What we do

Roughan & O'Donovan guides clients through complex environmental legislation and regulation to deliver projects that meet the sustainability standards of national and local government.


Our experience in undertaking complex Environmental Impact Assessments (EIAs) extends across a range of infrastructural projects, including bridges, roads and buildings.

  • Ensure a thorough approach to consultation and stakeholder engagement
  • Maximise environmental sustainability
  • Minimise unnecessary cost and delay
