Zoom Webinar , Online, QLD CIA


In this seminar our speakers will explore bridge failures, what went wrong and the critical role of maintenance planning in the early design process. We will review the bridge design and maintenance planning requirements of our roading authorities in Queensland and more broadly across Australia highlighting the importance of ‘getting it right the first time’ to minimise unplanned maintenance and associated costs. Revisiting how and why bridge durability and design life must be achieved, we learn more about consequences, including legal, associated costs and social impacts of poor maintenance planning. Different bridge types represent different structural challenges and will review why a ‘one size doesn’t fit all’ when planning maintenance. Modifying a maintenance plan for different bridge types is crucial and this detail must be built into every design, early in the process. We will look at what parts of bridges continue to require regular maintenance and repair, why, and what we need to consider to achieve our long design lives.
