Rangitoto Island Wharf Replacement
Department of Conservation
Hauraki Gulf, Auckland, New Zealand
Set in a pristine marine environment Rangitoto Island is one of Auckland’s most iconic landmarks. Department of Conservation identified the need to replace the existing wharf on the island as access to the old wharf facilities was limited by tidal flow and allowed for only one berth.
Calibre Consulting provided design and costings for a new wharf that could cater for both larger and more vessels. Our team’s design included a number of pre-cast elements to minimise the amount of onsite concrete pours. Hollow concrete filled steel piles were also used to accommodate the varying depths of the underlying rock.
Protecting the natural land and water environments was a paramount consideration in designing the new wharf. Working within the restrictions imposed in the Coastal Marine Area, along with accommodating the commercial and private boat operators during construction, contributed to the success of this unique project.
