Limiting land occupation, reinventing engineering.
The Wuhan-Guangzhou and Zhengzhou-Xuzhou High-Speed Lines, 1,069 km and 362 km in length respectively, are two of the country’s strategic rail transport corridors. They are both part of China’s 40,000 km high speed railways to-date under the State Council-approved Middle-to-Long Term Railway Network Plan (2005). Egis’s assignments on both projects were to supervise all works on the contracted sections. This included civil engineering, structural works, system commissioning and quality assurance, and managing more than 300 people on the two projects combined. Our participation in these projects is an example of our people taking part in what’s unprecedented in terms of the application of new technologies, economic impact and creating international collaboration between indigenous Chinese engineering standards and French and European engineering practice.
Our work on the Wuhan-Guangzhou HSL related to Contract Package Number 3, a 182 km-long section around the city of Chenzhou in Hunan Province. Here, the challenge was to ensure high bridges and tunnels accounted for a high percentage of the total project. The ultimate aim was to reduce land resources consumed by railway construction and ensure the integrity of Chenzhou’s urban development master planning. This city is envisioned to be developed as the only regional economic hub of the 300 km-diametre tri-provincial area of Hunan, Jiangxi and Guangdong.
On the Zhengzhou-Xuzhou HSL we were awarded Contract Package Number 4, a 57 km section worth an estimated EUR 484 million.
This project required a whole new engineering experience upgrade, due to the use of the brand new CRTS-III ballastless track slabs, a 100% Chinese indigenous design with an accuracy error of no more than 0.5 mm.
