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're experienced working in all types of conditions and locations, on land or off shore, from the heat of the Australian desert to the tropical rainforests of Indonesia. No matter how difficult or remote the site, it’s our creative solutions that our resources customers value.
Our construction capability covers every aspect of the resources supply chain - from pit or well to port.
Recent projects that reflect our capabilities in sustainable power generation include the engineering, procurement and construction of the 166 MW Te Mihi Geothermal Power Station in New Zealand; the refurbishment of the 75 MW Ambuklao and 100 MW Binga Hydropower Plants in the Philippines; and the current Kidston Pumped Storage Hydro Project in Queensland.
McConnell Dowell is a leading international pipeline contractor. We have constructed over 20,000 km of new pipe networks across more than 200 projects including gas, petroleum, water and slurry pipelines. These pipelines help drive economic and social progress across Australia, New Zealand, and South East Asia.
We are experts in large diameter pipeline construction and have delivered gas pipelines up to 1300 mm (50”) in diameter and water pipelines up to 1800 mm (70”) in diameter. Our in-house specialist skills and plant enable execution of HDD, micro-tunnelling, marine pipe pulls, pipe bridges and other complex crossing solutions.
We constructed a 145 TJ per day gas compression and water treatment hub, with associated infrastructure and water gathering lines, at the coal seam gas fields north east of Roma in Queensland. The infrastructure enabled collection and processing of gas for delivery via an export pipeline to an LNG processing plant on Curtis Island, off Gladstone.
The large and complex project required a multi-disciplinary approach, with a focus on facilities for gas compression, power generation and water treatment, in addition to pipeline construction.
Following successful completion of an Early Works contract for the APLNG project, MCJV, a joint venture between ourselves and Consolidated Contracting Company Australia Pty Ltd, was awarded an EPC contract for delivery of 360 km of the main export pipeline, a 57 km lateral pipeline, and associated facilties.
The overall APLNG project included the development of substantial coal seam gas resources in the Surat and Bowen Basins. The key elements of the project were the transmission pipeline, subsea crossing (Narrows Crossing) and a multi-train LNG facility on Curtis Island, near Gladstone.
In joint venture with Consolidated Contracting Company (the MCJV), we designed and delivered the Narrows Crossing project, one of the most diverse and challenging pipeline projects ever completed in Australia.
Our scope involved the connection of the QCLNG and APLNG 42” export pipelines from their termination points across the Narrows Channel to the LNG plant on Curtis Island. We also delivered the QCLNG Delivery Station.
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.
After extensive pre-planning and a fast mobilisation, we constructed the Agnew Gas Pipeline Project for APA Group in the south-southwest of Western Australia. The new pipeline supplies gas to the Agnew gold mine site to supplement the mine’s renewables-fuelled power supply.
Our scope consisted of the construction of a 25 km long, DN150 mm, dual layer FBE coated, AS2885 compliant, high pressure natural gas pipeline, along with the tie-ins to the swan necks at the above ground Kyarra Offtake Station and the Agnew Delivery Station.
We constructed the Lake Way Gas Pipeline (LWP) and the Karlawinda Gas Pipeline (KGP) projects for APA Group in Western Australia.
The LWP pipeline is located 15 kilometres south of Wiluna and transports natural gas from APA’s Goldfields Gas Pipeline (GGP) to SO4’s Lake Way facility. SO4 aims to become a major exporter of Sulphate of Potash and the LWP pipeline provides gas for fuelling power generating facilities and other equipment within their process plant.
We constructed the Murrin Murrin Looping Project for APA Group, east of Lenora in Western Australia. The objective of the project was to increase the capacity of the Murrin Murrin Lateral to enable APA to service future downstream customers.
Our scope consisted of the construction of a 13.8 km long, 200 mm diameter high pressure gas pipeline, along with the tie-ins to an existing above-ground offtake station. The pipeline runs from a connection off the existing Murrin Murrin Lateral.
The FTP2 Project was awarded to our Thailand team and involved approximately 70 km of 42" high-pressure gas pipeline constructed between Rayong LNG Terminal in the south to the Wang Noi – Kaeng Khoi Pipeline Tie-in Station in the north.
