A problem with a concrete pour has delayed a £15M Scottish flood defence scheme after a “bendy bridge” had to be replaced.
Construction of Perth and Kincross Council’s £14.7M flood defence scheme will not be complete for another four months as contractor Balfour Beatty’s newly built, 10m long bridge across the River Almond has been demolished.
The Almondbank Flood Protection scheme is already running 14 months behind schedule after problems finalising designs delayed the start of the second stage of works in 2016. A council spokesperson described the scheme’s original December 2016 completion deadline as “ambitious”.
Temporary supports for the new bridge deck moved while concrete was being poured, leaving it with defects which only became apparent after the moulds had been removed. According to Scottish newspaper Daily Record, residents became concerned by the “bendy in the middle” bridge when it opened late last year.
Structural assessments were carried out to assess whether the single carriageway bridge could remain in its as-built state, but it was decided that it had to be demolished and rebuilt.
A Balfour Beatty spokesperson said: “We have been working hard to overcome the challenges encountered on the Almondbank Flood Protection scheme with Perth and Kinross Council. Due to a defect which occurred while pouring concrete into the deck mould, it has been necessary to demolish and rebuild the Confluence Bridge to ensure quality and structural integrity.
“Additional works will be undertaken at no additional cost to the council and we apologise for any inconvenience caused. These works will not delay completion of the scheme.”
The Almondbank Flood Protection scheme aims to mitigate regular flooding around the River Almond.
