### Basic Overview of the Production Base Project  
This research focuses on the production base of server machines and key components belonging to an independent brand in the Nanjing Intelligent Manufacturing Venture Park. The project is situated in the Jiangbei New District of Nanjing, adjacent to the Sisters-in-Law River to the east, Kechuang Avenue (Zhongxin Road) to the south, Kefeng Road to the west, and the Diversion River Road to the north. The project site area spans 94,878.00 m\({}^{2}\), while the total construction area is 202,140.50 m\({}^{2}\). The production base project of our independent brand comprises two service buildings, three factory buildings, and one basement. The language used is neutral and avoids fillers, ornamental language and emotional evaluations. Among them, Service Building No. 1 (for testing) occupies a construction area of 28,892.82 m\({}^{2}\), has a total of 13 floors, and a building height of 57.10 m; meanwhile, the secondary building has a height of 19.20 m. Service Building No. 2 (for integrated services) has a floor area of 24,672.69 m\({}^{2}\), 9 floors, a building height of 41.90 m, and a secondary building height of 16 m. All technical term abbreviations have been defined, and a logical flow of information is ensured. The three buildings numbered 3 to 5 each have a height of 90 m. Building No. 3 has a floor area of 43,400.62 m\({}^{2}\), spans over 5 floors, and has a building height of 36.10 m. Building No. 4 has a floor area of 43,400.62 m\({}^{2}\), covers 5 floors, and has a building height of 36.10 m. Building No. 5 features a floor area of 46,444.75 m\({}^{2}\), spans over 5 floors, and has a building height of 36.10 m. The basement has a floor area of 14,094.66 m\({}^{2}\), 1 floor, and a height of 4.85 m (Figure 2). Analysis of the Elements of Safety Management Scenarios during the Foundation and Basement Construction Phases  
2.1 Construction Schedule for the Foundation and Basement Construction Phases of the Manufacturing Base Project  
Construction on the production base project began in 2021. Initially, only Plant No. 4 was on schedule for construction due to heritage surveys, whereas the other four buildings remained suspended until the start of 2022 when the surveys were completed. Since then,

construction work on site has resumed systematically. The production base project underwent foundation and basement construction, main structure construction, and renovation construction phases in 2022. Each phase occurred primarily between spring and winter of that year. Following the seasonal development sequence, this report categorizes the different stages of the production base construction site starting with foundation and basement construction during spring, followed by main structure construction in summer and autumn, and ending with renovation stage construction in winter. The report constructs a safety management model for the construction site across various time periods. The construction site's outdoor wind environment is simulated in various construction phases. Results from these simulations are then used to determine the relative safe and hazardous zones of the site during different construction stages in conjunction with an analysis of buffer zones for the machinery and construction materials. These determinations aid in the spatial-temporal safety management of the personnel, materials, and machinery on the construction site.
