Results
Immediate mitigation of rockfall hazards on this critical rail corridor.
Rapid mobilisation enabled maximum utilisation of the shutdown period.
Quality and sequencing of work facilitated efficient remobilisation for subsequent phases.
Zero significant safety incidents, with client expectations for quality fully met
Project
Solution
Excavator-mounted drills worked below powerline clearance, with wagon drills used above 4m.
A six-person crew installed 75 ground anchors (3m deep), with ~276m² of mesh secured.
Grouting operations were sequenced alongside drilling and mesh fixing to optimise time.
Daily operations extended to 13-hour shifts to maximise productivity within the shutdown
Project
Challenges
Active train operations and overhead power line obstructions constrained drilling methods
Limited slope access and steep terrain increased complexity of anchor installation
A compressed eight-day possession window required accelerated delivery
Weather conditions included rain, wind, and high sunlight exposure, impacting productivity

Project
Overview
Geovert was engaged by KiwiRail to deliver slope stabilisation and mesh netting above the Johnsonville railway line in Wellington. The works targeted rock fretting hazards along a heavily trafficked passenger line, which had not experienced significant shutdowns in recent years.
Operating across two separate sites, the project was delivered within a strict eight-day Easter holiday possession, requiring highly coordinated construction methodologies to maximise outputs in the limited timeframe
