The Perry O'Brien Engineering work ethic is to live by our creed “quod erat demonstrandum” / "demonstrated to be so", which simply translates in layman's terms to “that's the way you do it and the jobs done right”, and at the end of the day when this holds true, there will be some satisfied punters on both sides of the fence.

  • About us

    PERRY O’BRIEN ENGINEERING was established in 1997 as Earthpro Pty Ltd. Following a change of ownership in 2015 the new owners Robert Perry and Michael O’Brien decided to re-band the company in 2016 by putting their own names and reputations on the line.

    Perry O’Brien Engineering has extensive experience in the area of waste management having been contracted to numerous council and contractors, all who are leaders in waste management, to execute cell construction, capping or waste handling, together with varied civil construction works including roads, dams, stormwater, and services. Please refer to the following list of past and present projects. We have the capacity to execute contracts in excess of $10 million, with Quality, Environmental, Safety and Management systems to match.

    We are committed to providing a safe work place for our employees whilst providing a competitive high quality delivery of service to our clients. We understand that in order to achieve our goals there is a fundamental need for continuous improvement and training of our people. Our people are the extension of our vision and by putting time and training into mentoring and improving their knowledge, skills and self-confidence we can continue to build our name making it synonymous with safety, quality and competitiveness.

    The PERRY O’BRIEN ENGINEERING creed “quod erat demonstrandum” is a Latin term used by mathematicians over the centuries which means demonstrated to be so or I have solved the problem. We apply it in the field to mean “that's the way you do it and the jobs done right”. We believe this gives our company and focus in executing the works with pride.

    The company logo is a Uni-griffin which is a hybrid mythical creature cross between a lion, eagle and unicorn, a creature whose story like ours is still being written.
