BIM model was created with full professional construction drawing depth, and 3D roaming animation and interactive operation model of the whole section were made, to assist in design review. Making VR interactive models such as Muzaling tunnel, Miaozi hub and Nianpangou grand bridge, to realize digital results delivery. Using BIM model to review 2D construction drawings, improve the quality of design drawings, and accumulate rich experience in rapid modeling technology. Relying on this project, we have applied for and completed one scientific research project, won 5 BIM awards, applied for 4 invention patents, and obtained 9 software copyrights.
