CGC were engaged to undertake a Slope Risk Assessment of the cliffs at Point Cartwright in the vicinity of the  Lighthouse that stands at the top of the rock outcrop.

A temporary crane platform was required at the crest of the 25m high cliffs to facilitate planned maintenance and replacement of the RADAR installation on top of the lighthouse.

Due to the proximity of the crane to the crest of the cliff the slope risk assessment was required to assess the risk of slope instability as a result of lifting operations.

Civil Geotechncical Consultants utilised a combination of traditional slope mapping techniques and cutting edge digital mapping techniques to undertake the risk assessment.
