Search Underway For Mammoth TBMs

06/11/2017

An international search is underway for a supplier to build the four massive Tunnel Boring Machines (TBMs) that will build Victoria’s biggest ever public transport project – the Metro Tunnel. The four TBMs needed for the $11 billion project will be more than 100 metres long, weigh up to 1,000 tonnes and be custom-built to grind through Melbourne’s unique ground conditions.

It will take up to 18 months to build the mammoth machines before they’re tested and shipped in segments to Melbourne. Click here and au/32 for tunnelbuilder archive. Visit https://www.premier.vic.gov.au/search-underway-for-mammoth-tunnel-boring-machines/.
