Our civil design team includes coastal, waterway and flood engineers that undertake concept and detailed designs, numerical modelling, and options appraisals for new structures
We undertake options analysis, concept design and detailed design for councils, government agencies, ports, marinas, and private organisations. These designs are for detailed extreme-weather mitigation structures, aimed at protecting against flooding, coastal erosion, wave overtopping, waterway failures, scour, bank instability, and slip circle failures.
Innovation is at the heart of all we do. We invest strongly in research and development, responding to the needs of clients to provide bespoke innovative solutions and incorporating the latest technical knowledge through collaboration with industry, academia and government
Seawalls built using Geosynthetic Sand Containers (GSC) can be an economical coastal defence against erosion and wave overtopping. However, with increasing sea levels and larger waves the standard 2.5m3 units are not always suitable. We completed the investigation, design, and managed the physical testing of new technologies for these high-risk areas. This considered various shapes, new ways to interlock the bags, but settled on larger bags sizes (up to 8t or 4.5m3) which were tested under extreme conditions in the Water Research Laboratory (WRL), Sydney. Our team completed the redesign of the Maroochy Groynes using the new bags, a first for the Sunshine Coast of Queensland.
Here are just some examples of our work in extreme weather engineering
