North West Rail Link’s nearing next milestone

2 April 2014
The $8.3 billion North West Rail Link is approaching another milestone as work on the concreting factory that produces the link’s tunnel lining segments nears completion.

The factory is located at the Bella Vista site, which eliminates the need for thousands of concrete trucks on local roads.

Producing the tunnel

Special acoustic cladding encloses the factory so it can make segments 24 hours a day without adversely impacting neighboring properties.

Minister for Transport Gladys Berejiklian said that next month the factory should start producing the first of 100,000 concrete segments. These will be assembled underground into 16,000 rings, and installed as tunnel boring machines move along the route.

As the tunnel boring machine cuts through the rock, a ring is put into place while the machine continues moving forward. The tunnel boring machines will cut about 120 metres on average every week.

Already, the first of four tunnel boring machines is set to be in the ground by October.

More jobs

Tunnelling on the link will support about 900 jobs.

Tunnelling consortium Thiess John Holland Dragados is undergoing a massive recruitment operation in Western Sydney to source the project’s construction workforce.
