The Priority Programme (SPP) 2388 “Hundred Plus” aims to substantially extend the service life of infrastructure through advanced maintenance strategies. Phase 1 emphasized the automated collection of structural data, the generation of precise 3D models, and the integration of real-time monitoring data into digital twins for continuous structural assessment. These foundational efforts enable early damage detection and the formulation of proactive maintenance measures. Building on the findings from Phase 1, the research in Phase 2 will focus on the development of condition indicators and of predictive models to enable more accurate and holistic structural condition assessments and the prediction of the structural service life. Moreover, methods for deriving specific handling recommendations will be developed to support predictive and prescriptive maintenance approaches. These methodologies will be validated on real-world structures such as the Nibelungen Bridge in Worms, which is the validation building of the SPP 2388, and e.g. the “openLab” bridge in Bautzen.The Coordination Project has essential role in fostering interdisciplinary collaboration and network building. It facilitates national and international cross-disciplinary networking among researchers within and beyond the SPP, supports early-career researchers, and implements targeted measures to promote gender equity. Furthermore, the dissemination of findings to both professional audiences and the public will be prioritized, to raise awareness of the relevance of the topic throughout society and increase the visibility of the SPP. The focus of the accompanying scientific research in the Coordination Project is on the integration of Structural Health Monitoring (SHM) systems developed across both phases into a collaborative framework, taking into account data quality and uncertainty. The data platforms will be further enhanced to improve system interoperability, incorporate automated metadata management, and ensure high data quality. Additionally, an intelligent knowledge management strategy will systematically organize structural records and monitoring data, ensuring their accessibility and utility. The Nibelungen Bridge as the central demonstrator provides a robust platform for the validation and practical application of the developed methodologies. These methods can be transferred to other engineering structures, thereby laying the foundation for sustainable advancements in infrastructure maintenance practices in the future.
