About the research

Recent advancement in bridge construction technologies, especially with respect to bridge decks and superstructures, have become commonplace in new bridge projects. Substructure construction has not made the same advancements, however. There are existing technologies that have potential for simplifying and expediting the construction of bridge substructures at the same or reduced cost using equipment that is more readily available. In this project, helical pile foundation implementation for bridges will be investigated and a design guide will be produced. This tool will give engineers direction for alternative deep foundation options on bridge structures. This is an advantage for any bridge project, but particularly for low-volume roads where budgetary considerations tend to be of specific priority.
