In the development of expressway construction, the traditional quality management mode has many construction quality problems. In order to improve the quality management efficiencies in the construction process and standardize the quality management process, BIM technologies are applied to the construction quality management. The advantages of BIM technologies have been showed from information modeling, accelerating information transmission, systematic material management, optimizing site construction and machinery. In terms of resource allocation, the quality management in the construction process has been improved. Based on the project of Zhongkai Expressway which adopted BIM digital modeling, this paper has built an information management platform that can control the construction quality in real time. This platform can be participated by many parties, speed up the information transmission and standardize the quality management process. At the same time, all the quality information in the construction process can be stored and accessed at any time, which greatly saves human and material resources.
