Working on underground construction sites requires extremely compact and versatile machines. This need led Abyss Construction to choose Magni as their partner in the Sydney Metro renovation project.
The Sydney Metro is currently undergoing major upgrade work in several respects. The service is revolutionising how the capital travels, connecting Sydney’s North West, West, South West and Greater West to fast, reliable turn-up-and-go metro services with fully accessible stations.
The project involves three locations: Central Station, the Marrickville site and the Chatswood site. The main upgrade works on the central station project is the construction of two new underground platforms to accommodate Metro Train services and a new 19m wide underground concourse. At Chatswood, a new service building called Northern Dive Services is being built to aid with the operation of the new metro trains service along with the finalisation of the tunnel fit out. Finally in Marrickville, the company is building the new Southern Sydney Metro trains facility.
The current package of works in Sydney’s Central station commenced in January 2022 and was 90% complete as of May 2022, whereas in the Chatswood they started in early July 2022 and was 30% complete as of early August 2022.
Abyss Construction took over the three sites and decided to use an RTH 6.26 and an RTH 7.26, both supplied by Allift, Magni’s local authorised dealer for the eastern region of Australia.
Currently in Central Station, the RTH 6.26 equipped with a 6-ton hook is busy completing a demolition package which involves lifting 4.7t concrete segments (2.2m x 1.5m x 0.47m reinforced blocks) whilst new platform canopies are being fitted overhead. Moreover, the machine has been used to lift over track slab segments (2.4m x 2.4m x 0.3m) weighing 3.9t. Items were picked and carried to load trucks at other side of the site.
In Chatswood, the machine is installing and stripping prefabricated wall formwork for the construction of an 450mm thick, 80m long, 8.5m high reinforced concrete wall which is being built in sections to facilitate the assembly in an extremely tight working environment – between two live rails with a full concrete roof structure overhead. The RTH 7.26 together with the 2 ton jib made these operations faster and easier.
