Chiswick Bridge Refurbishment

Chiswick Bridge, Chiswick

15 Months

Project Overview:

The refurbishment of Chiswick Bridge required the re-engineering of the Grade II listed Portland stone parapets. The scheme included the reinforcement of the stone parapet, whilst retaining the existing stonework members, in order to comply with N1 impact containment. Due to the heritage status of the bridge, all deconstructed stonework was returned back to it's original position.

To undertake the stone work replacement , Alltask used an innovative method of over water access by using a hanging cantilever scaffold from a series of steel columns located along the length of the structure. This steel work was also used to provide a runner beam directly over the parapet alignment. This runner beam, together with associated lifting chains, was used as a gantry crane to lift and move the stonework. This solution limited manual handling of these heavy stonework elements.
