The BIM Execution Plan (BEP) or Information Management Plan (IMP) is an essential document, drafted to define the framework for managing the construction project and optimizing the workflow. The BEP is the result of two successive steps: the first pre-contractual, the second during the contractual execution phase.
The Italian standard UNI11337:2017 defines the same document in the Information Management Plan. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The focus in this case is no longer on the characteristics of the object but on the information the object must contain to satisfy the professional’s needs at that precise moment in the design process.
The LOIN concept stems from the understanding that the level of
depth of a model is not an absolute parameter but must be assessed based on various conditions, introducing the concept of information granularity.
e.g. A wall composed of layers but delivered in a single package is not fully readable and thus has a low granularity of information.
Conversely, a layered wall identifiable in each of its component parts will have a high granularity of information.
The level of granularity is linked to the need (Information Need), therefore it must be calibrated according to the needs, according to three categories of information:

This term refers to the set of operators, products, and services related to the real estate market. The real estate sector is commonly divided into three main segments based on the type of activities performed. <\/p>

The first segment concerns the initial phase of a real estate project (r.e. development), which ranges from the feasibility assessment of the investment, to the identification of the building area, to the management of relationships with public administrations and credit institutions, up to the construction of the property. <\/p>

The second category encompasses all real estate management activities (e.g., real estate management), including: ordinary and extraordinary maintenance of the property (building management); management of cleaning, concierge, internal security, and general services related to the needs of property users (facility management); and management of financial and administrative relationships, such as rent collection, insurance payments, accounting, etc., on behalf of the owner (property management). <\/p>

The third segment, finally, concerns the professional management of real estate assets (asset management) aimed at enhancing and optimizing their profitability through purchase, sale, divestment, restructuring, or reconversion transactions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
