We deliver our work, manage our projects and fulfil our contracts using the skill and commitment of over 1,500 Zinfra employees, nationwide.

Living our culture of Safety First is imperative as we are often seen working in high density, urban locations, requiring a high level of interaction with the local community. Safety assurance is achieved through ongoing work groups, change programs, strong leadership and an innate understanding of safety.

Our clients also benefit from our engineering capability and our processes, which have been recognised through our status as an Authorised Engineering Organisation (AEO).  The AEO status allows Zinfra to produce and undertake engineering solutions for TfNSW with a significantly streamlined assurance process.
