Primary 'Theme' impacted
Sydney Metro Northwest is Australia’s first fully automated driverless metro railway. A 36 km link servicing Sydney’s north-west, it includes eight new railway stations and an upgrade to five existing stations. The Operations, Trains and Systems (OTS) component of the project was delivered under a PPP contract.
Typically, infrastructure procurement decisions primarily focus on the construction phase at the expense of a whole-of-life approach. This frequently results in increased lifecycle cost and risks, poorer performance during the operations phase, less consideration of customer outcomes, and a lack of scope for bids to incorporate innovative solutions outside of those that reduce upfront cost.
The PPP procurement model adopted by the NSW Government for the OTS component of Sydney Metro Northwest focused on customer outcomes and used an output specification over the more traditional focus on the construction phase. This enabled bidders to incorporate innovative solutions into their proposals that had a whole-of-life focus.
In the case of Sydney Metro, the government reference design sought 8-car trains with five-minute headways. The successful consortium, Northwest Rapid Transit (NRT), proposed 6-car trains operating at four-minute headway during peak hours, while future proofing for 8-car trains. The proposal delivered the required output capacity (in terms of passengers per hour per direction) and an improved frequency for customers.

Results / impact
NRT’s proposal enabled fewer carriages to be acquired overall while still delivering the required level of service and having the same passenger throughput, as well as improved customer satisfaction and reduced upfront capital expenditure and ongoing maintenance costs.
Key lessons learnt
Considering the operations and maintenance of an asset in the design and procurement phase optimises the project’s whole-of-life costs and customer outcomes by encouraging a long-term view.
Using procurement models that focus on output specifications ensures a focus on whole-of-life and customer considerations by the contractor that are accounted for in tender evaluations, providing room for bidders to propose innovative solutions that meet the government’s requirements.
