A12 Senftenberg Gallery Refurbishment

Austria

In a first, Doka is fielding a formwork traveller with a face-sheet made of steel panels to produce a new inner shell for the twin-tube Senftenberg Gallery. Following 36 casting sections in the1st tube and a break to accommodate winter tourist travel, the same forming traveller can be re-used for the 2nd tube with only minor modification.
