DEMAND FOR QUEEN’S WHARF CONSTRUCTION WORKERS
The Queensland Government have indicated the increasing demand for construction workers to deliver Brisbane’s $3.6 billion Queen’s Wharf development. The Government has launched a campaign to attain 2000 workers to excavate more than 450,000 cubic metres of material over the next 15 months to create a five-level basement for thousands of car parks at Queen’s Wharf.
Construction of the Queen’s Wharf diaphragm wall has begun. The wall is a 172-metre concrete wall which will create a watertight underground barrier between the Queen’s Wharf basement and the Brisbane River. Hundreds more construction workers will be recruited to deliver Queen’s Wharf as the project moves towards peak construction demand.
The construction of the diaphragm wall was an engineering feat rarely seen in Brisbane with more than 2,500m3 of concrete – enough to fill an Olympic-sized swimming pool – to build the diaphragm wall. The wall will have 28 panels running along the inside edge of Queens Wharf Rd to Margaret St to provide a watertight barrier. The 28 vertical panels are 800mm wide and are between 2 metres and 7.2 metres in length. To build the diaphragm wall, a guide wall is first dug, and a narrow vertical trench is then excavated and filled with bentonite slurry, which is a naturally occurring clay.
A steel reinforcement cage, up to 6 tonnes in weight and more than 20 metres in length, is then craned into the vertical trench, which is then filled with concrete to create the panels. The clay slurry is recycled and stored onsite during the works in large blue and yellow towers along Queens Wharf Road. Finally, the barrier wall will take around three months to complete. The remaining circumference of the basement will be secured with concrete piles and rock anchors.
Starting this week, tradies and companies interested in working on this project will be able to register their interest online. The launch of the website and advertising campaign for more workers has recently begun. The website will enable subcontractors, suppliers and individual tradespeople to register their interest to participate over the life of the Queen’s Wharf’s build. In addition, the Consortium will go live with an Industry Capability Network website, to capture what they expect will be thousands of varied expressions of interest to work-on and supply this massive, game-changing development. The fields targeted include; painting, steel work, glazing, metalwork, carpentry, roofing and hardware supply.
