For several years, there has been an intensification of using BIM (Building Information Modeling) technology in the design and construction phases of building projects. However, it is rare to come across data regarding the implementation and subsequent verification of the utilization of BIM's capabilities in the longest phase of a building's life cycle - the operational phase. Currently, various property management systems and methods are applied during the operational phase of volumetric construction. However, these are often systems dedicated to specific types of activities (e.g., invoicing, electronic documentation approval), often requiring a significant amount of manual work. Additionally, current practices do not integrate the systems in use, and manual processing results in the manager receiving scattered and unformatted data that is difficult to use in daily operations. The aim of this article is to present the potential benefits of implementing BIM technology during the operational phase of a facility. The article outlines the possibilities of using the information introduced into the BIM model during the operational phase of a building. It also presents a proposed approach for creating a BIM model for the operational phase. In a subsequent article, the authors will focus on presenting an example of its implementation.
