On the night of 5th September 2014 a road-train transporting 52 tonnes of ammonium nitrate crashed next to the Angellala Creek Bridge. The bridge is approximately 30km south of Charleville, on the Mitchell Highway in outback Queensland. The incident destroyed the road bridge and adjacent rail bridge and has been described by the Queensland Department of Natural Resources and Mines, as the most powerful explosion in Australian Transport History.\n\n

This paper initially outlines how the Department of Transport and Main Roads’ (TMR) Engineering and Technology Branch (E&T) delivered a project that elevated the standard of Australian engineering and responding to the short and long term needs of a community following an extreme emergency event. The purpose of this paper is to discuss E&T's delivery of the project implementing digital engineering and Building Information Modelling (BIM) throughout the design, construction, and post-construction stages. The application of BIM presented an opportunity to manage the project efficiently and effectively to ensure the robust management of the asset throughout its construction and future operational life.\n\n

The use of digital engineering and BIM resulted in a four week turnaround in the design of numerous concurrent options satisfying a number of scenarios (height, width, and length). This presented the Principal with a number of arrangements from the available construction drawings and allowed the Department to realise the benefits of increasing the flood immunity with accurate cost estimates.\n\n

E&T applied industry best practises to ensure an extraordinary response was provided for an extraordinary event.
