Earlier this month Hazell Bros Concrete had a milestone achievement by pouring a pile that’s claimed by McConnell Dowell (Head Contractor) as the deepest drilled pile in the southern hemisphere as part of the new Bridgewater Bridge Project. The pile had an overall depth of 90m with a 2.4m diameter. We had a continuous pour for 10 hours and supplied 426m3 (71 truckloads) of concrete to this single pile which is equivalent to 1,100 tonnes of concrete.

The supply was fulfilled by utilizing our two concrete batch plants at Bridgewater and ten agitator trucks with a direct team effort of 15 concrete workers and 4 QualTech testers. The pile utilised one of the most technically challenging concrete mixes that was designed in conjunction with QualTech. The whole 71 truck loads that went to this pile were both visually and physically assessed for their compliance.

As a risk mitigation, before commencement of the pour, the stockpiles and cement storage were at its maximum of 600 tonnes of aggregate and over 400 tonnes of cementitious materials respectively, and during the pour day we had received 7 tankers of cementitious material (157 tonnes) and around 450 tonnes of aggregates from our quarry.

Great team effort and collaboration between Concrete, Quarry, Transport and QualTech, a true example of vertically integrated management model of Hazell Bros!

Hazell Bros is proud to be part of the New Bridgewater Bridge project, one of the most recent significant infrastructure projects delivered in Tasmania. Hazell Bros, in conjunction with its affiliated testing laboratory QualTech TAS, has designed a technically challenging concrete mix for this project. Engaged by lead contractor McConnell Dowell, Hazell Bros will provide nearly 120,000 tonnes of concrete to the project.
