DRA Global has worked with a broad range of clients across the resources sector but more specifically in the Mining and Minerals space. The organisation provides a holistic solution to clients, which includes detailed studies, specific technical solutions as well as multi-disciplinary projects satisfying a need for power, control, measurement and communication within an industrial environment.

Solutions perform as required, and on demand, and are engineered to meet a range of standards. The specific requirements differ in terms of client, region or country and tailored solutions are provided through consultation with DRA Global’s electrical control & instrumentation (EC&I) teams.

Focus is placed on delivering a technically sound working solution that is safe, functional, cost effective and delivered on time. Safety is inherent to electrical system design with most power design principals centred around risk and mitigating potential impacts. Typical solutions involve all the engineering and management services necessary to understand a particular problem, engineer a workable solution and to implement a solution that meets client needs.
