Abstract: The application scope of BIM technologies are constantly expanding, which provides great convenience for the construction simulation in the design stage and the early stage of construction, however, the application depth in the later construction stage is insufficient. Lean construction mainly focuses on the application during the construction process to reduce waste and improve efficiencies through lean management. Combining those two can exert their respective advantages better. Based on this, this paper mainly conducts research on BIM application problems in the construction phase, constructs a data-driven project management platform based on BIM and lean construction, solves the problem of extensive management in the construction phase, realizes data-driven lean construction management in the construction process, facilitates the digital transformation of construction enterprises, and provides new methods and ideas for the development and application of BIM technologies.
