Seawall erosion around Auckland ferry terminal
Erosion of the seabed and seawall around Auckland’s Ferry Building requires $1 million repairs.
Auckland Transport chief engineer Andrew Scroggins said divers discovered an increased amount of erosion of the seabed and seawall in front of the building at the bottom of Queen St in August.
A hole caused by the erosion was about 16 metres long and varied in depth from 20 centimetres to 1.2m, Scroggins said.
AT had been regularly monitoring the condition of the seawall due to its age. A further check two weeks ago showed ‘‘no further erosion’’, he said.
Repair work would start in about two weeks and take six to 10 weeks.
‘‘This will stop any further erosion,’’ Scroggins said.
Engineering firm Tonkin and Taylor had completed a preliminary stability analysis and confirmed that while there was no risk of imminent failure, they had recommended completing the work as soon as possible to prevent the erosion from continuing.
Some ferry services would be relocated and berth 1A will be closed during repairs.
However, full services are expected to run as scheduled.
Divers found a 16 metre hole in the building.
