Application of BIM Technology in Rail Transit Engineering Design
The system displays various engineering design information through 3D visualization, integrating project data to enhance design efficiency. BIM technology supports planning and design teams in finalizing design concepts and feasibility reviews, while also helping construction teams simulate and precisely control construction procedures before work begins.
Architectural Design: In the early building design stages, BIM combines core electromechanical, water, electrical, and environmental control requirements to optimize spatial layout. Using BIM workflows, it materializes building concepts and forms, allowing for comprehensive environmental analyses in a 3D visual format. This provides valuable references and reviews for owners and designers. BIM models can include building partitions, finishes, materials, doors, and windows. Detailed design drawings and quantity takeoffs can be generated from these models, reducing reliance on 2D drafting and aiding budget planning.
Structural Design: Structural BIM models are developed based on architectural drawings and building models, detailing structural member sizes, foundations, bolt connections, and steel reinforcement layouts. BIM then assists in creating 2D drawings and calculating material quantities.
Water, Electrical, and Environmental Control Design: Designs for water supply, electrical systems, air conditioning, escalators, and other components are created within the BIM 3D environment. The resulting BIM models help produce design drawings and quantity calculation tables, serving as references for budgeting.
Core Electromechanical Design: This includes subsystems such as pipelines, power supply, distribution networks, and communications, all planned and designed using BIM technology within a 3D environment.
The advantage of BIM-assisted design lies in its combination of 3D visualization and integrated collaboration. Through the BIM system, engineers can perform real-time synchronized design reviews. Additionally, clash detection is enabled by comparing information across building partitions, structural elements, water and electrical systems, and core electromechanical facilities. This helps verify design accuracy and completeness while supporting the production of CSD/SEM drawings.
Moreover, the BIM model can be used during the design phase to integrate various tasks from design through construction, enabling analysis and simulation on the constructed model. For example, it can simulate station steel beam lifting procedures, coordinate steel structure assembly with lifting schedules, or assess spatial requirements for precast beam lifting in narrow road sections. This also facilitates evaluating traffic maintenance plans, allowing potential construction challenges to be identified early and corresponding solutions to be developed.
Overall, BIM information management assists engineering teams in vertically consolidating design data, reducing information loss during transmission, and horizontally integrating multidisciplinary construction, commissioning, and operational information. Through 3D visual discussions, potential issues can be detected and resolved early, achieving high-quality design and construction. This significantly supports effective control over the entire project’s schedule, cost, quality, and execution.
