Seawall ero­sion around Auck­land ferry ter­mi­nal

East and Bays Courier - - OUT & ABOUT - STAFF RE­PORTER

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.
