Results
Successful delivery of large-scale slope protection and stabilisation works on the TSRC East Section.
Enhanced safety and resilience of new highway cuttings through integrated geotechnical systems.
Works completed to program using a mix of conventional drilling rigs and specialist rope access teams.
Contribution to the safe and efficient opening of a nationally significant freight corridor.
Project
Solution
Installed over 20,000 linear metres of GRP ground anchors and 84,000m² of GREENAX matting for erosion protection.
Constructed slope stabilisation systems including 2,000m of double corrosion protection (DCP) anchors, 2,000m³ of shotcrete, and 1,500m of sub-horizontal drains.
Delivered ancillary support measures including berm reinstatement, dentition works, and crack sealing.
Utilised a combination of tracked production anchoring rigs, mini piling drills, and rotary/percussive drill masts on excavators.
Deployed rope access crews for drilling and installation in areas inaccessible by plant due to earthwork constraints.
Project
Challenges
Large-scale highway infrastructure project with national freight significance.
Requirement to protect extensive new cut batters in highly variable ground conditions.
Complex program involving multiple stabilisation systems across large work areas.
Restricted access in steep sections where conventional equipment could not operate.
Strict safety and environmental compliance requirements on a high-profile public project.
Project
Overview
The $1.6 billion Toowoomba Second Range Crossing (TSRC) is a 41km heavy vehicle bypass route jointly funded by the Australian and Queensland Governments to improve freight efficiency, safety, and amenity by diverting heavy vehicles away from Toowoomba’s CBD. As part of the East Section delivery, Geovert was appointed by Nexus Delivery to provide geotechnical support to new cut batters.
The works included extensive slope protection, stabilisation, and ancillary treatments, delivered using a combination of advanced drilling rigs and rope access techniques in challenging terrain.
