Specific aspects:
20,000 year old glaciers formations are now boulders stacked up to 400m high up the slope in several sections. Due to Snowy 2 requiring more lane width for huge plant/equipment, extra widening of the existing single road access track was critical. Engineers consulted with Spec Geo to design the following:
-Galvanised 38mm hollow bar drilled from 9m to 45m per bolt. A total of 20,000 metres installed.
-Custom temporary catch fences above each site supplied and installed by SG.
-Single twist high tensile mesh applied and tensioned to boulders.
-Coloured shotcrete applied in various sections .
Access: Pre cut single lane benches for all plant and equipment along a heavy utilised access road for construction of the Mighty Snowy 2.
