The Trans Sumatera Toll Road is a 2,770-kilometer tollway being developed by state-owned EPC contractor PT. Hutama Karya (HK) for the Indonesian Government. Extending from Aceh to Lampung, this ambitious US $21.4 billion project will accelerate economic development in Sumatera (known as Sumatra in English), the sixth largest island in the world. HK’s team of contractors includes IT service provider PT. FKA Global, a Bentley Channel Partner uniquely qualified to set up the BIM technology, centralized data repository, and collaboration platform. In addition to significant project delivery time and cost savings, Bentley applications produced the intelligent data HK required for asset life cycle management upon turnover.
Planning project handover
One of 13,466 tropical islands in the Indonesian archipelago, Sumatera is heavily forested with mountainous terrain and smoldering volcanos. The mostly rural population of roughly 50.4 million people stretches across seven provinces and one autonomous province. The government of Indonesia undertook the Trans Sumatera Toll Road project as part of a large-scale road construction program to spur development on the island. The Public Works and Public Housing Ministry appointed owner-operator HK to develop the tollway and launch operations in sections, including 17 main lines and seven connecting lines.
The tollway consists of four main corridors, plus three priority corridors that are part of the Sumatera road network. The four main corridors include sections connecting Lampung and Palembang (358 kilometers), Palembang and Pekanbaru (610 kilometers), Pekanbaru and Medan (548 kilometers), and Medan and Banda Aceh (460 kilometers). 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 infrastructure projects for the government and is known as a pioneer in construction 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 Sumatera 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, including 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 management 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 subcontractors. 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, revision 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 communication among stakeholders. Dynamic 3D modeling enhanced the geometric design process, allowing HK’s team to find the most effective 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 Indonesia’s Economic Development (MP3EI), the Trans Sumatera Toll Road will improve access to remote sectors of the second largest island in Indonesia. 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.

The Year in Infrastructure 2018 Conference will be held Oct. 15-18 in London at the Hilton London Metropole. Presented by Bentley Institute, the conference is a global gathering of industry executives and thought leaders in the design, construction, and operations of the world’s infrastructure. The theme of this year’s conference is Going Digital: Advancements in Infrastructure.
The conference features nearly 70 speakers and more than 50 sessions, including keynotes by leading industry experts, interactive workshops, forums, panel discussions, and product demonstrations. A Technology Pavilion features exhibits and presentations from Bentley Systems and its strategic partners Microsoft, Siemens, Topcon, and Bureau Veritas.
On the first day of the conference, Bentley Institute will host Digital Advancement Academies, featuring presentations and interactive discussions with subject matter experts who provide insights and best practices in their areas of expertise, including reality modeling, BIM strategy, and “constructioneering.”
The conference also includes the selection and announcement of the winners of Bentley’s Year in Infrastructure 2018 Awards (formerly known as the Be Inspired Awards), which honor the extraordinary infrastructure projects by users of Bentley software throughout the world.
During six industry-focused forums — Buildings and Campuses, Digital Cities, Industrial Infrastructure, Rail and Transit, Roads and Bridges, and Utilities and Water — more than 55 awards finalists will present their projects to independent panels of jurors, more than 100 members of the press, and conference attendees. From those presentations, winners are selected by the jurors and will be announced at the conclusion of the conference on October 18 during an evening ceremony and gala.
In October 2019, the Year in Infrastructure Conference will return to the Marina Bay Sands Expo and Convention Centre in Singapore.
