Capability Statement

In an alliance with Brisbane Water we upgraded the Lake Manchester Dam, 25 km west of Brisbane, to meet current Australian National Committee on Large Dams (ANCOLD) guidelines. The inherent instability of the dam structure required some imaginative approaches.

The safety issues needing rectification included inadequate spillway capacity; the potential instability of the dam when water levels reached the crest of the dam; the possibility of the washing out of the downstream toe of the dam during major flood events; and potential erosion problems in the ‘plunge pool’ of the spillway.

In joint venture with Diona (the Water North JV) we're one of three major framework partners delivering SA Water’s multi-billion dollar capital delivery program. The 'Frameworks' model fosters collaboration and innovation in the planning and delivery of water projects across metro and regional South Australia.

During the first four years (2020 - 24) our team delivered approximately 150 projects, including the design and construction of:

We improved the safety and performance of one of the largest dams in the Southern Hemisphere for the NSW state government. They selected us based on the quality of our technical solution, our approach to protecting the sensitive river environment, and our strategies for minimising impacts on the nearby tourist park.

We secured the project after an extensive pre-qualification and competative early tender involvement (ETI) process.

We proposed and implemented an alternative construction approach for the Meander Dam project, with our roller compacted concrete (RCC) solution reducing environmental risk and delivering cost, productivity and program benefits for the Tasmanian Government.

Roller-compacted concrete (RCC) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios. The drier mix has many time and cost benefits over conventional mass concrete, including higher rates of concrete placement, lower material costs, and lower costs associated with post-cooling and formwork

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.

As the principal contractor within the Southern Regional Water Pipeline Alliance, we designed and delivered a new 200-megalitre-per-day water grid on a fast-track program to support the rapidly growing population of South East Queensland.

The project was delivered during the worst drought on record, with Brisbane's water storages at less than 15 percent capacity. This 'need for speed' necessitated concurrent progress in land access, design, approvals, and procurement.

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.

Achieving an average daily pipe-laying rate of 1.25 km (peaking at 3.1 km), we constructed this 217 km long, large diameter water pipeline on a fast-track program for Sunwater.

The pipeline delivers 16,800 ML of water per annum to a terminal storage at Moranbah to be used predominately by industry. The new water supply ensures the continued prosperity of the Bowen Basin Region.

We are constructing the Kidston Pumped Storage Hydro Project in Far North Queensland - an innovative project that involves the world-first conversion of a disused gold mine into a pumped storage hydroelectric power generation facility.

This first-of-its-kind natural battery storage facility has the potential to generate up to 250 MW of rapid response (less than 30 seconds), flexible power to Australia’s National Electricity Market.

Awarded the design and construct contract for the Bogong Power Development Project by AGL, our engineers set about developing smart design and construction strategies that ultimately reduced the project cost by A$30 million.

Consisting of a network of tunnels and shafts and the construction of a new underground hydro electric power station, the Bogong Power Development Project is the largest hydro power project constructed in Australia in 25 years.

We undertook repair works on the diversion gate and tunnel at the 80 year old Arapuni Dam on the Waikato River, developing a number of innovations to save time and cost.

Our scope of works included the mechanical refit of the diversion gate to improve reliability, reduce leakage and extend the life of the gate by a further 50 years.

We rehabilitated the Ambuklao and Binga hydro electric powerplants for SN Aboitiz Power-Benguet (SNAP), combining expert project knowledge with proven construction techniques to complete the projects safely and efficiently.

Ambuklao was first commissioned in 1956, while the downstream Binga plant was commissioned in 1960. Both were shutdown in 1999 due to damage from an earlier earthquake.

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.

In joint venture, we designed, constructed and commissioned the 166 MW Te Mihi Geothermal Power Station, replacing the world's second largest power station - the 50 year old Wairakei Power Station.

With limited experience in complex EPC contracts in New Zealand, the joint venture, comprising ourselves, SNC Lavalin, and Parsons Brinckerhoff, brought together a strong team with extensive international expertise in power plants, to meet Contact Energy's specific requirements.
