Timothy Thompson

Senior Principal

Tim is a Registered Professional Engineer of Queensland with over 21 years of geotechnical investigation and design experience including deep and shallow bridge foundations, retaining walls, detention basins, rockfall protection, and slope risk assessment and stabilisation. Tim completed Bachelors and Masters degrees at Purdue University and has experience in the U.S., the U.K. and Australia. Tim spent more than 18 years at Arup before joining EDG in early 2024.

Tim is currently the National Chair of the Australian Geomechanics Society (AGS) and served as the Queensland Chair in 2016 and 2017. Tim led the development and implementation of the Queensland Geotechnical with an AGS colleague, and is currently undertaking part-time research at the University of Queensland.

Tim’s areas of expertise include:

  • Deep Slope engineering and risk assessment.
  • Earthworks and ground improvement.
  • Construction phase support for infrastructure.
  • Geotechnical applications of GIS.

Notable projects that Tim has been involved with include:

  • Cunningham’s Gap Reconstruction Project: Geotechnical Lead and Technical Advisor for longest continuous rockfall protection design for road infrastructure in Australia.
  • Caloundra Road to Sunshine Motorway Upgrade: Geotechnical Lead for project including approximately 22 new bridge structures, and related road embankments and culverts on Sunshine Coast.
  • Gold Coast Light Rail Stage 1: Geotechnical Lead for light rail founded first above hinterland rock, crossing over a landfill and running down a segment of coastline comprising sand of varying consistency.
  • Gordon Road Detention Basin: Design Lead for 5m high reinforced concrete basin wall designated as a referrable dam.
  • Port of Brisbane Port Drive Upgrade: Co-leadership of Geotechnical Design which included new 10m high embankments, reinforced soil structures, and associated ground improvement.
  • New Farm Riverwalk: Geotechnical Design Lead for new riverfront structure following severed flooding of early 2011 that washed away the previous structure.
  • Homebush Bay Bridge: Geotechnical Design Lead for 400m long segmental cantilevered bridge founded on driven steel tube piles through very thin layer of soft and contaminated soils over hard rock.
