Temporary Works Toolkit. Part 11: Temporary works associated with precast concrete bridge beam construction

Current highway bridge designs in the UK tend to favour either composite steel girders with a precast or in situ concrete deck for long spans, or precast concrete beams with an in situ concrete deck for spans of less than 40m. Relatively few bridge decks are nowadays cast in situ on a birdcage scaffold or spanning falsework structure.

This article considers temporary works, in particular the use of temporary supports, to precast concrete bridge beams during deck construction.

The article is aimed at permanent works designers involved with the design elements of this form of construction, as well as civil and structural engineering undergraduate students.
