Abstract:
The Bakewell Underpass, which is currently under construction in Mile End, Adelaide, South Australia, is an extremely complex engineering project, comprised almost entirely of concrete elements. The project is one of the first to be delivered by the “ECI” (Early Contractor Involvement) delivery method in Australia. It involves the replacement of an 80 year old concrete road bridge with a new 4 lane twin deck underpass. The underpass deck structures accommodate the main suburban and interstate rail lines and a busy commercial road near the edge of the CBD. The most unusual feature of the project is the super-tee rail bridge deck, which has been designed to be launched into place during a four day track occupation, thus minimising disruption to the critical train services. The rail bridge deck, is constructed entirely offline with preparatory piling and headstock construction undertaken during short occupations.
