Abstract: In recent years, with the improvement of the informatization level of the construction industry, the application of BIM has gradually matured. Through scientific adjustment of the BIM parameterized model and the use of collision tests and other functions, the feasibility of the design scheme is fully verified, and the construction scheme can be fully optimized for the three-dimensional model, and the construction can be carried out according to the visualization function of the model. The introduction of BIM has greatly helped managers to solve various problems in architectural design and construction, and improved the efficiency of on-site construction. At the same time, because engineering design is an important part of the construction process, it directly affects the benefits of engineering construction. With the advancement of science and technology, construction engineering technology and management methods are also improving. As an advanced technical tool, BIM's application plays an important role in the design, construction and operation of engineering projects. Based on this, this article explains the advantages of BIM in architectural design and construction, and analyzes its specific application in project implementation.
