Project:Major cliff stability study at Tudibaring Headland, Copacabana NSW
Client:Gosford City Council
The investigation of the Tudibaring headland at Copacabana is an example of localised geotechnical mapping to identify the stability hazards of a particular area.
In this study, the firm was commissioned to study the geology of the headland, its likely state of stability and possible long term effects of any perceived instability on the nearby residential development.
The investigation included detailed geological mapping of the headland [using specially devised “slow descent” abseiling methods to permit photography and field sketching], with detailed advice subsequently being provided on both the headland stability and likely impact of cliff recession / instability on the residential development on the upper part of the headland.
Outputs of the study included specific guidelines [both in terms of footing designs and headland set-backs], for use by the Council in planning future development near the headland.
