The Refurbishment of Westminster Bridge: Assessment, Design, and Precontract Planning

This paper describes the assessment, investigation, design and precontract planning for the recently completed refurbishment of Westminster Bridge. The work described includes the analysis of the strength of wrought-iron and cast-iron components, an instrumented load test, and the design of strengthening works to enable the bridge to carry 40t vehicles. Particular features of the work include the adoption of a lightweight aggregate reinforced concrete deck structure and the development of facsimile replacement parapets and a bolt-type shear connector to introduce composite action bemeen the existing metalwork and the new deck. The precontract planning for the refurbishment of this strategically important transport link and national landmark in the heart of London is also described. R. Blakelock, S.R. Munson and D. Yeoeli
