Thank you for considering McConnell Dowell. This short capability statement explains a bit more about the benefits of working with us and showcases our capabilities and some of the interesting projects we deliver.
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 do that through delivering projects that connect, sustain and enhance communities, and through providing career opportunities that challenge, reward and grow our people.
We also have five company values that guide our behaviours and decisions. Our values are:
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.
It's the technical problems and challenges solved behind the scenes by people empowered to think creatively and work collaboratively. It’s the alternative idea or innovation that saves time, reduces cost, makes us safer, and delivers more value.
It might not always be evident when you look at the end product, but it's there, inside every McConnell Dowell project.
This helps them identify and address potential issues at the earliest stages of project development, effectively eliminating issues at their genesis leading to lower costs and delays once we start on site.
On site, we use digital tools like drones for surveying, and GPS tracked plant to monitor and improve safety and efficiency.
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.
Following a destructive tropical cyclone, we were engaged by South32 to urgently restore and rebuild the cyclone-damaged GEMCO Wharf on Groote Eylandt. In less than 12 months, our project team achieved a major milestone—restarting operations after an intense and fast-tracked program of works.
To meet the challenge, we mobilised a sophisticated marine fleet from across Australia, Singapore, and the UAE. This included two large jack-up barges (Santa Fe and Pauline), two smaller jack-ups (Sealift 2 and Sealift 6), a 250-tonne crane barge, three flattop storage barges, and a support fleet of tugs and work punts. The mobilisation alone was a feat of logistics, setting the stage for a highly coordinated recovery effort.
We completed the main berth construction scope for BHP Mitsubishi Alliance's (BMA) SABR Project, using the Early Contractor Involvement process to develop a number of innovations.
SABR, short for 'Shiploader and Berth 2 Replacement', was a brownfields project located within the lease boundaries of BMA's existing Hay Point Coal Terminal near Mackay, Queensland. It included the disassembly and replacement of one of the existing shiploaders and berths to improve materials handling throughput and cyclonic wave immunity.
We received the Australian construction industry's highest accolade for this major wharf redevelopment within Melbourne's main port precinct.
This was a large and complex marine project delivered within Australia's busiest operational container port, and within very tight environmental controls to protect the rich marine life within the surrounding bay.
Drawing on our unmatched experience in the Port of Melbourne, we were engaged by Toll Transport to upgrade their wharfs and berthing infrastructure at Webb Dock, Melbourne and McGaw Wharf, Burnie. These terminals service Toll's trans-Bass Strait shipping route.
Upgrades were required at both facilities in advance of Toll receiving two new larger vessels which were longer, wider, deeper and heavier, resulting in the need for significant modifications to the existing infrastructure.
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.
Working for the Port Authority of New South Wales we delivered a series of improvements to the Overseas Passenger Terminal (OPT), located in the iconic Circular Quay area of Sydney Harbour.
Built in 1960, the OPT is located in one of Australia’s busiest waterways. Over time, natural processes and vessel activity have caused scouring, accretion and movement of materials on the seabed around the terminal’s wharf.
We refined the initial concept design and constructed a new outer wharf structure at HMAS Coonawarra in Darwin to support the Australian Defence Force (ADF). The project involved the construction of a new 250 m long wharf and two approach jetties.
While the final structures are simple in their geometry and configuration, the site location and operational requirements were challenging.
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.
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.
Using an innovative, flood-resilient design, we upgraded upgrade seven ferry terminals along the Brisbane River for Brisbane City Council. These replaced the orginal terminals lost or damaged in serious flooding. We also built a new terminal at Milton to service residents and workers.
The new facilities, capable of berthing two CityCat vessels simultaneously, include new covered waiting areas and access gangways, steel pontoons, and a debris deflection system.
We successfully delivered two new wharves at La Perouse and Kurnell on Botany Bay (Kamay) for the NSW Government. These modern structures replace the original wharves, which had been in operation from the 1890s until 1974, when severe storms rendered them beyond repair.
The Kurnell site holds deep historical and cultural significance. As the first landing place of Captain James Cook, it is a key part of Australia’s colonial history. Equally important, the area remains a place of enduring cultural heritage for First Nations people. To honor this, the wharf designs incorporate large-scale artworks by local Aboriginal artists, creating a meaningful connection to Country.
