The New South Wales government awarded the joint venture of Acciona Construction Australia – Ferrovial Construction Australia a AUD 1.96 billion (USD 1.46 billion) contract for Sydney Metro West tunnelling works.
The joint venture will tunnel twin 11 km metro railway tunnels, will perform excavation and civil works for five new stations and will construct a crossover cavern at Burwood North station and one of the two precast concrete factories at Eastern Creek. Under the contract more than 70,000 concrete segments will be laid along the twin tunnels and two access shafts at Burwood North and The Bays will be constructed.
The tunnelling contract is expected to be completed in 2025.
The Sydney Metro West tunnelling will begin immediately to deliver 11 km of twin metro rail tunnels between Sydney Olympic Park and The Bays, which will be served by stations at the Bays, Five Dock, Burwood North, North Strathfield and Sydney Olympic Park. The joint venture will launch a TBM at The Bays Station site and a TBM at Sydney Olympic Park Station site.
Sydney Metro West will double rail capacity between Greater Sydney and the Sydney CBD, with customers able to get from Parramatta to the Sydney CBD in around 20 minutes on a fast, safe and reliable driverless metro train.
Acciona Construction Australia and Ferrovial Construction Australia joint venture was awarded the first of three major tunnelling contracts after a competitive tender process involving three shortlisted companies.
In August 2020, the government unveiled the shortlisted consortia for this Central Tunnelling Package.
The remaining two tenderers John Holland, CPB Contractors and Ghella Australia joint venture (JHCPBG JV) and Gamuda and Laing O’Rourke Australia joint venture (GALC JV) will bid for the Western Tunnelling Package, with the successful tenderer awarded a contract to build 9 km of twin tunnels between Westmead and Sydney Olympic Park. This second major contract is expected to be awarded by the end of this year.
Sydney Metro has also begun the process to appoint its third major tunnelling contractor for the Eastern Tunnelling package. This contract for tunnelling between The Bays and Hunter Street in the Sydney CBD is expected to be awarded by late 2022.
