CPB Contractors, in a joint venture with United Infrastructure, is making significant progress on the delivery of the Sydney Metro – Western Sydney Airport Surface, Civil and Alignment Works (SCAW), with nearly one-third of the 3.5-kilometres of elevated viaduct now complete.
Vishal Khosla CPB Contractors Project Director, attributes this milestone to meticulous engineering and the use of hundreds of locally-manufactured precast concrete segments.
Once complete, the viaducts will comprise of 84 massive piers, up to 12m high. These piers will support the more than 1,100 segments required to form the deck, that that will take metro services above ground between Orchard Hills and Luddenham.
"These reinforced precast concrete segments are crucial to the viaduct's structure," explains Vishal.
Each segment measures an impressive 10.85 meters in width, is up to 3.2 meters in length, and stands at 2.4 meters in height. With a varying mass, ranging between 45 and 65 tonnes, each segment, demands the use of specialised equipment and expertise to transport and install onsite.
CPB Contractors’ construction of this 3.5km elevated viaduct is a key component of the Sydney Metro SCAW project. Once complete, it will connect Orchard Hills to Luddenham and pass through several important areas, including Blaxland Creek, Patons Lane, and the Warragamba pipeline.
In a joint venture with United Infrastructure, a consortium of Western Sydney-based companies including Burton Contractors, JK Williams and Mulgoa Quarries, CPB Contractors’ delivery of Sydney Metro’s SCAW project includes:
- 3.5 kilometres of elevated viaduct at Orchard Hills and Luddenham
- 6.7 kilometres of earthworks for track formation

- A 20 metre long rail bridge within the airport
