Recently, the group company launched its first BIM application project, led by the Wuhan Railway Fourth Institute Project Department of China Railway Construction. The headquarters design building of the China Railway Fourth Institute held a topping-out ceremony. Utilizing BIM technology, this project has improved construction efficiency by 10% and earned unanimous praise from both supervision and construction teams.
This project features four major characteristics. First, it is situated in the Tiesiyuan residential area, surrounded by numerous homes, resulting in a narrow construction site with strict noise reduction and environmental protection requirements during the building process. Second, the building is located in the Yangtze River’s underground water zone, where the groundwater level is high and water volume substantial. To address this, 28 pumping wells operate continuously, providing 24-hour drainage during foundation pit excavation.
Third, the main building stands approximately 83 meters tall, covering nearly 100,000 square meters. It is classified as a high-rise, large-scale structure and serves as the corporate image project for the China Railway Fourth Academy. Fourth, the project incorporates advanced engineering technologies, including high formwork construction—a first in the domestic construction industry—as well as ten new technologies and seven key techniques. This project is the first among China Railway Construction Group’s ten BIM technology application projects to utilize such innovations. Remarkably, the timeline from groundbreaking to topping out was just one year.
Currently, BIM modeling and optimization for the project have been completed, fully guiding on-site construction. The technology has resolved numerous issues, such as secondary beams being lower than main beams, overly concentrated pipeline installations, pipeline collisions, and insufficient ceiling height. These solutions have yielded excellent results and earned unanimous praise from both the supervision and construction units.
Additionally, part of the project falls under the category of intelligent buildings, with a strong focus on energy conservation and environmental protection throughout the construction process. The project has been officially approved as a Green Construction Demonstration Project.
