A Maintenance Management Model. Upgrading and Experimentation

The paper deals with the first results of the activities of BIG Building Innovative Governance srl, Academic Spin-Off and Innovative Start Up, which provides smart services for Building Maintenance and Facility Management also launching circular R&D actions in the relative reference areas. The contribution introduces some actions actually in progress geared to upgrading the Maintenance Management Model, M3, specifically aimed at managing the life cycle of buildings. The current stage of development corresponds to a TRL 4. TRL 8 is that expected by the end of 2020. Characterized by interconnectivity and scalability, the Maintenance Management Model is a dynamic, collaborative and implementable system, whose architecture consists of three separated but strongly interconnected devices: an information interface system, a collaborative platform, a remote cloud. An ICT network infrastructure able to activate using BIM models (IFC and COBie standards) circular information workflows between all operators and/or users involved in Maintenance and Facility Management processes. It allows the development and/or implementation of information management and sharing models based on Open Data and Semantic Web. Its use will also promote shared lexicons and the circulation of knowledge within a holistic process of managing information from and for Maintenance. The use of BIM models and the possibility of collecting and managing a large amount of data will be oriented to the structuring of information feedback databases according to ISO 15686 guidelines. In this way, available information can be usefully transferred in life cycle assessments and service life prediction of materials and components.
