About this event

In major upgrades and extensions of highway networks over the past sixty years, the use of post-tensioned concrete in structures has been found to be an economically competitive form of construction.

However, unexpected deterioration of post-tensioned concrete structures has become a major concern in many countries, despite established design and construction practices. As a result, significant expenditure has had to be diverted from capital works to the management of these structures.

This talk will outline of the performance of post-tensioned structures, the necessary reviews of investigations, reports, their processes and findings. The implications for bridge owners/managers, and the essential lessons learnt will be revealed. The application of the new national standard "BD 54/15 Management of post-tensioned concert bridges" will be presented.

Mouchel Consulting has been involved in the development and trialling of the draft standard since 2012 for Highways England. Workshops and seminars on the standard have been presented to bridge owners and managers.
