Project
Solution
Developed a hybrid drilling and access methodology combining a 20-tonne excavator drill rig and a crane-suspended basket drill rig for areas beyond reach
Coordinated multiple work crews to maximise daily production and minimise project duration
Utilised a 100-tonne crane positioned within a dedicated traffic management zone to support simultaneous high-reach drilling operations
Implemented comprehensive safety systems recognised by client health, safety, and environmental advisors for their professionalism and rigour
Project
Challenges
Significant public disruption caused by the required permanent lane closure during works
Tight program deadlines driven by the need to reopen the route before the summer holiday period
Budgetary limitations that required careful resource allocation and efficient delivery planning
Project
Overview
n August 2022, a major slip occurred in Pukerua Bay, Wellington, severely affecting State Highway 59, a vital backup route in and out of the capital. With the summer holidays approaching, rapid remediation was essential to restore safe access. Geovert was engaged by the Wellington Transport Alliance to stabilise the benched slip surface following initial earthworks.
The scope included the construction of anchored shotcrete retaining walls, installation of sub-horizontal drains, and formation of concreted swales across the benches. Operating under strict timeframes and access constraints, Geovert delivered a fast-tracked slope stabilisation program that reinstated resilience to this key transport corridor.
