PIEVC Engineering Protocol

The Protocol systematically reviews historical climate information and projects the nature, severity and probability of future climate changes and events. It also establishes the adaptive capacity of an individual infrastructure as determined by its design, operation and maintenance. It includes an estimate of the severity of climate impacts on the components of the infrastructure (e.g., deterioration, damage or destruction) to enable the identification of higher risk components and the nature of the threat from the climate change impact. This information can be used to make informed engineering judgments on what components require adaptation as well as how to adapt them -- for example, design adjustments, changes to operational or maintenance procedures.

Since 2008, the Protocol has been applied to assess climate risks and vulnerabilities across a wide range of infrastructure systems in Canada including: buildings (residential, commercial and institutional); storm water/wastewater systems, roads and associated structures (e.g. bridges and culverts), water supply and management systems, electricity distribution and airport infrastructure. Over 100 infrastructure risk assessments have been completed as of January 2021.

The PIEVC Program Partnership encourages the use of the Protocol for all types of infrastructure going forward. It is available for use at no financial charge for any public infrastructure assessment project in Canada.

For more information on the PIEVC Protocol and its applications, please see the below paper, prepared for the 2021 Canadian Society of Civil Engineers Annual Conference (May 2021).
