Architecture, Engineering, Construction and Operation (AECO) sector is characterised by a highly fragmented and scarcely interoperable framework throughout the building life cycle. Since building-related data collection and storing can be inaccurate and not coherent, facility management can be extremely complex. The use of a Digital Building Logbook, as a common repository for building information, would facilitate data availability and transparency for a variety of stakeholders involved in the construction process since most data in a paper-based format, out-of-date as-built data, or a lack of understanding about building components and systems make challenging, for example, the selection of the best refurbishment alternatives. Moreover, the heterogeneity of different sources makes fundamental the interoperability management to enable an enhanced information exchange. In this regard, the paper presents a framework for implementing the Digital Building Logbook utilising semantic web technologies. The proposed framework is built upon the use of ontologies and related data models following a federation approach, that allows the integration of data coming from different systems, using them within their domain. The result is a system that can act as a gateway for connecting different areas and data at different level of detail along the building life cycle, especially during the data-driven choices that are necessary in the operational stage.
