Inland Rail is an important project to meet Australia’s growing freight task, improve road safety and help decarbonise our economy. Inland Rail involves enhancing approximately 1,000km of existing railway track and constructing 600km of new track passing through regional Victoria, New South Wales and Queensland.

The Illabo to Stockinbingal (I2S) project involves the construction of 37km of new rail corridor and
2km of upgraded track just east of Illabo and at Stockinbingal, NSW. This new section of rail corridor will provide a direct route from Illabo to Stockinbingal through to the existing Forbes line. This will bypass Cootamundra and the steep and windy Bethungra Range with its Bethungra Spiral.

The Western Harbour Tunnel will be the crucial second road crossing underneath Sydney Harbour, providing a western bypass of the CBD with twin three-lane tunnels to ease pressure on the Sydney road network.

Stage 2 includes tunnelling from the WestConnex Rozelle Interchange at Birchgrove to the Warringah Freeway at Cammeray. The original plans for an immersed tube tunnel were changed to a TBM methodology, with twin 1.5km drives under Sydney Harbour, to reduce impacts on the harbour and seabed. The Stage 2 scope also includes roadheader tunnelling and full fit-out of the tunnels.

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.
