# Developing a Building Fire Information Management System Based on 3D Object Visualization
###### Abstract  
In a building fire disaster, a variety of information on hazardous factors is crucial for emergency responders, facility managers, and rescue teams. Inadequate information management limits the accuracy and speed of fire rescue activities. Furthermore, a poor decision-making process, which is solely dependent on the experiences of emergency responders, negatively affects the fire response activities. Building information modeling (BIM) enables the sharing of locations of critical elements and key information necessary for effective decision-making on disaster prevention. However, it is non-trivial to integrate and link the relevant information generated during the life cycle of the building. In particular, the information requirements for building fires should be retrieved in the BIM software because most of them have spatial characteristics. This paper proposes a prototype system for a building's fire information management using three-dimensional (3D) visualization by deriving the relevant information required for mitigating building fire disasters. The proposed system (i.e., Building Fire Information Management System (BFIMS)) automatically provides reliable fire-related information through a computerized and systematic approach in conjunction with a BIM tool. It enables emergency responders to intuitively identify the location data of indoor facilities with its pertinent information based on 3D objects. Through scenario-based applications, the system has effectively demonstrated that it has contributed to an improvement of rapid access to relevant information. building information modeling (BIM); fire disaster; facility management 2020 10 772 10.3390/app10030772 10.  
taken after responding to a fire. However, the current fire disaster management system focuses on the performance inspection of newly constructed buildings and the temporary restoration of existing buildings alone [2]. To deal effectively with building fires, it is crucial to support and respond to fire sites accurately and rapidly in the early stages [3]. The first emergency responders, such as building managers, firefighters, rescuers, and other trained members, should be aware of all aspects of the situation to be able to analyze all information pertaining to the fire site, including the internal structures, facilities, and site-specific risk factors, and make the best decisions under the given circumstances [4]. However, the current fire response method is problematic in that the large amount of distributed information is not transmitted accurately and quickly in the event of a fire incident [2]. Rather, it is likely to transmit inaccurate information from a chaotic fire site. It is also important to collect information in a timely manner, which may prevent secondary damage and property loss [5]. Although the related information requests may be sent to the facility manager, information management in the operation and maintenance (O&M) stage is not carried out automatically. As a result, it is difficult to share information quickly, and the accuracy with which information is collected is limited owing to inconsistencies between the building drawings and the actual buildings, as well as the lack of location data for indoor facilities. Further, subjective judgment, which comprises the experiences of fire responders, is common, and deteriorates the safety of fire response activities. Therefore, first emergency responders should be provided with accurate location data of indoor spaces and facilities [6], and the related information needs to be integrated and maintained in the O&M stage to facilitate easy acquisition of the relevant information [7]. Recently, building information modeling (BIM) is widely adopted as a management tool that can share important information among project stakeholders by creating three-dimensional (3D) object models [8]. BIM is proposed as a powerful solution to integrate and link the information generated during the O&M stage to enable the sharing of important information at building fire sites.
