Abstract: The Taolaizhao super-grand bridge is located at the Changchun-Lalin River Section of the Beijing-Harbin Expressway. The reconstruction and extension project of this bridge faces many difficulties including complex surrounding natural conditions, rough fieldwork survey in cross-river environments, difficult presentation on the traffic organization, and many other challenges in construction. To better promote the construction schedule and the construction quality, this paper investigates the development of many phases includingsurvey, planning, design, construction, operation and maintenance by integrating several BIM software, which has established a consolidate foundationfor the future 3D integrated and coordinated application of the BIM technology, as well as the index optimization, in the reconstruction and extension project.
