Abstract：Through the vertical and horizontal comparison of engineering technology means, the past, the present life and the future of BIM are clarified. Three propositions of what BIM technology is (the product of intelligent construction in civil engineering), where it comes from (from mechanical industry technology), and where it is going (replaced by artificial intelligence) are answered. The BIM design technology is compared with other CAD technologies, and the transition path of current design is concluded: the conventional bridge design should use the efficient and quick "BIM modeling+two-dimensional engineering drawing" one-click delivery software, rather than the inefficient general BIM design software; For special bridge structure, designers should master finite element analysis and 3D design software to improve the design quality. The traditional two-dimensional engineering drawing software with the addition of three-dimensional module is the fastest development path of BIM forward design software for conventional Bridges at present; It is not advisable to redevelop the general BIM design software abroad. Using the software combination of "BridgeDesigner +Mars+ BIMFILM", the common operations of BIM forward design, virtual reality and construction simulation of conventional Bridges are demonstrated through examples.
