Bridge risk management, online

About this event

The overall management of bridges throughout the UK has, to date, generally represented good practice and has resulted in relatively few collapses.

However, the management of hidden defects in bridges has been largely reactive, with action only taken once the deterioration becomes visible. A notable example of the risk inherent in this approach occurred in 2009, when the Stewarton Rail Bridge collapsed due to extensive steelwork corrosion in an area buried under ballast. This incident led to the development of a wider programme which identified, and then inspected, over 40,000 bridge spans containing hidden critical elements. 

Our expert panel will shed light on their holistic approach to the Asset Management and Risk Management of highway structures, from inspections through to investigation, monitoring, repair and assessment. 

There will be a focus on hidden critical element (HCE) investigation and an overview of how to manage and monitor structures with HCEs effectively, to avoid unforeseen structural issues such as those which occurred during the Stewarton collapse. 

The presentation will also cover the on-site application of detecting hidden defects, involving ground penetrating radar and tomography for detecting voids in concrete elements and post-tensioned ducts. 

This event is organised and hosted by the ICE Merseyside branch.
