TURNER-FAIRBANK HIGHWAY RESEARCH CENTER Challenges in Measuring Bridge Performance • • It is not well defined and understood or documented Relies too heavily on expert opinion Based on significant assumption or generalization Uncertainties – Subjectivity of current condition ratings – Lack of proper documentation (i. e. , records of actions and costs, deferring the action) – Incomplete data (i. e. , cost, maintenance) – Many hidden deterioration and damage escape visual inspection
