en.Wedoany.com Reported - MCC has completed a 33.4 km underground utility tunnel project in the Guangdong-Macao In-Depth Cooperation Zone in Hengqin. At the time of its completion, it was the longest single-section utility tunnel in China with the largest one-time investment scale, and it was the first in the industry to receive both the "Luban Award" and the "Zhan Tianyou Award."
Launched in 2009, the Hengqin project was designed to a once-in-a-century flood protection standard, constructing an underground municipal framework on tidal flat geology. The tunnel integrates all types of pipeline networks, including power, telecommunications, water supply, reclaimed water, heating, cooling, and vacuum waste collection, transforming the traditional scattered direct-burial construction model. In 2015, the Ministry of Housing and Urban-Rural Development designated the project as a national model, organizing on-site inspections by government and enterprise experts from over 70 cities across China. The "Hengqin Experience" became a benchmark for urban underground pipeline network construction nationwide.
MCC has achieved multiple industry firsts in this field: establishing China's first specialized company for utility tunnel investment, construction, and operation; setting up the country's first 100-billion-yuan urban utility tunnel industry fund; founding the first professional comprehensive utility tunnel technology research institute; and being selected for the national "Mayor's Home" utility tunnel expert think tank, building an integrated "investment + construction + R&D + operation and maintenance" industrial system.
In terms of standard development, its subsidiary MCC Jingcheng led the compilation of the national standard "Technical Standard for Operation, Maintenance, and Safety of Urban Underground Utility Tunnels," while China MCC20 Group led the compilation of the national architectural standard design atlas "Cast-in-Place Concrete Utility Tunnel" and "Prefabricated Concrete Utility Tunnel Fabrication and Construction." MCC has cumulatively led the compilation of over 40 national, provincial, and industry standards and specifications, and has received 10 provincial and ministerial-level science and technology progress awards.
In terms of business layout, MCC has reached strategic cooperation agreements with more than 30 cities, including Shenzhen, Nanjing, Hefei, Xi'an, and Kunming. Among these, China MCC17 Group undertook the largest underground smart utility tunnel project in Xi'an; MCC Jingcheng built China's first smart utility tunnel project in the Dianzhong New Area of Yunnan, which was selected as a Ministry of Housing and Urban-Rural Development science and technology demonstration project; and China MCC20 Group implemented a comprehensive municipal project in Shenzhen integrating utility tunnels, sponge city concepts, smart municipal services, and river management. Subsidiaries such as China MCC1 Group, MCC Saidi, and MCC South have also advanced benchmark projects in cities like Zhengzhou, Wuhan, Lanzhou, and Nanchang.
In the Xiong'an New Area, MCC undertook the underground utility tunnel project in the Rongdong area, which was the "first bid" for the new area's municipal infrastructure. The project applied technologies such as 5G transmission, artificial intelligence, intelligent sensing, and smart decision-making, establishing a full-lifecycle BIM digital management and control system to achieve digital management and control across planning, design, construction, and operation and maintenance. The tunnel is adapted to the deployment needs of next-generation communication networks, computing networks, new power grids, and logistics networks, with reserved space for underground logistics channels. The project has hosted over 400 national and local inspection tours, serving as a demonstration window for smart infrastructure.
