Greg Hackney

Greg is a founding Director and Senior Principal with EDG Consulting based in Brisbane.  A Chartered Professional Engineer, a Registered Professional Engineer in Qld and Fellow of the Institution of Engineers, Australia, Greg is a Geotechnical Engineer with 23 years’ experience in the consulting engineering industry.  Over that time, he has demonstrated his ability to develop tailored project solutions for clients.  Areas of particular expertise include:

  • Design management, focussing on the integration and collaboration of geotechnical design teams with civil and structural design disciplines to deliver project outcomes.
  • Geomaterial assessment for use in engineering projects.
  • Slope engineering and remedial works designs.
  • Soft ground engineering.
  • Earthworks.

One of Greg’s major strengths is an ability to understand complex engineering issues and communicate those issues to the wider project team.  This aids in achieving a common understanding of issues and uncertainties, helping to define risk and risk management.

Greg has a broad experience base, having worked in a number of environments and roles.  After graduating in 1995 from UNSW with honours, spent nearly 10 years working as a geotechnical consulting in the Sydney region, where he worked on numerous projects including King Street Wharf, Thredbo, Penrith Lakes and numerous transport infrastructure projects.  Over that time, he progressed from graduate to Senior Engineer, and completed a Master of Engineering Science degree at UNSW in 2000. 

In 2003, managed an engineering consultancy covering the NSW mid and far north coast regions, based in Coffs Harbour.  He was involved in all manner of projects during that time, including the Shannon Creek Dam and access road construction and the Coffs Coast Resource Recovery facility.  In 2007, he moved to Brisbane to be the geotechnical Project Director for the Gateway Upgrade Project as a Principal.  Following delivery of that project, he was involved in numerous large scale infrastructure projects and tenders, typically in the Design Manager, Project Manager or Project Director role.  In 2014 he was promoted to a Senior Principal position.

In 2015, Greg, together with Ian Shipway and Garth Powell founded EDG Consulting.
