Sydney metro : New Southern Railway

Design and construction of a metro line as part of a Public-Private Partnership (PPP)

Underground Works

Australia, 1995-2000

General description

Carried out as part of a Public-Private Partnership, this turnkey 10-kilometrelong metro line, comprising 9 kilometres of tunnel and 5 new stations, connects Sydney city centre and Kingsford Smith
Airport. Due to significant geological variations along the alignment, several excavation modes were used, including roadheaders for the hard rock and a bentonite slurry shield for the 5,500-metre-section of soft ground beneath the water table. At the time of construction, this 10.72-metre-diameter slurry-shield TBM was one of the largest of its kind. As one of the major infrastructure projects intended for the 2000 Olympic Games, the line is now used by over 26 million passengers each year.
