Key Challenges
- Significant dust from existing tailing dam – RJV provided additional operators to operate client provided water carts
- Communications on site were slow – RJV installed at their own cost a Starlink Service to improve external communication and reporting
- Machine parts availability – RJV improved parts stock holding on site and quickly responded to breakdowns and scheduled maintenance
- Working around the existing decant and return water pipeline RJV had to maintain flexibility in approach to ensure the client’s deposition strategy was adhered to
RJV Advantage
- Flexible to accommodate client needs regarding deposition strategy
- Significant equipment availability, and a peak of up to 70 items of plant and equipment were operating onsite at a time
Innovation
RJV implemented a Navman Fleet Management Systems to track equipment usage and availability. All trim works were completed with GPS enabled equipment to a precise construction tolerance.
