Project Description

Rob Carr Pty Ltd was sub-contracted to Managing Contractor, John Holland, for the Metro Tunnel Early Works to deliver realignment of the South Yarra Sewer near the Domain Interchange. RCPL’s scope of works included excavation of a new 2m diameter tunnel 20m under Melbourne’s busy St Kilda Road and live tram tracks, and excavation of two access shafts at Domain Road and another two in Albert Road. Using an 8m long Iseki Unclemole TBM, RCPL excavated a 163m tunnel from Albert Road to Domain Road, lining the tunnel with glass-reinforced plastic pipe to create a new section of sewer. This new section replaced a 100-year-old brick sewer pipeline so that construction of the new Anzac Station in the St Kilda Road precinct can commence. Works also included hand tunnels between the shafts, live tie-ins to the existing brick sewer, installation of GRP MH connectors, backfilling of the shafts and grouting of the old brick pipeline. The completion of the Metro Tunnel Project by 2026 will create space for more trains to run more often across Melbourne’s rail network. This will create capacity for 39,000 more passengers during each peak period, reduce road congestion and pave the way for future expansion of Melbourne’s public transport network.
