BIM has not been systematically applied in infrastructure projects because of its characteristics of numerous construction points, long service cycle and high utilization rate of prefabricated components. Taking the Dapingzi-Dongdi A-level Highway Project of Liupanshui as an example, this paper analyzes and expounds the organic combination of BIM technology with GIS digital module to tackle the construction difficulties of infrastructure projects and to ultimately enhance the competitiveness of enterprises. BIM model provides engineering design information and data carrier for subsequent application, while GIS gives geographic location information for the whole project, which makes follow-up vehicle tracking and material supervision have accurate and efficient information basis. At the same time, a large number of digital modules including stress monitoring modules, electronic weighing module, tunnel positioning module, and infrared monitoring module of explosive depot, are set up in the field. to collect real-time construction information, and eventually integrated into BIM management platform, which greatly optimizes and improves the traditional project management procedures.
