Despite BIM technology influencing architectural design companies profoundly, there has still been an under-representation of architectural designers’ continuous use intention (CUI) regarding it. This paper aims to empirically examine what factors can potentially affect architectural designers’ CUI of BIM through the integration of a technology acceptance model (TAM) and an expectation confirmation theory (ECT). Sample data for empirical research were collected from architectural design companies in Qingdao, China. A total of 207 valid questionnaires were analyzed by using a structural equation modeling method. The findings show that the proposed theoretical model has good explanatory abilities for architectural designers’ CUI. Perceived ease of use and satisfaction significantly and directly affect CUI, whereas perceived usefulness and conformation have an indirect influence on CUI via satisfaction. This study contributes to a deepened understanding of architectural designers’ CUI regarding BIM. In order to further promote continuous use practices of BIM, valuable insights are provided for designers, companies, and software developers.
