Die Digitalisierung zählt zu den wichtigsten Veränderungsprozessen in diesem Jahrhundert und betrifft alle Bereiche unserer Gesellschaft. Im Bereich des Bauingenieurwesens bietet die Digitalisierung viele Potenziale für alle Phasen des Lebenszyklus von Bauwerken, die durch Verfügbarmachung von Daten und die Definition neuer Wege der Zusammenarbeit ausgebaut werden können. Digitale Methoden, insbesondere Building Information Modeling (BIM) und Structural Health Monitoring (SHM), bieten für Ingenieurbauwerke der Infrastruktur hervorragende Ansätze, diesem Gedanken gerecht zu werden und können einen Beitrag leisten, den Bauwerksbetrieb effizienter zu gestalten. Der Prozess der Bauwerksprüfung von Infrastrukturbauwerken folgt heute festgelegten Regelinspektionsfristen. Mithilfe des vorgestellten Konzepts soll durch die Verzahnung von BIM und SHM eine digital gestützte Instandhaltung von Eisenbahnbrücken entwickelt werden, um ein prädiktives Instandhaltungsmanagement zu ermöglichen und damit die Zuverlässigkeit von Ingenieurbauwerken über die Lebensdauer hinweg zu verbessern. Im Rahmen der Konzeptentwicklung werden die erforderlichen Methoden und Prozesse definiert, erklärt und harmonisiert.

To ensure intact infrastructure systems and a long service life of bridge structures in the operational phase, the establishment of a predictive maintenance management based on digital 3D models is essential. These 3D models are often not provided, especially for existing bridge structures. In addition, their creation is very complex, resource-intensive and involves many stakeholders. Through the use of digital methods and technologies, important efficiency steps have been taken in the creation of digital models in recent years. Although semi-automated modeling of digital bridge models is possible, the quality agreed upon is not always achieved at the end of each development step. In this article, an approach is developed to create transparency, safety, consistency and traceability for the generation process of digital models of existing bridge structures. The approach involves all stakeholders participating in the process and creates a decentralized control and documentation mechanism using distributed ledger technology (DLT) and blockchain. First, the current status on the use of DLT in the construction industry and bridge engineering is presented. Then, the system concept is presented and the basic algorithm is described. The general system architecture and the workflow are presented and described in models. Then the basic feasibility of the approach is presented and the previously shown concept is implemented. The basic functions of the algorithm are described and the results are critically reviewed. The result of the article is showing the possibilities to use DLT and blockchain to improve the accuracy, transparency and security in the creation of digital models of existing bridge structures.

There are about 65,000 bridge structures in the infrastructure network of the Federal Republic of Germany. Due to the long operating phase of bridges, they have an influence on sustainability. To evaluate the sustainability of bridges in the operational phase, digital building models can serve as a consistent and structured database to increase the efficiency and transparency.In this article, an innovative evaluation system for measuring and assessing the sustainability of a bridge structure in the operational phase based on a digital bridge twin is developed. First, the workflow is presented in a process model and the necessary requirements for the digital twin of the bridge structure are defined. In addition, the semi‐automatic sustainability assessment system is described and the linkage via an interoperable interface to the digital twin is designed. The approach is tested and validated using a real demonstrator. The result of the paper shows an approach to use digital twins for a novel and semi‐automatic sustainability assessment in the operation of bridge structures.
