| Abstract |
Both Korea and China have designated BIM application compulsory targets to revitalize BIM in the construction industry and established a
BIM revitalization promotion plan. In order to obtain the expected effect of using BIM, it is necessary not only to purchase tools for BIM
use and to prepare related systems and organizations, but also to identify and reflect user requirements through periodic performance
evaluation from the user's point of view. Therefore, this study examines the strategies established for BIM activation in Korea and China,
evaluates each country's BIM utilization performance, checks the investment direction for each country's BIM activation, and derives key
improvement factors and improvement plans. The importance and performance of the expected effects of BIM are measured on a 7-point
scale for construction industry practitioners in Korea and China who have experience in using BIM. We verify whether there is a significant
difference in the importance and performance using t-test and derive priority improvement priorities for each country using IPA. According to
the results of the analysis, in Korea, the effects of high importance were also high in performance. This is judged to be the result of
relatively long-term investment based on a specific implementation plan for revitalizing BIM. On the other hand, unlike Korea, China does
not show a specific trend, and ‘Maintain relations with the client’ has the highest performance in both the design and construction stages. It
is judged that China is greatly influenced by external factors in the use of BIM. Through this, it is meaningful not only to identify
improvement plans for each country, but also to suggest the necessity of establishing a specific implementation plan while presenting the
characteristics of BIM utilization by adoption time. |
