# Construction and Application of Safety Management Scenarios at Construction Sites
###### Abstract  
With the rapid development of the construction industry, there have been an uncountable number of damages caused by safety accidents at construction sites. Traditional safety management methods are no longer able to meet the needs of production. This paper presents the concept of constructing safety management scenarios for construction engineering sites. Using a production base project as a research case, it analyzes the natural and human factors involved in constructing spatial-temporal scenarios at construction sites. By employing a spatial-temporal overlay method to analyze multiple safety assessment indicators, a spatial-temporal safety management scenario for the production base project is established. Subsequently, BIM and GIS technologies are applied to perform a spatial-temporal simulation of the construction site safety management scenario. This process delineates safety and hazard areas across different construction phases based on time and spatial dimensions, enabling a comprehensive safety assessment of the construction site of the production base project. The study offers a reference and guidance for improving the level of safety management at construction project sites. construction site safety management; scenario construction; space-time simulation; safety assessment +

for secure communication among staff aids in identifying potential sources of danger [5]. [PERSON] and colleagues (2022) identified limitations to the LEC approach in assessing construction site hazards. The study revealed the impact of human factors on the results obtained [6]. In the field of safety assessment for building construction sites, researchers are enhancing the precision and efficiency of identifying hazardous sources owing to the intricate combination of natural geography, human activities, and hazardous sources present at these sites. (1) One way in which this goal is achieved is through the construction of building construction scenarios. These scenarios involve the application of drone aerial photography technology and a deep learning method to identify the construction site scenes and pinpoint the hazardous sources present. Accordingly, managers can adequately carry out safety control measures. [PERSON] and colleagues (2022) developed a deep learning approach utilizing artificial intelligence's visual relationship capabilities to efficiently detect critical construction scenes on highway bridges [7]. [PERSON] and colleagues (2023) constructed an image database for construction site scene recognition and introduced deep learning methods to achieve efficient identification of construction site safety hazards [8]. (2) Another strategy is to create a simulated fire scene at the construction site, utilizing software to accurately reproduce the construction environment. The current fire status can be analyzed in real time using fluid and path analysis software to aid in the rescue efforts during an actual fire emergency at the site. [PERSON] and colleagues (2022) assessed the modelling performance in relation to specific fire phenomena by utilizing B-RISK and simplified models, enabling fire engineers to develop scenarios objectively [9]. [PERSON] and colleagues (2023) employed the B-RISK model to simulate fire occurrence and evaluate the related risks in a ship scenario [10]. Scholars have used the method of fire scenario construction to effectively improve the efficiency of construction site safety management and reduce the incidence of onsite fire accidents. In 2022, 825,000 fires were reported nationwide, with 2053 deaths, 2122 injuries, and CNV 7.16 billion in direct property damage. Compared to 2021, the number of incidents and deaths increased by 7.8% and 1.2%, respectively, and the number of injuries and property damage decreased by 8.8% and 0.9%, respectively.
