With the increasing detection requirements of municipal road and bridge, the detection data analysis and application depth are also increasing. How to make the detection data more effectively and vividly reflect the technical conditions of road and bridge has become the basic demand of more and more using units. Aiming at this phenomenon, the basic path of road and bridge detection data combined with BIM technique is introduced. The main contents of road and bridge detect data and the deficiency of applications are analyzed and expounded. How to use BIM information model as the implementation method of detection data carrier is specially studied. Which detection data are more urgent to be imported into BIM model are concluded. By analyzing the different demands of each unit, the implementation scheme is proposed for the application scenarios of using the detection data in BIM model, which provide the new idea for the construction and application of BIM information model.
