On November 15, the second circulating water station for the EPC general contracting project of the auxiliary facilities for YuNeng Fine Chemicals’ 1 million tons per year high-end chemicals and new materials facility at the Northwest Branch was successfully completed, providing strong impetus for the smooth advancement of the project’s annual construction goals. The axis dimensions of the second circulating water station are 124 meters by 20 meters, with a building height of 20.8 meters. A total of 972.3 tons of steel bars were used, 6540.2 cubic meters of concrete was poured, and 37,102.47 square meters of formwork was employed; it is a structure of large scale with high technical requirements. Since the project commenced, the project team has always adhered to the core principle of \"safety first, quality foremost.\" After 140 days of round-the-clock effort, it successfully completed the construction of the main structure to a high standard.
