Wollaston Bridge Construction

Wollaston Bridge Construction

The Woolaston Bridge Construction scheme forms a crucial part of a large housing development known as Doulton Brook on the site of a former medical facilities complex building. The project proved to be challenging to deliver as a number of house builds were in progress when Fitzgerald were awarded the contract to construct the bridge. The River Stour which had been culverted previously had been re-channelised and the new bridge construction would provide a link between the  two sides of the housing development, indeed during construction there was one sole permanent access to the site. Throughout the duration of the scheme access was gained to both sides by using a temporary access which was subsequently decommissioned at contract completion.

The scope of works included:
• Installation of cofferdams and excavation of abutments onto founding rock, and construction of the bridge base
• Reinforced concrete works to the  bridge abutments and wingwalls by a series of sequenced pours, which alternated between abutments
• Crane installation of precast deck beams
• Casting of main deck and parapet edge beams
• Construction of footways across the bridge
• Surfacing works across the bridge
• Installation of mechanical expansion joints at the ends of the deck
• Provision of parapets to the main span and wing walls
• Silane waterproofing and anti-graffiti paint applied to exposed concrete surfaces
• Scour protection armour below and on the river approaches to the bridge

  • Highways Structures
  • Housing Infrastructure
