With the recent continuous improvement of China′s economic level, the national investment on infrastructure constructionhas been increased significantly. In the bridge construction area, the service life of the bridge is constantly growing, andcorrespondingly, the problems on bridge structure disease are increasingly prominent, which claims for higher request on following facility maintenancework. This paper firstly analyses the deficiencies and limitations of present bridge-detection method, then puts forward a BIM UAVbridge detection implementation scheme, and further discusses the combination of BIM technology and UAV and its application in bridge detection. This paper will provide the reference for the future upgrade of bridge detection technology.
