ABSTRACT

An economic evaluation is an important step in the decision-making process for work that involves major expenditures. At the project level, the costs for alternative levels of improvements to a bridge are compared to determine the most economical option for the bridge based on either the present value analysis or the incremental benefit/cost ratio analysis. At the network level, the costs for different levels of improvements for all the bridges in the network are compared to prioritize work based on the incremental cost/ benefit ratio analysis.
