Description
Guidera O'Connor (GO) is an Australian privately owned company operating only within the Water Industry and specialising in the delivery of water/wastewater treatment and pumping projects comprising a complex mix of scope.
Having successfully delivered over 285 water projects since 2001, GO's Safety, Quality & Environmental management systems have evolved specifically based on water projects. As a result, GO are currently celebrating over 11 years LTI Free in addition to continued Federal Safety Commissioner Certification.
With an in-house detailed design and drafting team, GO offers innovative solutions during tender, design and construction phases. Unlike larger D&C firms who deliver projects across a broad range of industries, our personnel work full-time on water projects averaging 15 years within the Water Industry.
GO are an employer of choice with an average staff retention rate of 8 years employment with the company, and we place high importance on the health, safety, and well-being of our team, fostering a family environment to work in as our company continues to expand.
Operating all over Australia with particular expertise in remote and regional locations, it is GO's policy to engage LOCAL subcontractors where possible to deliver scope not performed in-house.
Our subcontractors consistently commend us for excellent subcontractor management and on-time payment, and our relationship with our subcontractors has largely contributed to the enhancement and development of their management systems resulting in safer and more effective construction site.
GO has built a solid reputation within the industry for quality workmanship delivered on-time delivery within budget.
We are a proud supporter of WaterAid and a member of the Water Industry Alliance (WIA) and the Australian Water Association (AWA).
