First of all, BIM technology has changed the traditional working mode, which can concentrate all the information in one model and provide an information platform for the staff involved in the decoration, which can eliminate the information asymmetry of various departments and greatly improve the work efficiency. At the same time, the information contained in the model is very comprehensive, which can clearly express the intentions of the owners and designers, so the work can basically be passed at one time, and there will be no large-scale rework, so as to maximize the project benefits.

Secondly, the application of BIM technology can make the modification and printing of construction drawings synchronous, reduce the dependence on labor, improve work efficiency and ensure the construction process.

Finally, the application of BIM technology can make the whole process of the project realize three-dimensional visualization and provide a strong basis for the decision-making and implementation of the project. Even if there are mistakes, they can be found in time, without the process of making a model room first and then carrying out large-scale construction, which not only saves time and cost, but also saves a lot of manpower, material resources and financial resources.

In addition, because BIM is a full information model, it can accurately represent the dimensions and relationships of various components, effectively reduce the accumulated errors in the processing process, and improve the accuracy and aesthetics of decoration.
