We upgraded the Queen Sālote International Wharf in Nukau'alofa for the Tongan Ministry of Infrastructure between 2023 and 2025, on time and on budget, with zero LITs during the one million hours worked.

The wharf is Tonga’s only international port, a lifeline for the country, processing 95% of the country's imports and exports. This critical infrastructure upgrade modernised and climate-proofed the facility, increased capacity, and improved power, drainage and water services.

Working closely with the Cook Islands Port Authority, we expanded their existing port facilities to accommodate larger cargo and cruise ships. Staging our works around their existing operations, we implemented a number of initiatives to expedite the works.

Our scope included: construction of a new 270 m long wharf; dredging and widening of the main harbour to increase turning movements for ships; armoured revetment shore protection around the entire harbour; demolition of wharf structures and buildings; and provision for new lighting.

Improving marine infrastructure for nine Pacific Island countries as part of the Australian Government’s Pacific Maritime Security Programme (PMSP) fits perfectly with our vision: Providing a Better Life.

This project also demonstrated our ability to deliver logistically challenging marine projects across the Pacific.

We partnered with the Department for Infrastructure and Transport (DIT) to design and construct the new Granite Island Causeway Project. The awarding of the contract followed a collaborative design development process involving DIT, ourselves and our design consultant, WGA.

The Granite Island Causeway, located 83 kilometres south of Adelaide in Victor Harbor is a tourism, commercial and recreational landmark. It is the only link between Granite Island and Victor Harbor and is used by pedestrians, the iconic horse drawn tram service, a small number of vehicles that service the island, tourism attractions and the fishing industry. It is estimated that the number of pedestrians accessing the Causeway is approximately 700,000 per annum.

We successfully delivered two new wharves at La Perouse and Kurnell on Botany Bay (Kamay) for the NSW Government. These modern structures replace the original wharves, which had been in operation from the 1890s until 1974, when severe storms rendered them beyond repair.

The Kurnell site holds deep historical and cultural significance. As the first landing place of Captain James Cook, it is a key part of Australia’s colonial history. Equally important, the area remains a place of enduring cultural heritage for First Nations people. To honor this, the wharf designs incorporate large-scale artworks by local Aboriginal artists, creating a meaningful connection to Country.

Working across 10 different work sites, from private land to remote mountain terrain, we delivered a multi-staged upgrade of the water supply network on Rarotonga. Engaging a significant number of locals on the project, we've left a legacy of new skills and world-class water infrastruture for the Cook Islands.

As the largest infrastructure project ever undertaken in the Cook Islands, Te Mato Vai (meaning 'source of water') delivers fresh drinking water to all residential and commercial properties connected to the existing network. The project was an integral part of the Cook Islands National Sustainable Development Plan.

Co-financed by the Australian and Indonesian governments, we successfully delivered the Palembang Waste Water Treatment Plant Project to improve the health, quality of life, and the natural environment for 40,000 residents on the island of Sumatra.

The project represented a significant undertaking and the centrepiece of a wider program to improve Indonesia's overall sustainability and resilience of essential water assets.

Our in-house mechanical team delivering these works has extensive experience in asset renewal, planned maintenance, and fabrication. They are using advanced techniques such as LiDAR scanning, 3D modeling, and the creation of digital shop drawings to reduce site work and save time compared with traditional methods.

Regularly recording site conditions using drone-captured photogrammetry data has also enabled better tracking and more accurate progress payment claims.

We used our industry-leading marine capability in the design, construction and commissioning of this new raw water pump station for the Thai Oil Company. The new pump station was part of their New Bang Phra Raw Water Line project in Thailand.

The new pump station provides over 4,000 m³/h of raw water and replaced an existing system, which was insufficient due to its low capacity pumps, pipe leakage and corrosion.

We're delivering the Fitzroy to Gladstone Pipeline (FGP) project for the Gladstone Area Water Board (GAWB) and the Queensland Government. The project, which will have the capacity to transport 30 gigalitres per annum, will enable long-term water security for urban and industrial customers in the region.

The FGP, which comprises an approximately 117 km long, 1 m diameter pipeline, a water treatment plant, reservoirs, and pumping stations, will also support the emerging hydrogen industry in the Gladstone region of Queensland. We have teamed up with BMD Constructions in a joint venture (the MBJV) to deliver the Project.

On behalf of Unitywater, we're delivering critical new water and wastewater infrastructure to support growth on Queensland's Sunshine Coast. The new pipelines, pump stations, and storage reservoirs will support the new Aura and Harmony communities in the Caloundra region.

For the Aura development (which will grow to 50,000 residents by 2050), we're delivering a new wastewater network that includes over 12 km of 900 mm diameter pipeline and one pump station. We're also delivering a new water supply network for this community, that includes over 12 km of 800 mm diameter pipeline connecting the Ewen Maddock Dam to a new 12 ML water reservoir.

