With the continuous promotion and application of BIM Technology in China, different depth of BIM application is adopted in large municipal bridge engineering. This paper mainly introduces the application of BIM Technology in site, civil engineering, steel structure, and new technology combination of Shenyang East Tower Hunhe bridge project. Through the application of BIM Technology, the difficulties of small site space, difficult component processing and high hoisting risk are well solved; innovative BIM Technology is deeply combined with UAV, virtual reality, augmented reality and other new technologies, and remarkable results are achieved.
