FLINDERS Power has passed the halfway point of the Northern Power Station demolition, with the scheduled completion date less than a year away.
The next stage of the demolition is planned for late August, while the northern boilers are expected to come down in late August to early September.
Flinders Power program director Brad Williams said the completion of the demolition is scheduled for June 2018, which will then be followed by a period of cleaning and exiting the site.
"The project is on time, on budget and being conducted safely," Mr Williams said. "We're really happy with the progress to date."
McMahon Services' PC 4000, the world's largest excavator, has been designed specifically for the demolition project.
Mr Williams said the excavator's specially-designed sheers can cut through the strongest of steel.
"The PC 4000 is the largest demolition excavator in the world, and also the largest set of sheers have been commissioned for this project as well," he said.
"One of the benefits is it can reach some of the taller structures that we have on site, so work can be conducted safely from a distance using a machine."
After ash clouds from the site engulfed the city in January, Flinders Power completed the process of covering the ash dam with dust suppressant.
The long-term solution of spreading topsoil over the ash dam is now in progress, with about 430,000 cubic metres of soil from the borrow pit moved across to the ash dam to cover 160 hectares to date.
Four of the five access fingers which allow the excavators to safely travel across the site have also been completed.
Flinders Power has commenced the revegetation of the dam, with the seeding of about 100 hectares completed and the remaining 80 hectares to be topsoiled in the coming weeks.
Mr Williams believes it is one of the biggest revegetation projects in the state’s history, with over six tonnes of seed collected.
“It’s coming along really well. We’re waiting on some rain to initiate germination,” he said.
“It’s certainly the biggest single event of seed collection in South Australia ... all our seed was collected within a 100 kilometre radius of Port Augusta, so the seed is natural and endemic to the region.”
More than 150 people attended a Community Open Day at the Power Station site on Sunday, July 30, as Flinders Power gave local residents a first-hand opportunity to see work completed so far.
