Engineering construction needs visual progress management tools to integrate BIM and VR to develop a visualized and multi-terminal construction progress demonstration system with rich information. Building the standard construction model with Revit, this article modifies the texture of materials using 3DMAX and then imports the model to Unity3D SO as to develop a cross-platform construction progress system. Model information in Revit is transmitted to Unity3D in IFC format, which can be easily released to the PC. Web and mobile terminal and provide better service for construction management.
