This paper mainly analyzes the data from the specific application of BIM Technology and virtual reality technology in construction engineering, and fully excavates the specific application of construction technology and model simulation in construction engineering. In the construction project, the key part is the construction information model and construction information management. Therefore, the three-dimensional model of the project is created by using virtual reality technology, and the real construction scene is simulated by using virtual simulation technology. BIM Technology can quickly carry out graphic visualization, architectural drawing, information data simulation and so on. Through the integration and innovation of BIM Technology and virtual reality technology, the building information model is established to provide a stable system platform for the development of construction engineering. Therefore, the application of BIM Technology and virtual reality technology in construction engineering is of great significance to the design and optimization of construction engineering.
