First of all, the use of three-dimensional modeling and building information modeling (BIM) technology, the establishment of construction models used to carry out virtual construction and construction process control, cost control, combined with the combination of virtual reality technology, to achieve virtual construction. Through BIM technology, the consistency of the model and the inheritability of the model information are maintained to realize the effective integration of all stages and aspects of the virtual construction process. Secondly, the model combined with optimization technology, immersive program experience, demonstration and optimization. In order to improve the construction efficiency and safety of the construction program.

2, collision checking, reduce rework;

In the virtual three-dimensional environment to facilitate the discovery of collision conflicts in the design, before the construction of a rapid, comprehensive and accurate check out the design drawings of the errors, omissions and collision between the various disciplines and other issues, so as to reduce the rework in the construction.

3, image progress, 4D virtual;

By linking BIM with the construction progress plan and integrating spatial and temporal information in a visual 4D (3D+Time) model, it can intuitively and accurately reflect the construction process of the whole building and the virtual image progress.
