M5 Tunnel WestConnex Contact Us

Sydney, NSW

Bitu-mill’s NSW and QLD profiling divisions were engaged to complete sandstone profiling in the new WestConnex M5 tunnel. With significant tonnes to be milled, WestConnex engineers were given the option of Leica 3D machine control for profiling. Bitu-mill’s in house Surveying team set-up the 3D system on two profilers ensuring level control was completed to maximise productivity and efficiency.

The works were completed over 24 hour shifts in a challenging environment.
