With the vigorous promotion of BIM technology in China, the application of BIM technology in housing construction projects in becoming increasingly implementable in areas such as deepening design of drawings, 5D collaborative construction management, construction technology optimization, visual construction disclosure, collision inspection and etc., achieving remarkable effects. However, considering the specific characteristics of the municipal engineering, there are many problems faced in the creation of the model, the transfer of the models between platforms and the applicability of the application platform, making an unoptimistic situation for current BIM application in municipal engineering projects. Taking a typical municipal public works of the bid section GZQ-DQJGW-002 of road and bridge and pipeline network project in Beijing new airport workshop project (municipal transportation) as an example, this paper explores the practical application of BIM technology in the construction process, sorting out some innovative applications of BIM technology with popularization and application value in the same field. At the same time, the application of unconventional BIM software is summarized, which plays a guiding role in the implementation of municipal engineering BIM technology.
