Marr Contracting’s M2480D tower crane has installed the final piece of the 95 m-tall mast centrepiece of the Kangaroo Point Green Bridge in Brisbane, Australia.
The BESIX Watpac-led consortium, Connect Brisbane, who is delivering the project on behalf of Brisbane City Council, engaged Marr early in the design phase of the project to develop a lifting strategy that supported its preferred construction methodology and addressed the challenges of constructing the 95 m-tall mast. A key challenge being how to construct the bridge mast while minimising potential impacts on the public ferries and private vessels that use the Brisbane River.
According to BESIX Watpac project director, Rowan Riggall: “Our in-house engineering team was instrumental in identifying this crane at tender phase as the preferred lifting solution for the project. After comparing barge crane and tower crane options, the team confirmed the M2480D was the most suitable crane in the Australian market capable of lifting the fully assembled mast head.”
The M2480D heavy lift luffing (HLL) tower crane was used with a 64 m-long boom, installed on a platform in the middle of the Brisbane River. The lift was the heaviest to be undertaken as part of Marr’s scope of work, which included more than 10 major lifts and general construction lifting requirements over a period of 12 months.
At a length of 460 m, the bridge will be among the longest span cable stay pedestrian and cycle bridges in the world. Construction of the Kangaroo Point Green Bridge is anticipated to be completed in 2024.
