We partner with local subcontractors and they respond positively to our respect for them.


Guidera O’Connor delivers multi-disciplined projects for water authorities throughout Australia, and regularly partners with local subcontractors to maximise the economic benefit to the communities that we work in.

We engage local companies to undertake:

  • Earthworks and pipelaying
  • Concrete construction
  • Building construction
  • Electrical construction

We also support our local partners by providing hands-on training in the construction of water infrastructure and guide them to develop quality, safe and environmental management systems to meet the requirements of the Federal Safety Commissioner.

Our regular subcontractors love working with us because we:

  • Pay on time
  • Manage projects professionally
  • Provide a safe working environment
  • Involve our subbies in design decisions
  • Actively help to improve management systems
"Of the many companies we deal with, none have been more willing to assist and support us than Guidera O’Connor and due to our similar values and dedication to excellence in quality, safety and customer service the relationship has developed into a partnership where we celebrate and share our successes. They have always been open and constructive in feedback given regarding our tender submissions and works undertaken and we have established long term relationships with all their staff and other sub-contractors"

"With our company quite often struggling with cash flow, it was always a welcome outcome when you could deliver your invoice with one hand and take away the cheque with the other hand. This is the reason that Central Civil & Plumbing will only contract for GO in the private sector and no other company"
John Telfer Central Civil & Plumbing
"I have found all of the staff I have worked with from Guidera O’Connor have a great understanding of safety, quality and environmental requirements of the various sites we have worked on together. This information has always been passed on in a manner that ensures all personnel have a good understanding of the specific project requirements"
Peter Overton SEM Group of Companies
