BS/PAS1192 defines Building Information Modeling (BIM) to assess how well the data is structured and how extensively technology is used. It defines the evolution of the tangible asset information expression starting from paper/document-based models to data/information-based models. Digital Twin, on the other hand, is the exact reflection of reality. Each piece of the data represents an aspect of reality and vice versa. The poor data quality in Digital Twin would result in an inaccurate representation of true reality. BIM can be enhanced by adding alternate reality data (scenario data) expressing a multiverse, so-called "paradelle world." These enhancements of BIM or Digital Twin require careful planning and strong data management. This presentation will describe the steps to enhance BIM and Digital Twin, including data architecture, data integration, and data quality management. The presentation will include case studies of companies in Japan and the Asian region. Session 19E, 4:35pm - 5:35pm, July 22, 2021.
