This report is part of the H2020 CSA IM-SAFE project results and is the outcome of WP3 (Data-informed safety evaluation and maintenance strategies). Task 3.0 (Safety evaluations and risk management methods) activities, listed as delivery D 3.1.

WP3 contributes to the identification of the normative gaps with regard to data-informed safety assessment, risk assessment and maintenance decision-making based on review of the current state-of-the-art as represented by standards, guidelines, other regulations as well as current practice and research. The particular focus of Task 3.1 is on data-informed assessment taking into account inspections, monitoring and testing.

This report includes the review of the methodologies for performance assessment, including data-informed approaches, the review of the damage indicators (Dls) and performance indicators (Pls) used for the management of infrastructure networks and infrastructure objects and the review of the methodologies for risk assessment and risk management of infrastructure networks and infrastructure
objects. The conclusions from the review are used to formulate suggestions with regard to developments in standardization of concepts and methods for assessment of existing structures, including a proposal for the framework for data-informed assessment of transport infrastructure.
