The Bella Vista factory that will make the concrete rings to line the North West Rail Link’s tunnels is nearly finished, the Minister for Transport Gladys Berejiklian said yesterday.
“Next month we expect it will start producing the first of 100,000 concrete segments – which will be assembled underground into 16,000 rings, to be installed as the tunnel boring machines move along the route,’’ Ms Berejiklian said.
“The North West Rail Link is on beudget and moving forward rapidly", she said.
Tunnel boring machines install the concrete tunnel lining rings as they dig and need a constant supply of about 100,000 concrete segments, which are used to create the rings.
Work on this factory at the future Bella Vista station, on the corner of Old Windsor Road and Celebration Drive, began last Christmas.
Ms Berejiklian said tunnelling consortium Thiess John Holland Dragados would recruit about 900 workers from western Sydney for the project in the coming months.
More than 140 tonnes of steel was used to build the frame for the Bella Vista factory, which is 147 metres long, 60 metres wide and 17 metres high at its tallest point.
The building has been enclosed with special acoustic cladding, which will allow the facility to make segments 24 hours a day without adversely impacting neighbouring properties.
All of the infrastructure needed to support the operation of the tunnel boring machines will be set up in the Bella Vista site, including sheds to handle the crushed rock from digging, conveyors, a water treatment plant and a cement grout plant.
