This paper proposes a new design method using BIM technology to solve the problems existing in the design of outdoor electrical pipeline in container port.Based on actual engineering projects of container port and combining with main design key points of outdoor electrical pipeline in container port,this paper adopts BIM 3D design method to describe the whole design process by using 3D design software Revit.In additional,it carries out the comparative analysis between design productions of BIM design method and traditional design method,and directly indicates all advantages of BIM design method.On this basis,this paper is intended to introduce a new 3D design method and the corresponding whole technology route for the detailed design of outdoor electrical pipeline in container port to improve the insufficient of traditional design method.
