Chadwick Geotechnics, a subsidiary of Tonkin + Taylor Group, undertook all the drilling and test pitting for the initial geotechnical investigation of footings and pavements. A dedicated team of NATA-registered site testing professionals then conducted quality control testing on subgrades and pavements, proof rolling inspections, performed plate load testing when necessary, and conducted foundation inspections for each footing throughout the construction period, helping maintain construction quality and support reliable footing and pavement performance.
The project highlights included installing 149 wind turbines, constructing 110 kilometres of internal access roads, and managing complex geology, all while supporting the project’s delivery.
In response to the project’s technical requirements, the team conducted geotechnical and hydrogeological investigations, designed full gravity, anchored, and hybrid footings, provided geotechnical advice for four substations, used Plaxis 3D modelling for foundation analysis, developed innovative and sustainable pavement designs, guided subgrade improvements and winter construction, prepared earthworks specifications and technical advice, provided laboratory services, and performed pavement analysis for heavy components and crane lifts.
