In the Precast Components 2.0 project (PCC 2.0), new real-digital process chains are being developed to extract concrete components from existing buildings that are to be demolished, which can then be refurbished and reused as "precast components" for new buildings. While digital-real process chains of new buildings usually start with digital planning before they are realized on the construction site, a real-digital process chain starts with an existing building.
The basis of this novel real-digital process is a digitization platform for acquisition, planning, management, logistics and manufacturing, which is being developed as a prototype. The real-digital process chain is then implemented in the construction of a life-size demonstrator in the form of a building section made up of refurbished PCC 2.0 elements.
The aim of the project is to developed a directly applicable, real-digital process chain which is realized by an intelligent linking of existing digital recording, planning, production and data management technologies. It was achieved with the help of digital tools such as 3D scans and the creation of "digital twins" as well as experimental and theoretical investigations.
