1. Project Introduction
The Hong Kong Zhuhai Macao Bridge is a key segment of the G94 Pearl River Delta Ring Expressway, designed for speeds between 100 and 120 km/h. The route begins at the artificial island near Hong Kong International Airport, connects to the artificial island at Zhuhai/Macao Port and the Zhuhai Connection Line to the west, and terminates at Hongwan, Zhuhai. The total length spans 55 kilometers.
This massive bridge links Hong Kong, Zhuhai, and Macao, playing a vital strategic role in advancing the economic development of these regions and the western bank of the Pearl River Delta. Construction of the main project started on December 15, 2009, with the first phase scheduled for completion in 2017. The investment exceeds 100 billion yuan, and the project is expected to take about eight years to complete.
2. Project Contract Details
On April 16, 2015, a contract signing ceremony was held in Zhuhai for the main building project (CA01 contract section) of the Hong Kong Zhuhai Macao Bridge. The project is undertaken by the Zhuhai Branch of Hunan Construction Engineering Group Southern Engineering Bureau. Ye Xinping, Chairman and Party Secretary of Hunan Construction Group, and Zhu Yongling, Director of the Hong Kong Zhuhai Macao Bridge Management Bureau, jointly signed the contract.
The contract value is 468.5 million yuan, covering the main construction of the bridge management area, management and maintenance center, east and west artificial islands of the island tunnel project—including steel structure works—decoration and renovation (including curtain walls), equipment procurement and installation, night lighting, landscaping, and other associated works. The total project area is 107,997 square meters.
3. Owner’s Requirements
The Hong Kong Zhuhai Macao Bridge is a world-class project that demands the highest standards. Construction of the transportation engineering began several years ago, but at that time BIM (Building Information Modeling) technology was not mature in China and was not adopted. Given the complexity of multiple disciplines and intricate piping systems involved, pipeline clashes and other issues may arise during construction.
Currently, BIM applications for pipeline integration in China have become relatively mature, demonstrating clear advantages in quality and safety management as well as cost control. The project owner explicitly requires BIM technology in the contract, specifying a model accuracy of LOD500. The final delivered model must include comprehensive component information to support future operations and maintenance.
4. BIM Team On-Site Service
In response to the owner’s requirements, project leaders established a BIM technology leadership team to develop a BIM service plan. On May 12, 2015, Shi Tuo, head of the Hunan Construction Engineering BIM Center, led a seven-member BIM team to conduct an on-site inspection of the Hong Kong Zhuhai Macao Bridge. They held two in-depth discussions with Liu Jin, Minister of the Transport Engineering Department of the Bridge Management Bureau.
At the meeting, Minister Liu Jin emphasized the need to complete nearly 20 specialized control rooms for systems such as strong and weak electricity, water, and monitoring within the station building. The mechanical and electrical installations are complex, requiring unified coordination through BIM technology. The project also involves numerous specialties, including curtain walls and steel structures, featuring complex shapes and high construction difficulty.
Upon completion, the BIM model will be integrated with the traffic engineering model and managed using third-party software. This model will provide crucial data support for the bridge’s operation and maintenance over the next 120 years.
Shi Tuo shared insights about the current status and future trends of BIM technology in China, the organizational structure and application level of the Hunan Construction Engineering BIM Center, and showcased BIM achievements from projects like Zhangjiajie Hehua Airport, Changsha Jiacheng Hotel, and Chenzhou Yuhou Street. He highlighted that BIM technology significantly reduces costs and shortens construction schedules.
The discussions concluded positively, with both sides agreeing to personnel exchanges in the future. The Hong Kong Zhuhai Macao Bridge is a century-defining project, involving top-tier central enterprises in terms of technology. Hunan Construction is the only provincial state-owned enterprise participating and aims to highlight BIM technology as a key application, maximizing collaborative construction value and delivering a high-quality project.
For this project, the BIM Center is providing full support, planning two years of technical services. Two engineers have already been assigned for three months of on-site service. Their tasks include completing the site model, conducting detailed pre-construction design, and ultimately building a comprehensive professional model to support construction aspects such as materials lists, steel bar cutting, masonry layout, and 3D visualization of complex nodes.
5. BIM Implementation Schedule
• Layout model development: May 17 – May 23
• Comprehensive professional model establishment: May 23 – July 23
• Model optimization: July 23 – August 6
• Completion of LOD300 model: August 17
BIM construction applications will follow the actual project progress.
Summary: BIM is a digital methodology used throughout design, construction, and management phases. It supports an integrated management environment that significantly boosts efficiency and reduces risks across the entire project lifecycle. Moreover, BIM provides valuable data support during operation and maintenance for owners in areas such as spatial management, facility management, concealed engineering, and emergency response.
