How good is Sydney Metro? So good, thanks to DMG
If you haven’t taken a ride on Sydney’s newest Metro line, then you are missing out.
Sydney Metro is Australia’s biggest public transport project, changing the way Sydney moves. And it might be surprising to people outside the city, but it’s developed a huge fan following.
We might be biased, but we think that’s due, in part, to DMG’s successful works on the amazing Victoria Cross, Martin Place, Pitt Street (Gadigal) and Waterloo stations.
As a result of DMG’s work to date, they’ve been tasked with an important role in the city’s next big project Sydney Metro – Western Sydney Airport line.
The team are currently working on the Orchard Hills and Bradfield Metro Stations – completing what are known as station boxes – including the formwork, steel fixing, pre-cast segments installation, and concrete pumping, placement and finish for each station.
The team have also been successful in winning the Airport Portal Dive Site. Tunnel portals are the transition points for the rail track from the surface to below ground. The Airport Portal Dive tunnel will be around 140 metres long, with the structure starting around 400 metres out from the Airport Business Park station.
By the numbers
Across the two stations and portal dive:
- 79,000 cubic metres of concrete, including ENVISIA® lower carbon concrete
- 110,000 square metres of formwork
- 17,500 tonnes of steel reinforcement.
A project like a metro station is certainly unique with a special set of engineering considerations. “The unique formwork and steel reinforcement you need in a Metro station, means that we need to arrange temporary engineering works upfront so that we can assess the load paths across the structure,” said DMG Project Engineer Krishaant Murti.
DMG Construction Manager Gaby Daher said: “Because of the amount and type of concrete and reinforcement that’s needed in a project like this, there are a lot of moving parts. Each pour needs to be coordinated with multiple partners and the placement needs to go smoothly. That’s where the DMG team really shines.”
DMG Sales Manager Graziano Barbaro added: “Thanks to Gaby Daher, Dylan Purcell, Krishaant Murti, Marco Gidaro and everyone involved from the very beginning of these works, during tendering through to executing, – it’s been a true DMG team effort.
Did you know?
The Western Sydney Airport line is designed to accommodate up to 7,740 passengers per hour in each direction.
It is expected to become the ‘transport spine’ for Greater Western Sydney, connecting communities and travellers with the new Western Sydney International (Nancy-Bird Walton) Airport and the growing region.
