The Nibelungen bridge as a pilot project for digitally assisted structural maintenance The construction industry is one of the main consumers of natural resources and contributes significantly to CO2 emissions in Germany with an annual waste volume of 54 %. Therefore, the preservation of existing buildings can make a significant contribution to environmental protection and resource conservation. However, effective monitoring and maintenance concepts are needed to extend the service life of structures while maintaining their stability and functionality. This paper deals with a pilot project in which the Nibelungen Bridge Worms serves as a validation object to develop a new, digitally supported maintenance strategy. First, the bridge and its maintenance history will be presented. Subsequently, the pilot project is put into the context of the DFG priority programme SPP 2388 "Hundert plus". Afterwards, the specific key aspects including geometric modelling, structural health monitoring (SHM), digital twinning, level 4 recalculation and the assessment of detected structural damages are described. Finally, conclusions and outlooks are given. [ABSTRACT FROM AUTHOR]
