Snowy 2.0 continues on schedule, with work to assemble the first Tunnel Boring Machine (TBM) set to continue at Lobs Hole over the Christmas period. The Tantangara worksite closed December 23 and was scheduled to restart January 4.
The first TBM was delivered in 125 cargo loads, but is now on site at Lobs Hole. Snowy Hydro said they are making “great progress” with assembling the TBM with tunneling work on the main access tunnel portal due to begin early in 2021.
Work on the exploratory camp at Lobs Hole is expected to be completed early in 2021. The camp is currently accommodating about 100 workers and will eventually have capacity for more than 300 onsite workers. Construction of the other camps will follow later in 2021.
Tunnelling from Tantangara is due to start next year.
“Snowy 2.0 works are progressing very well and according to our expectations, with 850 people working on the project, including more than 70 from the Tumut and Tumbarumba region and other local subcontractors,” said a spokesperson.
Earthworks at the portal for the emergency, cable and ventilation tunnel portal are also advancing, with 4,000 cubic metres of material being moved per day.
The second TBM is also on its way to the project, with several key parts already delivered.
Deliveries of oversized loads, which caused some road closures and delays earlier in the year, have now finished for 2020. No further disruptions to traffic are expected over the Christmas and New Years period in connection with Snowy Hydro’s work at the site.
The next TBM deliveries will begin in late January 2021. A spokesperson said some loads will require police and pilot escorts.
TBM delivery predictions are posted on the ‘Traffic’ page of the futuregenerationjv.com.au.
Snowy 2.0 works at Tantangara are also underway, including maintenance works on Tantangara Road, upgrades to Quarry Trail Road, preparations at the site for a worker accommodation camp and civil works for the temporary bypass tunnel and entrance to the intake structure.
Snowy Hydro confirmed that public access is being maintained at Tantangara Reservoir, although there will be some temporary restrictions.
