With many bridges and long tunnels, the extremely harsh geographical and natural climatic conditions of the highway located in the western Gobi Desert area of China results in high technical difficulties, construction risks, and management requirements, therefore leads to great challenges to the traditional project construction management. Depending on the development dividend of "BIM+" technology in highway engineering, the paper develops an information integration service platform to employ BIM technology through multi-channel and multi-means hence to solve the problems of project construction management, e.g., difficult information sharing, weak resource coordination and incomplete integration of construction and management, and realize the information management of engineering projects. This paper focuses on the main application of BIM technology in the construction management of a highway project as well as its extended application. Through employing BIM technology to realize the informatization management and innovative application of this project, which provides a reference for the subsequent highway construction.
