An engineering feat was carried out by Thiess John Holland on February 25, 2010 with a 15-hour operation to lay 2,800 cubic metres of concrete. The pour completed a section of the Airport Link tunnel roof in Kedron, Brisbane's north. A team of more than 50 people worked round the clock to undertake one continuous pour - the largest concrete pour to be undertaken for construction of the Airport Link Project. A total of 380 concrete trucks will be used for the pour, approximately 37 trucks every hour, requiring meticulous planning and scheduling of vehicle deliveries to the Kedron site.
