Introduction General
Thank you for the opportunity to present this brief capability statement which details a cross-section of our skills and experience, and showcases a selection of our recent projects.
About Us (typically use first)
For over 65 years customers have been coming to McConnell Dowell with complex projects that require innovative solutions. That's why we're known as the Creative Construction company.
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..
Our History (use sparingly)
In 1961, two ambitious young engineers from New Zealand—Malcolm McConnell and Jim Dowell—set out with a bold vision: to build a company that would do things better than the one they worked for. That vision marked the birth of McConnell Dowell.
Since then, innovation and creative construction have remained at the heart of everything we do.
Here's our 65 year history through the decades...
Purpose & Values (typically use 2nd or 3rd)
We are a Purpose and Values driven organisation. These define what's important to us, guide our decision making and unite us behind a common goal.
Our Purpose is Providing a Better Life.
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:
Safety
We never compromise on safety.
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.
Sustainability (ESG)
Our purpose is 'Providing a Better Life’ - today and into the future. That’s why sustainability, in all its forms, is considered in every project, process and product across our business.
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.

Northern Gas Pipeline
Constructing a 481 km transmission pipeline providing gas reserves to industries in Mt Isa
Engaged by Jemena under an exclusive ECI agreement, we designed and constructed the remote Northern Gas Pipeline, opening up the Northern Territory's gas reserves to industries in Mt Isa, Queensland.
Our scope involved the design and construction of approximately 481 km of 12-inch diameter high pressure gas transmission pipeline and associated pipeline facilities including two mainline valves and a midline scraper station. The pipeline transports gas from existing offshore and onshore gas reserves in the Northern Territory and will supply this gas to Incitec Pivot’s Phosphate Hill plant located south of Mt Isa and other users.

Creative Construction
Creative Construction at McConnell Dowell is the inspired engineering behind the complex infrastructure we deliver.
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.
Using 4D planning to streamline project delivery
On a recent rail duplication project in Melbourne, our team used digital engineering and 4D modelling to streamline the design and "rehearse" the construction of a 340 tonne steel bridge being launched over a waterway.
The 4D planning exercise was a game changer in helping the design, engineering and construction teams achieve an authentic digital rehearsal. The process helped identify and rectify early problems, including a clash between temporary and permanent retaining walls, as well as signalling cables and wall panels.
After months of painstaking planning and the ‘virtual launch’, the 63 metre long, 340 tonne steel bridge structure was successfully moved into position during the rail occupation.
The project team received an innovation award for the work done on this project.
Our Approach (typically use 2nd or 3rd)
We approach every project with a focus on creativity and certainty - seeking the right blend of innovation and safe, proven approaches so we can exceed our customers' expectations.
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.
