New Kangaroo Point Green Bridge: A Feat of Engineering

The construction of the new Kangaroo Point Green Bridge has reached a significant milestone with the successful installation of a 95-metre-high tower mast.

The operation was carried out by Marr’s heavy-duty tower crane, a 330-tonne Favelle Favco M2480D, which was installed on a platform in the middle of the Brisbane River.

The crane, equipped with a 64-metre jib, can lift its maximum capacity at a 15-metre radius, or take 100 tonnes to a 45-metre radius with a hook height of around 130 metres. This impressive lifting capacity enabled it to hoist the 25-metre-high, 180-tonne prefabricated steel masthead to a height of 95 metres.

The mast is the heaviest lift to be undertaken on the project, where the crane has already completed more than 10 major lifts during the first 12 months of the job.

The contract to build the bridge was awarded in 2021 to Connect Brisbane, a Besix Watpac led consortium. The consortium involved Marr at an early stage in the design phase, to develop a lifting strategy that supported their preferred construction methods for the project.

Project director, Rowan Riggall, praised the in-house engineering team for identifying the M2480D as the most suitable crane in the Australian market capable of lifting the fully assembled masthead.

Managing director, Simon Marr, highlighted the benefits of modularised construction with fewer, heavier lifts, stating it not only helps to deliver a safer, more productive site, but also allows the client to share the economic benefit delivered by the project.

The new bridge, an initiative of Brisbane City Council, will be an iconic landmark destination connecting Brisbane’s Central Business District with the eastern suburbs. At a length of 460 metres, the bridge will be among the longest span cable stay pedestrian and cycle bridges in the world. Construction is due to be completed in 2024.

More than 240 metres of the Bridge’s spans have been installed, passing the halfway mark across the Brisbane River. The cost of the project was initially estimated at $190 million but has been revised a few times and is now $299 million.

This project represents a significant achievement in engineering and construction, and is a testament to the innovation and dedication of all parties involved.
