We received the Australian construction industry's highest accolade for this major wharf redevelopment within Melbourne's main port precinct.

This was a large and complex marine project delivered within Australia's busiest operational container port, and within very tight environmental controls to protect the rich marine life within the surrounding bay.

Working in collaboration with the Port of Melbourne, we successfully completed four contracts at Swanson Dock between 2017 and 2020.

After completing the award winning Port Capacity Project, we continued our partnership with Port of Melbourne with a series of smaller contracts to rehabilitate the iconic Swanson Dock - the heart of Australia's busiest container terminal.

We recently completed Stage 1 of the Swanson Dock West Remediation, and are now delivering Stage 2. This is our sixth project for Port of Melbourne since 2017.

Swanson Dock West (SDW) is a critical International Container Terminal comprising of a 944 m wharf with three container-handling berths, which were constructed in several stages between the 1960s and 1980s. The existing wharf is of varying forms of construction and some sections are close to or beyond the typical design life of 30 years. As a result, major remediation was needed.

Drawing on our industry-leading trenchless construction experience, we delivered the Warkworth to Snells Transfer Pipeline for Watercare, continuing our strong relationship with them.

The project was part of Watercare's North-East Wastewater Servicing Scheme, which conveyed wastewater from Warkworth to Snells Beach. The scheme will cater for future growth and enable Watercare to decommission the existing Warkworth Wastewater Treatment Plant, which discharges into the Mahurangi River.

Using an innovative caisson (sunk shaft) construction method, we designed and delivered the Warkworth Pump Station, part of Watercare's broader scheme to improve the wastewater network from Warkworth to Snells Beach.

We built the new 247 litre per second wet-well / dry-well pump station adjacent to an existing pump station in Lucy Moore Memorial Park, implementing construction strategies and approaches to protect the sensitive park and river environment.

Proposing a trenchless solution to minimise disruption, Watercare Services awarded us the Snells Algies wastewater pipe and outfall construction project. It resulted in new world record - a 2021 metre long Direct Pipe® drive delivered using a micro tunnel boring machine.

The project was the first phase of a three-phased scheme to improve water quality in the Mahurangi Harbour and cater for population growth in the Warkworth and Mahurangi East communities north of Auckland.

We delivered this state-of-the-art wastewater treatment plant upgrade in Auckland, drawing on our learnings from past projects to value-engineer the design and fast-track the programme. We delivered the project on time and within budget, all while keeping the existing plant fully operational.

We were engaged (in joint venture) by Watercare to upgrade the Pukekohe Wastewater Treatment Plant to support population growth in Franklin, and improve the quality of the water discharged into the Waikato River.

In joint venture, we delivered an additional Biological Nutrient Removal (BNR) facility for Watercare, streamlining the programme and providing alternate solutions that reduced the cost of this complex brownfield project. The facilty provides additional secondary treatment capacity for approximately 250,000 people.

The project, which was part of Watercare's expansion of their Māngere Resource Recovery Facility (MRRF) in Auckland, won a IPWEA 'Best Public Works Project' award.

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.

Using state-of-the-art Direct Pipe® tunnelling technology for the first time in New Zealand helped us mitigate the significant risks we faced on Watercare's Army Bay Ocean Outfall project.

They engaged us to design and construct a new wastewater outfall, upgrade an existing pump station, and build a new ultraviolet disinfection facility to increase the outfall capacity of their Army Bay Wastewater Treatment Plant at Shakespear Regional Park.

We're delivering the Eyre Peninsula Desalination Plant Marine Works for SA Water.

This project plays a key role in supporting a more reliable and climate independent water supply for the Eyre Peninsula, reducing reliance on the Uley South Basin and preparing the region for future growth.

We designed and constructed the final section of Auckland's biggest water pipeline project, re-routing the pipeline to minimise impacts, and completing New Zealand's longest ever pipe-jack.

The 32 km long Hūnua 4 project connects Watercare’s reservoirs in Manukau to central city water storage, improving the capacity and the resilience of the city's water network.

We upgraded Glen Eden's wastewater infrastructure, using innovative construction methods to reduce our footprint and lessen the impact on residents. The network upgrades have reduced the number of overflows that occur following prolonged heavy rains.

The design and construction of a 2 million-litre storage tank under an existing car park in Harold Moody Reserve using a caisson method was a creative solution to space constraints..We also used trenchless tunnelling methods to install the new pipelines, minimising disruption to residents living on Glendale Road.

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 introduced new tunnelling techniques and lining systems to New Zealand when we replaced the 90 year old sewage pipe crossing Hobson Bay on Auckland's waterfront. And we delivered it ahead of schedule.

The new tunnel increases sewerage capacity for projected population growth and prevents wastewater overflows into the bay and Waitemata Harbour basin, a popular swimming and boating spot.

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.

We designed and constructed the marine structures for BCI Minerals’ Mardie Salt & Potash Project in Western Australia, using our innovative canti-traveller system for speed and low impact delivery.

The 'Mardie' Project is a large-scale, solar evaporation operation on the Pilbara coast. Capacity of the completed facility is estimated to be 5.35 million tonnes per annum of high purity salt and 140,000 tonnes per annum of sulphate of potash, over an operating life of at least 60 years.
