Council’s $650 million Kingsford Smith Drive upgrade project is steaming ahead, with piling works commencing, as the roadway is widened out into the Brisbane River.
Lord Mayor Graham Quirk said the next phase of construction works would involve hundreds of concrete piles being bored into the riverbed, in what would be one of the largest river piling projects ever to be undertaken in the city.
“Over the next 18 months, a five-storey high piling rig will install 200 piles up to 32-metres deep along the length of Kingsford Smith Drive, to support the road widening and new river walk,” Cr Quirk said.
“This piling phase, which is four times larger than the New Farm Riverwalk replacement project, will make use of two, 432 square-metre barges to transport the materials for piling across the river from a fabrication site in Morningside to the Hamilton construction site.
“Each pile will take up to three days to install, and require a total of nearly 6,000 cubic metres of concrete.
“The 83-tonne piling rig will insert a large steel tube into the riverbed, drilling out a core, which will then have a steel cage inserted and be filled with concrete.
“This bored piling method will reduce noise and vibration impacts during the construction stage for local residents.”
Cr Quirk said the piling stage would run concurrent to the installation of concrete ground protection mattresses which had been laid along the riverbed to prevent erosion.
“Around 400 mattresses will eventually be laid and are being fabricated on site and transported across the river via barge,” he said.
“A dedicated marine logistics facility at Morningside is serving as a base for fabrication and materials, which will minimise lane closures along Kingsford Smith Drive during this stage of construction.
“The marine logistics facility contains Australia’s second largest dry dock and a barge loading dock, to easily allow access for the 12 barges required for project construction.”
Cr Quirk said that once complete, motorists would benefit from 30 per cent cuts to travel times.
“Not only will this vital upgrade deliver better public transport, pedestrian and cycling infrastructure, it will also create a vibrant new entryway to our city,” he said.
“Council is getting on with the job of delivering the infrastructure needed to keep our city moving now and well into the future.”
