this problem by reinforcing the formwork panels with flat steel. Fire hoses were inserted into the gaps. The hoses, filled with compressed air, hold the panels in a stable position during concreting.
According to the press release, the first bridge edges have now been completed to the complete satisfaction of the master builders on site. According to STRABAG, the other construction phases are currently being realised according to plan with the help of this technically demanding but ideally suited solution.
