Prepared for Marine Construction
May 2026
From remote resources and energy projects to city-shaping infrastructure, we've built thousands of quality assets and facilities.
Engineering-led, our expertise has grown steadily to span building, civil, electrical, fabrication, marine, mechanical, pipelines, rail, tunnel and underground construction..
We also understand that construction today is as much about community and sustainability as it is about concrete and steel. Our unwavering objective and commitment is to deliver what we promise to our customers, while protecting and enhancing our people, the community and the environment.
Our services encompass the complete project lifecycle—from early concept design to commissioning and ongoing maintenance. We tailor each solution to suit our customer's specific project objectives and preferred delivery approach.
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 revolutionised the design and construction of large-scale marine infrastructure when we delivered the Chith Export Facility - a large, complex and remotely located project for Rio Tinto at their Amrun bauxite mine, south of Weipa in Far North Queensland.
The facility comprises a 650 m access jetty, a 350 m loading wharf and an onshore conveyor system. Innovatively designed by Jacobs and constructed by us in just 10 months, modularisation was at the heart of the solution and our project team took it to new levels in scale and breadth.
In one of the first Early Contractor Involvement (ECI) contracts in Australia, we designed and delivered the Techport Australia Common User Facility - a new state-of-the-art shipbuilding and maintenance complex on the Port River at Osborne, South Australia. We delivered it in joint venture with our building company, Built Environs (the MDBE JV).
The project was rolled out in two stages. In the first stage, our team worked in collaboration with design and technology partners and DefenceSA to develop the final design and risk adjusted price.
We designed and constructed the marine structures for BCI Minerals’ Mardie Salt & Potash Project in Western Australia, using our innovative canti-traveller system for speed and low impact delivery.
The 'Mardie' Project is a large-scale, solar evaporation operation on the Pilbara coast. Capacity of the completed facility is estimated to be 5.35 million tonnes per annum of high purity salt and 140,000 tonnes per annum of sulphate of potash, over an operating life of at least 60 years.
After a 6-month Early Contractor Involvement process, we're now delivering a berth extension and remediation works at the Flinders Adelaide Container Terminal (FACT) — South Australia’s only container terminal.
Our works form part of Flinders Port Holdings’ (FPH) A$350 million GatewaySA Program, a multi-year initiative designed to increase capacity, efficiency and sustainability across the terminal.
We recently completed Stage 1 of the Swanson Dock West Remediation, and are now delivering Stage 2. This is our sixth project for Port of Melbourne since 2017.
Swanson Dock West (SDW) is a critical International Container Terminal comprising of a 944 m wharf with three container-handling berths, which were constructed in several stages between the 1960s and 1980s. The existing wharf is of varying forms of construction and some sections are close to or beyond the typical design life of 30 years. As a result, major remediation was needed.
Working in collaboration with the Port of Melbourne, we successfully completed four contracts at Swanson Dock between 2017 and 2020.
After completing the award winning Port Capacity Project, we continued our partnership with Port of Melbourne with a series of smaller contracts to rehabilitate the iconic Swanson Dock - the heart of Australia's busiest container terminal.
Engaged by Squadron Energy, one of Australia’s leading renewable energy companies, we helped establish a new gas import facility at Port Kembla to bring flexible additional energy supply to the eastern seaboard of Australia.
The facility, built on an abandoned coal export terminal, has the capacity to supply more than 70% of NSW’s gas needs.
The McConnell Dowell Decmil Joint Venture delivered the Mordialloc Freeway in Melbourne’s south east four weeks ahead of schedule while setting new industry benchmarks in sustainability and workplace mental health management.
The nine kilometre freeway links the Mornington Peninsula Freeway at Springvale Road in Aspendale Gardens to the Dingley Bypass in Dingley Village, creating a continuous freeway from Frankston To Clayton.
