McMahon Services is delivering major civil utilities works on what is set to be the biggest infrastructure project ever carried out in South Australia, and we’re looking for experienced Civil Pipelayers to join our Civil & Infrastructure team.

Work is already underway and there are years of work ahead. This is a rare chance to put your skills to work on a project of real scale, laying large trunk water mains, sewers, stormwater and underground services that will help shape the future of this state.

You’ll work alongside experienced Supervisors, Engineers and civil crews, with robust leadership, high safety standards and plenty of room to grow your skills on large diameter pipework you won’t find on every job.

If you’re an experienced Pipelayer who wants steady work for years, a great crew around you and a project you’ll be proud to say you were part of, we’d like to hear from you. And when this job winds down, there are more McMahon Services projects to move into.
