As a national strategy to support the country’s economic growth, Indonesia’s capital city relocation to Borneo Island has been on the national agenda since 2022. This megaproject extremely prioritizes high-quality results and punctuality while located in relatively remote areas. One key challenge in the development process is earthwork, particularly the time-consuming soil compaction testing required for every layer of construction. Thus, it is a common demand for all the construction players to implement innovative technology and methods to enhance and maintain construction productivity, quality, and efficiency. Commencing with this concern, this study discusses the implementation of intelligent compaction system to support soil and granular compaction processes in the construction of Indonesia’s New Capital City Toll Road Segment Balang Island Bridge–Riko Junction by integrating compaction equipment’s drum with a satellite positioning kit and several on-machine sensors to evaluate and monitor compaction processes in real-time. The automation process is made possible by integrating BIM-generated surfaces with field data obtained from GNSS receivers via wireless operating systems’ tools, while the monitoring process can be carried out via a cloud-based collaboration platform. The results of this study suggest that intelligent compaction system provides more accurate compaction measurement through the evaluation of Compaction Meter Value (CMV), leading to improved construction precision. Additionally, the system contributes to lean construction practices by reducing labor, time, and material costs, while significantly enhancing productivity.
