Gulf Harbour - Hobbs Wharf/Seawalls

Hawkins Infrastructure’s work on the Hobbs Wharf sea wall, creating an extension to the marina at Whangaparaoa’s Gulf Harbour, illustrates the company’s commitment to sound environmental practice – a commitment recognised at the New Zealand Contractors Federation 2008 Environmental Excellence Awards.

Mitigating environmental risks on the 3.8 hectare site was critical on this demanding project, in particular preventing sediments from construction activity entering the harbour. As part of the detailed Environmental Management Plan, a number of precautions were undertaken prior to earthworks commencing, including perimeter bunds for stormwater diversion, geotextile-lined diversion channels, silt fencing, sediment ponds and a decant system.
