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.
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.
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.
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.
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.
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.
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.
We joint ventured with ITP (IMJV) to design and construct the VTB (Vacuum Tower Bottoms) Subsea Pipeline for ExxonMobil in Jurong Island, Singapore.
Vacuum Tower Bottoms are the left over bottom product of distillation, which can be processed in cokers and used for upgrading into gasoline, diesel and gas oil.
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 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.
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.
