Face lift

This article describes the replacement and refurbishment of hazardous cast iron fascia girders on Westminster Bridge, London, UK. Three major temporary work items were built in structural steel: pier towers standing on the bridge pier pile caps, which support loads; access bridges between the pier towers; and lifting trusses on slide beams at the top of the pier towers, allowing removal and installation of the fascias. Hangers from the lifting truss are attached to a fascia, which is then cut free and lowered into a pivot frame fixed on a barge: installation of a new fascia is carried out in reverse order. The new fascias are in spheroidal cast iron less prone to brittle fracture. Decorative spandrels at each end are being refurbished and re-installed. The fascia is made in individual panels which can be removed and replaced if necessary, with the bottom cornice cast as a separate section. The project is expected to be completed by the end of 2007.
