Bridge Quality Appraisal Methodology: Application in a Reinforced Concrete Overpass Roadway Bridge

Bridge quality control plans and asset management systems are often integrated in collective frameworks used by authorities nationally and internationally. Similarities among these frameworks include the utilization of performance indicators for quality appraisal. However, there are discrepancies in the ways such frameworks are researched, developed, and applied. Additionally, there are problematic aspects even in their common characteristics, like the relative absence of correlation between observed performance indicator values and benchmarked ones, and the deliverables’ disparity due to the diversity of the quantified indicator variables. For the alleviation of such problematic aspects, this paper presents a bridge quality appraisal methodological and computational framework. It builds on (1) the adaptation of the sustainable building methodology and its combination with expert input solicitation methods and the research findings of the European Cooperation in Science & Technology (COST) Action TU1406, and (2) a multi-input adaptation of the analytical hierarchy process. The methodology is presented in terms of its general procedural steps and calculating requirements, and then it is tailored to reinforced concrete overpass roadway bridges. The methodology’s application in a real case study concludes the presented research.
The scientific and financial support of COST Action TU1406 for the successful development of the framework of this research is gratefully acknowledged. In addition, the help and support of distinct colleagues at the Civil Engineering Department of the University of Minho is cordially acceded. Furthermore, the response of all the COST Action TU1406 colleagues and fellow engineers during the expert interviews stage (especially Mr. Sander Sein) and the questionnaire survey is kindly appreciated. Finally, the offered data, expert input, and invested time of the colleagues and fellow engineers of Infrastruturas de Portugal (and especially Dr. João Amado) are warmly acknowledged.
