This paper focuses on the
development of a precast substructure system for standard bridges focusing on
element shapes, substructure configurations and the construction and erection
options. The process of choosing the final system and its details is presented
through a review of decisions regarding aesthetic appearance, efficient use of
materials and economical construction practice. Particular attention is given
to decisions pertinent to potential standardisation of the system with a focus
on introducing a creative, economical option. The process of developing this
system is presented to emphasise ways in which creativity can be introduced
into standard short- and moderate-span bridge design - a branch of structural
design that has stagnated with unattractive results in many parts of the world.
