The Architecture, Engineering, and Construction (AEC) industry is rapidly transforming, which is caused by the increasing use and development of digital technologies. However, despite advancements in the design, engineering and construction phases, there is room for improvement, in the way assets are managed by different types of maintenance parties. Compared to the costs made during the initial design and construction phase, the operations and maintenance (O&M) costs are significantly higher, so potential advantages of new digital developments in this phase are significant. Linked Data and semantic web technologies are gaining more attention in the industry. The infrastructure sector has already recognized the benefits of linked data, with for instance the use of the Resource Description Framework (RDF) for interchanging data. However, building contractors have yet to realize the full potential of this technology for their asset management of buildings. This research aims to create a digital building logbook for a building and investigate the added value of a linked data approach for asset life cycle information management. The research will leverage historical data from an SAP maintenance management ERP database and building information from BIM models to create a graph database that integrates all asset information. In this research, a system architecture and data pipeline are proposed to integrate data from existing maintenance management and BIM systems in order to do derive new insights using two applications, which can help informed decision making in asset maintenance management. Asset managers and maintenance engineers have the ability to run complex queries that are not possible or really challenging in traditional relational databases. With a 3D user interface, also planners and technicians have access to quick insights on important data about assets and rooms. The implementation of linked data will increase efficiency, reduce costs, and improve the overall health and performance of buildings and equipment.
