The Integrated Transportation Hub Project of Beijing Municipal Administrative Center Station, supervised by MCC CERI, is Asia's largest TOD project and an important hub of the "Beijing-Tianjin-Hebei Rail Transit" network. The project has 8 platforms and 14 tracks, with an average pit depth of 32 m and a maximum depth of 43 m. The reverse construction method was used to overcome the challenges of ultra-large and ultra-deep underground engineering. Once completed, the project will enable direct access to Beijing Capital International Airport in 15 minutes and Xiong'an New Area in 1 hour, becoming a benchmark project for comprehensive transportation that emphasizes low-carbon and green development while also providing economic and social benefits.
