How pre-assembly on the ground can prevent accidents from falling was demonstrated at the action area "With a cool head to the top".
There, BG BAU (statutory construction insurance), together with the partners ZVDH (Central Association of German Roofing Constractors) and Holzbau Deutschland (Association of German Master Carpenters), will show how safe working works - from the prefabrication of the roof elements on the assembly table to placing them on the house with the help of the crane.
