Sydney Metro West Tender

ScopeThe proposed Sydney Metro West will work together with the existing T1 Western Line between the Sydney CBD and Parramatta which is expected to be overcrowded by the early 2030s despite ongoing upgrade works. The Government has yet to confirm the alignment or release a business case but it is intended that new stations will be constructed at key precincts along the route including Parramatta Sydney Olympic Park The Bays Precinct and Sydney CBD along with an interchange at an existing T1 Northern Line station - either Concord West or North Strathfield. Further stations are under consideration along this route.An initial delivery strategy for Sydney Metro West was released in April 2018 which comprised several packages including two tunnel packages Westmead to The Bays Precinct and The Bays Precinct to Sydney CBD.The Bays Precinct - Sydney CBD package would see construction of a circa four kilometre tunnel between stations at The Bays Precinct and Sydney CBD with the potential for an additional station at Pyrmont under consideration. Tunnelling works around The Bays Precinct would likely have to navigate the future WestConnex M4-M5 interchange at Rozelle and associated link to the proposed Western Harbour Tunnel.In December 2018 Sydney Metro released the base case delivery strategy which revised the scope of the tunnel contracts to make their size more equal. The Tunnel and Excavation East package extends the original The Bays Precinct - Sydney CBD contract to an intermediate retrieval site between the T1 Northern Line link and The Bays Precinct.
