The Sydney Metro WSA SBT project is the design and construction of twin 9.8km tunnels and station boxes connecting St Marys with Orchard Hills and the Airport Business Park with the new airport city centre, Aerotropolis (Bradfield).

The project provides a key transport connection to the new Western Sydney International Airport.

The works included TBM and roadheader tunnelling works, tunnel permanent lining, dive structures, and the excavation and support of 5 station boxes and 3 shafts.

The NSW Government is delivering Sydney Metro West – a new underground metro railway which will double rail capacity between Parramatta and the Sydney CBD, link new communities to rail services and support employment growth and housing supply. The Gamuda and Laing O’Rourke Consortium (GLC) is delivering the Sydney Metro West – Western Tunnelling Package. The project involves nine kilometres of twin metro rail tunnels between Westmead and Sydney Olympic Park, excavation for two new metro stations, a stabling and maintenance facility at Clyde, and a precast facility at Eastern Creek.

– Twin 9km tunnels from Sydney Olympic Park to Westmead
– A Tunnel Boring Machine launch site at Rosehill, tunnelling first towards Sydney Olympic Park and relaunched from Rosehill towards Westmead
– Excavation for a services facility and crossover structure at Rosehill to allow provision for fresh air ventilation and emergency egress
– Tunnel portal and dive excavation at Clyde Stabling and Maintenance Facility
– Earthworks, retaining structures, drainage and utilities corridor for the Clyde Stabling and Maintenance Facility
– Excavation and civil works for Parramatta and Westmead stations
– A segment manufacturing facility at Eastern Creek constructing over 60,000 segments to line the twin tunnels

The Sydney Metro West Central Tunnelling Package (CTP) is the design and construction of 11km of twin metro tunnels and station box excavation connecting The Bays Precinct and Sydney Olympic Park.

The works include tunnelling through complex geology, underground cavern excavation, and station box construction at The Bays, Five Dock, Burwood, North Strathfield, and Sydney Olympic Park.

The Sydney Metro West Eastern Tunnelling Package (ETP) is the design and construction of 3.5km of twin metro tunnels and station excavation connecting The Bays Precinct and Hunter Street in Sydney CBD.

The works include demolition and shaft and underground cavern excavation at both Pyrmont and Hunter Street, including complex permanent structural lining.

The first stage of the Suburban Rail Loop – SRL East – is a fully-tunnelled 26-kilometre metro corridor between Cheltenham in the South and Box Hill in the North. The line will include six stations, including new interchanges with existing heavy rail stations at Cheltenham, Clayton, Glen Waverley and Box Hill, with new stations at Monash and Burwood.

The Suburban Rail Loop Authority (SRLA) has separated SRL East into seven packages. Included in the scope of Works Package C is:

–  Tunnelling and cross passages over the 16-kilometre Cheltenham and Glen Waverley section, and;

–  Clayton and Monash station box excavations, including temporary retaining structures.

The TSD project is the underground and brownfield rail surface works associated with the design and construction of the new Cross River Rail. The 10.2km railway includes 5.9km of twin tunnels running beneath the Brisbane River and CBD with four new underground stations at Boggo Road, Wolloongabba, Albert Street and Roma Street.

The project also provides a new above ground station at Exhibition, a rebuild for seven stations between Dutton Park and Salisbury, construction of three new stations on the Gold Coast, delivery of two new stabling and maintenance facilities, and commissioning of a new world class signalling system.
