AUSTRALIA: Sydney Metro has shortlisted three consortia for the third of three main construction contracts for the 24 km Sydney Metro West line linking the city centre with Paramatta and Westmead.

The Eastern Tunnelling package covers 3·5 km of twin-bore tunnels from the intermediate station site at The Bays to the line’s Hunter Street terminus in the city centre, together with three station caverns and the eastern turnback tunnels.

The bored tunnels will run under Johnstons Bay to reach the future Pyrmont station and then below Darling Harbour to Hunter Street, where interchange will be provided to the north-south metro line and Sydney Trains suburban services at Wynyard and Martin Place.

The three shortlisted consortia include an Acciona-Ferrovial joint venture, a grouping of Bouygues, Vinci Construction Grands Projets and Soletanche Bachy International, and a joint venture of John Holland, CPB Contractors and Ghella.

Acciona-Ferrovial was awarded the Central Tunnelling Package in July 2021, covering the 11 km between The Bays and Sydney Olympic Park; it is expected to launch its first TBMs from The Bays before the end of this year.

The central package was tendered as part of a two-stage bidding process, under which the remaining shortlisted bidders John Holland/CPB/Ghella and a joint venture of Gamuda and Laing O’Rourke would go on to compete for the 9 km Western Package between Sydney Olympic Park and Westmead. This second contract is expected to be awarded shortly.
