The government of Indonesia gave PT Hutama Karya, a construction services, developer, and toll road service provider, a mandate to build the Trans Sumatera Toll Road. The USD 37.5 billion mega expressway project stretches 2,800 kilometers across Sumatra Island from the northern tip of Banda Aceh to the southern tip of Bakauheni. To accelerate project completion, PT Hutama Karya has joined with other infrastructure developers to build and operate several sections. The Serbelawan to Pematangsiantar section spans 28 kilometers and is projected to shorten travel time by 50%. Located in a remote and dense forest, the team faced data acquisition challenges while working with numerous disciplines and software platforms. Having experience using various BIM platforms, PT Hutama Karya 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. By May of 2021, 663 kilometers of the road had been constructed and in operation. The entire project is expected to be completed by 2024.
