Dinting Vale Viaduct

This five-span viaduct was built in 1860 and each span consists of two wrought iron box girders between tall masonry piers, with an overall length of 209.3m. Over the years the viaduct has been strengthened and recent examinations revealed that some work needed to be completed to prevent damage to the original structure and meet the client’s operational requirements.

Added Value

Through our wealth of experience and innovative approach to projects, Taziker accomplished the strengthening work with the minimum of disruption. The historic fabric of the bridge has been preserved and all issues with the strength of the structure have been rectified. Through our works, the need for drastic future intervention has been greatly reduced; contributing to reducing the whole life cost of the viaduct for Network Rail.

Learning and Innovation

Taziker had recently completed the refurbishment of the nearly identical Mottram Viaduct structure and we were able to utilise lessons learned as part of that project to this one. We were in a better position to take a much more educated view on problems that we may face at different stages of the project and how we can plan to address these.

Replacing the timber packers with new pot bearings represented a significant challenge to overcome. An innovative temporary works design allowed the bridge to be supported on a ‘goal post’ arrangement under live load. This meant that the jacking works were able to be carried out under a standard eight hour weekend possession; eliminating disruption to services.
