“…The article presents the development and validation of a sustainability assessment of bridge structures in the operational phase based on digital twins. Due to the high importance of bridge structures for society and economy [7] and the long operating phase of several decades [14,38], the creation as well as evaluation of constant positive sustainability is of significance. For this purpose, the use of a digital twin as a database and current representation of the physical object as a digital image is essential.…”

“…In this way, factors such as energy efficiency, environmental impact, cost, user satisfaction, technical and process quality can be taken into account and the performance of the building can be monitored throughout its life cycle. In the operational phase of bridge structures, a digital model also serves as a data basis for the entire life cycle of the infrastructure [7,8]. To ensure that bridge structures, which are important for the economy and society [8,9], can be sustainably managed and maintained in their long operating phase over several decades in the future, it is necessary to establish an optimized assessment system [10].…”

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.

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.

“…Bridge structures have a special significance for the economy and society for Germany and Europe. (Hartung et al, 2019) At the same time, the provision of resilient infrastructure is a challenging task with multidimensional complexity. (Klemt-Albert et al, 2018) Especially due to the long operating phase of bridges, the maintenance of bridge structures is of particular importance.…”

“…In this way, the service life of bridges can be increased in the long term. (Hartung et al, 2019) In order for the existing potentials to be experienced through the implementation of disruptive technologies for the maintenance of bridge structures, a reorientation of existing processes is required. For example, the use and linking of digital models, robotic systems, and artificial intelligence (AI) in the area of damage management can increase process efficiency and raise the level of automation.…”

Despite the optimization of maintenance processes through digitalization, the inspection processes of bridges to determine damages are still analog. At the same time, damage data records are not organized and in a transparent and consistent manner so that all project participants can access and exchange the data interoperable. By combining innovative technologies and using open data exchange formats, this paper presents an approach that further optimizes and automates the process chain for damage management in the maintenance of bridge structures. In this context, a Cloud Computing system (CCS) serves as a central data hub for comprehensive and consistent storage and management of damage related data. A Common Data Environment (CDE) with an integrated digital building model, a damage library and an artificial intelligence (AI) module are implemented in the CSS. The concept exclusively uses open exchange formats to further integrate all project participants while improving collaboration in the maintenance phase and ensuring interoperability. In addition, robotics and artificial intelligence are used to automate the process chain of damage capturing and evaluation. In this paper, the above aspects are highlighted and a concept for an automated damage management for the maintenance phase of bridge structures using walking robots and digital models is developed and realized as a mock-up.
