America’s Cup 36 – Wavebreaks

No waves – and no farewell to the Cup.

Team New Zealand’s successful America’s Cup defence in 2020 rested, in part, on the back of the successful redevelopment of Auckland’s waterfront. For Brian Perry Civil, as a sub-alliance partner to the Wynyard Edge Alliance, the scope of works consisted of large-scale marine piling and structures, with a team of up to 50 on five different work fronts.

In this high profile project with a non-negotiable completion date, the BPC team delivered five wavebreaks as fundamental pieces of the marine infrastructure required.

A subsequent piece of work was also completed consisting of fendering and turning piles for relocation of the Sealink ferry facilities. The team also contributed plant and personnel for extending Hobson Wharf—as a base for the Luna Rossa team.

 Innovative methods and planning saw efficient, high frequency, variable motion hydraulic vibratory hammers deployed for most of the works. A jack-up barge over a floating one was also used to support the pile casings, reducing the rock embedment required to maintain stability during construction and eliminating the requirement for large disruptive impact hammers.

BPC was invited to help explore structural options and evaluate the time and cost of various alternatives, given plant and labour constraints, resource consent processes, and compliance requirements. This saw several experienced BPC staff working within the Alliance project office collaborating on constructible solutions, consenting submissions, and early procurement decisions.
