Downtown Ferry Terminal seawall repair

Auckland Transport is repairing erosion (scour) to a section of the Quay Street seawall at the base of the Downtown Ferry Terminal area.

Project status: Under repair from 9 October 2017
Project zone: Central

Divers discovered the scour during a regular inspection of the seawall in August 2017. It is 16 metres long and varies in depth from 0.2m to 1.2m.

AT has brought in expert geotechnical engineers, who are familiar with the seawall, to develop a design for the repair work and to prevent further recurrence.

The engineers have confirmed there is no suggestion of any imminent failure of the seawall or any public safety risk.

The repair work has been given priority to prevent any further damage.

Work dates

Work will begin on 9 October 2017 and is expected to take approximately 6 to 10 weeks to complete.

We are targeting completion before the busy summer holiday period, however, underwater works are complex and we will ensure enough time is taken to complete the repair safely.

Latest updates

Week one update

The first week of work on the seawall has progressed smoothly with the contractor, STF Limited, securing the site and starting preparatory operations.

These have included closing Pier 1A to establish the site and driving 5 timber piles into the seafloor. These piles will support a silt screen which will protect divers when they are working in the water on the seawall.

Timber hoardings to protect the public are being erected around the site. This will be finished early next week.

Barges, a crane barge, and tug vessels have also taken up camp on site in readiness for construction work beginning next week.

Measurement tools to monitor and measure the seawall, sea bed, and Ferry Terminal building have been set in place. This allows on-going strength testing of the seabed foundation and seawall. It also sets benchmarks which allows detection of any structural movement during construction.

The week ahead

This week, STF will begin removal of barnacles on the sea wall in readiness for the first dive operations. The dive team will be on site, commencing preparatory work and undertaking surveying.

Ferry service changes

The closure of Pier 1A on Monday saw Bayswater and Birkenhead services shifted to depart from Pier 1C, and some evening Half Moon Bay services leaving from Pier 2B.

The first week of service changes has progressed well with minimal impact on services and no customer complaints received.
