The format “Helden der Baustelle” (Heroes of the construction site) shows the fascinating everyday life of the men and women on the construction site. We accompany a bridge construction engineer who has to assemble 1500 tons of heavy steel elements with millimetre precision to build one of the longest freeway bridges in Germany. We are on board a dredging vessel when a young dredger operator deepens the Elbe. And we are up close and personal when industrial climbers build a new cable car at a height of 2,328 meters – with a deadly abyss below them.
