2.2. BIM from the point of view of asset management BIM is the information management through the built asset entire life cycle. As is known from the ISO 19650 approach, to be truly effective, the adoption of BIM must correspond to the fulfillment of specific objectives, which, in turn, define the level of information needs, i.e. the necessary and sufficient information for each objective. BIM goes far beyond being a single software application, it is the use of software tools embedded in different processes (identification of the work, data collection, decision support to the asset management system, OpenBIM approach, etc.). BIM offers value by supporting the creation, federation and exchange of shared models and corresponding structured data. While BIM development and its application to date have largely focused on the design and construction phases of assets, the most important BIM application is in the entire asset lifecycle, as a key factor for better asset management within the recognized ISO55000. As stated in "The Business Value of BIM for Infrastructure" – some of the main widely recognized BIM benefits are: • conflict reduction: thanks to interoperability and model federation, BIM reduces conflicts and changes during construction; • improvement of the quality of the project; • reduction of rework; • improved productivity. BIM keeps the needs and overall purpose of the asset in the foreground and prevents information loss when management responsibility for the asset changes. BIM tools are the technological and process successor to CAD and 2D/3D drawings that create data files of physical components and spaces. They offer an integrated work system at the company level, which produces clear and accessible information, for the management of the construction and life cycle of resources leading to significant efficiencies and an enhancement of resources. The crucial point lies in the identification of the USES and in the definition of the characteristics of the different levels of information necessary to define the detail and scope of the information that must be exchanged and provided during the life cycle of the building asset constituted, in a nutshell from the set of: • LOG - Level of Geometry - Indicates the level of geometric representation of objects; • LOI - Level of Information - Indicates the level of technical and non-geometric (alphanumeric) information of objects; • DOC - Documentation Indicates the documents and cards related to the object.
