Abstract
As the need for digital transformation (DT) increased in order to improve productivity in the construction industry, the market for building information modeling (BIM), the main technology of DT, gradually expanded. Strategies for promoting BIM have been established and announced in South Korea. Accordingly, the related regulations have been modified and there is continuous investment in BIM. Despite these efforts, BIM adoption has not gone smoothly. This study aims to empirically verify an acceptance model as of 2021 based on the BIM acceptance models proposed by previous studies, and to propose implications by analyzing the significant relationship changes in acceptance models by period. It found a change in the mechanism of accepting BIM over time and derived implications about the causes of changes in connection with the comparative analysis results and the status of BIM-related policy announcements. If promotion strategies are inspected and adoption strategies suitable for each period are established through the regular verification of the BIM acceptance mechanism, we expect that the effectiveness and efficiency of investments in promoting BIM will improve.
