Description
The Sydney Metro West – Central Tunnelling Package contract includes the delivery of twin 11 kilometre tunnels and excavation of five station boxes at Sydney Olympic Park, North Strathfield, Burwood North, Five Dock and The Bays. A crossover cavern at Burwood North and one of the two precast facilities at Eastern Creek where more than 70,000 concrete segments will be produced to line the twin tunnels.
Once complete this new underground metro railway will double rail capacity between Parramatta and the Sydney CBD, link new communities to rail services and support employment growth and housing supply.
Rating Highlights

| Climate Change Adaptation | Cli-2 | The Project achieved a verified level of 3 with a score of 2.77.
The Project identified four medium climate change risks related to intense and extreme rainfall, flooding events, increased sea levels and increased frequency and intensity of extreme heat events. To account for the future risks, modelling has been undertaken to characterise the climate change risks. For example, a 10% increase in rainfall intensities has been modelled and additional allowance has been considered when additional impacts have been revealed by sensitivity analyses. |

Verified Innovations

| Multipoint Metering | 14/02/24 | | Innovative Technology or Process
World First |
The Project received 5 points for this World First innovation.
The Multi-point Metering for Tunnel Construction Energy Efficiency innovation involves installing and monitoring multiple electrical smart meters throughout the underground construction system. The data collected is then used to provide feedback to the tunnel supervisors on how to run the systems as efficiently as possible. This initiation is significant because underground construction works are large energy consuming activities on the CTP project. Previously, electricity bills were collated to capture gross electricity consumption. However, this innovation will now allow the individual equipment within the construction system to be measured and benchmarked for targeted energy optimisation. |
| Wfs Pilot | 14/02/24 | | Innovation Challenge | The Project received 1 point for piloting Wfs credits and 1.5 points for achieving a verified level of 2 for Wfs-1.
The Project was acknowledged and commended by the verifiers for the effort that has gone into the Wfs pilot. |
| Wfs-4 Sustainable Site Facilities | 14/02/24 | Innovation Challenge (IC-4) | The Project received 2 points for implementing the Site Facilities Requirements across all six sites offices. |
