PT Hutama Karya (Hutama) is delivering Phase 2A of Jakarta’s MRT, involving construction of two main underground stations. Upon completion, the rail line will enhance citywide connectivity and mobility, integrating with Jakarta’s entire transportation network to reduce traffic congestion and carbon emissions by up to 35%. Located in a dense urban area, the project presented site constraints and complicated ground conditions, demanding meticulous planning and scheduling. To address these issues, Hutama needed a comprehensive, integrated digital solution.  Hutama selected Leapfrog and PLAXIS for geotechnical modeling and analysis, SYNCHRO for 4D planning and construction simulation, and ProjectWise and iTwin to establish a digital twin. Bentley’s geotechnical applications improved soil data collection and analysis by up to 95% and mitigated risks during excavation, saving up to USD 2.5 million. SYNCHRO 4D reduced heavy equipment use, promoting eco-friendly construction to save 50 tons of carbon emissions. Through real-time digital collaboration and data analysis, Hutama streamlined coordination and communication, slashing on-site operational inspection efforts by 90%.
