Due to the advantages of good integrity, strong applicability and reasonable stress, the cast-in-place continuous beam bridge has become one of the most widely adopted bridge types. Meanwhile, BIM technologies play increasingly important role in the value of infrastructure construction, but there are still many difficulties during the modeling process of cast-in-place continuous beam bridge. To solve those problems during the process of cast-in-place continuous beam bridge design modeling, such as the slow speed and the complex of upper structure, this research collected the data from circuit design line, created the Revit parametric components, prepared a list of the bridge Excel component parameters and provided Dynamo automatic modeling program, which in overall has presented a set of complete solution based on the pattern of "Revit+Dynamo" cast-in-place continuous beam bridge design modeling method. It enables to model the complex upper part of the structural components, as well as enable the rapid modeling process of bottom structural components. It has greatly improved the degree of refinement and has improved the efficiencies of modeling, also it has provided a more reliable basis for data extraction and data analysis of cast-in-place continuous beam bridge construction.
