Jackson Bay Causeway Upgrade

Saving a community asset

PROJECT: Jackson Bay Causeway Upgrade CONTRACTOR: Liddell Contracting, part of the Isaac Group CLIENT: Westland District Council VALUE: $1.2m

In 2020 Westland District Council (WDC) approached Liddell Contracting to scope and repair the Jackson Bay wharf, which is critical infrastructure to the Jackson Bay and Haast community.

This was therefore a very important community project – if work could not be completed within WDC’s budget, there was a real risk the wharf could no longer be used. Despite the complexities of delivering works in a very remote location, which was hard to access, experienced weather extremes and subject to tidal conditions, the Liddell team found a way to repair the wharf’s causeway within WDC’s budget. We applied engineering skill, and out of the box thinking to value engineer a cost-efficient repair solution. This included developing three ‘bespoke’ items of plant with which to access the structure and manoeuvre timbers CONSTRUCTION EXCELLENCE AWARDS 2022 CCNZ / HIREPOOL and components. As a result, the community of Jackson Bay has a wharf structure which is safe and can continue to be used. Stage Two to refurbish the main wharf has also been future-proofed – the access methodology and gear developed for the causeway portion will enable these works to be performed in a similarly safe and cost-efficient way.1 33
