###### Abstract
They transform this information into representations of physical locations that are comprehensible and intelligible to the final user [5]. Figure 1: Schematic view of an indoor positioning system (IPS) system and the role of enterprise building information modeling (EBIM) in St. Olavs Hospital. The Internet of Things (IoT) can be used to streamline the hospital performance. Using location systems makes it easier to keep track of where different types of equipment are located. In this regard, EBIM is a virtual representation of the building stock and is a process-driven approach with a holistic business perspective. Healthcare managers are continuously dealing with subjects that are related to the safety of their amenities, the contentedness of their employees, the quality enhancement and improvement of the standard grade of care provided to their patients, the pricey workflow and the inefficiencies of costly processes that affect their bottom line. Many a time, information technology (IT) innovations for the healthcare system are listed as potential tools for improvement. Pioneers and researchers are constantly working to make new technologies that could support business operations and enhance the quality of activities. Today's healthcare facilities are faced with the augmentation of patient numbers as well as higher expectations for patient experiences and the level of satisfaction as an important outcome of healthcare services. To meet these rising requirements, eliminating the wasted steps and making a simpler workflow is a necessity. One of the main components to achieve an efficient workflow is asset tracking and management. When employees are under duress, they do not have enough time to find medical equipment such as IV pumps and patient-monitoring devices. Hence, IPS is one of the more recent and effective ways of addressing these challenges, such as integrating real-time location systems (RTLS) into hospital processes [6]. Accordingly, to pinpoint the device's location and users inside the building, small devices, such as beacons, act as sensors or hot spots supported by Bluetooth low-energy (BLE) wireless technology. Depending on the system in which they are applied, beacons are active or passive devices which send out a single signal that is interpreted by other devices to facilitate distance identification. The sensors provide extremely accurate locational tracking [5]. This paper presents a study related to indoor positioning systems (IPS), which is a development in the field of smart facility management based on enterprise BIM (EBIM). By considering BIM as a model of digital interaction for different types of properties through all stages, where everyone can initially share and visualize through different digital interfaces, the focus is changed greatly from project-centric to see BIM in a business perspective. In this regard, St. Olavs Hospital, together with the Central Norway Regional Health Authority (HMN) initiated a project entitled Life-Cycle BIM based on facility management. The concept of this is called enterprise BIM (EBIM or business BIM), and its main emphasis is on integration, information sharing and openness across business structures. In fact, this is the most important originality and innovative aspect of this study. EBIM is a concept that obeys and follows the strategy of the OpenBIM [7] standard during a building's life cycle, and it aims to optimize and improve business management, knowledge sharing, digital interaction and connection in the different phases of the projects. For this purpose, this study is focused on a tracking system at St. Olavs Hospital as a case study and reviews the necessity of a survey system based on the wireless field that is recognized in the course of a real process of establishing a spatial management system for large facilities. Accordingly, the ultimate goal is to develop the management system based on devices that can collect up-to-date data in large building complexes for facility management purposes.
