Wharf and Harbour investigations and designs require adequate investigations to establish foundation soil parameters, water currents and tidal levels, boat berthing requirements, minimisation of eddies and adverse water currents.

Environmental effects need careful early consideration during a project, and strong technically based investigations to rebut any consent objections which may be costly and create time-consuming delays.

Projects include:

  • Te Hapaua Wharf
  • Golden Bay Cement Wharf
  • Marsden Point Wharf Conveyor
