Abstract: With the continuous promotion and application of BIM technologies in the transportation infrastructure industries, digitalized information design has played a more important role. Through the application experience of BIM technology in the design stage of the Dezhou-Shangrao Expressway (G3W), this paper analyzed multi-layer application of BIM technologies during the development of highway engineering design. These implementations are including BIM+GIS design, highway engineering based multi-disciplines design check, component coding system and extension to help improving design qualities and efficiencies. This paper has concluded the application of BIM technologies during the entire process of design phase, which has provided an effective data foundation and reference basis for the life cycle BIM implementations in highway engineering.
