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.
During the most recent mining boom we delivered most of the new iron ore export wharves for FMG, BHP and Rio Tinto. We've also delivered hundreds of kilometres of gas pipelines and rail infrastructure throughout the state.
Closer to the CBD we've delivered rail grade separations, and all the mechanical and electrical packages for Perth's first desalination plant.
The Midland Junction Alliance (MJA), an alliance comprising of ourselves, Georgiou Group, Arcadis and BG&E, is delivering the new METRONET Midland Station in Perth, Western Australia. METRONET is a multi-government agency created to oversee the expansion of Perth's metropolitan transport network.
The Midland Station project includes decommissioning and demolishing the existing 53 year old train station and the design and construction of a new station between Helena and Cale streets.
Delivered as part of the Public Transport Projects Alliance (PTPA), we delivered this small but complex road-over-rail bridge replacement to cater for significant local traffic increases due to the construction of a nearby freeway.
The success of the project was underpinned by our team's ability to implement traffic diversion, construction staging, and rail possession strategies that minimised impacts to road and rail traffic.
As part of an Alliance with our customer, Department for Infrastructure and Transport, CPB Contractors, and designers Mott MacDonald, Arup and Aurecon, we are delivering the Tram Grade Separation Projects in Adelaide, South Australia.
Jointly funded by the Australian and South Australian governments, the projects involve the removal of multiple level crossings along the Glenelg tram line.
We are the constructor and leader of the Western Program Alliance, delivering part of the Victorian state government’s ambitious level crossing removal program, which is set to remove 110 dangerous level crossings by 2030.
Our Alliance brings together ourselves, the Level Crossing Removal Project (government), MTM and V/Line (network operators), and Arup and Mott MacDonald (design partners).
We delivered the first tranche of the Inland Rail project in Victoria - the Beveridge to Albury (B2A) package. The overall Inland Rail project will enable double-stacked freight trains to operate between Brisbane and Melbourne.
Our contract encompassed four 'rail enhancement' sites located in central and northern Victoria, as well as some corridor wide works. The enhancement site works included bridge replacements at Glenrowan, Wangaratta and Seymour; transformation of Wangaratta Station; and track lowering. Corridor wide scope included signalling works, track slews and overhead utilities.
In an alliance with the South Australian State Government, Mott MacDonald and Arup, we successfully removed the level crossing at Torrens Road, Ovingham, improving travel times, bus reliability, and safety and amenity for the community.
Located near the fringe of the Adelaide CBD, an average of 21,300 vehicles passed through the crossing daily before it was removed.
The Oaklands Rail Crossing Grade Separation, located 12.8 km south of Adelaide, was a key initiative of the South Australian Government and part of a program of public transport projects.
The project was designed and constructed by the Public Transport Projects Alliance (PTPA), comprising ourselves, Arup and Mott MacDonald (design) and Department for Infrastructure and Transport (customer).
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.
Working within the heart of Penrith, New South Wales to deliver the Jane Street and Mulgoa Road Upgrade, we developed innovative construction and staging solutions to minimise disruption to the community and commuters.
The biggest technical challenge was the installation of a new rail bridge over a busy road.
The reference design nominated a sequential construction method where the new rail bridge was intended to be constructed beside the existing bridge location and slide into place. Due to issues associated with the relocation of both known and unknown utilities, along with the potential safety and efficiency issues, a decision was made in conjunction with our customer to consider an alternative construction and installation methodology.
We elected to use Self-Propelled Modular Transporters (SPMTs) that allowed the bridge to be picked up and driven into position.
Due to the changed installation method our team worked with our designers to ensure that the bridge would withstand the forces applied to it during installation that hadn’t previously been considered.
We used the international expertise of specialist SPMT provider Sarens to plan and execute the successful movement of the bridge, shown below.
