# Construction and Application of Safety Management Scenarios at Construction Sites
###### Abstract
Additionally, the number of fire accidents at construction sites and in high-rise buildings has risen significantly (data from [[https://www.119.gov.cn/](https://www.119.gov.cn/)]([https://www.119.gov.cn/](https://www.119.gov.cn/)) (accessed on 26 December 2023)). In the construction site fire visualization study, BIM and GIS technologies are used to simulate the fire scene onsite and locate the fire-prone areas to help managers carry out control. [PERSON] et al. (2013) designed and implemented an electrical fire early warning system based on the CORTEX-M3 platform, which is designed to prevent electrical fires by determining the residual current and the ambient temperature, as well as having a friendly human-computer interaction interface [11]. [PERSON] et al. (2014) constructed an environmentally aware RF beacon deployment (EASBL) algorithm based on sequential localization, which is able to locate first responders and people trapped in buildings during firefighting emergency operations [12]. A safety evaluation of a construction site necessitates identifying the levels of safety impact associated with hazardous sources. This target can be achieved by developing a construction site safety evaluation index system that considers key parameters relating to personnel, environment, goods, technology, management, and other relevant factors. By using this system to evaluate safety, accurately determining the safety status of the construction site becomes possible. [PERSON] and colleagues (2022) developed a safety evaluation system for subterranean construction, focusing on people, events, and objects. The C-OWA algorithm was employed to assess the significance of safety evaluation criteria [13]. [PERSON] and colleagues (2023) determined that assessing worker safety within their work environment achieves precision when the Personal Protective Equipment (PPE) system is used [14]. The use of BIM technology in a construction site safety management initiative is equivalent to the second revolution in the construction industry; it is widely used in bridge engineering, municipal engineering, mechanical and electrical engineering, tunneling, room engineering, railroad engineering and other construction projects [15]. Traditionalconstruction safety management mostly adopts 2D and 3D management tools, mostly using 3D models to reproduce the site situation and identify the sources of danger by comparing the model with the construction nodes on site in order to achieve safety control. However, as China's urbanization process continues to accelerate, urban land resources are greatly reduced; in order to effectively use the land space, high-rise buildings as well as ultra-high-rise buildings came into being [16]. The traditional 2D and3D construction management tools can no longer meet the needs of production, and the application of BIM will soon go beyond 3D into nD [17]. \"D\" comes from \"dimension\". Four-dimensional BIM adds a time dimension to the 3D building information model, associating the project schedule with the model, which enables the simulation and visualization of the project's progress [18]. Five-dimensional BIM involves the addition of cost dimensions to the building information model, linking the project's material and resource information to the model, allowing for real-time monitoring of changes in project costs and cost analysis and optimization [19]. Scholars have conducted much research on construction site safety management using BIM technology involving six aspects: personnel safety training [20], construction visualization management [21], safety monitoring [22], virtual construction [23], spatial conflict management [24], and site planning and layout [25]. The introduction of 4D and 5D technologies can effectively improve the efficiency of construction site management [26].
