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..

Oil & Gas

Oil & Gas

From major processing facilities to marine infrastructure we've have been delivering creative solutions to the international oil and gas industry for more than 50 years.

Our fully-integrated service includes civil works, marine and cross-county pipeline construction, fabrication and structural mechanical piping (SMP) - all supported by our global engineering and procurement capabilities.

Our construction and commissioning schedules are coordinated locally to take advantage of a strong understanding of regional construction capabilities, capacity and performance. This enables us to control safety, quality, scheduling and costs.

Lake Way and Karlawinda Gas Pipelines

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.

Fast Facts

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.

Fast Facts

  • 481 km, 12 inch pipeline
  • Three cathodic protection stations
  • Three mainline valve stattions
  • One midline station (pig trap)

APLNG Pipeline

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.

Fast Facts

  • 360 km, 42" mainline pipeline
  • 57 km, 36" lateral pipeline
  • Launcher station at Condabri
  • Pipeline hub
  • Midline scraper station
  • 4 mainline valve stations

QCLNG Pipelines EPC Curtis Island, Queensland

Narrows Crossing (QCLNG)

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.

Fast Facts

  • 12 km, 42 inch twin pipelines
  • Two 8 inch FOC ducts

Fluor Australia Pty Ltd Construct Only Roma, Queensland

GLNG Upstream - Roma Hub and Pipelines

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.

Safety

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.

Environmental

Environmental

We understand the impact construction can have on our natural ecologies and we're constantly seeking ways to minimise our footprint and restore and improve the natural environment and biodiversity around our 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="MCD Carbon roadmap 2030"} 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.

Social

Social

We consider the 'Social' aspect of ESG to encompass everything related to people.

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.