At the height of the Australian resources boom (2004-2014), we became the marine partner of choice for Fortescue Metals Group (FMG), as they developed the infrastructure to support their new iron ore export business.
Working closely with the Cook Islands Port Authority, we expanded their existing port facilities to accommodate larger cargo and cruise ships. Staging our works around their existing operations, we implemented a number of initiatives to expedite the works.
Our scope included: construction of a new 270 m long wharf; dredging and widening of the main harbour to increase turning movements for ships; armoured revetment shore protection around the entire harbour; demolition of wharf structures and buildings; and provision for new lighting.
Improving marine infrastructure for nine Pacific Island countries as part of the Australian Government’s Pacific Maritime Security Programme (PMSP) fits perfectly with our vision: Providing a Better Life.
This project also demonstrated our ability to deliver logistically challenging marine projects across the Pacific.
We upgraded the Queen Sālote International Wharf in Nukau'alofa for the Tongan Ministry of Infrastructure between 2023 and 2025, on time and on budget, with zero LITs during the one million hours worked.
The wharf is Tonga’s only international port, a lifeline for the country, processing 95% of the country's imports and exports. This critical infrastructure upgrade modernised and climate-proofed the facility, increased capacity, and improved power, drainage and water services.
When Port Kembla Port Corporation needed to replace one of NSW's oldest jetties, we brought their vision to fruition and turned what was a liability into a world-class asset.
We constructed a new 270 m long breakwater jetty using 90,000 m3 of imported rockfill and 20,000 m3 of rock armour. Prior to commencing the works, approximately 30,000 m3 of sandy clay, stiff clay and loose rock was dredged from the harbour floor using a Cutter Suction Dredge (CSD) and pumped one km into the outer harbour.
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.
As part of the $10 billion Roy Hill Iron Ore project, we designed and constructed the Stanley Point Iron Ore Terminal at Port Hedland. We used substantial prefabrication and our innovative temporary works system for low impact, high productivity construction.
Our scope consisted of a two berth iron ore load out wharf, connected with a 3600 m long elevated road and overland conveyor to the ore stockyard. In addition to the wharf and the overland conveyor, we delivered an abutment, drive stations, three transfer stations and all SMPE&I works.
We've embraced the circular economy, renewed local ecologies, reconnected habitats, and lowered energy use across our projects in line with our {tip title="Carbon Reduction Roadmap" content="
"} carbon reduction road-map {/tip}.
We set energy and waste reduction targets on every project and are committed to making our environmental footprint as small as possible, as showcased in the recent case studies below.
That's from ensuring everyone goes Home Without Harm, to making a positive and meaningful impact on the well-being and prosperity of our employees, stakeholders, and the communities we engage with. This focus aligns seamlessly with our purpose of 'Providing a Better Life'.
Our commitment begins with our rigorous safety management system and extends to maximising local employment and supply opportunities, as well as delivering needs-based community support and uplift initiatives through our projects.
We foster our 'Home Without Harm' safety culture through robust processes, effective systems, and by recognising and rewarding safe behaviours.
Our Site Safety Managers are always on our project leadership teams, ensuring safety is prioritised in all site activities. Every team member has clear safety responsibilities, aimed at protecting themselves, their colleagues, and the community.
We're also leading our industry in the adoption of new safety technologies, like virtual reality plant simulators and AI-enabled blind spot elimination. Check out the case studies below for more information.
Underpinning it all are our Safety Golden Rules. Built on our long-term collective knowledge and learnings, they are specifically targeted at preventing fatalities and serious injuries.

Our approach is clearly articulated in our Sustainability Policy.
We're about action not just aspiration. Our ambitious but achievable {tip title="Carbon Reduction Roadmap" content="
"} carbon reduction road-map {/tip} will see us be operationally net zero by 2030, with 44 initiatives that are being progressively rolled out across the company. Last year we reduced our carbon emissions by 442 tonnes through the use of solar technologies alone, and diverted almost two million tonnes of waste from landfill.
