An accident shortly before the Queen’s Jubilee celebrations, resulted  in Topbond being asked to carry out some emergency repairs to Westminster Bridge.

Strong currents had caused a cruise boat to crash into the bridge causing damage to one of the spans.  Topbond had already been  commissioned to undertake repairs to damage caused by a previous collision back in 2010 and had appointed  cast iron repair specialists to undertake repairs to the Grade II listed structure.

Because of the upcoming Jubilee, Topbond had to mobilise its marine  services team at very short notice to get both the original damage and the new damage completed before the Thames was used as part of the Jubilee celebrations.

In order to undertake the repairs, Topbond had to arrange for the closure to navigation of one arch of the bridge in accordance with Port of London procedures.  A safety boat was also in attendance while works were undertaken on the outside of the bridge.

Access was achieved by a combination of traditional scaffolding and cherry pickers , with the cherry picker working from a multi-cat craft.
