Two tunnel boring machines – 90 metres long, 15.6 metres in diameter and weighing 4000 tonnes each, have been selected to build Melbourne’s $6.7 billion West Gate Tunnel.
CPB Contractors, as part of the Rail Systems Alliance (RSA), has been awarded works by the Victorian Government in support of the $11 billion Metro Tunnel Project, with the $6 billion tunnels and stations contract also finalised this week.
The successful contractor will commence construction on the project next month, now expected to cost $6.7 billion – about $1.2 billion above its original estimated cost, with the Victorian Government finalising contracts on the project this week.
The West Gate Tunnel Project could worsen Melbourne’s traffic congestion, increase car dependency and should be rolled back, according to a new report from leading planning academics.
An international search is under way for a supplier to build the four Tunnel boring machines (TBMs) required to build Melbourne’s $11 billion Metro Tunnel.
