en.Wedoany.com Reported - China Metallurgical Group Corporation (hereinafter referred to as "MCC") has in recent years deeply engaged in the construction of urban underground utility tunnels, creating two benchmark projects at the national level in the Guangdong-Macao In-Depth Cooperation Zone in Hengqin, Zhuhai, Guangdong Province, and the Xiong'an New Area in Hebei Province. Among them, the Hengqin underground utility tunnel, with a total length of 33.4 kilometers, is the first regional systematic utility tunnel in China, winning the Luban Prize for China Construction Engineering (China Quality Engineering) and the Tiangong Prize for China Civil Engineering; the underground utility tunnel in the Rongdong area of Xiong'an has pioneered the integration of 5G transmission, artificial intelligence (AI), and building information modeling (BIM) technologies, becoming a national demonstration window for new smart infrastructure.
MCC is the world's largest metallurgical construction contractor and metallurgical enterprise operation service provider. Headquartered in Beijing, it is a core enterprise under China Minmetals Corporation, with businesses covering engineering contracting, real estate development, equipment manufacturing, and resource development. In the field of municipal infrastructure, MCC is a pioneer in China's underground utility tunnel industry, possessing the full industrial chain capability of survey, design, construction, supervision, operation, and maintenance. It has also established the first specialized company for utility tunnel investment, construction, and operation in China, the first hundred-billion-yuan-level urban utility tunnel industry fund, and the first professional utility tunnel technology research institute.
The Hengqin underground utility tunnel project was initiated in 2009, designed and constructed with a once-in-a-century flood prevention standard, building a stable underground municipal framework on tidal flat geology. This tunnel intensively accommodates all types of pipeline networks, including power, communication, water supply, reclaimed water, heating, cooling, and vacuum waste collection, fundamentally changing the traditional scattered direct-burial construction model. It effectively saves urban land resources and solves urban problems such as "road zippers" and "aerial spider webs." In 2015, the Ministry of Housing and Urban-Rural Development of China held a national working conference on underground utility tunnel construction in Hengqin, designating the project as a national model and promoting it to over 70 cities. The "Hengqin experience" has become a universal template for urban underground pipeline network construction across the country.
In the Xiong'an New Area, the underground utility tunnel project in the Rongdong area, undertaken by MCC as the "first bid" for municipal infrastructure in the new area, fully applies internationally leading construction techniques and intelligent construction technologies. This project is the first to integrate new-generation information technologies such as 5G transmission, artificial intelligence, intelligent sensing, and smart decision-making into utility tunnel construction and operation, establishing a full lifecycle BIM digital management and control system. This enables digital and intelligent management and control across the entire process of planning, design, construction, and operation. The project has hosted over 400 observation and inspection visits from all levels across the country, becoming a core support for the three-dimensional development pattern of Xiong'an, characterized as "a city above ground, a city underground, and a city in the cloud."
To date, MCC has reached strategic cooperation agreements with over 30 key cities, including Shenzhen, Nanjing, Hefei, Xi'an, and Kunming. It has led the compilation of more than 40 national, provincial, and industry standards and specifications, and has won 10 provincial and ministerial-level science and technology progress awards. The benchmark underground utility tunnel projects it has built in Hengqin and Xiong'an provide replicable and scalable technical pathways and construction models for the networked, intelligent, and green upgrade of China's urban infrastructure.
