BG&E Resources has completed the detailed design, including shop detailing, construction support and commissioning support, of the solution we developed during the feasibility study at Marandoo PC to resolve structural dynamics. The design optimisation significantly reduced electrical scope when compared to the feasibility study.

Our team also provided access to the model in a virtual reality environment giving both Rio Tinto and construction contractor the ability to prepare for shutdown work in a fully immersive environment. This resulted in the contractor being able to better plan its their work and minimise the risk of issues during construction and commissioning.

Vibration at Hope Downs 4 has been identified as a class IV risk. BGER’s solution incorporated offering up a large concrete and steel isolation frame to the underside of the existing floor and mounting it on air springs. This innovative solution simplified the complex dynamic problem to a solution that was easy to understand.

The study was completed under budget and on schedule.
