The construction process on the next Sydney Metro precast facility is undergoing at Eastern Creek.
Over 70,000 precast concrete segments required to line the Sydney Metro West twin tunnels from The Bays to Sydney Olympic Park, will be manufactured by the bespoke facility at Eastern Creek.
The shed is 27m wide, 175m long and almost 12m at its highest point. The amount of dug material from the nearby Eastern Creek Speedway is more than 31,000 tons and has been reused at the facility site, minimizing cost and landfill on both sites.
To begin stockpiling the segments ahead of tunneling, the precast concrete segment facility is planned to be operational by the end of the current year.
While it is due to operate 24 hours a day, seven days a week, two other facilities will be constructed at the same location to service the other two stages of Sydney Metro West.
Including three tunneling contracts, the project is a part of Sydney Metro, Australia’s largest public transport endeavor.
Building of the twin 11km tunnels for the central section of the Sydney Metro West Line, is up to a joint venture among Acciona and Ferrovial, whereas the Gamuda Australia and Laing O’Rourke Consortium in order to deliver 9km of twin metro rail tunnels between Sydney Olympic Park and Westmead has the Western Tunneling contract.
The determined date for granting the contract of the third tunneling package, which is the Eastern tunneling between The Bays and Hunter St in Sydney’s CBD is later this year. The shortlisted consortia are: Acciona Construction Australia and Ferrovial Construction joint venture (AF JV); Bouygues Construction Australia, Vinci Construction Grands Projets Australia and Soletanche Bachy International joint venture (BV JV); and John Holland, CPB Contractors and Ghella joint venture (JCG JV).
