In order to improve the intelligent level of man-machine interaction and auxiliary decision, this paper takes a bridge as the engineering background, selects box girder, pier, cap, pile foundation and so on to carry out parametric modeling. The secondary development process of Revit was explored. Based on IFC framework, Revit API functions were used to expand the data dimension of Revit. To make the bridge health inspection system redundant data visualization, to present the effect of real-time data model, can more intuitively understand the health of the bridge, the bridge disease status to make real-time diagnosis, early warning, and put forward the disposal countermeasures. Through the analysis of the model and data, the influence of the bridge under different climate conditions can be understood, so as to work out the most suitable bridge management and maintenance plan, increase the work efficiency in the operation and maintenance stage, and reduce the waste of funds.
