BIM technology and operation & maintenance (O&M) are not often considered together. However, current research and applications show that BIM can significantly enhance the O&M phase of engineering projects. Compared to traditional methods, BIM better addresses the needs of O&M personnel. In the context of subway engineering, the following are key BIM application requirements during the operation and maintenance stage:
When the railway company receives the final digital deliverables, it can submit detailed geometric and physical data—especially regarding electromechanical systems—to the operation management system. This data enables monitoring of the actual operational status of systems. Additionally, the collected information supports knowledge management and continuous improvement, ultimately optimizing operational management.
Digital management reduces the need for on-site staff, as automated control and remote monitoring can significantly lower labor costs. During operation, BIM data can be further developed and utilized to monitor and schedule real-time subway operations, facilitating visual and intelligent management.
Regarding maintenance, the BIM information system allows precise localization of buildings and equipment. By integrating QR code data, it can automatically generate reports covering aspects such as equipment service life, replacement cycles, maintenance records, and structural damage levels. This helps accurately determine locations and predict the safety and durability of components including subway stations, sections, and equipment.
Collected data from various sources is integrated into an intuitive virtual model, reducing communication barriers between departments. A well-organized asset management system greatly improves the operation and maintenance quality of subway projects. Traditionally, information from design, construction, and operation phases remains isolated, requiring significant labor to input asset data at the start of operations. Manual data entry also risks errors.
With BIM technology applied during design, extensive engineering information is stored within the information model, allowing quick import into asset management systems. This drastically cuts down data preparation time and reduces labor costs during system initialization. For equipment management, combining BIM with RFID asset tags clarifies equipment location and usage within buildings, streamlining periodic inspections and replacements. This approach supports more informed decisions in subway operation and maintenance.
