Abstract: The rapid development of prefabricated buildings has put forward new requirements in the fi eld of architectural design, and building information technology represented by BIM technology has also brought new development to architectural design. This paper takes a prefabricated shear wall structure residential project as an example to study the application of BIM technology in deepening design, fi nd out the key points and key links of the project design process, summarize the advantages and benefi ts of BIM technology in the project application, analyze the problems in the project application and propose corresponding solutions.
