The International Symposium on Innovative Metro Development (CITURC 2025) was held from 17 to 19 October 2025 at the Wuzhou Guest House, Shenzhen, China. Organized by the CREC International Tunnelling and Underground Space Research Center (CITURC) in collaboration with the China Railway Engineering Equipment Group Co., Ltd., the event gathered engineers, researchers, and industry leaders to discuss the future of metro and underground space development.
Supported by the Institution of Engineers Malaysia (IEM), Hong Kong Institution of Engineers (HKIE), Tunnelling and Underground Construction Society Singapore (TUCSS), and the Japan Tunnelling Association, the symposium reflected strong regional commitment toward sustainable, intelligent, and well-integrated urban rail infrastructure. Participants hailed not only from China but also from Georgia, Bangladesh, Singapore, Indonesia, Thailand, and Malaysia, sharing insights on metro design, construction, and digital innovations.
🚉Symposium Highlights🚉
The program began with technical presentations focusing on operation, maintenance, and underground space development. Key sessions included Sun Xinxian (Shenzhen Metro Group Co., Ltd.) on intelligent maintenance operations, and Ge Tiejun from the same organization on new models of metro overhaul.
Discussions were also led by Zhixin of Guangzhou Metro Group Co., Ltd., focusing on proactive maintenance for urban rail transit, and Ruan Ying from Guangzhou Metro Group, who shared case studies on integrated metro development in the Guangdong–Hong Kong–Macao Greater Bay Area. Presentations from Zhu Jiangang and Yang Yan (China Railway Academy Group Co., Ltd.) highlighted smart engineering maintenance, monitoring innovations, and structural defect treatments.
🗣️Main Symposium Sessions🗣️
The symposium continued with welcoming remarks by Helen Roth, Executive Director of the International Tunnelling and Underground Space Association (ITA), followed by distinguished speakers including:
Prof. Ir. Dr. Jeffrey Chiang Choong Luin, President of IEM
Mr. Albert Lauga, Vice President of HKIE
Mr. Xongyu Chuey, Vice President and Chief Engineer, China Railway Group Limited
Mr. Shaon Chunming, Vice President, China Civil Engineering Society
Keynote topics explored automation and digitalization, AI-driven predictive maintenance, geological risk management, and integrated metro ecosystems. Shenzhen’s own development trajectory stood out as a benchmark — currently operating 18 metro lines spanning 591.5 km, with 17 additional lines under construction.
🚧Technical Site Visits🚧
The final day featured visits to several advanced metro sites:
Shenzhen Metro Line 14: A 50.3 km operational line with 18 underground stations, developed under the city’s Phase IV blueprint. Impressively, 99% of tunnels were constructed using mechanized excavation, employing up to 51 TBM units concurrently.
Shenzhen Metro Line 22: A 34.8 km line under construction using dual-mode EPB/TBM technology, crossing urban corridors and complex geological conditions.
Wuhe Integrated Transport Hub: A state-of-the-art interchange for Lines 5 and 10, featuring AI-based fault prediction, digital twin asset management, and cloud-based control systems for predictive maintenance.
These visits offered valuable exposure to cutting-edge tunnelling methods — including cut-and-cover, pipe jacking, and prefabrication — aimed at enhancing efficiency and minimizing urban disruption.
🇲🇾 Malaysia’s delegation was led by IEM President Ir. Prof. Dr. Jeffrey Chiang Choong Luin, Assoc. Prof. Ir. Dr. Rini Asnida (Deputy Chairman, IEM Tunnelling and Underground Space Technical Division), Afikah Rahim , and Ts. Dr. from Universiti Teknologi Malaysia (UTM).
Their participation showed Malaysia’s growing engagement in tunnel and metro engineering. The team exchanged insights with regional and Chinese partners, exploring potential collaborations in research, technology transfer, and academic mobility, especially in line with UTM’s ongoing initiatives to expand expertise in tunnel engineering and urban infrastructure resilience.
