This study investigates the integration of Building Information Modelling (BIM) for cultural preservation in infrastructure development in Bali, Indonesia. The primary aim is to analyze how BIM can design buildings harmonizing with the environment while preserving traditional architectural elements. The research employs a mixed-method approach involving qualitative interviews and quantitative questionnaires, targeting 30 infrastructure and building projects in Bali, divided equally between those utilizing BIM and those that do not. This study’s comparison between BIM and non-BIM systems was based on several critical indicators: energy efficiency, resource management, construction waste reduction, and cultural preservation scores. The findings indicate that BIM significantly enhances energy efficiency, resource management, and the documentation and preservation of cultural elements. Specifically, projects employing BIM demonstrated a 15% reduction in energy consumption and a 20% reduction in construction waste compared to non-BIM projects. Furthermore, BIM-enabled projects scored higher in cultural preservation, with an average score of 4.2 out of 5, versus 3.5 out of 5 for non-BIM projects, with these differences being statistically significant (p < 0.05). These results underscore BIM’s potential as a critical tool in promoting sustainable development and cultural preservation in Bali.
