My Speaker Sessions
|Wednesday, December 01|
An outline of the performance of post-tensioned structures, the necessary reviews, findings and the essential lessons learnt will be presented.
WSP’s Structures Investigation Group (SIG) was involved in the development of the draft standard “BD 54/XX Management of post-tensioned concrete bridges” from 2012 and trialled the application of the BD’s processes, from desk studies to site investigations, on post-tensioned bridges during 2013 and 2014.
BD 54/15 was published in April 2015 and was a major improvement on the 1993 documents. The WSP SIG team completed BD 54/15 risk review and risk assessment reports for over 340 post-tensioned bridges between 2015 and 2021 and authored the re-drafted Standard, CS 465, as part of the update of the DMRB. CS 465 was a further improvement in the advice provided for the management of post-tensioned concrete bridges.
The development of the BD and CS documents will be outlined and the benefits of their application to certain bridges in Scotland will be presented.
