Abstract: With the continuous innovation of my country's construction technology system in recent years, modern technology has become the main tool to promote the efficient development of construction engineering. Therefore, the article is based on BIM technology, with light steel structure prefabricated buildings as the main Analyze the object to start research. Comprehensive design, production and construction practical application requirements to analyze the technical system, and through specific engineering cases to illustrate the practical application angle and application content of BIM technology, in order to further enhance the application value of BIM technology in the field of construction, at the same time Lay a good foundation for the high-quality development of prefabricated buildings in my country.
