Monitoring Auckland’s Historic Ferry Building

Auckland’s Ferry Building is an historic landmark in the New Zealand city. In the 100 years since it was built, the sea wall supporting the structure was gradually eroded by constant sea movement and wash from ferries docking and leaving the port. Divers discovered a large three-metre scour at the base of the sea wall that needed to be repaired and stabilised to ensure the safety and longevity of the building and underlying structure. After closer inspection a number of additional holes in the seawall were discovered. To ensure there was no damage to the building during repair works, Auckland Transport enlisted the services of CKL – a local engineering and surveying firm – to monitor the structure.
