Auckland City Rail Link

Business case

In 2010 Auckland Transport needed a business case for protecting the corridor for the Auckland city rail link. While employed at AECOM, David Adams managed the business case and Bill Lee provided vital insights into the impact of transit infrastructure on urban regeneration.

The business case broadly followed the New Zealand Government Better Business case framework. We needed to document some of the early decision steps such as demonstrating that the city rail link was the preferred alternative. Chapters in the business case described the need for change , CBD transport constraints, the proposed solution, economic evaluation and implementation.

The economic evaluation compared forecast expenditure with forecast travel time savings based on the Auckland Transport modelling. In addition to travel time (mobility) benefits, the business case included urban economic benefits, namely the additional economic value from jobs in the CBD that become feasible with additional CBD transit capacity.

The link between transport and land use was further developed in the publication, Auckland, Connected .

Client outcome

The case for the rail link was disputed by the New Zealand Government but ultimately the Auckland Government decided to protect the city rail link land corridor based on the business case.
