The US $21.4 billion project will trigger development in the seven provinces of Sumatera Island, improving transportation connectivity for the next 50 to 100 years.
kilometers), Palembang and Pekanbaru (610 kilometers), Pekanbaru and Medan (548 kilometers), and Medan and Banda Aceh (460 kilo- meters). The three additional priority corridors connect Palembang and Bengkulu (303 kilometers), Pekanbaru and Padang (242 kilometers), and Medan and Sibolga (175 kilometers). Jakarta-based HK has a history of developing high-priority infrastruc- ture projects for the government and is known as a pioneer in construc- tion technology and methods. To deliver the Trans Sumatera Toll Road, HK was challenged to exercise a collaborative approach with a team of contractors implementing the latest BIM technology. Upon project handover, it was essential for the team to deliver complete and accurate asset life cycle data to inform HK’s operation and maintenance of the tollway. BIM methodology delivers intelligent data As a leading technology service provider throughout Indonesia, PT. FKA Global has designed and implemented complex IT solutions for seamless collaboration on government projects. For the Trans Suma- tera Toll Road project, FKA Global deployed two Bentley applications and associated mobile apps that became the foundation of HK’s BIM- enabled project delivery methodology. OpenRoads applications enabled construction-driven engineering from basic design through construction and asset handover by contractors. Team members used the full breadth of modeling capabilities, includ- ing design modeling, analytical modeling, reality modeling, and hybrid modeling. The 3D technology streamlined traditional engineering workflows to produce high-quality, integrated designs. ProjectWise provided project collaboration and technical data manage- ment from engineering and construction through as-built drawing and commissioning. The platform provided a centralized repository for the project’s BIM data management and supported mobile workflows, and enabled collaboration among the owner, contractors, and subcontrac-
tors. ProjectWise allowed stakeholders with role-based privileges to share information from any location. Supporting life cycle operations and management Bentley technology enabled project team members to share project information across teams, locations, and disciplines with precision and security. Accurate and timely engineering content management facilitated the team’s technical communications, design reviews, revi- sion control, and asset data handover. The ProjectWise collaboration platform will carry over into asset life cycle management, enabling continued centralized control of the intelligent project data. Bentley’s BIM advancements saved project delivery time and costs by enabling the project team to establish faster, more transparent com- munication among stakeholders. Dynamic 3D modeling enhanced the geometric design process, allowing HK’s team to find the most effec- tive geometry for the complex tollway. The 3D model reviews helped to avoid interferences among disciplines, while the easy conversion of models to shop drawings helped reduce resource hours and errors. Using ProjectWise to give regulators restricted access to safety review documents made for seamless compliance management and fewer delays. As part of the Masterplan for Acceleration and Expansion of Indone- sia’s Economic Development (MP3EI), the Trans Sumatera Toll Road will improve access to remote sectors of the second largest island in In- donesia. From its ambitious start in 2015 to its expected completion in 2025, the tollway’s four main corridors and three priority corridors will improve connectivity and development for the next 50 to 100 years.
