About Us

A highly experienced, multidisciplinary engineering and management firm, GPA has consulted and provided engineering, procurement and construction management (EPCM) services, since 1987.

We develop, engineer, and implement industrial scale projects across the oil & gas, defence, water treatment & distribution, mining & minerals, power generation & distribution, renewable energy and hydrogen sectors. With a commitment to providing quality assurance and maintaining environmental integrity, our people are highly qualified and additionally possess expertise to advise on project and risk management.

Our commitment to safety and the environment extends to our own business, and this is evidenced by the fact that GPA has never had a lost time injury within its workforce, or a reportable environmental incident in its 35 year history.

We are dedicated to best practice, and our people are active participants in many industry bodies including Engineers Australia, the AIE (Australian Institute of Energy) and the Energy Pipelines Cooperative Research Centre (EPCRC). By contributing in this way, we ensure that we remain on the cutting edge of developments in engineering, and that we can imbue these in our client work.

Although based in Australia with offices in Adelaide, Brisbane, Darwin, Melbourne, Sydney and Perth, GPA can support clients wherever they are located including rural or remote Australia, or overseas.
