New Bald Hills plant is now open

Hymix has built a dedicated concrete plant in Bald Hills for Australia's largest ever transport infrastructure project-the $4.8 billion Brisbane Airport Link. As the major concrete supplier for the project's precast sections, the plant is expected to deliver more than 100,000 cubic metres over the next 2.5 years.


The state-of-the-art plant began production on 10 May 2009, with the Airport Link’s precast concrete factory located next door. As a single-alley production facility, it features six ground bins, a 250-tonne weigh-bin capacity and a 1500-tonne storage capacity. A new command batching system also allows the plant to produce loads at a rate of less than three minutes from the first materials run.


It’s an impressive rate of efficiency the plant has made full use of since concrete for the first precast panels was batched in June this year. “We are estimating production to really increase towards the end of July,” confirms Jim Venn, State Manager for Hymix Queensland. “By that stage, the plant will be manufacturing concrete at rates topping 200 cubic metres every day, solely for the Airport Link.”


The project is scheduled for completion in 2012 and has three major components. The first is a 6.7 kilometre link between Brisbane’s two biggest destinations: the CBD and the airport. This link includes a 5.25 kilometre tunnel; the largest and longest tunnel ever built in Australia, with three lanes in either direction. It also includes a 750-metre flyover above the notoriously congested Brisbane airport roundabout and a Northern bus-way.


Hymix was the first major supply contract for the Airport Link project. It was a collaborative achievement with Theiss John Holland, contracted to design and build the Airport Link and underpinned by Hymix’s commitment to supporting their brand new precast facility with a dedicated concrete plant.


The plant was also built with impressive speed. “From the original design to the first load of concrete batched on June 10, it took just nine months, including the time taken to satisfy all Airport Link, local Brisbane council and EPA requirements,” Jim explains.
The design of the plant closely replicates that of Hymix Coomera, built in 2008. Three agitator trucks are currently batching out of Bald Hills, but this number is expected to double as production increases for the Airport Link later this year.
