Production on the bespoke tunnelling segments has begun for the nine-kilometre twin tunnels from Sydney Olympic Park to Westmead for the Sydney Metro West Project.
More than 60,000 concrete segments will be produced at the Eastern Creek facility to line the tunnels, and 3,600 segments to line the spur tunnels, which will link trains with the Stabling and Maintenance Facility in Clyde.
The segments will be stored at the facility until they are ready to be transported to site and loaded onto a tunnel boring machine, which will install the segments to line the tunnel walls as it excavates. Six segments will be used to make up one ring around the tunnel.
The precast segments, each weighing approximately 3.8 tonnes, are produced in high-precision laser-cut moulds that are designed and customised based on the specific project requirements.
The segments are produced to the highest safety and quality standards and validated with state-of-the-art digital engineering tools to-the-millimetre precision.
Approximately 100 workers will be on site at any one time to operate and maintain the facility which will operate 24 hours a day, seven days a week.
Sydney Metro West will double rail capacity between Greater Parramatta and the Sydney CBD, linking new communities to rail services and supporting employment growth and housing supply.
