Consultants Sinclair Knight Merz will release the report in mid-2003. The study will examine different route options, including tunnels: a two- or three-lane 4 km tunnel from Spit Road to the Warringah Freeway, bypassing Spit and Military roads; a 6 km tunnel from the Burnt Bridge Creek Deviation near Sydney Road, underneath the waterline past the Spit; and two tunnels, one from Burnt Bridge Creek to the Spit and the second from the other side of the bridge to the Warringah Freeway. Visit www.skmconsulting.com 51/02.  The four consortiums bidding for the 3.4 km Lane Cove tunnel project have been reduced to two after the groups headed by Transurban and Macquarie Bank have been eliminated. The remaining two candidates are Lane Cove Motorway consortium including Leighton Contractors and Deutsche Bank and Lane Cove Tunnel consortium including Thiess, Transfield and ABN Amro. Leighton Holdings has emerged a winner in the race for the contract through Leighton Contractors in the first consortium and its subsidiary Thiess and its share of Transfield Construction in the rival group.

The joint venture of Leighton, Dragados and Samsung has been selected as the preferred contractor to design and construct Sydney’s $5 billion New M5 Motorway. The New M5 tunnel, Stage 2 of WestConnex, Australia’s largest integrated transport and urban revitalisation project, is being delivered by Sydney Motorway Corporation (SMC), on behalf of the NSW Government.

The New M5 will run via tunnel from the existing M5 East at Kingsgrove to a new interchange at St Peters, improving east‐west corridor access between the Sydney CBD, Port Botany and Sydney Airport area and the South West.

The project will deliver 9 km of two‐lane twin tunnels with a capacity to operate three lanes in the future, motorway to motorway connections to the King Georges Road Interchange Upgrade at Beverly Hills, and a new interchange at St Peters. The twin tunnels will have a height of 5.3 m, reducing the risk of over-height truck incidents.

Subject to completion of the project’s approval process, major works are expected to commence in mid‐2016 and the New M5 tunnel is scheduled to open to traffic in late 2019. WestConnex is being delivered in three stages, with final completion scheduled for 2023. Visit http://www.westconnex.com.au/  and http://www.leightoncontractors.com.au/. 38/15.

The NSW Government shortlisted the following three consortia to deliver the mega project’s first two major tunnelling packages for the construction of the Sydney Metro West, from Greater Parramatta to the CBD. Due to the scale of this city-shaping mega project the tunnelling and excavation works have been separated into geographically-specific contract packages between Westmead and the Sydney CBD.

• JHCPBG JV - John Holland, CPB Contractors and Ghella Australia; • GALC JV - Gamuda and Laing O’Rourke Australia; • AF JV - Acciona Australia and Ferrovial Australia.

They will firstly participate in the Central Tunnelling Package, with the successful tenderer awarded a contract to build 11 km of twin tunnels from The Bays to Sydney Olympic Park.

The remaining two tenderers will then bid for the Western Tunnelling Package, with the successful tenderer awarded a contract to build 9 km of twin tunnels from Westmead to Sydney Olympic Park.

The successful tenderer for the Central Tunnelling Package will not be eligible to be awarded the Western Tunnelling Package, driving greater competition in the delivery of Australian tunnelling infrastructure. Sydney Metro West will double rail capacity between Greater Parramatta and the Sydney CBD, transforming Sydney for generations to come.

Subject to planning approval, work on the project is expected to start in The Bays later this year, with the first of four mega TBMs expected to be in the ground before the end of 2022.

The Eastern Tunnelling contract includes:   

• 3.5 km tunnels from The Bays to the Sydney CBD;  
• A TBM launch site at The Bays where two TBMs will be launched towards Hunter Street; the TBMs will cross the harbour near the Anzac Bridge, before heading to the new Pyrmont Station and then under Darling Harbour before reaching Hunter Street Station in the heart of the CBD. 
• A turnback cavern to the east of the new Hunter Street Station, allowing trains to turn around before travelling back towards Parramatta;   
• Excavation and civil works for two new cavern stations at Pyrmont and Hunter Street in Sydney CBD;  
• More than 8,000 segments to line the tunnels.    

Preparations for tunnelling on this final section of the line will start next year, with 2023 gearing up to the be the year of tunnelling for Sydney Metro West. Work is already underway to prepare for construction of the twin tunnels between The Bays and Sydney Olympic Park, and between Sydney Olympic Park and Westmead. TBMs are expected to start work in early 2023.

The SSTOM (Stations, Systems, Trains, Operations and Maintenance) contract on the 23 km Sydney Metro - Western Sydney Airport project has been awarded to the Parklife Metro consortium, comprising of Plenary Origination Pty Ltd, Webuild SpA, RATP Development SA, Siemens Mobility Pty Ltd, Siemens Mobility GmbH, Siemens Project Ventures GmbH and Siemens Mobility Austria GmbH.   

The contract includes 12 new metro trains, six new stations between St Marys and the new Aerotropolis, core rail systems and the stabling and maintenance facility to be built at Orchard Hills.    

Parklife Metro will also operate and maintain the Sydney Metro - Western Sydney Airport line for 15 years after it becomes operational.   

The awarding of the final contract coincides with another significant project milestone, with Sydney Metro – Western Sydney Airport becoming the first rail infrastructure project in Australian history to commit to being certified carbon-neutral from the start of construction through to operation. All carbon emissions generated during construction and operation will be reduced and offset.   

Plenty of activity is already underway as part of this mega project, including preparations at the future Aerotropolis Station for tunnelling from the airport to the Aerotropolis site, which will commence in 2023. Visit https://www.sydneymetro.info. 50/22.
