In
June 2016, CPB Contractors, with joint venture partners John Holland
and Dragados, officially completed tunnels and station civil works for
the $8.3 billion Sydney Metro Northwest project (Stage 1 of Sydney
Metro) seven months ahead of the contract program.
The joint
venture was awarded the $1.15 billion contract in June 2013 to build the
15km twin tunnels between Bella Vista and Epping (at the time,
Australia's longest railway tunnels), as well as the civil works for
five new stations and two services facilities.
