Short term planning methods for infrastructure maintenance and renovation works

Abstract

The examples of three infrastructure assets, namely dams, road bridges and water networks illustrate how risk management principles can lead to various prioritization methods for annual maintenance and renovation works: « hazard analysis » of dams, the Sétra method for road bridges, and the MEDIREL method implemented for the water network in Lausanne. These methodologies are presented according to the vulnerable issues exposed to possible failures, hazard characterization, and the prioritization of actions aiming at risk mitigation in the short term.
