Infrastructure NSW’s vision to transform Darling Harbour was one of the largest urban regeneration and infrastructure development projects ever undertaken by the NSW Government.
For The Men From Marr’s and the Darling Harbour Live consortium led by Lend Lease, the project demonstrated how heavy lift cranes, predominantly used in large-scale industrial projects, could be successfully used on high density inner-city infrastructure projects.
Managing lifts of up to 100 tonnes on a redevelopment that was still in the process of final design approval added to the challenges of working on a congested urban site surrounded by light rail, public roadworks, existing buildings, additional construction work and the general public.
Working directly with Lend Lease and the DHL Consortium, Marr’s team developed a craneage solution that was flexible enough to accommodate the scale and variables that the project presented. One of the biggest challenges of the project was the installation of heavy concrete pre-cast elements, weighing up to 100 tonnes.
Introducing our heavy lift crane fleet allowed our client to build the project in a completely different way – with the ability to build the job in a sequence that suited their construction methodology, rather than being beholden to the limitations of the craneage. It also redefined how infrastructure projects can be constructed.
Our solution allowed Lend Lease to maintain their original program, despite the pressure of design changes throughout the project. By completion, 100 critical lifts for elements weighing between 10 and 100 tonnes had been completed without incident.
Let's talk about how we could add value to your project
We work with our clients to find a solution that works – no matter how big or complex the job is. And if the right crane doesn’t already exist, we’ll build one to suit the needs of your project.
