In October 2020, A W Edwards was awarded the contract to construct the new Sydney Metro Crows Nest Station. The AU$370 project included the construction and fit out of the station, including two station entrances, underground platforms, retail space, public domain works and enabling works for future over-station developments.
Eighteen months earlier, Marr’s engineering team were approached by the end-client, Sydney Metro, during the front-end design phase to develop a craneage methodology for the project. Leveraging Marr’s experience in successfully delivering on a number of other Sydney Metro station projects where similar approaches to cut-and-cover method of station box construction had been employed, the goal was to align the craneage solution to Sydney Metro’s preferred precast and modular construction methodology.
As a result, Sydney Metro issued a considered and evaluated design for the construction tenderers with a suitable craneage solution built into it. Marr was subsequently awarded the heavy lifting contract by A W Edwards.
We work with our clients to find a craneage solution that works – no matter how big or complex the job is.
Following a competitive tender process, construction of the new Crows Nest Station came with a number of challenges including:
Working closely with Sydney Metro’s design and engineering team for 18 months during the front-end design phase allowed Sydney Metro to adopt their preferred design for manufacture and assembly (DfMA) construction methodology.
Taking buildability, time, and safety into consideration, Marr’s solution aligned the cranage with the construction methodology to help secure the construction program.
Using two of Marr’s M2480Ds installed within the station box, the bespoke cranage solution addressed the challenge of how to provide the heavy lifting capacity the project needed within the small space of the station box construction site. Our approach also addressed the other logistical challenges that came with the lack of space available for the delivery of materials to site and the handling of large precast and steel elements weighing up to 120 tonnes.
Marr’s expertise resulted in a cranage solution that:
