As being traditional industries in China, construction companies are playing important role to contribute the national economy, but it has limitation in long period and large resource consumption. The application of UAV in the construction industry can not only improve the project construction quality and increase the construction progress, but can also have great value to improve the efficiency of project management and truly realize the control of the project with the integration of BIM technology. Combined with the application of building construction engineering, this paper analyzes the selection of UAV, measuring tool, flight control software and BIM data processing software, which explores the standardization of BIM + UAV application path. Meanwhile, the combination of UAV aerial survey technology and BIM technology is used to fit the solid model and virtual model, which record the whole process of construction to solve the problems in earthwork calculation and progress simulation.
