A New Approach to Co-operative Project Development: A Stormwater Perspective

The proposed MacKays to Peka Peka Expressway has seen a new approach to project alliancing, with the Alliance extending to cover not just owner/constructor/designer, but also the local District Council. Another unusual aspect is that, unlike the more usual alliance of a design/construction phase project, this alliance’s first task is to develop the concept, prepare a Scheme Assessment Report and AEE, and take the Project through an EPA process for designation and consenting. This has resulted in challenges and successes, as different drivers and standards are merged, and differing responsibilities are addressed.

This paper outlines the structure of the Alliance and how the project will be delivered with a particular focus on stormwater issues. It explores how the various relationships work, relative to the responsibilities of the different parties in this respect between the stormwater engineer, ecologist and Council asset manager. It looks at some of the issues around standards and how these have been addressed, and draws together some thoughts and learning from the experience of putting together such a cooperative venture.
