The digital twin developed in the preceding project makes it possible to continuously record, aggregate and provide data on the course of production and the current condition of a concrete module. While the focus of the first funding period was on the life cycle phases of planning, production and quality assurance and the basic approaches of transferring the Industrie 4.0 administration shell concept to processes in the construction industry, the present follow-up project is to investigate in particular methods and concepts for life cycle-based updating and interaction of digital twins for concrete modules. The results of quality control are an essential basis for deciding whether a particular concrete module can be assembled at the intended position. On this basis, concepts and methods are developed for the case that a concrete module does not meet the quality requirements and an adjustment of the processes is necessary. The embedding of intelligent sensor technology in concrete modules offers enormous potential for digital transformation in the construction industry, all the way to data-driven business models. In order to enable sensor-based monitoring processes, e.g. of logistics, construction site assembly or structural health monitoring in the utilisation phase, a management shell-compliant data model will be created for the adaptive control of subsequent processes. The collection and evaluation of resource consumption and environmental impacts throughout the entire life cycle is also becoming increasingly important. Therefore, the component-oriented capturing of the real data necessary for a detailed LCA in addition to data from Lifecycle Inventory (LCI) databases will be explored as a hybrid approach to build a digital product memory based on the asset administration shell. Structures are usually characterised by a very long lifespan and the digital twins need to be continuously updated and made available. A concept for decentralised data management based on distributed ledger technology (DLT) is therefore being developed to better take into account the use phase with different stakeholders.
