Prepared for Pipelines & Airports
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..
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.
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.
FGEN LNG Corporation (FGEN) engaged us to build and deliver the Interim Offshore Terminal Project ("IOT Project") at their LNG terminal in Batangas, in the Philippines.
We undertook the engineering, procurement and construction of both the Multi-Purpose Jetty and Onshore Gas Receiving Facility. The new Multiple Purpose Jetty is a permanent modification of the existing liquid fuel jetty which we constructed in 1998.
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.
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.
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.
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 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 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.
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.
Our ability to solve technical challenges creatively, means we find ways of delivering complex civil structures with minimal disruption to the community and our customers' operations.
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:
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:
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.
