Bridge management and decision-making perspectives

<p>In existing infrastructure management, bias between practice and scientific developments could be decreased by proper communication between practitioners and academia. IABSE TG5.4 aimed at evidencing this gap. This work focuses on the decision-making complexity for Bridge Management, to point out recent trends related to research fields, extending an initial analysis related to a survey on implemented decision-making models. The results and conclusions of this work are derived from the interviews conducted by TG5.4 experts, composed by academics, owners/operators, consultants, with country-specific infrastructure stakeholders from Europe, the USA, and South America. Knowledge and limitations on bridge management and decision-making related to technical, economic, environmental, social, political issues and fragmentation of the sector are addressed. Strengths/weaknesses of digitalization and areas for future works are identified.</p>
