Why have you revised the design?

As part of the Interim Project Alliance Agreement (IPAA) phase, the Alliance has been challenged to review the existing design, improving it where feasible, with regards to performance, constructability, safety, sustainability, and affordability. Revising the design is not unusual for this stage of such a large and complex project.

A review of the reference design was undertaken due to feasibility and safety concerns. This developed concept design is more efficient for all users, has greater safety and sustainability benefits, is more affordable, and is easier to construct. Providing a safe and reliable transport solution for all users is one of the primary reasons for upgrading this piece of critical infrastructure.
