This paper aims at accelerating the deep integration of new generation information technology e.g., BIM Technology, with urban development with its core concept "New Urban Infrastructure Construction" as the core concept, and promoting the transformation and upgrading of urban development, as well as effectively promoting the informatization and intelligent construction of urban construction management. Based on the application of BIM Technology, this paper firstly analyzes the current industry status and existing business problems of engineering construction project approval. Advantages and characteristics of BIM Technology are well functioned in the paper. Moreover, the paper studies the feasibility of the application mode based on BIM in each stage of engineering project construction and further analyzes the key problems of BIM Technology in engineering construction approval. From all the efforts above, this paper puts forward that relying on the new generation of information technology such as BIM, can simplify the approval process, promote the integrated application of BIM Technology in the whole life cycle of engineering project construction, and improve the efficiency of review and approval, which prospects the development of BIM Technology in the future engineering construction approval.
