Hydro Tasmania has appointed Hall Earthmoving to upgrade the Edgar Dam when works commence this year.
The upgrade works will enhance the dam’s ability to withstand movements in case of extreme weather events, including earthquakes.
The Edgar Dam is part of the Gordon-Pedder hydropower scheme which delivers up to 13 per cent of the state’s power and it is the largest water storage in the country. The dam’s capacity helps drought-proof Tasmania’s energy system.
Hall Earthmoving was established around four decades and remains a local family-owned business.
“We’re very happy that we’ve got this project. Working for Hydro Tasmania in this capacity has been a long-term goal of the business,” director of Hall Earthmoving Chris Hall said.
“The Edgar Dam project is something I’m very passionate about, my team’s very passionate about, and I’ve got a great mentor in my father.”
The project involves significant attention to environmental controls to ensure the Tasmania Wilderness World Heritage Area that surrounds the work site protected. The project has also met the Federal Government’s environmental requirements.
Measures include regular wash down stops for vehicles and machinery, only driving at certain times, downward facing dim lights and low noise emissions at night.
“It’s a big task but we feel confident because we have experience working in these kinds of areas, like on the West Coast, and understand how remote and sensitive that environment is,” Hall said.
The Edgar Dam campground and boat ramp will be closed during the upgrade works, which are scheduled to finish in mid-2026.
“We’re fortunate to have a local family-owned business that can carry out technical works of this scale right at home in Tasmania,” said Hydro Tasmania’s executive general manager of assets and infrastructure Jesse Clark.
