The AU$2 billion Wiggins Island Coal Terminal will provide additional export
capacity for the central Queensland coal industry. This project entailed new rail
works, a rail dump station, a six-kilometer overland conveyor, a stockyard, and
an export berth. The project goals encompassed the adoption of state-of-the-art technical solutions and causing zero harm to the sensitive Great Barrier Reef
marine park and local Gladstone community.
Initiated in a 2D environment, project communication and coordination were
not aligned with best practices so Aurecon Hatch implemented a data-centric
3D environment. Bentley Navigator provided a platform for visualizing complex
designs, which aided reviews across disciplines and by stakeholders. Bentley
3D software helped to reduce the schedule by 15 percent and rework by 10
percent through improved clash detection.
Yarwun Stage 2 is a $1.9 billion expansion of the alumina refinery in Queensland,
Australia, which will increase production by 2 million tons per year for a total
of 3.4 million tons per year. For the Stage 1 design, the main 3D modeling tool
was PDS. In Stage 2, parts of the design referenced Stage 1 models and data.
Therefore, it was a requirement to use PDS for the Stage 2 design.
The client, Rio Tinto, required a data handover and used MicroStation and
Project Wise. Bechtel decided that it was logical to convert the PDS model
into an intelligent 3D model in MicroStation, saving a system upgrade. The
PDS models were converted to MicroStation using Project Wise PDx Dynamic
Review Service. Project Wise was also used to keep the models and data
current and available.
