  • Geotechnical investigations, analysis, and design services for a range of building (industrial, commercial and residential) and infrastructure projects
  • Infrastructure feasibility studies
  • Roads and railways including pavements, cut/fill embankments, bridges, tunnels, embankments, cuttings
  • Mines and dams and pipelines

Geotechnical Investigations and Assessments

  • Desk studies – including Gap Analyses and Due Diligence assessments
  • Walk Over Surveys – including site and asset inspections; geomorphological, geological and rock slope mapping; and hydrogeological assessments
  • Intrusive ground investigations – including planning, scoping, management and reporting of intrusive ground investigations in accordance with AS1726-2017
  • Foundation design recommendations including shallow and deep footings including driven and bored piles, piles test review
  • Retaining wall design options for all types of walls Soil/rock slope/cut face stability assessments, soil nails, rock bolts/dowels and anchor design and recommendations
  • Pavement investigation and pavement thickness design including in-house Deflection Test (Benkelman Beam testing)
  • Earthworks quality control testing, co-ordination of laboratory testing, and supervision and comprehensive reporting
  • Road and rail subgrade assessments
