Results
Approximately 5,700t of unstable rock safely removed from the slope.
95% of debris successfully contained by the barrier, protecting the road below.
Road remained open throughout works, minimising disruption to the public.
Improved long-term slope stability along a high-profile section of the Great Ocean Road.
Project
Solution
Temporary rockfall protection system constructed with anchored containers.
Scaling works using bars and airbags to safely release unstable rock.
Drilling and controlled breaking of rock into manageable sizes for removal.
Installation of DCP rock bolts for additional slope stability.
Project
Challenges
High-risk overhangs and block columns up to 100m above a live roadway.
Requirement to keep the road open during scaling operations.
Safe removal and management of 5,700t of rock.
Extremely challenging access for drilling and bolt installation.
Project
Overview
As part of the $53 million Great Ocean Road Resilience Project, complex rock removal works were carried out on the cliff face where the mountains meet the sea. To maintain road access during operations, a temporary protection system was designed and constructed using anchored containers.
Scaling crews then removed hazardous overhangs and block columns up to 100m above the road, with approximately 5,700 tonnes of rock safely taken from the face. Most of the debris was contained behind the barrier, minimising impacts on road users, while additional stabilisation measures included DCP rock bolts installed under difficult access conditions.
