In the current era of continuous efforts in transportation construction, the planning and promotion of railway projects have attracted much attention. On October 10, 2025, a new development came from the construction of the Qianjiang Jishou Railway (Hunan section) - the announcement of geological survey supervision and procurement comparison was officially released. This news is like a stone thrown into a calm lake, causing ripples in the field of transportation construction and making people full of expectations for this important railway connecting Guizhou, Chongqing, and Hunan.

The line starts from Qianjiang Station of the existing Chongqing Guizhou Railway, passes through Qianjiang District, Youyang County, Xiushan County of Chongqing City, Huayuan County, Baojing County, Jishou City of Xiangxi Prefecture, Hunan Province, and finally connects to Jishou East Station of the existing Zhangjihuai Railway. The total length of the newly built line is 224.203km, including 71.563km in Hunan Province and 152.640km in Chongqing City. There are a total of 5 stations along the line, with a designed speed of 350km/h. The project investment is about 45.427 billion yuan, but the final approval is subject to relevant information.

The geological survey supervision services during the initial and final survey (including supplementary survey and construction survey) stages of the Guizhou Jilin Railway (Hunan section) project are rich in content and have significant responsibilities, including but not limited to the following aspects: reviewing the engineering geological survey outline; Supervise the progress, quality, safety, and environmental protection of the engineering geological survey process on site, review whether the engineering geological survey work complies with relevant regulations, specifications, and survey contract requirements, and confirm the workload of the engineering geological survey; Cooperate with the investigation and analysis of geological survey issues during the construction process; Review and accept the geological survey reports and other results of the survey units, and provide clear conclusions on whether the geological survey results meet the requirements of specifications, standards, and professional engineering design; Complete geological survey supervision and other related work in accordance with current and effective national and industry standards, regulations, rules, and relevant documents; After the completion of the supervision work, submit the geological survey supervision report.

The service period for geological survey supervision in this bidding is consistent with the geological survey stage of the project engineering. It is tentatively set at 1825 calendar days from the date of contract signing to the completion of all service content. The specific period shall be subject to the actual needs of the project and the actual requirements of Party A. Keywords: high-speed engineering, high-speed construction

The construction of the Qianjiang Jishou Railway is not only a further improvement of the transportation network, but also an important link for regional coordinated development. The release of the procurement announcement for the comparison and selection of geological survey supervision in the Hunan section has laid a solid foundation for the smooth progress of the project. With the orderly implementation of various tasks, this high-speed railway carrying many expectations is expected to be completed and opened to traffic as soon as possible, injecting strong impetus into the economic and social development of the areas along the line and opening a new chapter in regional development.Editor/Cheng Liting
