Spanning 2,844 kilometers, the Trans Sumatra toll road is crucial for regional development, reducing travel times, facilitating trade and tourism, and enhancing connectivity. PT Hutama Karya plays a major role in strategic planning, design, and construction management, specifically regarding geotechnical data management. The complex terrain, diverse soil conditions, and project scale presented challenges with managing and integrating the voluminous geotechnical data. Hutama realized that they needed an advanced technology solution to streamline data workflows, enable 3D modeling, and support collaborative design processes.  

Leveraging Bentley’s Open applications with Leapfrog and PLAXIS, Hutama established a collaborative, model-based design environment and single source of truth for comprehensive management of geotechnical data, integrating subsurface models for robust geotechnical assessments to ensure roadway safety. Along the 40-kilometer toll road section from Regat to Pekanbaru, Hutama optimized soil stabilization to avoid potential losses that saved USD 185 million. Working in a connected digital ecosystem increased productivity by 15%, saving 6,000 work hours. The digital geotechnical database provides an invaluable asset for ongoing infrastructure management and future regional development.
