Abstract: Taking the FX-8 bid of Fuzhou Xiamen railway as an example, this paper establishes a BIM model for the whole bid section to implement the deepening scheme design and the simulation analysis of the key construction sites. The CAD, satellite map, aerial photography and tilt photography model technologies are comprehensively applied to realize the boundary determination of red line, investigation of construction interference and preliminary planning in the early stage of construction, as well as to achieve the applications of 3D laser scanning in tunnel excavation quality control, spray maintenance, beam storage path optimization, beam transportation simulation, tooling design, and etc. According to the special situation of the bridge and tunnel, the visual progress management and 4D simulation module are developed, as well as the construction management platform, which realizes integrated management and improves management efficiency. The modules of construction monitoring and demolition management are developed and integrated into the intelligent control center for unified maintenance and management, which contributes to the formation of a solution for BIM application of long-distance belt project.
