## 1 Introduction
In collaboration with the Atlanta Fire Rescue Department, [PERSON] et al. [16] developed the Firebird framework to help municipal fire departments identify and prioritize fire inspections for commercial properties by using machine learning, geocoding, and information visualization. [PERSON] et al. [17] conducted inductive analysis and a survey questionnaire to discuss the integration of inspection and reporting systems for fire safety equipment and public building security. This study attempted to clarify the ambiguity between firefighting and building safety and to provide initial results to support amendments to related laws and regulations. Existing research related to fire inspection does not consider continuous compliance to fire codes. Fire inspections are usually scheduled periodically (for example, on an annual basis). On one hand, good inspection programs require a significant amount of investment in human resources to conduct the inspection, and the inspectors are presumed to know the myriad code requirements, procedures, and processes. In reality, fire inspection programs may be inadequately staffed, may not be supported with a strong enough level of commitment by the local authority, or simply may not exist. On the other hand, some items require inspection at more frequent intervals because of the dynamic features of their status. For example, exit doors could be improperly locked during the daily operation for security \begin{table}

Another example is the storage of highly hazard contents that may be present during the normal daily operation of a facility. To focus on the inspection of items in commercial and public buildings that have dynamic features, this study proposes a social approach that combines collective knowledge from the general public with building information modeling (BIM)-based virtual reality (VR) technology to identify possible issues related to fire safety. Based on this approach, a prototype mobile app called iInspect was developed. With the help of an indoor real-time location system (RTLS), iInspect notifies occupants when they are near an item in the building that is fire safety--related and could be inspected (for example, a fire door). If a person has some spare time and would like to perform an inspection, the app will display the VR scene on the user's mobile phone to help him/her locate the items to be inspected and will provide a checklist and some additional information such as images of the correct status of the item and common problems or issues with the item. App users can perform an inspection and upload a report along with the necessary photos for verification purposes. The office of the appropriate authority will be notified and can take the necessary action(s) according to the severity of the issue. In the following section of the paper, we will review related concepts including crowdsourcing and collective intelligence, BIM and VR, and RTLS. The system design for iInspect will be presented in terms of framework design, inspection content, and incentive mechanisms for social participation. A case study is conducted to examine and verify the usability of this approach, and the limitations of the system and possible uses of this approach in other inspection-related areas will be discussed.
