The Eastern Creek Precast Facility was in the spotlight recently after Channel 10 visited the Facility. The project site forms part of the Sydney Metro West – Western Tunnelling package, operated by the Gamuda and Laing O’Rourke Consortium.

The visit showcased the Sydney Metro tunnelling supercentre, which is about 17 hectares, the equivalent of 42 football fields. The Eastern Creek Precast Facility comprises three huge sheds, including the Sydney Metro West – Western Tunnelling Package shed, and was purpose-built to support the construction of the new metro line that will connect Greater Parramatta to the Sydney CBD.

Thousands of precast segments to line the 24-kilometre Sydney Metro West tunnels are being manufactured and a total of 61,000 of 146,000 precast segments have been produced at the facility since it opened late last year, with operations continuing around the clock, six days a week.

Work deep underground to build the Sydney Metro West tunnels is powering ahead, with four of six tunnel boring machines (TBMs) in the ground.

Each 3.8-tonne segment is custom-made using the highest quality laser-cut moulds, which are then placed inside a curing chamber set at 70 degrees Celsius for up to six hours. Approximately 500 segments are produced at the facility each day and stored in the yard, before being transported to site for loading onto a TBM. The TBM then installs the segments to the tunnel walls as it excavates, forming the rings that line the tunnels.
