Qinghai-Tibet Railway (Phase I and Phase II)

The Qinghai-Tibet Railway Line is the world"s longest, most elevated, and highly technologically sophisticated plateau railway. This renowned railway project connecting Xining and Lhasa has two phases that commenced commercial operations on July 1984 and July 2006, respectively. We were solely responsible for the construction of 71.1%, or approximately 1,406 km of both phases of the Qinghai-Tibet Railway Line, including, all construction beyond 4,900 m above sea level and the majority of diÇcult railway lines beyond 4,600 m above sea level of Phase II of the railway, as well as the sections of the railway crossing the Tanggula and Kunlun mountains. We successfully overcame three signiÑcant challenges presented by permafrost, low oxygen levels due to high altitudes and the fragile ecology of the Qinghai-Tibet Plateau. The total contract value of Phase II was approximately RMB13.1 billion;
