Results
Foundation works completed safely and efficiently despite significant access and terrain constraints.
Project delivered two weeks ahead of schedule, allowing early progression to subsequent bridge construction activities.
Environmental impacts were minimised through controlled access methods and reduced footprint solutions.
The integrated delivery approach reduced program risk and maintained certainty for the wider construction team.
Project
Solution
Deployed a bespoke drilling setup using a 35-tonne excavator fitted with a 2-tonne drill rig on a boom extension to reach difficult locations.
Supplemented production with a 20-tonne excavator to provide additional drilling capacity and flexibility.
Configured equipment to achieve the required flared pile geometry with accurate control of drilling angles.
Utilised rope access techniques in areas where machine access was not feasible.
Delivered an integrated scope including micropiling, soil nailing and shotcrete under a single mobilisation.
Project
Challenges
Steep slopes and dense vegetation severely restricted access for conventional piling and drilling equipment.
The bridge’s narrow deck design required micropiles to be installed at flared angles, increasing technical complexity.
Precise control of drilling alignment was critical to meet structural load requirements in difficult ground conditions.
Environmental sensitivities of the golf course and surrounding bush required low-impact construction methods.
Project
Overview
Geovert was engaged by Oxcon to deliver micropiling works for a new bridge at Muriwai Downs Golf Course. The project required a foundation solution capable of supporting the bridge structure across steep, constrained terrain while minimising disturbance to the surrounding native bush and golf course environment. Given the bridge’s narrow deck geometry and the challenging slope conditions, the works demanded a high degree of drilling accuracy and carefully planned access methodologies.
