AECOM recently completed engineering and construction for the design and construction for Tailings Storage Facility #5 for the Olympic Dam near Roxby Downs, South Australia. The multi-million dollar project was performed under an Engineering, Procurement and Construction contract for BHP Billiton. The project was faced with significant construction challenges in a remote desert mining climate, extreme heat in the summer months and lack of water. Cost savings were achieved through design location and configuration as well as contracting efficiencies.
