Project Overview
Qufu Road Station on Shanghai Metro Line 12 is situated beneath Qufu Road at the intersection with Xizang North Road. To the northeast lies the Phase I construction of Xinmei Taikoo City; northwest is Mongolia Community; southwest borders the established Shanghai Vegetable Auction Co., Ltd.; and the southeast side is designated for future development. The station connects with Line 8 at Xizang North Road and Qufu Road Station.
The station measures 288.4 meters in length, with a standard section net width of 20.5 meters and an island platform width of 12.5 meters. It is designed to accommodate a peak passenger flow of 7,062 people per hour, covering a total construction area of 18,776.2 square meters.
Integration of BIM Technology in Rail Transit Construction
The traditional separation between design, construction, and operation phases in rail transit, combined with limitations of two-dimensional design, creates challenges in post-construction operation, maintenance, and management. BIM (Building Information Modeling) technology addresses these issues by offering a digital, visual, and integrated information management platform that covers the entire project lifecycle.
By establishing a three-dimensional model during design, and integrating civil engineering, mechanical, and electrical data during construction, BIM enables comprehensive and efficient operation and maintenance through informatization.
BIM Technology in the Design Phase
During design, BIM technology facilitates collaborative work by leveraging software such as Autodesk Revit. Designers from various disciplines and locations can collaborate online, sharing real-time access to professional views, design progress, and quality data according to their access permissions.
Further, Autodesk Navisworks is employed in later design stages for pipeline clash detection, large equipment installation planning, and maintenance path design. This process optimizes clearance, pipeline layout, and engineering accuracy, reducing errors, losses, and rework during construction. BIM assists in resolving common construction challenges upfront by allowing virtual simulations and detailed construction disclosures.
BIM Technology in the Construction Phase
In construction, BIM models enriched with time attributes enable four-dimensional simulations of critical tasks such as road crossings and pipeline relocations. This enhances understanding of complex construction points and helps optimize scheduling and resource allocation.
On the project management platform, coordination among all stakeholders is streamlined:
- Operational inspections and BIM model standards are developed.
- Equipment suppliers input product details and maintenance parameters, establishing data standards and input interfaces.
- Monitoring units integrate data into a remote 3D visualization platform.
- Supervisors manage inspections via dedicated platforms.
- Construction teams oversee quality tracking (using RFID) and schedule management, develop chip selection standards, and provide 4D progress monitoring.
- Design teams manage design changes through specialized platforms.
This level of collaboration significantly improves construction progress and efficiency.
BIM Technology in Operation and Maintenance
Shanghai Underground Space Design and Research Institute has developed a BIM-based asset and operation maintenance management system tailored for rail transit facilities. This system integrates facility asset management and equipment maintenance into a 3D visualization platform, enhanced by IoT technology and proprietary handheld devices with chips for onsite management.
Key functions include asset management, maintenance scheduling, and emergency plan management. The system’s database-centric approach consolidates facility models, user manuals, operating parameters, and maintenance cycles, eliminating reliance on paper documents. Moreover, it links maintenance work orders, personnel, and spare parts inventory, while emergency orders connect with response teams and material supplies, boosting operational reliability and emergency responsiveness.
BIM Technology Implementation Overview
The BIM information management platform supports the entire lifecycle of rail transit projects, offering a rich database that includes geometric data, professional attributes, status information, and non-component objects like space and movement behaviors. This comprehensive platform greatly enhances information integration across rail transit engineering.
In terms of application depth, the BIM platform influences design, construction, and operation phases, significantly improving project effectiveness and efficiency.
Furthermore, Autodesk Revit serves as the core software integrating commonly used BIM tools, enhancing both the quality and scope of transmitted information. The project team has developed BIM implementation plans, technical standards, data standards, and software interface standards across all project stages. They have also provided secondary software development and technical support for BIM operation and maintenance during design, construction, and operation.
Basic BIM training has been delivered to all participating parties, advancing BIM technology’s role in Shanghai Metro Line 12.
Summary
The Qufu Road Station project on Shanghai Metro Line 12 demonstrates that BIM technology is essential for rail transit projects. Compared to traditional civil or municipal construction, rail transit projects are characterized by multiple nodes, extensive lines, broad coverage, large scale, high investment, and long construction timelines. Complex mechanical and electrical systems, numerous equipment, and elevated construction and operational risks impose stringent demands on construction quality, operational reliability, and social responsibility.
Thus, establishing a comprehensive information system via BIM is critical to improving management efficiency, enhancing operational reliability and emergency response capabilities, and minimizing safety risks.
