Technical Staff

Guidera O'Connor employs 100 qualified personnel who all work solely on Water Projects. We maintain extremely low levels of staff turnover which allows us to retain a large base of knowledge and experience for the benefit of our clients.

The staff pool includes a mix of Project Managers, Engineers, Drafters, Safety Professionals, Site Supervisors, Tradespeople and Project Support staff. The experience retained in our team ensures that our projects are delivered safely, on time and in accordance with appropriate technical standards.

Our key team members work in the roles they enjoy; they have authority, are involved in making decisions and help to determine strategies. We develop our staff from within, employing graduates and training them to become specialists in the water industry.

We have a professional yet social team culture that allows staff to work together and play together.

Reconciliation Action Plan (RAP)

Guidera O’Connor has developed a Reconciliation Action Plan (RAP), a strategic document that supports our business plan. It includes practical actions that drive GO's contribution to reconciliation both internally and in the communities in which we work. With RAP, we are engaging in respectful relationships and creating meaningful opportunities with Aboriginal and Torres Strait Islander people.

When developing the RAP we undertook a survey of all of our staff to gauge existing awareness of Aboriginal and Torres Strait Islander culture to gain their input. This process has led to partnerships with various Aboriginal and Torres Strait Islander companies, and more than 3% of GO’s employees now identify as aboriginal. You can view our RAP document here.
