The virtual construction demonstration project of aluminum alloy formwork and prefabricated components is a combined application of BIM + VR technology in construction engineering jointly developed by China Construction Fourth Engineering Bureau Co., Ltd. and our company. In this project, the construction site scenario is virtualized according to the actual situation. Engineers from China Construction Fourth Engineering Bureau use professional BIM technology to build models of aluminum alloy formwork and prefabricated components and formulate standard construction process flows. Our company's professional VR development engineers conduct engine art production and interactive programming development based on these models and the construction process to reproduce the on - site construction process. In August 2018, this project was exhibited at the China (Shenzhen) International Green Building Industry Exhibition. As a highlight of the exhibition, it attracted great attention from exhibitors. China Construction Fourth Engineering Bureau and our company signed a strategic cooperation agreement to conduct in-depth discussions on the combined application of BIM + VR/AR.
