Building Information Modeling, as a digital representation, is estimated to decrease average project costs by approximately 10% and accelerate average project schedules by around 7%. Acknowledging the benefits of Building Information Modeling (BIM), the Indonesian government has implemented several regulations to promote its adoption. These include Ministerial Regulation No. 22/PRT/M/2018 of the Ministry of Public Works and Public Housing, the BIM Protocol Standard of the Ministry of Public Works and Housing for 2020, the Circular Letter No. 11/SE/Db/2021 of the Director General of Highways, and Government Regulation No. 16 of 2021. Despite these regulatory efforts, the extent to which BIM has been embraced also its impact on project cost and time remain unclear. Although the regulations aim to promote the adoption of Building Information Modeling (BIM), it remains uncertain whether BIM has been widely implemented and if its application has impacted project cost and time performance. The absence of comprehensive and measurable information creates difficulties in evaluating the significance of BIM adoption and its real impact on project performance. This study employed qualitative methods, such as a review of related literature, as well as quantitative methods, including questionnaires and interviews with 4 BIM users involved in 40 construction projects that served as the research sample. The findings indicate that construction projects implementing BIM from 2018 to 2024 have demonstrated regulatory compliance with guidelines about the duty to apply BIM in Indonesia. However, while the usage of BIM in projects has been dominated up to BIM 5D, its implementation remains suboptimal, as the majority of new projects have only reached BIM level 1. Meanwhile, the application of BIM to project cost and time performance remains in its early stages, with a focus on extracting cost data and scheduling studies. Furthermore, correlation analyses conducted using IBM SPSS version 26.0 software indicate that BIM implementation has a significant relationship with time performance, but not with cost performance. This suggests that going forward, BIM implementation should prioritize improving time performance over other performance metrics.
