Noosa Council has issued its largest ever reconstruction tender, for the restoration of the section of Black Mountain damaged in the 2022 floods.
The project will require 6000 cubic metres of concrete – the equivalent to two-and-a-half Olympic swimming pools – and 800 tonnes of steel to repair the landslide zone, which is as wide as a rugby league field and as deep as a five-storey building.
The tender documents were issued this week after design concepts were endorsed by the Queensland Reconstruction Authority.

Council’s infrastructure services director Larry Sengstock said it was hoped to have a contractor in place as soon as possible.
“It’s a significant milestone to issue this multimillion-dollar tender as engineers have grappled with the complexities and challenges of restoring such a significant landslip,” he said.
Tender documents show that construction crews will be required to drive more than 300 steel and concrete piles into the ground to create a solid platform to rebuild the road and stabilise the road area at depths of 5-25 metres.
“We still have a considerable amount of work to do but issuing the tender is a significant project milestone,” Mr Sengstock said.
“Given the significant engineering and market-based challenges, we remain hopeful of getting strong responses from major construction firms.”
Mayor Clare Stewart said it was positive to see the project reach this milestone.
“We appreciate the challenges faced by residents of Black Mountain and we have endeavoured to assist in as many ways as possible,” she said.
“The landslide is quite complex and we thank the impacted communities for their patience and willingness to adapt to the ongoing changes this disaster has created for them,” she said.
The tender period closes May 23.
