The objective of this research was to develop and evaluate a methodology for measuring the effect of various bridge deck replacement methods on the total cost, schedule, and road user costs of a bridge project. Steps are outlined for data collection, normalizing, and nested ANOVA statistical analysis of created construction performance factors: unit cost, production rate, and road user cost. A contractor exit survey was developed to gather vital information on a bridge project that may not be reflected in the raw collected data. A hypothetical example problem was created which demonstrated how the methodology and analysis outlined can be used to aid engineers in justifiably selecting the most viable bridge deck replacement method(s) to use on future projects, based upon regional constraints and agency priorities.
