Synthesis of Information Related to Highway Problems. Topic 47-03. Current Practices and Guidelines for the Reuse of Bridge Foundations

As demands for infrastructure continue to change and with bridge components deteriorating over time, bridge widening, rehabilitation, and replacement efforts will continue to increase. Depending on site conditions, bridge foundations typically comprise approximately 30 percent or more of the total highway bridge costs. Decisions on whether to reuse, retrofit, or replace existing foundations have a significant impact on the project budget. Reuse of bridge foundations may result in time savings, improved highway safety, and reduced traffic congestion. However, to consider a foundation for reuse, the integrity and capacity (structural and geotechnical) of the existing foundation elements must be reliably determined. The primary concerns with reusing existing bridge foundations are the ability to accurately assess their condition, load carrying capacity, and remaining service life, and the impacts on design codes. Procedures used to evaluate whether foundation reuse is viable for a particular bridge project differ among transportation agencies. A synthesis on current practices for foundation reuse in highway applications is timely as transportation agencies are facing this question more and more on bridge projects. The objective of this synthesis is to document current practices and guidelines used by state transportation agencies for the reuse of bridge foundations. The synthesis will identify strategies and methods that agencies have used to solve problems, as well as identify problems that remain largely unsolved. Information for this study will be gathered through literature review, a survey of state departments of transportation (DOTs), and follow-up interviews with agencies for case examples of their practices. Lessons learned, gaps in information, and suggestions for future research will be included.
