We are specialists in all facets of coastal protection and flood resilience.
This includes construction of revetments, seawalls and other coastal protection barriers, building and operating largescale sand management systems. We also construct every type of flood retention and stormwater management system, including high capacity pump stations and large diameter water pipelines and outfalls.
Here's some recent examples.

From major processing facilities to marine infrastructure we've have been delivering creative solutions to the international oil and gas industry for more than 50 years.
Our fully-integrated service includes civil works, marine and cross-county pipeline construction, fabrication and structural mechanical piping (SMP) - all supported by our global engineering and procurement capabilities.
Our construction and commissioning schedules are coordinated locally to take advantage of a strong understanding of regional construction capabilities, capacity and performance. This enables us to control safety, quality, scheduling and costs.
Construction is optimised through modularisation, maximising offsite fabrication and minimising site construction risks and durations.
We understand what matters most to our water industry customers - uninterrupted supply, minimal disruption, safety, compliance, and positive community engagement.
We've been entrusted with the design and delivery of major metro desalination and water treatment plants, as well as the construction of dams and large-diameter pipeline and pump station networks.
We've delivered approximately $9 billion in new water assets over the last 15 years, including:
Kilometres of water pipeline
High-capacity pump stations
Large capacity water tanks & dams
Advanced water treatment plants
We prioritise zero-impact solutions, like trenchless pipelaying, ensuring that our projects are executed with minimal disturbance to landowners, traffic, and the environment - reducing noise, dust, and disruption.
Our long-term partnerships with water authorities go beyond construction - we operate, maintain, and upgrade advanced wastewater treatment plants, guaranteeing facilities that meet strict supply, performance and safety requirements.
When you work with us, you’re choosing an experienced water contractor committed to continuity, safety, quality, and environmental responsibility.
