Engineering Compliance Essentials

  • TAO accreditation is essential for NSW rail contractors (AEO legacy) Australasian Railway Association+12compliancecouncil.com.au+12MU Group+12
  • Professional Engineer registration: RPEQ (QLD), CPEng or RPEng (other states)
  • National railway safety compliance: ONRSR certification
  • Infrastructure owner approvals: TfNSW, VRIOGS, PTA, etc.
  • NER compliance: for projects involving high-voltage electrification and grid interfaces
