Project

When PT. Wijaya Karya (WIKA) assumed design duties for the Design and Build Project Harbour Road 2 in North Jakarta, Indonesia, budgeted at USD 530 million, the project team quickly realized that 2D design methods would not deliver the large and complex 8.95-kilometer toll road development on time and under budget. Due to limited space, heavy traffic, underground pipelines, and numerous intersection points, the development will include a 3.95-kilometer double-decker bridge along the Ancol River, which would become the longest double-decker bridge in the world. Additionally, the Indonesian government wanted to avoid placing piers in the river wherever possible to lessen the impact on the environment and ship traffic, and the project had to be completed by the start of the FIFA 2021 U-20 World Cup to facilitate access to the nearby stadium.

Solution

To design such a complex road system in a short amount of time, WIKA transitioned from its traditional 2D design methods and adopted 3D BIM methodology. The organization used unmanned aerial vehicles to photograph 166 hectares of land and produce a reality mesh. WIKA established a connected data environment that allowed designers to determine what features were necessary and to iterate component positioning. Through soil analysis, WIKA reduced the risk of piers settling along the riverbanks. The design work included a 4D model of the construction process, including the movement of heavy equipment in a tight area.
