PT. Hutama Karya is responsible for constructing the Trans Sumatera toll road, spanning 2,800 kilometers across Sumatra Island in Indonesia. The Serbelawan to Pematangsiantar section is a 28-kilometer expressway projected to shorten travel time by 50%. Located in a remote and dense forest, the project presented data acquisition challenges while working with numerous disciplines and software platforms. Having experience using various BIM platforms, they sought interoperable digital modeling technology to accommodate large files and improve project collaboration.They selected ContextCapture to deliver an accurate reality mesh of the remote project area in 28 days, compared to the 120 days it would have taken using conventional survey methods. Using OpenRoads and OpenBridge streamlined data and workflows, shortening coordination and approval time by up to 34 days, while PLAXIS helped avoid potential critical failure due to soft soil conditions. Bentley’s integrated digital solution resolved compatibility issues and clashes, provided data continuity, and optimized collaboration to save USD 2.18 million.
