The reopening of the flood-damaged Tadcaster Bridge in North Yorkshire was a particular source of pride for the Keller staff who played their part in repairing the 300-year-old structure.
Project manager Mick Moore and his team spent eight weeks on site installing piles under one of the piers that was severely damaged when the bridge collapsed during flooding in December 2015, cutting the town in two.
“We were delighted to be involved in the works on the bridge and helping to reconnect the town of Tadcaster, “ said Mick.
“It was great to see the joy of the townsfolk when the bridge reopened.”
The Keller team used rotary bored piling to construct a secant wall to install a cofferdam around the damaged pier. Once the cofferdam was in place, Pali Radice mini piles were then installed to stabilise the pier.
“In the end, we installed 12 inclined piles on pier 5 (the one that suffered the most damage) and six vertical ones between the inclined ones. We also installed 35 piles to construct the secant walls for the cofferdam along with 20 bearing piles for new pier base.”
“Once works to Pier 5 were complete, Keller was asked to install a further 12 inclined Pali Radice piles to the existing Pier 6 from bridge deck level through the pier to compensate for any differential settlement that may occur now that pier 5 was stabilised.
“These works were carried out as main contractor Balfour Beatty were rebuilding the new section of Pier 5 and were also undertaken utilising two crews working 12-hour day and night shifts over two visits to site ensuring these additional works were also complete in time for the bridge opening.”
After Mick and his team completed their work, Balfour Beatty moved in to complete the stone work before the reopening on February 3.
Don Mackenzie, North Yorkshire County Council's executive member for highways, said: "I am very proud of the enormous effort made by our contractors and our bridges team to complete a very challenging project of this kind in little more than half the time it would normally take."
Keller’s work attracted national exposure when it was featured on the BBC evening news as part of a report on flood defences last September and again on The One Show ahead of the reopening.
Prime Minister Theresa May also thanked the team "who worked so hard to restore the bridge" in the Houses of Parliament and praised the people of Tadcaster for putting up with the disruption the bridge collapse caused.