Work was spread over 300 km and involved more than 20 km of trenchless pipe installation and construction of significant above-ground facilities. The peak site workforce exceeded 2,800 across 50 discrete work locations.
We've delivered structural, mechanical and piping projects in live operating environments for multi-national customers such as ExxonMobil, BP, BHP, Rio Tinto, FMG, DuPont, and various water authorities.
Our project engineers and construction leaders have specialist skills in mechanical and electrical design and installation, and we have successfully managed projects with peak workforces in excess of 1000 people.
We optimise construction outcomes through the use of modularisation, prefabrication and preassembly - minimising site risks, durations and impacts, and ensuring cost savings and high quality outcomes for our customers.
We continue to achieve industry-leading results in safety performance and customer satisfaction.
We are constructing the Kidston Pumped Storage Hydro Project in Far North Queensland - an innovative project that involves the world-first conversion of a disused gold mine into a pumped storage hydroelectric power generation facility.
This first-of-its-kind natural battery storage facility has the potential to generate up to 250 MW of rapid response (less than 30 seconds), flexible power to Australia’s National Electricity Market.
Awarded the design and construct contract for the Bogong Power Development Project by AGL, our engineers set about developing smart design and construction strategies that ultimately reduced the project cost by A$30 million.
Consisting of a network of tunnels and shafts and the construction of a new underground hydro electric power station, the Bogong Power Development Project is the largest hydro power project constructed in Australia in 25 years.
In joint venture with Diona (the Water North JV) we're one of three major framework partners delivering SA Water’s multi-billion dollar capital delivery program. The 'Frameworks' model fosters collaboration and innovation in the planning and delivery of water projects across metro and regional South Australia.
During the first four years (2020 - 24) our team delivered approximately 150 projects, including the design and construction of:
We devised, designed, constructed and operated the unique Tweed River Entrance Sand Bypassing system, building it in the late 1990s and operating it for 25 years. The facility ensures a safe and navigable entrance to the Tweed River, and maintains the ecology and amenity of beaches on the southern Gold Coast.
The centrepiece of the facility is the sand collection jetty which is approximately 450 m long and extends approx 300 m from the shoreline. A sand trap or depression is formed under the jetty by the operation of 10 submerged jet pumps approximately 10 m below the seabed. Natural wave action feeds sand into this trap. Up to five jet pumps are then used to create a sand-water flume which flows under gravity to the control area.
We developed some innovative design and construction solutions to upgrade 1950s-built Cosseys Dam, after Watercare detected significant deterioration. Located in the environmentally sensitive Hunua Ranges, the earth fill structure is Auckland's third largest dam and holds 14% of the city’s water storage.
The earthfill dam stands 49 m high and 170 m long at the crest. It has a 230 m long diversion tunnel linking to a valve tower and scour systems.
We were a member of the Adelaide Aqua consortia responsible for designing, building, and commissioning the Adelaide Desalination Plant, the state's largest ever infrastructure project. The reverse osmosis plant is one of the most efficient in the world and can produce 100 GL of fresh water each year.
The project encompassed all construction disciplines including bulk earthworks, civil structures, marine, tunnelling, mechanical, electrical, and building works. Some 10,000 people were employed during construction.
We designed, constructed, commissioned and now operate the Adelaide Living Beaches Sand Transfer Infrastructure project in South Australia. Through this network of pipes and pumps we're moving 150,000 cubic metres of sand each year, mantaining the health and amenity of Adelaide's inner beaches.
Sea conditions along Adelaide’s metropolitan coastline results in longshore drift of sand from south to north, stripping the southern beaches of sand when not replenished.
As the principal contractor within the Southern Regional Water Pipeline Alliance, we designed and delivered a new 200-megalitre-per-day water grid on a fast-track program to support the rapidly growing population of South East Queensland.
The project was delivered during the worst drought on record, with Brisbane's water storages at less than 15 percent capacity. This 'need for speed' necessitated concurrent progress in land access, design, approvals, and procurement.
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.
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'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.
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.
