When tower line circuits have been identified for refurbishment or replacement it is
necessary to make an assessment of the foundation condition. Traditional methods
involve invasive excavation to expose the foundation blocks for visual inspection.
This project will trial underground structure survey technologies already utilised in the
civil and geotechnical engineering industries to assess the condition of tower
foundations and compare with the findings of traditional techniques.
Due to the intensive labour and time effort involved it is normal practice when
excavating foundations to perform an assessment on a 10% sample of towers. The
objective with this non invasive technology is to enable all tower foundations to be
