This article presents first results of a generalized workflow for harmonized data integration and transformation of building and environmental data in the context of a smart industrial campus. The strategies presented aim to improve the ‘situational awareness’ (the knowledge of the current situation in industrial sites). This with the aim of enhancing new Industrie 4.0 opportunities with current state information. In this context, the merging, linking and sustainable organization of the entire industrial campus into a 4D spatial data infrastructure (SDI) – e. g. buildings and halls, assets and their IoT-sensors – plays an essential role. In this article, we present first results of the WISS 2025 research project ‘aWHEREness:lab’ for the conceptualization, modeling and communication of a 4D industrial campus SDI.
