The NSW Government wants a builder for its Sydney Metro West project.

Transport Minister Andrew Constance has announced the tender process to build two twin tunnels between Westmead near Parramatta and the Bays precinct in Sydney’s CBD is now open.

The tunnels running from Westmead to Sydney Olympic Park and Sydney Olympic Park to The Bays will be part of a larger, 50-kilometre tunnel.

The Government hopes the project will create around 10,000 direct jobs.

“The construction of this mega project will create many thousands of new jobs and support families across Sydney,” Mr Constance said in a statement.

“These contracts will require tunnellers, electricians, plumbers, carpenters, concrete workers, truck drivers, labourers and security guards.”

The Sydney Metro West project aims to create an underground driverless metro railway to cut travel times to around 20 minutes between Parramatta and the city.

There are plans for stations at Westmead, Parramatta, Sydney Olympic Park, North Strathfield, Burwood North, Five Dock and the Bays Precinct.

The government has allocated around $6.4 billion for the project, but the final cost will not be known until a contract is signed.

Work should begin before the end of 2022.
