While drill and blast activities, rock bolting and shotcreting continue underground at Snowy 2.0, specialist crews operate the tunnel boring machines.
A major project component is also managing truck and light vehicle logistics.
This includes thousands of road safety inspections annually, more than 260 bus trips taking workers to and from site each week and about 780 heavy vehicle movements, such as the distinctive segment trucks carrying locally manufactured tunnel lining segments for the TBMs.
The security team work at the gatehouse controlling site access and scan more than 6,000 people and 3,000 vehicles each week.
There are 20 heavy vehicle convoys a day at Lobs Hole, all managed by traffic controllers.
So far there have been more than 130 escorted loads of very large components delivered to site, some more than 7m wide.
At the same time, Snowy Hydro has started drilling and blasting from the gate shaft to merge into the headrace tunnel alignment excavated by TBM Florence.
When completed, water will enter the headrace tunnel from the intake, on its way to the power station.
