Designing a subway system requires not only addressing the functional aspects of the subway itself but also thoroughly studying the significance of subway lines and stations to meet technological demands. However, as subway stations become increasingly complex, traditional CAD methods struggle to fully express design requirements. Designers also face challenges when analyzing the dynamic processes from subway construction to operation.
To overcome these challenges, BIM technology is essential in subway design. It enables designers to comprehensively consider various factors such as functionality, technology, construction, cost, and safety. This approach helps reduce issues during subway construction and enhances the overall construction quality.
Using BIM for Surprise Inspections in Subway Construction Spaces
Subway construction spaces are often limited in size, which introduces numerous constraints. This can lead to equipment interference and spatial conflicts during construction, significantly reducing productivity and increasing the risk of safety incidents.
To maximize space efficiency, it is crucial to allocate adequate room for various construction specialties, ensuring smooth progress. For instance, determining the robotic arm’s rotation radius and properly planning the movement range of construction personnel helps prevent spatial conflicts between workers and equipment caused by improper construction procedures. Such conflicts not only risk property damage but also endanger lives, generate negative public perception of subway construction, and disrupt the overall project timeline.
Therefore, dynamic simulations of the construction site should be conducted throughout the construction process to identify potential issues. Intelligent algorithms can then optimize mechanical operation radii, personnel movement paths, and the spatial requirements of different specialties. By assessing the likelihood of safety hazards at various locations, these optimizations significantly reduce risks, safeguard lives and property, and ensure the project’s safety.
Prior to conducting surprise inspections, it is important to categorize the space occupied by each component and construction phase. This involves analyzing the spatial needs of different trades and studying the physical forms of components. Some projects include special entities that require unique spatial descriptions, emphasizing their distinct spatial characteristics.
For example, machinery movement during construction mainly involves linear advancement and robotic arm rotation. Special models must be used during construction simulations to analyze machinery activities, detect conflicts between machinery and surrounding elements, and assess collision risks.
