How we
work.
Self-Perform Plant Fleet
Le Gardenz operates an in-house fleet of graders, excavators, rollers, and paving equipment - eliminating subcontractor dependency and giving you programme certainty on critical path activities.
Remote Mobilisation
We have established FIFO frameworks and logistics chains for remote and regional delivery. Our Karratha and Darwin operational hubs support rapid site establishment in WA, NT, and remote QLD.
Environmental Stewardship
All civil works are delivered under our ISO 14001-certified environmental management system, with site-specific ERPs and erosion controls designed before a single machine turns soil.
Pilbara Regional Road Network Rehabilitation
Le Gardenz was engaged by a state road authority to rehabilitate 180 km of sealed regional road network across the Pilbara region. Works were delivered in extreme heat conditions (up to 52°C) using FIFO workforce rotations and night-shift paving operations to maintain material quality standards.
- 180 km rehabilitated over 14-month programme
- Zero lost-time injuries across 220,000 worked hours
- All paving works completed within 1°C tolerance specification
- Programme delivered 3 weeks ahead of contracted milestone
