Sydney Metro West will support a growing city and deliver world-class metro services to more communities.

The Laing O’Rourke and Gamuda Australia and Consortium was awarded the AUD$2.16 billion contract to design and construct the Sydney Metro West - Western Tunnelling Package.

• Excavation for a services facility and crossover structure at Rosehill to allow provision for fresh air ventilation and emergency egress;
• Excavation of connecting tunnels, junction caverns and tunnel portal from the Clyde dive site;
• Earthworks, retaining structures, drainage and utilities corridor for the Clyde Stabling and Maintenance Facility;
• Excavation and civil works for Parramatta and Westmead metro stations;
• A segment manufacturing facility at Eastern Creek constructing over 60,000 segments to line the twin tunnels.
