This report is part of the H2020 CSA IM-SAFE project results and is the outcome of WP3 (Datainformed
safety evaluation and maintenance strategies) Task 3.1 (Safety evaluations and risk
management methods) activities, listed as delivery D 3.1. It constructs a part of the technical
background for the formulation of the proposal for the mandate to CEN for a further amendment to the
existing EU standards on data-informed safety assessment taking into account inspections, monitoring
and testing and for a new standard for preventive maintenance of transport infrastructure.
This report includes the review of the methodologies for performance assessment, including datainformed
approaches, the review of the damage indicators (DIs) and performance indicators (PIs) 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.
