In connection with Ningbo Chenglang Bridge project's characteristics of complicated structure and mode, large horizontal scale, narrow construction yard, short construction period, etc., BIM technology is applied to direct construction of the project. Revit series software is applied to establish parametric model for Chenglang Bridge, and collision inspection, optimization of construction scheme, virtual construction and complicated process disclosure, etc. are finished. Through independent development of construction management platform, control on security, quality, and progress as well as cost are realized in bridge construction management. With satisfactory effect, the project provides reference for BIMapplication to like bridgework. Chenglang Bridge project has complicated structure and mode, large horizontal scale, narrow construction yard, short construction period. In the former experience-dominated construction method, the construction course is uncontrollable, and construction result is indefinite, prone to causing hard-to-estimated losses, so this method cannot meet actual demand any longer. Applying BIM technology to conduct virtual construction for bridge construction course before construction can decrease accidents and improve engineering quality. Meanwhile, this can facilitate construction units' coordinating construction sequence of different specialties, organizing in advance professional squad to enter the site for construction, preparing equipment, site and turnover materials, etc. to actualize informatized, visualized and integrated management over construction yard, course and complicated construction procedure, achieve dynamic control ([1]) over labor service, physical resources and cost in construction course. The owners suggested application of BIM technology to serve the project's construction in early planning period of project, and it is required to constantly explore BIM related techniques in practice to solve difficulties in actual project. The paper adopts BIM technology to construct Chenglang Bridge, realizes overall planning of project, explores construction management experience of application of BIM technology in full life cycle of bridgework, excogitates a set of key BIMtechnologies suiting bridgework, and lays some foundation for BIMapplication to future bridgework.
