Following Tropical Cyclone Debbie in 2017, the existing revetment at Conway Beach was deemed as severely damaged. A replacement rock seawall was designed by ICM and constructed to protect critical infrastructure, improve coastal resilience, and enhance public access.
Project Details:
Client: Whitsunday Regional Council
Date: 2018 – 2019
Location: Conway Beach, Queensland
About This Project
The Challenge:
Severe storm events, including Tropical Cyclone Debbie, had caused significant damage to the existing revetment at Conway Beach, leaving critical public infrastructure - including Penhallurick Esplanade, the carpark, and foreshore amenities - at risk of further erosion. Without intervention, continued coastal recession could have led to infrastructure failure, loss of public access, and increased maintenance costs. A durable, cost-effective coastal protection solution was required to safeguard the foreshore while enhancing public access and beach amenity.
The Solution:
ICM was engaged to assess, design, and oversee the construction of a replacement rock seawall, ensuring a long-term, resilient coastal protection strategy.
Detailed Design:
A comprehensive site assessment informed the optimal seawall design and construction approach.
The seawall was designed to protect critical infrastructure while reducing wind-blown sand, enhancing public access, and minimising long-term maintenance costs.
Construction Inspection & Certification:
Construction was undertaken by East Coast Civil Contracting between February – June 2019.
ICM provided construction inspection and certification services, ensuring full conformance with design requirements and approval conditions.
Final RPEQ certification was provided upon completion, confirming compliance with engineering and environmental standards.
"We were proud to design a rock wall solution for Whitsunday Regional Council that safeguarded critical infrastructure, remained cost-effective, and provided continued community access to the coastline." - Aaron Salyer, ICM
