As part of the Wynyard Edge Alliance, Tonkin + Taylor guided the redesign of historical oil terminal properties to serve as syndicate bases for the 36th America’s Cup sailing regatta, along with the construction of breakwaters, inner harbour dredging, wharf renovations, construction of syndicate public access ways, marine/port accessory structures, and services installation.

The project scope expanded to include additional endeavours such as ferry terminal relocation, the Silo Park Extension redevelopment, and the creation of a 1 km main trunk stormwater line and outfall. Despite the project’s conflicting priorities, including a constrained timeline, an immovable deadline, and a challenging budget, the team utilised agile processes with parallel workstreams to deliver results.

Detailed designs were developed in parallel with alternative options to enable changes and optimisation as the project progressed.

Throughout our involvement, Tonkin + Taylor played a vital role in the successful delivery of the project, working closely with the Wynyard Edge Alliance and other stakeholders. Our design, construction, and project management expertise ensured that the historical oil terminal properties were transformed into functional syndicate bases for the 36th America’s Cup regatta. 

Additionally, our contributions to the construction of breakwaters, dredging, wharf renovations, and other infrastructure elements further enhanced the site.

Despite the challenges, the team remained committed to delivering high-quality results while meeting the project’s constraints. The collaborative approach and agile processes allowed for flexibility, effective decision-making, and the successful completion of the project’s objectives.

Overall, the Wynyard Edge Alliance project is a testament to our ability to navigate complex projects and deliver innovative solutions within tight timelines and budgetary limitations.
