Butts Bridge, Alton: Cill Beam Installation

Bespoke precast concrete cill beams, design by Jubb, were landed on the east and west abutments of the new Whitedown Lane Railway Bridge in Alton on Tuesday (21st May). Harry Giblin, Jubb Structural Engineer, was present to witness the install and provide guidance to the contractor. The beams had been successfully transported form Northern Ireland and were placed with millimetre precision. Jubb chose to use precast concrete for the beams due to the detailing and high quality of finish required to ensure the bridge structure reaches (and exceeds) its 120 year serviceable life. With the substructure now mostly complete, the steelwork for the deck will soon be taking shape.
