With China’s rapid economic development, China’s urban complex or commercial complex projects can be seen in various cities in the country. According to the relevant data as of September 2013, the number of urban complex on building has been four times as that has been completed. It is expected that the number of urban complexes will increase by 50% to 100% over the next three years. Urban complex, to a certain extent, ease the relative shortage of urban development, the plight of space resources, to give the public to provide high-intensity city activities. However, the development of real estate is no longer the focus of much attention, but the commercial real estate projects as urban sprung up, become the real estate sector upstart. The construction quality of the project directly determines the quality, function and effectiveness of the whole project, so the project construction quality control is the key content of this paper. As the project scale, the construction period is long, uneven construction management, construction process uncontrollable factors, the traditional construction quality control program can not meet the requirements. Therefore, the city complex construction quality control is a difficult task and challenge.BIM is a new technology and method, it can control the construction process, construction conditions and model links, to solve the communication problems between the parties. In this paper, the difficulties in quality control of urban complex engineering construction are analyzed by means of literature research and summarizing research methods. Combining the BIM conditions of construction quality control system and its influence on construction quality control, urban complex engineering construction and exploration application, the quality of urban complex engineering Control methods and conclusions for the construction of complex engineering is valuable for quality control the future development of BIM technology .
