Melbourne Metro Tunnels

A metropolitan rail infrastructure project, consisting of twin 9km rail tunnels running below the Melbourne CBD in Victoria, Australia. It will run from South Kensington station (northwest of Melbourne City Centre) and South Yarra Station (south east of Melbourne City Centre), together with 5 new underground stations in the CBD, and 2 portal stations.

The background

  • Five new underground stations: Arden Station, Parkville, State Library, Town Hall and Anzac. Two stations will be directly connected to the City Loop at Melbourne Central and Flinders Street Station.
  • High Capacity Signalling to maximise the efficiency of the new fleet of High Capacity Metro Trains.
  • Train / tram interchange between Anzac Station and the Domain Interchange.

The benefits

  • The Metro Tunnel will create a new end-to-end rail line from Sunbury in the west to Cranbourne/Pakenham in the south-east, with high capacity trains and five new underground stations.
  • The Metro Tunnel will create capacity on the network to enable more than a half a million additional passengers per week across Melbourne’s train network to use the rail system during the peak periods.

Our clients’ role on project

A multi-billion dollar availability based Public Private Partnership (PPP) includes the design and construction of the twin nine-kilometre tunnels and five underground stations, private finance and the provision of maintenance and other services during the operating term.

A PPP model drives innovation, best practice and value for money on the project. In an 'availability PPP' the State Government provides regular payments to the private party for making the asset 'available' for use. For this package, that will mean making the tunnel and stations available for public transport operations and Victorians to use.

PPP works will be undertaken by our client, the Cross Yarra Partnership (CYP) consortium. CYP comprises Lendlease Engineering, John Holland, Bouygues Construction and Capella Capital.

CYP is to deliver Tunnel and Stations – including the main tunnelling works, five underground stations, station fit-out, mechanical and electrical systems and specific maintenance services for the infrastructure delivered by the package and commercial opportunities at the new stations.

Our role on the project

  • We forensically identified the sources of and then quantified the design / scope changes to the 5 “station boxes” and 2 portal stations, to support upstream “in contract” variation claims.
  • Our scope commenced from a starting point of a (then) current design, that was significantly different in scope from an earlier design against the 5 underground station “boxes” and 2 portal stations.
  • Our role was to then forensically research back the causes or contributing factors that led to the changes in design, to then quantify and cost those changes.
  • Our work was then used in negotiations to conclude agreements on the value of the in-contract changes.
