Location

Lucinda

Completed

2024

Civil IQ developed the detailed design for the replacement of eight ageing groyne structures along the Lucinda foreshore, delivering a practical long-term coastal protection solution supported by planning approvals, stakeholder engagement and detailed engineering assessment.

Project Overview

Eight existing groyne structures constructed from geotextile sand containers had reached the end of their design life and required replacement to maintain shoreline protection along the Lucinda foreshore.

Civil IQ worked with Hinchinbrook Shire Council to develop a replacement solution, undertaking planning approvals, multi-criteria assessment, coastal engineering design and stakeholder engagement to identify the preferred option and progress the project through detailed design.

Challenges
