Prepared for Prepared for Sydney Airport
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.
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:
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.
Urban projects have included construction of two new recreational wharves at Kamay (Botany Bay); the design and installation of complex subsea pipelines for the Sydney Desalination Plant; the transformation of Penrith's CBD through the Mulgoa Road upgrade; and the refurbushment of the Overseas Passenger Terminal in the iconic Circular Quay.
Regionally, the company has constructed a new LNG gas import terminal and a tug boat facility at Port Kembla in Wollongong; upgraded the Hume Dam in Albury; duplicated the Pacific Highway between Kempsey and Kundabung; and supported ARTC with track upgrades in the Hunter Valley.
We've been working with the Auckland International Airport team since January 2019 to maintain and improve critical assets, including upgrading live jet fuel pipelines, renewing runway pavements, and much more.
We have also worked on vertical construction projects, including the new airport upgrade with subsidiary Built Environs.
McConnell Dowell Ltd (MCD) won stages two and three of the Auckland Airport’s Terminal Development Project (TDP) in late 2019. The aim of the work was to enable future expansion of the fuel stands, runway and airport terminal. The McConnell Dowell proposal outlined a programme that would enable the team to deliver better safety outcomes, reduce costs and maintain high quality.
The project was completed in two stages:
The Dryandra Road Works contract was a significant component of the New Parallel Runway (NPR) project for Brisbane Airport Corporation (BAC).
The Project involved construction of a 1.5 km long, four-lane reinforced concrete underpass structure, supported on approximately 700 precast concrete piles. The underpass allows vehicular access either side of the new linking taxiways, which were constructed as part of the NPR project.
We resurfaced the runway at Pago Pago Airport to improve its condition rating, and raise the shoulder edge by four inches to meet FAA requirements for international airports. Our work included a complete survey of the existing site; construction of Runway 5-23, the shoulder pavement, two taxiway and turning node pavements and paint-marking.
This was our eighth airport project in the Pacific Islands and followed our successful completion of the USD6.7 million rehabilitation and extension of Runway 8-26 in 2007 and the Taxiway Alpha Rehabilitation in 2011.
Our American Samoa team completed the contract to resurface and rehabilitate the asphalt pavement on the primary runway at Pago Pago International Airport in mid-2025.
This is the ninth project we've completed for the Pago Pago International Airport. Other recent projects for the Airport included upgrading 915 m (3,000 feet) of the runway, for Stage One of Runway 5-23 completed in 2018, and the Apron Rehabilitation Project finished in 2020.
The Papa, Uniform, Golf Taxilane Slab Replacement project involved the replaced and restoration of ageing concrete pavement at Melbourne International Airport. The project was part of Melbourne Airport’s airfield pavement maintenance program, improving and maintaining the safety of the airport.
Our scope of work involved:
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.
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.
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.

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.
Thank you for taking an interest in McConnell Dowell's skills, capabilities and approach. Additional information is available on our website, including additional project case studies.