We delivered the New Bridgewater Bridge project in Hobart - Tasmania's largest ever transport infrastructure project and one of the longest road bridges over water in Australia. The Tasmanian Department of State Growth awarded us the contract based on our innovative design and focus on local industry participation.

The new 1.28 kilometre long bridge replaces the existing lift-span bridge built in the 1940s, providing a new modern crossing of the River Derwent. The new bridge will cut travel times for the 22,000 people that use the route each day. It will also improve freight movement around the state capital.

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.

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.

This project comprised two separate sub-contracts and involved civil and building works for this solar power project. Works were undertaken in eight remote locations in the Cook Islands, and in four locations in Tuvalu.

Our scope of works included construction of power station buildings, complete with a marine grade aluminium roof cladding for the extreme local weather conditions, and solar panel array foundations.

We are fast-tracking the mobilisation of our team, plant, and resources to the site so that they can start work in the coming months.

The project is being jointly funded by the governments of New Zealand and Tonga under the broader Hunga Tonga–Hunga Ha‘apai Response and Recovery initiative. It aims to rebuild critical infrastructure following the 2022 volcanic eruption and tsunami.

An innovative bridge solution saw us secure the design and delivery of this important new river crossing for the Victorian and NSW state governments.

Completed four months ahead of schedule, construction of this vital second crossing between Echuca and Moama included new bridges over the Murray and Campaspe rivers, and two new flood relief bridges.

Appointed as the Managing Contractor by the Department for Infrastructure and Transport, we delivered a major refit and upgrade of the Heysen Tunnels in South Australia, while managing over 45,000 vehicles per day. The result is improved safety, traffic management and incident response capabilities.

The twin tunnels, which are each around 500 m long, are part of the South Eastern Freeway, providing the most direct connection between Adelaide and Melbourne. It is also a key corridor connecting Adelaide and the Adelaide Hills. As part of the National Land Transport Network, maintaining efficient operation of the Freeway is recognised by Infrastructure Australia as a nationally significant issue.

We're delivering three new elevated stations and 2.3 km of segmental precast twin track viaducts as part of the new Jurong Region Line MRT development. The stations are at Tengah Plantation, Tengah Park and Bukit Batok West.

The viaduct comprises of post-tensioned precast segments that will be erected using a combination of launching girders and lifting frames. The project includes a stretch of viaduct erected within metres of multistorey residential towers and a long span crossing of Bukit Batok Road.

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.

Statkraft Norfund Power Investment Group and Aboitiz Power (SNAP) awarded us the Maris South Canal Hydro Electric Power (HEPP) project - an 8.5 MW low head hydroelectric power station in North Luzon, Philippines.

The award built on our 10 year working relationship with SNAP, who are the owners of the Ambuklao Hydro Power Plant in the Philippines, which we rehabilitated for them.

Soon after launching in New Zealand in 2018, McConnell Dowell's building company, Built Environs, successfully tendered and delivered the Auckland City Mission (ACM) HomeGround Development. For the ACM, it represents the biggest project yet in their 100+ year history of helping Auckland’s homeless and most vulnerable.

The new multi-storey facility includes 80 supportive housing units and wrap-around services including a medical centre, detoxification centre, education and training facilities, emergency support and meal services, budgeting advice and other support networks. Built Environs' scope of work also included demolition of three existing buildings and refurbishment of the heritage-listed Prince of Wales building.

The Oval Hotel is a 138-room boutique hotel designed to integrate seamlessly into the existing iconic Adelaide Oval. It is the first hotel in Australia to be integrated into a stadium.

The hotel comprises 90 standard rooms, 39 premium rooms, 7 accessible rooms, and 2 king suites across five stories. The reception pod spans between the north and south wings and is located above the stadiums East Gate. The hotel offers panoramic views of St Peter's Cathedral, Elder Park, River Torrens, the Adelaide skyline and the Mount Lofty Ranges.

Auckland City Hospital is a complex stakeholder environment with patients, staff, specialist service providers, emergency vehicles and a helicopter pad all intersecting within a small footprint in central Tāmaki Makaurau, Auckland.

The project team planned the construction method to suit the 24/7 live hospital environment and minimise disruption to stakeholders by creating a custom traffic management plan, including an access ramp so large vehicles like trucks could be separated from hospital traffic.

McConnell Dowell's building brand, Built Environs, was the Managing Contractor for the Modbury Hospital Upgrade – one of the most complex hospital redevelopments undertaken in South Australia.

This program of work was focussed on improving access to patient care and enhancing the design of the hospital to meet contemporary needs and models of care.

The historic building is five stories tall so a seismic retrofit to comply with the Auckland Council earthquake code, was always going to be a challenge.

The solution the engineers and Mechanical came up with was to install independent structural support at each story to strengthen the entire building and meet the code.
