Bridges

This paper presents a case study of the detailed bridge design delivery processes utilised for Portion A of the Woolgoolga to Ballina Pacific Highway Upgrade. Woolgoolga to Ballina is the final stage of the duplication of the Pacific Highway between Sydney and the Queensland border. Portion A included a 49km stretch of highway and 72 bridges within the single design package.

This paper outlines the processes that enabled the BG&E/GHD bridge team to deliver 43 bridge design lots (72 bridges), within strict program deadlines, to the required quality. The paper discusses the design and production management tools employed to enable the weekly issue of up to 300 detailed structural drawings; it will also outline the design team structure facilitating a dispersal of responsibility to allow for both redundancy and efficient communication. Finally, it will provide an overview of the design processes developed to allow for efficient design and change management.
