Automation & Control

We have designed and delivered SCADA & process control systems to the heavy industries since GPA’s formation in 1987. The majority of installations have been in remote and rural areas, with monitoring and control facilities established in an operator’s head office commonly located in a capital city.

We have completed numerous projects for processing plants ranging from very simple, to more complex plants, with thousands of monitoring and control points. We also have significant, long-term experience, providing maintenance and operations support for PLC, RTU and SCADA systems.

GPA has experience designing PCS systems using all of the major vendor control systems. GPA is independent of the equipment providers thus ensuring our clients receive the most appropriate product selection and solution for their particular needs and budget.
