Aging timber bridges in Australia are a prevalent issue which impact governments at both the state and council level. Aging timber bridge replacement is a costly and complex process. Selection of a replacement alternative is a multifaceted and binding task. This research will undertake a comparison between available modular bridge systems using a lifecycle, multi criteria analysis. The overall objective is to determine the most appropriate modular bridge systems used for bridge rehabilitation / replacement in various applications. A deliverable of this research will be a decision spreadsheet whereby, it will assess the bridge systems from a life cycle approach, assessing procurement, construction, maintenance and decommissioning. The scope of the research shall be limited to the bridge superstructure and a maximum span distance of 20m, it will also be reduced to local government roads which experience moderate traffic loading.
This research will benefit governments/asset owners in the selection of the most appropriate modular bridge system which will be used in timber bridge replacement / rehabilitation. It will allow selection of the most appropriate modular bridge system for an array of discerning criteria which will enable the most cost effective and structurally sufficient bridge.
