Project Complications & Achievements

The project team overcame many redesign and environmental challenges and engaged with Cleanaway through the entire process to give constructibility feedback during redesigns and design proposals. The weather event in February 2022 caused significant flooding which stopped works to this cell. During this time, Shamrock Civil assisted Cleanaway and Brisbane City Council by mobilising an emergency clean up crew to assist with removing flood damaged goods from the 3000 streets impacted by flooding in Brisbane. Due to the location of the cell and access constraints, Shamrock Civil used specialist plant such as Moorooka trucks to cart and tip aggregate material over the leachate collection system as they are lightweight and easy to maneuver.
