Abstract: Taking the BIM competition entries of Shaanxi Province in 2020 as an example, this paper expounds the main advantages of BIM inthe project of comprehensive energystation.First, according to the characteristics and workload of the project, the REBRO was determined as the main software, at the same time, choosing the best one among different schemes. Secondly, making the design effort and getting the output, it turned out that using BIM software can improve the quality of the design. To be specific, the direction of pipeline in the station was reasonable and smooth, the spatial utilization was higher, the cost was significantly reduced compared with the original scheme. It impacted the process of construction significantly. Finally, discussing development and application of BIM technology in the future, it should be highly integrated with design and construction.
