The Project
We were appointed to deliver a new road bridge on Wharford Lane, spanning both sides of the brook to facilitate access to a new housing development.
This project involved removing the existing temporary bridge abutments where they conflicted with the proposed bridge foundations. The scope of work included piling, associated civil engineering works, and the construction of new abutments and bridge superstructure.
In order to progress the works, we obtained a bespoke permit from the Environment Agency which required us to make improvements to the channel up and downstream of the works.
Key activities included the installation of temporary and permanent formwork, the construction of the bridge deck, waterproofing, surfacing, kerbing, and the installation of parapets. The new 18.5-metre-wide, 11.95-metre-long, and 200mm-thick reinforced bridge deck was supported by reinforced concrete abutments and piles. A total of 34 steel H piles (18 metres long, 203 x 203 x 60UC) were installed.
The concrete deck was mounted on Permadec decking boards, with three sections positioned lower to accommodate the installation of 3 x 150mm electric ducts, 2 x 225mm water ducts, 1 x 150mm gas duct, and 1 x 94mm data duct, all laid an additional 3 metres to either side of the bridge deck.
Waterproofing was completed before the installation of the new kerbing and full tarmac construction. Varley Gulliver handrails were subsequently installed on the reinforced concrete parapets.
The bridge incorporated landscape strips and a bridleway as well the carriageway and two footpaths.
