Marr Contracting has installed two M2480D heavy lift luffing cranes after being awarded the heavy lift contract for construction of the Sydney Metro Crows Nest station.
Marr has worked on a number of other Sydney Metro projects, including the Sydney Yard Access Bridge (SYAB), redevelopment at Central Station, and station developments at Martin Place and Barangaroo. For this latest project, construction partner A W Edwards contracted Marr after working with Sydney Metro during the front-end design of the project.
“Our early engagement on this project has supported Sydney Metro’s desire to design and construct the new station by adopting a designed for manufacture and assembly (DfMA) construction approach. It’s essentially about taking a wholistic view to align the craneage with the preferred construction method, and then using this to secure the construction program with a safer, more-efficient and cost-effective solution,” said Marr’s managing director, Simon Marr.
Two of Marr’s M2480D cranes are able to work within the small confines of the station site, handling precast elements weighing up to 100 tonnes.
Simon Marr said: “The challenges associated with this project are largely to do with its location and where its construction schedule sits within the greater Sydney Metro project. Being able to work closely with the Sydney Metro team and have access to its engineering team during the design works was essential to developing a solution that took buildability, time and safety into consideration.” This stage of the process took 18 months to complete.
Construction on Sydney Metro Crows Nest station commenced in January 2021. Metro services are expected to be operational by 2024, with Marr’s scope of work at Crows Nest finishing in 2022.
