With over 330 marine projects completed across six decades, McConnell Dowell is synonymous with marine infrastructure.
From wharves and jetties to ocean outfalls, breakwaters, and submarine pipelines — we bring coastal confidence to every project.
Our modular approach to construction has helped create productive ports for clients like Rio Tinto, FMG, Vale, and BHP, where over 1.2 billion tonnes of iron ore are shipped annually from wharves we built.
We thrive in complex, operational environments — delivering innovative temporary works and safe, efficient methods that protect people, environment, and productivity. From purpose-built barges to proven marine systems, we engineer safe harbours with precision and care.
At McConnell Dowell, we don’t just build marine infrastructure — we deliver it with certainty, creativity, and a commitment to results.
