Wooden scaffoldings will help rebuild South Australia after floods
New wooden scaffolding will be used to help rebuild a flooded suburb after the South Australian Government announced it would use a new, safer and faster type of concrete to help prevent a repeat of the flooding that caused a major collapse of the town.
The council has been forced to cancel plans for the reconstruction of the Riverview Heights, after a section of the creek that feeds into the area collapsed last year, destroying the town’s streets.
The Council of South Australian Governments (CASA) has been working on a new concrete-based material for the town since 2013, but only recently decided to move ahead with the construction of the new wooden scaffold, as the town was in “high risk” of flooding, the council said.
“The wooden scaffolds are designed to allow for safe passage across the creek, provide a safe barrier to the flooding and prevent the recurrence of flood waters,” the council’s executive director Mark Stadler said.
The wooden scaffells were installed in 2018 and have been used to build flood defences around the River View Heights in South Australia.
They were made from the same type of reinforced concrete used to protect the main road in Southport, and the new material is designed to withstand up to 60 per cent more pressure than traditional concrete.
The scaffolds will be tested by a third party, and then certified to meet safety standards.
The new concrete will be installed in October 2018, when the new concrete road will be opened.
The town of Riverview was evacuated and about 200 residents were ordered to leave after the creek began to flood.
The Riverview Road has since reopened, but a section has closed.
Mr Stadlers said the wooden scaffolded road was the most successful construction project in the town in recent times.
“Our construction of this road has had the highest safety and cost performance,” he said.
South Australia has a population of about 13,000, and more than 600 people were evacuated when the creek started to flood last year.
The state’s new Premier Mike Baird said the town would recover, and would be rebuilt “like never before”.
“Our thoughts are with those affected by the flooding, who will need to wait for the construction to commence,” he wrote on Twitter.
“There will be a period of time when there will be some minor repairs and repairs that will be completed before the river recedes.”
