Precast concrete substructures for Bridges

Incorporation of precast concrete is well-established at deck level where standardisation across individual structures is more intuitive. However, there are increasing trends worldwide towards incorporating precast elements in bridge substructures. ‘Substructure’ refers to all structural bridge elements below deck soffit or bearing level, i.e. foundations, abutments, retaining walls, piers, columns and crossheads.

This subject is key to the move towards carbon reduction of concrete bridges and is discussed in the CBDG´s publication TR17 Precast Concrete Substructure for Bridge Construction.
