Auckland Transport has completed repairs to erosion (scour) found on a section of the Quay Street seawall at the base of the Downtown Ferry Terminal building.
This includes a major scour at the base of the Downtown Ferry Terminal Building near Pier 1A and a smaller scour adjacent to Pier 2A.
Project status: Completed
Project zone: Central
Divers discovered the scour during a regular inspection of the seawall in August 2017. It was 16 metres long and varied in depth from 0.2m to 1.2m.
AT engaged expert geotechnical engineers to develop a repair design which would also prevent further erosion. The repairs were the first of their kind in New Zealand and required a careful but flexible approach to assess the scope of work and install a customised design which met the unique requirements of New Zealand conditions. The successful execution of the repairs have laid the blueprint for future similar repairs, if required, to Auckland Transports seawall infrastructure.
There will be ongoing regular inspection of the wall including monitoring the repairs for corrosion, however it is expected the anti-corrosion measures taken will provide a 20-year corrosion life span.
Works begun in October 2017 have now been completed. Control of the work sites have been handed back to Fullers and normal Ferry service operations have resumed.

Auckland Transport is pleased to announce the repair to the scour on the seawall underneath the Downtown Ferry Terminal Building has been successfully completed.
Last week the 15-metre “elco-rock” sandbag was installed at the base of the seawall and filled with around 110 tons of sand, successfully completing the repair.
The hoardings have been removed and the public once again have a clear view of the ferry basin.

Progress at the base of the seawall below the Ferry Terminal building has been excellent over the past few weeks.
All of the protective stainless steel plates have been successfully fitted and secured, and the grout installation has been completed without a hitch.
We anticipate all repairs will be complete late April 2018.

After a relatively short holiday break, the seawall dive team has been back on the job since 3 January.
The dive team has expanded to two, four-man teams meaning progress on the face of the seawall has considerably sped up.
We anticipate all repairs will be complete early April 2018.
