Hazell Bros Concrete was awarded the contract for the concrete supply for the New Bridgewater Bridge by McConnel Dowell in 2022. The supply includes the concrete for piles, piers, bridge segments and all other civil works.

We worked closely with QualTech TAS, our NATA accredited testing laboratory who designed some of the most technically challenging concrete mixes to ensure the successful delivery of the project. Hazell Bros Concrete will supply / (has supplied) in excess of 47,000m3 of concrete for the entire project (approximately 120,000 tonnes).

Key Highlights for the Concrete Supply:

• Concrete for 46 marine piles including an 89m deep pile (believed to be the deepest drilled pile in the Southern Hemisphere)
• Concrete for 42 piers and cross heads
• Concrete for 1082 precast segments
• Concrete for two land bridges at both sides of the bridge.
• Concrete for all associated civil works
• All the major mixes designed by QualTech TAS are made of GP Cement and other Supplementary Cementitious Materials with a combination of either a Triple Blend or Double Blend concrete. This contributes to producing the most durable concrete for the conditions and lowering the carbon footprint.
• Two concrete batch plants entirely dedicated for the supply of concrete to the project situated at Bridgewater along with our batch plant at Lampton Avenue acting as our backup plant. One of the two concrete batch plants is the only large commercial wet mix plant operating in Tasmania.
• High quality stone used in the concrete was sourced from Hazell Bros Quarry located at Leslie Vale, and Hazell Bros Transport played a major role in getting large quantities of materials to the batch plant site in a timely manner.

This project is a prime example of Hazell Bros’ vertically integrated business model, showcasing the seamless collaboration between our Concrete, Quarry, and Transport divisions, as well as our testing laboratory, QualTech TAS. It also highlights the successful partnership between the head contractor and subcontractor, working together to deliver an iconic, high-quality outcome.
